Published: May 2020

The accumulation of heavy metals such as Cd, Mn and Ni was investigated in seven different vegetables, fruits and soil samples from Thohoyandou, Limpopo Province, South Africa. Heavy metals were quantified using graphite furnace atomic absorption spectrometry. Concentrations of heavy metals in fruits and vegetables were in the range of 0.23–2.94 mg∙kg-1 for Cd, 11.72–50.16 mg∙kg-1 for Mn and 5.73 – 44.11 mg∙kg-1 for Ni on a dry weight basis. Analysis of soils from where fruits and vegetables were sampled showed that Cd in the soil was in the range of 0.08–1.07 mg∙kg-1, Mn levels were 204.99–249.13 mg∙kg-1 and Ni levels were 48.47–88.23 mg∙kg-1. Cd was below the instrument detection limit for soils on which onions and bananas were grown. Vegetables showed different accumulation abilities, with leafy vegetables being the highest accumulators of heavy metals. The obtained results showed that concentrations of Cd in fruits, vegetables and soils exceeded the recommended maximum acceptable levels proposed by FAO/WHO and, hence, may pose a health risk to consumers. Ni concentrations in bananas, onion, beetroot, spinach and Chinese cabbage exceeded recommended standards by FAO/WHO.
Biosorption of phenol by modified dead leaves of Posidonia oceanica immobilized in calcium alginate beads: Optimal experimental parameters using central composite design
Authors: Wassila Lazli  , Amina Hellal
Published: May 2020

This study reports the biosorption of phenol using dead leaves of Posidonia oceanica (PO), an endemic seagrass in the Mediterranean Sea. The PO dead leaves were pre-treated with sulfuric acid and carbonized at 500°C for 2 h to increase their adsorptive capacity. Leaves were then immobilized in calcium alginate beads to address problems that arise when free particulate biosorbents are used. Response surface methodology (RSM) based on central composite design (CCD) was carried out to optimize key variables, viz., initial phenol concentration (100–500 mg/L), biosorbent dosage (0.05–0.1 g/50 mL), and alginate beads to solution ratio (1/10–2/10). The effect of the operating variables on phenol biosorption capacity was studied in a batch system and a mathematical model showing the influence of each variable and their interactions was obtained. The predicted second-order quadratic model for the response variable was significant (p < 0.01). Further, an adjusted squared correlation coefficient, R2 (adj) of 97.7% indicated a satisfactory fit of the model. The results of CCD showed maximum biosorption capacity of about 127 mg/g at 500 mg/L initial phenol concentration, 1 g/L biosorbent dosage, and at 1.85/10 composite beads to solution ratio. This work demonstrates the suitability of using PO dead leaves as an effective low-cost biosorbent for the removal of phenol.

Best Practices for Adapting and Delivering Community-Based Yoga for People with Traumatic Brain Injury in the United States and Canada
Authors: Chauhan Nirali , Zeller Shilo , Donnelly Kyla Z.
Published: May 2020

Emerging benefits of yoga for traumatic brain injury (TBI) suggest that broader accessibility to community-based yoga programming is important. This cross-sectional, mixed methods study sought to identify best practices for adapting and delivering community-based yoga to people with TBI. An online survey was sent to 175 yoga teachers trained to teach LoveYourBrain Yoga, a community-based, 6-week, manualized program for people with TBI and their care-givers. The survey instrument included open- and closed-text questions assessing teachers’ perspectives on the most and least helpful adaptions for asana, meditation, pranayama, and group discussion, and on the LoveYourBrain Yoga training and support. Responses we re analyzed using d e s c r i p t i ve statistics and qualitative content analysis. Eighty-six teachers (50%) responded. Best practices for adapting yoga for TBI revealed six themes: (1) simple, slow, and repeated; (2) creating a safe space; (3) position of the head and neck; (4) demonstration; (5) importance of props; and (6) special considerations for yoga studios. Three themes emerged for yoga program delivery: (1) structured yet flexible; (2) acceptability of compensation; and (3) time management. Eighty-nine percent of teachers reported that the program manual was very/extremely helpful, yet nearly half (49%) adapted the manual content often/always. To deliver community-based yoga services for TBI, we recommend an environment with props, low light and noise, and sufficient space, along with the facilitation of consistent instruction with a manual that allows for flexibility. We recommend that yoga teachers have skills in physical modifications for the head and neck; slow, simple, and repeated cueing to facilitate cognitive processing; managing challenging behaviors through redirection techniques; and promoting safety through inclusivity, compassion, and personal agency.
Settler/Colonial Violences: Black and Indigenous Coalition Possibilities through Intergroup Dialogue Methodology
Authors: John Kelsey Dayle , Brown Kimberly Williams
Published: May 2020

This essay collages theories (settler colonialism, transnational feminism, Black and Indigenous feminist thought, and critical theory) for the purpose of dialoguing together through land-based Black and Indigenous solidarities. In our dialogue, we invite readers to think about how choosing theories and identifying intentions is a methodology of coalition. We demonstrate how this might materialize in three coalition possibilities: faith communities, neoslavery for dispossession and erasure, and reimagining borders.
Reading Bodies, Writing Blackness: Anti-/Blackness and Nineteenth-Century Kanaka Maoli Literary Nationalism
Authors: Warren Joyce Pualani
Published: May 2020

This article examines texts by Prince Alexander Liholiho, Samuel Kamakau, King Kalākaua, and Queen Lili‘uokalani to trace a strand of nineteenth-century Kanaka Maoli literary nationalism which embraced figurative blackness as a means to combat settler colonial notions of physical, racial blackness as a trait that made Kānaka Maoli unfit for sovereignty. This essay intervenes in contemporary discussions of Black and Indigenous intersections, asking us to move beyond comparative understandings of the two and instead contemplate what we might gain by examining a particular context in which blackness is a constitutive, foundational element of Indigeneity.
Journalistiek oriëntalisme
Authors: Kuitenbrouwer Vincent
Published: May 2020

In the interwar period, the leading Dutch journalist C.K. Elout conducted two research trips to the Dutch East Indies for the newspaper Algemeen Handelsblad. This article studies Elout’s letters from his travels in the context of the growing journalistic interest in the Netherlands in colonial matters in the 1920s. The reason for this interest was the increase in information transferred between the Netherlands and South-east Asia as a result of new technologies and rising tensions in the Indies due to the emergence of the anticolonial movement. Through his letters, Elout intended to stimulate colonial reporting in the Netherlands, with the goal of strengthening overseas ties. Therefore, this corpus of texts can be seen as a form of journalistic orientalism in which the author extensively reflects on the differences between the West and the East. This article focuses on these reflections and demonstrates how they influenced Elout’s later commentary on the news from the Dutch East Indies.
Film Distribution in Occupied Belgium (1940–1944)
Authors: Vande Winkel Roel
Published: May 2020

The military successes achieved by the Wehrmacht in the first years of World War II, provided Nazi Germany with the opportunity to realise a long-dormant ambition of cultural hegemony. This article, focusing on film distribution in German-occupied Belgium (1940–1944), investigates the concrete steps that were taken to bring this new cultural order into practice and identifies the obstacles the German Propaganda Division (‘Propaganda-Abteilung Belgien’) encountered. Through various measures, the number of Belgian film distributors, and the number of films offered by them, were reduced. The market position of German film in general and of German film distributors Ufa and Tobis in particular, was fortified. Nevertheless, these measures did not lead to a complete German market monopoly. This would have been politically undesirable, but also turned out to be economically impossible. Towards the end of the war, the cultural, ideological, but also the undeniable economic mission to make German films as strong as possible in occupied Belgium, proved incompatible with the German war economy.

Authors: Mokhireva N.L. , Mirolyubov V.R. , Nizov V.A.
Published: May 2020

Promising areas of application of pigments obtained on the basis of industrial wastes and containing a number of impurities are considered. The quality of the pigment obtained by the alternative technology from iron-containing sludge was evaluated in comparison with the red iron oxide pigments of the KA TU 2322-166-05011907-98 (Russia) and YIPIN S130 (China) grades. Quality indicators are stated and analyzed relative to the requirements of TU 2322-166-05011907-98. Primer GF-021 was analyzed for compliance with GOST 25129-82 and for the presence of anticorrosion properties by the potentiodynamic method and in the salt spray chamber. Pigments in the composition of fine-grained concrete were investigated for their coloring ability and effect on strength characteristics at the age of 1, 3, 7, 28 days. Deviations and competitive advantages of the pigment obtained by alternative technology are determined with respect to the standard both in the composition of the primer GF-021 and in the composition of painted fine-grained concrete.

Authors: Messineva E.M. , Fetisov A.G. , Manuylova N.B.
Published: May 2020

The dynamics of the impact of the largest airport of the Russian Federation "Sheremetyevo International Airport (IAS)" on the quality of the surrounding air environment is analyzed using an example. The most important sources of atmospheric impact located on the territory of OJSC "MASH" at present, and the dynamics of emissions for 2010–2018, as well as changes in their component composition are indicated. Analysis of the implementation of the environmental policy of this enterprise showed that it is generally quite effective. A key indicator confirming this efficiency is a noticeable decrease in total emissions per 1000 passengers served, which allows MASH OJSC not to increase its total emissions, despite the ever-increasing passenger flow.

STUDENT SURVEY FOR HIGHER EDUCATION QUALITY – CHALLENGES TO DESIGN AND ANALYSE DATA
Authors: O. Torbas Oleksandr , V. Hloviuk Iryna , V. Malakhova Olga
Published: May 2020

Purpose of the study: The objective of this study was to present useful practical advice on the process of designing questionnaires for student surveys for higher education quality, as well as conducting such survey through the analysis of results of such survey that was held in National University "Odesa Law Academy".

Methodology: This research is based on the results of an anonymous online survey among 142 students of the Faculty of Advocacy of the National University "Odesa Law Academy", which was conducted in April 2017. The survey consisted of 29 questions. All questions were divided into 3 separate groups: assessment of academic discipline, assessment of lectures, and assessment of practical classes. Each group consisted of open-ended and closed-ended questions. Closed-ended questions were evaluated on a 10-point scale, where 1 is the lowest score, and 10 is the highest.

Main Findings: The research findings demonstrate that to increase the response rate of student it's better to reduce the number of questionnaires and questions in them. Also, the authors stated that the online form of survey is better than paper form (in aspects of accessibility, anonymity, and convenience for students). It was found that the vast majority of students' responses were received during the first days of the survey, which indicates that it is impractical to be conducting such a survey over a long period. It was found that in response to closed-ended questions most students chose the highest mark (10 out of 10), so developers of questionnaires have to choose another scale for closed-ended question assessment which has some real references. Also, it was stated that only a fraction of open-ended questions will contain really useful information that can be further used to improve educational services.

Application of this study: This research can be used by administration staff and teachers of universities as a guideline in conducting similar surveys.

Novelty/Originality of this study: The novelty of this research lies in the attempt of combining relatively easy in implementation but quite effective in usage rules of conducting student’s survey on higher education quality in one paper.

Published: May 2020

La ciudad de Palma, en Mallorca, representa uno de los principales destinos de playa del Mediterráneo español, por lo que se incorporan nuevos espacios que permiten la expansión turística. Este es el caso del barrio El Molinar, que ha sido objeto de severos procesos de reconversión urbana para crear áreas dedicadas al consumo. El objetivo de este artículo es dar cuenta de un proceso gradual de reconfiguración del espacio, razón por la cual se profundiza en las manifestaciones socioespaciales y en los intentos de remodelación de su puerto marítimo. Como referente teórico y metodológico, se utilizó la tesis de la producción del espacio de Henri Lefebvre. Se concluye que la producción del espacio turístico en El Molinar ha desencadenado diversas alteraciones en el tejido social y en la estructura urbana del barrio, producto de la dualidad Estado-capitales, para incorporarlo en el mercado turístico global como un espacio elitista de consumo.
Agenda dos usuários nas políticas públicas de turismo: uma análise em Curitiba (Brasil)
Authors: Sontag Júnior Dalci , Augusto Gomes Bruno Martins , Vargas Sánchez Alfonso
Published: May 2020

La presente investigación tiene como objetivo analizar la influencia de la agenda de los usuarios en las políticas públicas de turismo a partir de un estudio en Curitiba (Brasil). Para ello, se realizó un análisis cualitativo de las manifestaciones compartidas durante 2016 y 2017 en las páginas de Facebook del Ayuntamiento Municipal de Curitiba, del Instituto Municipal de Turismo de la ciudad y en la Central 156 del municipio. Los resultados indican que la agenda de los usuarios concierne, principalmente, a la oferta de atractivos y equipamientos turísticos y a su enrutamiento, vigilancia sanitaria, medio ambiente y urbanismo. Sin embargo, aunque algunos problemas se resuelvan, hay evidencias de que el foco del órgano público de turismo no es utilizar estas tecnologías como fuente para la formulación de políticas públicas. Se concluye que, en la formulación de políticas públicas, los destinos turísticos, en vez de construir soluciones –a veces distantes de la realidad–, deben dedicar mayor atención a las experiencias cotidianas de los usuarios que contribuyen a solucionar problemas efectivos.

Authors: Szczepańska Elżbieta , Grudowska Elwira
Published: May 2020

Wstęp

Sposób żywienia ma znaczenie nie tylko dla utrzymania dobrego stanu zdrowia, ale również w prewencji wielu chorób. Prawidłowe odżywianie pozwala także utrzymać właściwą masę ciała. Z powodu zwiększenia zainteresowania konsumentów tymi zagadnieniami zaczął rozwijać się nowy sektor rynku żywnościowego, tj. produkty typu light. Celem pracy była ocena częstości ich spożycia oraz analiza zależności pomiędzy częstością konsumpcji a wiekiem, wykształceniem i masą ciała badanych osób.

Materiał i metody

W badaniu brały udział 203 dorosłe osoby, które deklarowały spożywanie produktów typu light. Częstotliwość ich konsumpcji oceniano na podstawie autorskiego kwestionariusza ankiety.

Wyniki

Największy odsetek badanych sięga po produkty mleczne typu light kilka razy w tygodniu (23,2%) lub okazjonalnie (40,4% badanych). Produkty tłuszczowe i słodycze typu light były spożywane okazjonalnie przez odpowiednio 34,5% i 30% badanych osób. Napoje typu light w większości przypadków były konsumowane kilka razy w miesiącu (20,7%) i okazjonalnie (40,4%).

Wnioski

Wśród ankietowanych osób spożycie żywności typu fast food jest rzadkie. Stwierdzono występowanie słabej lub niskiej korelacji pomiędzy częstością spożycia żywności typu light a wiekiem, wykształceniem i masą ciała badanych osób. Konieczne wydaje się prowadzenie edukacji żywieniowej od najmłodszych lat, szczególnie wśród dzieci i młodzieży oraz jej kontynuowanie w populacji osób dorosłych.

Published: May 2020

Pinus halepensis Mill. was introduced into regions with a Mediterranean cli- mate as an ornamental tree, and is now often found in parks and gardens. At pre- sent, Aleppo pine (Pinus halepensis Mill.) forests cover approximately 2,500,000 ha in the Mediterranean Basin, mostly at low altitudes (less than 500 m) and along the coast. It has become naturalized outside cities in North Africa to the extent that it is now listed as an invasive species there. Because of its size (over 15 m in height and 30 cm in diameter), Pinus hale- pensis could be a good potential green resource for structural material in Tunisia. The focus of this study was to assess rot resistance and the physical and mecha- nical properties of reforestation Aleppo pine from the Mediterranean basin. The Pinus halepensis wood samples studied were collected from 6 tree provenances in Tunisia for physical and mechanical characterization and from Morocco for decay and termite resistance tests. Den- sities and shrinkage were determined and mechanical and rot resistance tests performed. Preliminary results showed that Tunisian Pinus halepensis wood has great dimensional stability. Although the compressive strength of Pinus halepen- sis wood is high, its bending strength is rather low for each of the provenances. MOR in bending is lower than in other Tunisian softwood species. Finally, Pinus halepensis sapwood has low resistance to fungi and termites. This timber species could be valuable for furniture and/or as a building material provided that a wood preservation method is applied before it is used.

Published: May 2020

In an effort to increase the strength of mixed asphalt concrete structure ( AC-WC ) in addition to the use of hot asphalt mixture with new specification, the selection of material type used is very important. In addition to asphalt, both coarse and fine aggregates and fillers are one component in a pavement construction that has a large role. Therefore further research is needed on the influence of temperature variation and percentage of filler fly ash to the modulus of r esilien which is good so that it can be applied and able to overcome the damages. In this research is divided into 3 (three) stages namely (1) the selection of materials; (2) the preparation of the specimen; (3) research and data analysis. Asphalt concrete mixed test (AC-WC) showed that Asphalt Optimum (KAO) content with 5.5% asphalt content with VIM value of 3.70%, VMA of 19.00%, Stability of 1,152.93 kg, Flow of 2.78 mm and MQ of 417.39 kg/mm. The result of mixed asphalt concrete (AC-WC) asphalt with filler fly ash test showed that the optimum mixture content was 7% filler content with VIM value 4,21%, VMA 19,21%, Stability 1326.10 kg, Flow of 3.69 mm and MQ of 360.13 kg/mm.

From the equation is known value of coefficient of determination (R ଶ ) = 0,8061 which means success rate in this regression method is 0,8061 (regression model is said good if value R ଶ approach one). In 2016 and 2018 there is a difference in the value of road damage conditions (PCI values). Differences in the value of BOK in 2016 and 2018 on Dr. Soebandi 1 = Rp. 487.69 / km, on the Dr. Soebandi 2 = Rp. -146,7 / km, on Sarangan 1 = Rp. 1327.68 / km, on Sarangan 2 = Rp.-1.99 / km, on Cempaka = Rp. 2827,41 / km, on Tapaksiring = Rp. 1228.02 / km, on Yos Sudarso 1 = Rp. 808,7 / km, on Yos Sudarso 2 = Rp. -2.48 / km, on Wolter Monginsidi 1 = Rp. 544.48 / km, and on Wolter Monginsidi 2 = Rp. -0.23 / km.

Jalan adalah prasarana transportasi umum yang sering digunakan oleh masyarakat. Kondisi jalan yang mengalami kerusakan akan mempengaruhi kecepatan kendaraan yang melintasinya. Dimana kecepatan nantinya akan mempengaruhi biaya operasional kendaraan. Penilaian biaya operasional kendaran menggunakan metode  Pacific Consultant International (PCI). Penelitian dilakukan pada 6 ruas jalan kolektor di Kabupaten Jember yang diperbaiki tahun 2013-2015. Dari hasil analisis biaya operasional kendaraan didapatkan persamaan Y = 0,3315– 65,339x + 6199,1 dimana y adalah nilai BOK dan x adalah nilai PCI. Dari persamaan tersebut diketahui nilai koefisien determinasi ()= 0,8061 yang artinya tingkat keberhasilan dalam metode regresi ini adalah 0,8061 (model regresi dikatakan baik apabila nilai  mendekati satu).

In planning a highway bridge girder using prestressed concrete, it must pay attention to two design categories, namely strength and service. Problems have arisen since the existence of earthquake resistance regulations for road bridges, so planners must calculate the amount of deflection and stress that occurs in the upper structure due to earthquake loads, which must be smaller than the deflection and voltage permits required by regulations. All of that was also greatly influenced by the accuracy of the predicted loss losses for prestressed concrete girders. The purpose of this study was to conduct a study which could be a solution for how to actually treat a good design, for the I-Girder design of prestressed concrete used as a highway bridge girder in the event of inaccurate prediction of loss of pressure during an earthquake, resulting in two design categories strength and service ability can be considered all well. The methodology of this study is to make as a starting point the prestressed concrete I girder whose dimensions are capable of being a highway bridge girder with a span of 30 m to 40 meters with standard loading for loading BM 100. For span bridges that have 100% prediction accuracy, use as a basic benchmark of deflection and stress values that occur for the type of combination of loads that have earthquake loads, then with the same span, varied values of inaccurate predictions lose pre-stress and analyzed deflection and stress values that occur for types of load combinations that have earthquake loads varied earthquake regions 1,2, 3 and 4, for medium soil types. The results of the study show that the greater the percentage of inaccurate prediction of loss of pressure, the greater the deviation ratio of deviations both deflection, upper fiber stress and lower fiber stress occur in the field. Which, if the prediction of losing pre-pressures is smaller than the actual one, then the level of the deviation ratio of the allowable deviation increases as well as vice versa. Also, predicting pre-suppression voltage loss that is located on the side greater than the actual loss of pressure that occurs will be on the part of the party that is harmful to the ability of service and the permissible power, when an earthquake occurs.

Background: Cancer has been one of the most critical health problems during the past decades which require serious consideration, especially in developing countries. Methods: 80 parents of the children with different types of cancers were studied via both questionnaire and person-to-person interview after announcing their informed consent. Results: The highest delay in patients' initial referral was due to the following factors: lack of attention or ignoring the first symptoms, delay in referring to the physician, low economic status and even lack of family support for the patient. In addition, visiting several doctors after the initial diagnosis, uncertainty about the first proposed method, and high cost of treatment can be mentioned as the main causes of delays in the start of treatment. Conclusion: Education plays an important role in identifying the signs of cancer. In addition, proper relationship and cooperation between the health system and physicians as well as provision of adequate information to patients could lead to the long-term cooperation of these patients in continuing their treatment.

Background: Although no specific treatment for COVID 19 has been proven effective yet, some drugs with in vitro potential against SARS-CoV-2 virus have been proposed for clinical use. Hydroxychloroquine has in vitro anti-viral and immunomodulatory activity, but there is no current clinical evidence of its effectiveness on the outcome of the disease. Methods: We enrolled all 18-85 years old inpatients from Central Defense Hospital, Madrid, Spain, who were hospitalised due to COVID-19 and had a definitive outcome (either dead or discharged). We used a statistical survival analysis. Results: We analysed 220 medical records. 166 patients met the inclusion criteria. 48,8 % of patients not treated with HCQ died, versus 22% in the group of hydroxychloroquine (p=0,002). According to clinical picture at admission, hydroxychloroquine increased the mean cumulative survival in all groups from 1,4 to 1,8 times. This difference was statistically significant in the mild group. Conclusions: in a cohort of 166 patients between 18 to 85 years hospitalised with COVID-19, hydroxychloroquine treatment with an initial loading dose of 800mg improved patient survival when admitted in early stages of the disease. There was a non-statistically significant trend towards survival in all groups, which will need to be clarified in subsequent studies.

Coronavirus disease (COVID-19) is a pandemic infectious disease that has a severe risk of spreading rapidly. The quick identification and isolation of the affected persons is the very first step to fight against this virus. In this regard, chest radiology images have been proven to be an effective screening approach of COVID-19 affected patients. A number of AI based solutions have been developed to make the screening of radiological images faster and more accurate in detecting COVID-19. In this study, we are proposing a deep learning based approach using Densenet-121 to effectively detect COVID-19 patients. We incorporated transfer learning technique to leverage the information regarding radiology image learned by another model (CheXNet) which was trained on a huge Radiology dataset of 112,120 images. We trained and tested our model on COVIDx dataset containing 13,800 chest radiography images across 13,725 patients. To check the robustness of our model, we performed both two-class and three-class classifications and achieved 96.49% and 93.71% accuracy respectively. To further validate the consistency of our performance, we performed patient-wise k-fold cross-validation and achieved an average accuracy of 92.91% for three class task. Moreover, we performed an interpretability analysis using Grad-CAM to highlight the most important image regions in making a prediction. Besides ensuring trustworthiness, this explainability can also provide new insights about the critical factors regarding COVID-19. Finally, we developed a website that takes chest radiology images as input and generates probabilities of the presence of COVID-19 or pneumonia and a heatmap highlighting the probable infected regions. Code and models' weights are availabe.

Multidrug resistant extended-spectrum β-lactamase (ESBL)-producing Escherichia coli is considered a serious concern to public health worldwide including Bangladesh, and chicken meat is recognized as an important reservoir of ESBL-Ec dissemination to humans. Therefore, this study aimed to determine the prevalence, and phenotypic and genotypic antimicrobial resistance pattern of ESBL-producing Escherichia coli (ESBL-Ec) in frozen chicken meat. A total of 113 frozen chicken meat samples were purchased from 40 outlets of 9 branded supershops in five megacities in Bangladesh. Isolation and identification of Escherichia coli were done based on cultural, biochemical properties and PCR assay. The resistance pattern was determined by disk diffusion method. ESBL-encoding genes were determined by multiplex PCR. The results showed that 76.1% samples were positive for Escherichia coli, of which 86% were ESBL producers. All the isolates were multidrug-resistant (MDR). Resistance to 9–11 and 12–13 antimicrobial classes was observed in 38.4% and 17.4% isolates, respectively while only 11.6% were resistant to 3–5 classes. The possible extensively drug resistance (pXDR) was found in 2.3% isolates. The high single resistance was observed for oxytetracycline (93%) and amoxicillin (91.9%), followed by ampicillin (89.5%), trimethoprim-sulphamethoxazole and pefloxacin (88.4%), and tetracycline (84.9%). Most importantly, 89.6% of isolates were resistant to carbapenems. All the isolates were positive for blaTEM gene. However, the blaSHV and blaCTX-M-2 genes were identified in two ESBL-non producer isolates. None of the isolates were carried blaCTX-M-1 gene. This study provided evidence of wide dissemination of MDR and existence of pXDR ESBL-Ec in frozen chicken meat in Bangladesh. Our data clearly indicated that frozen chicken meat is, at the present time, the most significant known food source of ESBL-Ec to which peoples are regularly exposed.
