title: Helminth metacommunity structure of wild rodents in a preserved area of the Atlantic Forest, Southeast Brazil

description: Abstract The helminth fauna and metacommunity structure of eight sympatric sigmodontine rodents were investigated at the Serra dos Órgãos National Park, an Atlantic Forest reserve located in the State of Rio de Janeiro, southeast Brazil. Rodents of the species Abrawayaomys ruschii, Akodon montensis, Blarinomys breviceps , Delomys dorsalis, Oligoryzomys flavescens, Oligoryzomys nigripes, Oxymycterus quaestor and Thaptomys nigrita were found infected with helminths. Akodon montensis presented the highest total helminth species richness, with six different species of helminths. The nematode Stilestrongylus lanfrediae was the most abundant and prevalent helminth species observed. The host-parasite network analysis showed little interactions among host species. Akodon montensis seems to act as a keystone-species in the rodent community. This species shared the nematodes Stilestrongylus aculeata with A. ruschii and Protospirura numidica criceticola with T. nigrita, and the cestode Rodentolepis akodontis with D. dorsalis. The congeners host species O. flavescens and O. nigripes shared the nematodes Guerrerostrongylus zetta and S. lanfrediae. The rodents B. breviceps and O. quaestor did not share any helminths with other hosts. The helminth metacommunity showed a random pattern on both infracommunity and component community levels, indicating different responses by each helminth species to the environmental gradient.

title: Micro RNA 146a-5p expression in Kidney transplant recipients with delayed graft function

description: ABSTRACT Introduction: The development of novel non-invasive biomarkers of kidney graft dysfunction, especially in the course of the delayed graft function period would be an important step forward in the clinical practice of kidney transplantation. Methods: We evaluated by RT-PCR the expression of miRNA-146 to -5p ribonucleic micro-acids (miRNAs) in the peripheral blood and renal tissue obtained from kidney transplant recipients who underwent a surveillance graft biopsy during the period of delayed graft function. Results: In biopsy samples, the expression of miR-146a-5p was significantly increased in the group of patients with delayed graft function (DGF) (n = 33) versus stables patients (STA) (n = 13) and patients with acute rejection (AR) (n = 9) (p = 0.008). In peripheral blood samples, a non-significant increase of miR-146a-5p expression was found in the DGF group versus STA and AR groups (p = 0.083). No significant correlation was found between levels of expression in biopsy and plasma. ROC curve analysis revealed an AUC of 0.75 (95% CI: 0.62-0.88) for the renal tissue expression and 0.67 (95% CI 0.52-0.81) for the peripheral blood expression. Conclusion: We conclude that miR-146a-5p expression has a distinct pattern in the renal tissue and perhaps in the peripheral blood in the setting of DGF. Further refinements and strategies for studies should be developed in the field of non-invasive molecular diagnosis of kidney graft dysfunction.

title: Association between religiosity and happiness in patients with chronic kidney disease on hemodialysis

description: Abstract Objectives: Religiosity/spirituality (R/S) seems to be a relevant factor in chronic diseases adaptation, but there is a lack of studies involving chronic kidney disease (CKD). This study aimed to investigate the association between R/S and happiness among CKD patients on hemodialysis and whether Sense of Coherence (SC) mediates this possible association. Methods: This was a cross-sectional study in two renal replacement therapy centers in Brazil, involving 161 adults on hemodialysis. Linear regressions were performed to evaluate the association between R/S (predicting variable measured with Duke Religious Index - DUREL) and happiness (outcome variable), adjusted for sociodemographic, clinical, and some laboratory variables. Later, SC was added to the model to test the possible mediating effect. Results: Most patients (91.20%) reported some religious affiliation. Private Religiosity (PR) (β = 0.53; 95% CI = 0.01 a 1.06), Intrinsic Religiosity (IR) (β = 0.48; 95% CI = 0.18 a 0.79), and SC (β = 0.11; 95% CI = -0.09 a 0.15) correlated with higher levels of happiness, controlling for clinical and sociodemographic variables. When SC was included in the model, IR (β = 0.34; 95% CI = 0.07 to 0.60) and SC (β = 0.11; 95% CI = 0.08 to 0.14) remained significantly. No clinical or sociodemographic variable correlated with happiness. Conclusions: Patients on hemodialysis showed high levels of R/S, which correlated with higher happiness levels. Clinical and sociodemographic variables were not correlated with patients' happiness. Psychosocial variables such as R/S and SC are potential key targets for interventions to promote better survival quality among CKD patients.

title: Nematode resistance to five anthelmintic classes in naturally infected sheep herds in Northeastern Brazil

description: Abstract This study aimed to evaluate the occurrence of nematode resistance to anthelmintics on sheep herds from the semi-arid region of Paraíba, Northeastern Brazil. Fecal Egg Count Reduction Test (FECRT) was carried out on 20 properties. In each herd, 30 animals were divided into five groups containing six animals each: group I, treated with albendazole 10%, 4 mg/kg; group II, ivermectin 0.08%, 0.2 mg/kg; group III, closantel 10%, 10 mg/kg; group IV, levamisole hydrochloride 5%, 5 mg/kg; and group V, monepantel 2.5%, 2.5 mg/kg. All treatments were administered orally as a single dose. Fecal samples were collected on days zero and 10 after treatment, to perform FECRT and coprocultures. Multiresistance was observed in all the properties; 95% had high resistance to albendazole, 85% to ivermectin, 80% to closantel, 40% to levamisole, and 45% to monepantel. On property 15, where monepantel was ineffective, a second FECRT for this anthelmintic was carried out 4 months after the first, resulting in 75% efficacy. Immediately after the FECRT result, two ewes were euthanized and necropsied, and Haemonchus contortus, Trichostrongylus axei, Trichostrongylus colubriformis, Oesophagostomum columbianum, and Trichuris ovis were recovered. It was concluded that the resistance of sheep gastrointestinal nematodes to antthelmintic, including monepantel, is high.

title: Eimeria spp. (Apicomplexa: Eimeriidae) of marsupials (Mammalia: Didelphimorphia) in southern Bahia, Brazil

description: Abstract The occurrence of Eimeria Schneider, 1875 in mammals of the order Didelphimorphia indicates the infection-predisposition of these animals, which in turn is mainly determined for their eating habits. The objective of this work was to evaluate the parasitism of Eimeria spp. in marsupials of the Atlantic Forest of the southern region of Bahia. Fecal samples were collected from marsupials captured in the regions of Ilhéus, Una, Belmonte and Mascote, with traps of the Sherman model (23 × 8 × 9 cm), Tomahawk (50 × 17 × 17 cm) and pitfall and analyzed by Sheather's modified centrifugal-flotation method. Oocysts were identified by microscopical evaluation of their morphology and morphometry. Didelphis aurita Wied-Neuwied, 1826, Gracilinanus agilis Burmeister, 1854, Monodelphis americana Müller, 1776, Marmosa demerarae O. Thomas, 1905 and Marmosa murina Linnaeus, 1758 were parasitized by Eimeria philanderi Lainson & Shaw, 1989 and Eimeria gambai Carini, 1938. Mixed parasitism for these two coccidia was observed in two of the 56 marsupials sampled. In conclusion, this work registers new hosts for E. philanderi and E. gambai, as well as the state of Bahia as a new distribution site for these coccidia.

title: Prevalence and associated factors with Neospora caninum infection in female water buffaloes (Bubalus bubalis) from Pernambuco, Brazil

description: Abstract Neosporosis is one of the major parasitic diseases that causes reproductive problems, making it a limitation for optimal efficiency in livestock. The aim of the present study was to conduct a seroepidemiological survey for bubaline neosporosis and to analyse associated factors associated with N. caninum infection in female water buffaloes in the State of Pernambuco, northeast Brazil. The prevalence of N. caninum infection in the bubaline herds examined was 35.4% (122/345; 95% CI: 30.4%-40.7%), at least 1 Neospora-positive animal was found in each farm. Associated factors for N. caninum infection identified in this study were exclusive pasture feeding (OR: 5.91, p &lt;0.001) and purchase of animals of free fair and from reputable sellers (OR: 1.85; p =0.045). In this survey, we document the occurrence of neosporosis in female water buffaloes. Associated factors should be controlled in order to reduce the risk of N. caninum infection in these herds.

title: WOOD UTILIZATION OF Eucalyptus grandis IN STRUCTURAL ELEMENTS: DENSITIES AND MECHANICAL PROPERTIES

description: ABSTRACT Over the years, the species of eucalyptus has become a multipurpose raw material. In addition, the most relevant aspect of the use for various purposes is related to the production of a high quality wood, coming from short duration plantations, which is fundamental to the current demand of the industries. However, its use in civil construction has not yet reached a level of importance, due to the low knowledge of many of its resistance properties and the consequent popular fear in the use of reforestation woods, in particular the Eucalyptus grandis. This research investigated its main mechanical properties, aiming to reinforce its constructive applications in wood structures. For this, two physical properties and fourteen mechanical properties, in two different moisture conditions of the samples were evaluated, according to the norm NBR 7190 (1997). In the first moisture content, the samples were stabilized at 30%, while the second level considered the content of 12%. It was obtained 3580 determinations for the sixteen properties. From the 14 mechanical properties, only 7 had significant increases with the moisture reduction (30% to 12%), consisting of the rupture modulus in the parallel and normal compressions, normal traction and static bending; modulus of elasticity in normal compression and static bending and in shear strength.

title: Occurrence of Dioctophyme renale larvae (Goeze, 1782) (Nematoda: Enoplida) in a new host from southern Brazil

description: Abstract Dioctophymatosis is caused by the giant kidney worm Dioctophyme renale which occurs in dogs, cats, and wild mammals. In Brazil, the disease has been diagnosed in dogs from several states around the country. In the present study, the occurrence of D. renale larvae in snakes from southern of Brazil is reported. Three specimens of Philodryas patagoniensis (Serpentes: Dipsadidae) (common names in Brazil: “parelheira”, “papa-pinto”) roadkill in the county of Capão do Leão, State of Rio Grande do Sul, southern Brazil, were necropsied. Two third-stage larvae of D. renale were found in the coelomic cavity of P. patagoniensis. This study reveals a new host for D. renale larvae in the southern region of the State of Rio Grande do Sul, Brazil. This particular geographic area of the country has stood out as several cases of D. renale infection have been reported in a number of vertebrates from this region including domestic dogs and cats and wild animals such as carnivores, fish, and freshwater turtles.

title: Detection of a putative novel genotype of Ehrlichia sp. from opossums (Didelphis aurita) from Brazil

description: Abstract Erlichiosis affects humans and animals worldwide. Its distribution and prevalence depends on the presence of tick vectors and hosts in one geographic area. The aim of the present study was to investigate the occurrence of Ehrlichia spp. and Anaplasma spp. in opossums (Didelphis sp.) from the State of Rio de Janeiro, southeast Brazil. Blood samples from 37 animals were tested for these two pathogens using molecular methods. One animal (2.7%) was positive for Ehrlichia sp. by 16S rRNA-based nested PCR. In a phylogenetic analysis based on the 16S rRNA gene using the maximum likelihood method and the GTRGAMMA+I evolutionary model, we detected a novel Ehrlichia sp. genotype closely related to genotypes of E. canis previously reported in dogs from Brazil. To the authors’ knowledge, this is the first molecular detection of Ehrlichia sp. in opossums from this State in the southeastern region of the country.
