title: Sanitary quality and prevalence of serovars of Salmonella in handmade and inspected fresh pork sausages sold in western Paraná, Brazil

description: The manufacture of fresh pork sausage requires a series of manipulation steps, which increases the chances of contamination by several species of micro-organisms, be them pathogenic or deteriorating. This may compromise the microbiological quality of the final product and transmit diseases with consumption. In the period from April to September 2009, the microbiological quality of 40 samples of fresh handmade sausage inspected by the Inspection State and Federal Service in the cities of Cascavel and Toledo (PR) was assessed, through the quantification of thermotolerant coliforms, Staphylococcus spp., viable facultative and strict mesophilic aerobic bacteria, Salmonella spp., Campylobacterspp., Bacillus cereus, Clostridium sulfite reducers, molds and yeasts. The results revealed that 55% of the analyzed samples of fresh handmade and inspected sausages were not in accordance with the parameters established by Resolution RDC Nº 12, of January 2nd, 2001, from ANVISA, in at least one of the studied groups of micro-organisms. Therefore, we can say the sausages sold in western regions, may present a risk to public health.

title: Antibiosis and non preference for the oviposition of Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) in common bean genotypes

description: The common bean Phaseolus vulgaris L. constitutes an important source of protein and income for many countries, including Brazil. Different factors contribute with the reduction in production, including pest insects, especially Bemisia tabaci (Genn.) biotype B. This study aimed to identify common bean genotypes resistant to B. tabaci biotype B and the types of resistance involved. Therefore, two experiments were developed in a greenhouse and laboratory, evaluating 11 common bean genotypes. To test the free-choice experimental design, the randomized block design was adopted, and the completely randomized one was selected for the no-choice tests and antibiosis, with six replications for each test. The following variables were evaluated: incubation period of eggs; nymphal; egg to adult; viability of egg to adult and adult longevity. The IAC-Harmony prolonged the nymphal and egg to adult periods of B. tabaci biotype B. The genotypes were also tested by the whitefly oviposition in free and no choice tests.

title: Evaluation of different culture media and enrichment in orange juice upon the growth of Alicyclobacillusspp.

description: Bacteria of the genus Alicyiclobacillus spp. form spores and develop in acid media, leading to the spoilage of citrus juices. Brazil is the largest exporter of orange juice concentrate, and yet, it has been extensively studied due to changes in taste and smell. Several investigations have reported different culture media used to detect and enumerate Alicyiclobacillus spp. The objective of the present study was to evaluate the recovery of Alicyiclobacillus spp. spores grown in ALI, BAT, K agar and YSG media using the methodology suggested by ABECitrus. Five inocula were used, two from reference strains and three from pasteurized concentrated orange juice. Cell recovery after the enrichment in reconstituted orange juice was also analyzed. An initial population of 6 log CFU/mL was inoculated. ALI, BAT and YSG media were able to recover the initial population of all different inocula, with no significant differences between the results. When compared to BAT, however, the preparation of ALI and YSG media was simpler and had more advantages. The recovery with K agar medium was lower than the other media for all the tested inocula, with significant differences found for Alicyclobacillus acidocaldarius0298T (3.66 log CFU/mL) and Alicyclobacillus pomorum-like CBMAI 0278 (4.11 log CFU/mL).

title: Selectivity of insecticides to some natural enemies in the culture of cotton

description: The aim of this work was study the selectivity of insecticides in favor of natural enemies in cotton (Gossypium hirsutum latifolium Hurtch Lr), DeltaOpal cultivar, in the city of Malhada (BA), and to know the associated beneficial fauna. The study was conducted at the agricultural year of 2010/2011. The design was conducted in randomized blocks with six treatments and four replications. The treatments were: (1) Fipronil 200 SC (0.38 L.ha-1); (2) Alphacypermethrin 100 SC (0.30 L.ha-1), (3) Lufenuron 50 EC (0.30 L.ha-1), (4) Imidacloprid 200 SC (0.30 L.ha-1), (5) Methyl parathion 600 EC (1.00 L.ha-1), and (6) control (water). The product was applied 80 days after emergence, and the evaluations were performed one day before application and 1, 7 and 14 days after application (DAA). The samples were taken using the sampling method beating cloth and Moericke traps. Natural enemies were brought to the laboratory for sorting, counting and identification by family. The toxicity of the products ranged according to the group of natural enemies. Imidacloprid is selective to the spiders and insecticides are moderately toxic (Methyl Parathion and Alphacypermethrin: 1 and 14th DAA; Lufenuron: 14th DAA) or toxic (Fipronil and Alphacypermethrin: 7thDAA). Fipronil (1 DAA), Alphacypermethrin (7th DAA) and Methyl Parathion (14th DAA) are moderately toxic to adult ladybirds. The analyzed insecticides are toxic to the larvae of ladybirds, with more impact until seven days after the application, with the exception of Methyl Parathion classified, as innocuous until this period. The occurrence of 13 families of spiders and 18 families of parasitic Hymenoptera is registered in cotton agroecosystems in the region of Malhada, in the state of Bahia.

title: Evaluation of leptospirosis control through vaccination in a cattle dairy farm in the state of Piauí

description: For this study, we collected sera from 255 cows and 2 bulls in the period from 2004 to 2009, with six-month intervals, a dairy cattle farm in the municipality of Buriti dos Lopes, in the state of Piauí. By the microscopic agglutination test (MAT), we found the following serovars of leptospira: Hardjobovis, Hardjoprajitno (Norma), Hardjoprajitno (WHO). For the control of leptospirosis, a vaccine containing the same serovars that were found infecting the herd was tested. The results showed that in dairy cattle in the basin of Parnaiba, state of Piauí, leptospirosis occurs with a predominance of serovar Hardjobovis. The use of a vaccine containing the most prevalent serovars in the herd applied every six months during the course of five years was important to reduce antibody titers and reproductive problems in cattle.

title: Immobilization of filamentous fungi with potential for agribusiness

description: Cellular immobilization represents an alternative for the bioprocess conduction, in which the cells are kept in a matrix and can be used over long periods. The objective of this work was to test a new fungi immobilization methodology with reduced cost to evaluate the viability of these fungi when submitted to the new encapsulation method, and to determine the ideal temperature to store the immobilized fungi. The mycelium of the fungi Aspergillus niger, Cladosporium cladosporioidesand Penicillium solitum were mixed with 15 g of titrated rice and 3 g of sodium alginate, which was dripped in a 0.25 M calcium chloride solution for the formation of pellets. After drying in an oven at 26ºC, the granules were stored at three temperatures: room, refrigerator and freezer. The platings were carried out every 15 days in culture medium. The evaluations of the colony size and sporulation were carried out 7, 14 and 12 days after plating, for 195 days for A. niger, 225 days for C. cladosporioides,and 210 days for P. solitum.Storage temperature did not affect the mycelial development of A. niger and P. solitum. However, sporulation was reduced for the granules stored in the freezer. The mycelial development of C. cladosporioides was influenced by temperature. The granules conserved at room temperature had lower viability than those stored in the refrigerator and freezer. In the Scanning Electronic Microscopy analysis, it was observed that the immobilization is a safe method in which the fungus mycelium remains inside the granule, facilitating transport, storage and application of micro-organisms.

title: Occurrence of Escherichia coli O157:H7 and O26 sorbitol negative in a cattle slaughterhouse and susceptibility to antimicrobials

description: Cattle beef could be a way of transmitting Escherichia coli O157: H7 and non-O157 to humans if they consume undercooked meat, being responsible for causing severe diseases such as hemolytic uremic syndrome. Bacterial resistance has become worrying concerning the efficacy in the treatment of diseases, and because of these aspects, the objective of this study was to verify the occurrence of E. coli O157: H7 and non-O157 in the stages of cattle slaughter and to evaluate the susceptibility of these bacteria against antimicrobial action. We collected from a cattle slaughterhouse 21 samples from manipulators' hands, 21 from knives and 300 from 50 animals in six points of the flowchart. The isolation was performed using the CT-SMAC agar and characterization of serotypes by PCR. There was higher occurrence of E. coli O157: H7 (12.0%) in animals and lower prevalence of E. coli O26 (8.0%) and O113 (2.0%). E. coli O26 was present in 9.52% of the knives. The presence of E. coli non-O157 sorbitol negative was an unexpected fact due to the method of isolation. All E. coli O157: H7 isolates were sensitive to tetracycline, cefepime, cefoxitin, ciprofloxacin and sulphazotrim, and 78.85% of them were resistant to cephalothin and 34.61% to ampicillin. All E. coli O26 were sensitive to cefepime, cefoxitin and sulphazotrim, and 88.23% were resistant to tetracycline and cephalothin and 82.35% to ampicillin. The antimicrobial multiresistance was observed in both serotypes. It should be, therefore, a criteria for using antimicrobial in treatments to avoid become a public health concern.

title: Biology and fertility life table of Diabrotica speciosa (Col.: Chrysomelidae) in natural diet

description: Corn rootworm Diabrotica speciosa is an important pest in several crops. The aim of this work was to study the biology of adult D. speciosa and build a fertility life table in the natural diet based on beans, and beans, sliced carrots and honey solution at 10%. The following parameters were: duration of pre-oviposition, oviposition and post-oviposition, total fertility, adult longevity and egg viability. For the fertility life table parameters, the following were determined: generation interval (T), net reproductive rate (Ro), intrinsic rate of increase (rm) and finite rate of increase (λ). From the results obtained, it can be observed that there was an influence of food offered to adults for the duration of pre-oviposition and oviposition, and also in total fertility and viability of eggs. Adult longevity was influenced by diet consisting of bean leaflets. Among the treatments, a diet consisting of beans, carrot and honey provided higher significant longevity of males compared to those fed with beans. The results in the fertility table indicated that the reproductive potential of D. speciosa significantly increases in two successive generations when females are fed on beans, carrots and honey, showing there is improved mass rearing for this insect under laboratory conditions.
