14. Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress
RESUMO: Descreve-se os aspectos epidemiológicos, clínicos, patológicos e bacteriológicos da pleuropneumonia por Mannheimia haemolytica em caprinos, após transporte prolongado. Quarenta caprinos transportados da região Nordeste para a região Sul do Brasil morreram durante a viagem ou 2-3 dias após o desembarque. Clinicamente, observou-se dispneia, se

15. Assessment and comparison of bacterial load levels determined by quantitative amplifications in blood culture-positive and negative neonatal sepsis
ABSTRACT Bacterial sepsis remains a major cause of mortality and blood cultures are the gold standard of laboratory diagnosis even though they lack sensitivity in neonates. Culturenegative sepsis, also known as clinical sepsis, has long been considered a diagnosis in neonatal intensive care units because, as well as culture-positive infants, culture-negative

16. Use of molecular techniques for the analysis of the microbiological quality of fish marketed in the municipality of Cuiabá, Mato Grosso, Brazil
ABSTRACT The present study was stimulated by the growing demand for healthy food and the technology available for the detection and identification of microbial organisms in fishery products. Molecular tools were used to identify the bacterial community and detect the presence of pathogenic species in samples of farmed and wild-caught fish. Samples of muscle

17. Screening a bacterium and its effect on the biological degumming of ramie and kenaf
ABSTRACT: Biological degumming is an eco-friendly, efficient, high-quality and low-cost method that has become the leading bast fiber degumming technology. However, bacterial strains with short degumming cycles, high gum removal rates and small fiber damage are few. To screen high quality microbial resources with bast-fiber biological degumming function, soi

18. Elevated Atmospheric CO2 and Drought Affect Soil Microbial Community and Functional Diversity Associated with Glycine max
Abstract Under the background of climate change, the increase of atmospheric CO2 and drought frequency have been considered as significant influencers on the soil microbial communities and the yield and quality of crop. In this study, impacts of increased ambient CO2 and drought on soil microbial structure and functional diversity of a Stagnic Anthrosol were

19. Roles of quorum sensing molecules from Rhizobium etli RT1 in bacterial motility and biofilm formation
ABSTRACT Strain RT1 was isolated from root nodules of Lens culinaris (a lentil) and characterized as Rhizobium etli (a Gram-negative soil-borne bacterium) by 16S rDNA sequencing and phylogenetic analysis. The signaling molecules produced by R. etli (RT1) were detected and identified by high-performance liquid chromatography coupled with mass spectrometry. Th

20. Crescimento, mortalidade e susceptibilidade de ostras Crassostrea spp. à infecção por Perkinsus spp. em cultivo no Nordeste do Brasil
Resumo Crassostrea rhizophorae e C. gasar são cultivadas na região Nordeste. Parasitas Perkinsus infectam bivalves e seus efeitos em ostras de regiões tropicais são pouco compreendidos. Este estudo avaliou o impacto da infecção por Perkinsus em parâmetros de produção de ostras nativas. Ostras foram coletadas bimestralmente durante 7 meses, de julho

21. Assessment of Rice Associated Bacterial Ability to Enhance Rice Seed Germination and Rice Growth Promotion
ABSTRACT The application of beneficial bacteria has recently been used for sustainable agriculture. In current research, 71 bacterial isolates were obtained from rice plant and the rhizosphere soil of different paddy fields in Guilan province, Iran. After primitive investigation, 40 bacteria with typical predominant characteristics were selected. By PCR-RFLP

22. Infestação por carrapatos Argasidae e Ixodidae em pequenos mamíferos silvestres da Estação Experimental Rafael Fernandes, Mossoró/RN
RESUMO: Poucos estudos avaliaram a diversidade de ectoparasitos e a associação deles com seus hospedeiros que ocorrem no bioma Caatinga, Nordeste do Brasil. Considerando-se essa falta de conhecimento, este estudo objetivou identificar e determinar a ocorrência de carrapatos coletados de pequenos mamíferos da Estação Experimental Rafael Fernandes, no Ri

23. Isolation and characterization of a high salt-tolerant and glyphosate-degrading strain of Agrobacterium tumefaciens BZ8
ABSTRACT In this study, a high salt-tolerant and glyphosate-degrading strain named BZ8 was isolated from activated sludge. According to 16S rDNA sequencing methods, morphological, physiological and biochemical analysis, strain BZ8 was identified as Agrobacterium tumefaciens. The growth and glyphosate-degrading capability of A. tumefaciens BZ8 were investigat

24. Isolation and Probiotic Potential of Lactobacillus Salivarius and Pediococcus Pentosaceus in Specific Pathogen Free Chickens
ABSTRACT This study was conducted to isolate Lactobacillus salivarius and Pediococcus pentosaceus strains from cecal content and investigate their probiotic potential in specific pathogen free (SPF) chickens. L. salivarius and P. pentosaceus strains were isolated from the cecal content of SPF chickens and identified by 16s rDNA sequence analysis by BLAST ana
