13. DNA Profiles of Salmonella Spp. Isolated from Chicken Products and From Broiler and Human Feces
ABSTRACT Salmonella species have been isolated from various kinds of food and are accountable for outbreaks of foodborne diseases in humans. This study aimed at identifying the similarities between the DNA profiles of Salmonella isolated from chicken feces, chicken products, and human feces in southern Brazil. Six hundred samples were collected (200 from chi

16. Semisolid liver infusion tryptose supplemented with human urine allows growth and isolation of Trypanosoma cruzi and Trypanosoma rangeli clonal lineages
Abstract: INTRODUCTION This work shows that 3% (v/v) human urine (HU) in semisolid Liver Infusion Tryptose (SSL) medium favors the growth of Trypanosoma cruzi and T. rangeli. METHODS Parasites were plated as individual or mixed strains on SSL medium and on SSL medium with 3% human urine (SSL-HU). Isolate DNA was analyzed using polymerase chain reaction (

17. Coagulase-negative staphylococci in Southern Brazil: looking toward its high diversity
Abstract: INTRODUCTION: Coagulase-negative staphylococci (CoNS) are the most prevalent pathogens in nosocomial infections and may serve as a reservoir of mobile genetic elements such as the staphylococcal cassette chromosome mec (SCCmec) encoding methicillin resistance. Molecular characterization of SCCmec types combined with advanced molecular typing tech

18. Descrição de Staphylococcus pseudintermedius meticilina-resistentes de piodermite canina no estado de Minas Gerais, Brasil
Staphylococcus pseudintermedius meticilina-resistente (MRSP) é de preocupação mundial na medicina veterinária. A identificação de cepas resistentes é necessária a um tratamento adequado e à prevenção da sua propagação entre os animais. O objetivo do estudo foi identificar S. pseudintermedius isolados de piodermite canina e avaliar o perfil de re

19. Resistance patterns, ESBL genes, and genetic relatedness of Escherichia coli from dogs and owners
Abstract Antimicrobial resistance in Escherichia coli isolated from pet dogs can be considered a potential threat of infection for the human population. Our objective was to characterize the resistance pattern, extended spectrum beta-lactamase production and genetic relatedness of multiresistant E. coli strains isolated from dogs (n = 134), their owners (n =

20. Co-transmission of Rahnella aquatilis between hospitalized patients
ABSTRACT Rahnella aquatilis is an environmental Gram-negative bacillus that is rarely reported as human pathogen, being mainly associated with infections in immunocompromised patients. Herein we describe two cases ofR. aquatilis isolates recovered from endotracheal aspirate cultures of different patients in a tertiary hospital located in the city of São Pau

22. Antimicrobial resistance and genetic diversity of Escherichia coli isolated from humans and foods
Antibiotic resistance has increased in recent years, raising the concern of public health authorities. We conducted a study of Escherichia coli isolates obtained from human and food samples to assess the prevalence of antimicrobial resistance and to determine the genotype and clonal relationship of 84 E. coli isolates (48 from humans and 36 from foods). An a

24. Production of metallo-β-lactamase among Pseudomonas aeruginosa strains isolated in the State of Sergipe, Brazil
INTRODUCTION: Acquired production of metallo-β-lactamases is an important mechanism of resistance in Pseudomonas aeruginosa. The objective of this study was to investigate the production of metallo-β-lactamase and the genetic diversity among ceftazidime-resistant P. aeruginosa isolates from State of Sergipe, Brazil. METHODS: Metallo-β-lactamase was inves
