| Determinadas linhagens de Escherichia coli comportam-se como patógenos em gatos, causando doenças gastrointestinais e extraintestinais. Neste estudo, foram utilizadas 205 cepas de E. coli isoladas de amostras de fezes provenientes de 19 gatos diarreicos e de 21 gatos não diarreicos, e três amostras de urina provenientes de gatos com infecção do trato urinário (ITU). Essas cepas foram testadas pela técnica de reação em cadeia da polimerase com múltiplos iniciadores para a detecção da presença de genes codificadores de adesinas (pap, sfa e afa), assim como para a detecção dos genes produtores da toxina Shiga-like (stx1 e stx2) e do gene da intimina (eae). Oitenta e dois isolados possuíam genes codificadores de adesinas, dos quais 11 apresentaram o gene pap,... |

| The zoonotic potential to cause human and/or animal infections among multidrug-resistant extraintestinal pathogenic Escherichia coli from avian origin was investigated. Twenty-seven extraintestinal pathogenic E. coli isolates containing the increased survival gene (iss) were obtained from the livers of healthy and diseased poultry carcasses at two slaughterhouses in Salvador, northeastern Brazil. The antimicrobial resistance-susceptibility profiles were conducted with antibiotics of avian and/or human use by the standardized disc-diffusion method. Antimicrobial resistance was higher for levofloxacin (51.8%), amoxicillin/clavulanic acid (70.4%), ampicillin (81.5%), cefalotin (88.8%), tetracycline (100%) and streptomycin (100%). The minimum inhibitory... |

| The study was conducted in twenty-three butcheries in the city of Taquaritinga, State of São Paulo, Brazil, surveyed during a 10 months period. Among two hundred and eighty-seven Escherichia coli strains isolated from samples of ground beef, meat-grinding-machines and the hands of manipulators, five were recognized as extraintestinal pathogenic E. coli (ExPEC), showing virulence factors (P and S fimbriae, hemolysin and aerobactin) and presenting multidrug resistance. Retail-sold food may constitute an important vehicle for the dissemination of ExPEC in communities, giving rise to reasons for concern. |
