Abstract Most known plasmids are identified by conferring virulence or antimicrobial resistance phenotypes and such characteristics aid in the success of the dispersion of different plasmid types between bacteria from different sources. This study aimed to perform the subtyping of the plasmid-mediated quinolone resistance, detected in Salmonella spp. A total of 34 Salmonella strains non-susceptible to ciprofloxacin were evaluated. Strains were selected based on the presence of PMQR determined by...

Case presentation We present a case report of a woman, concurrently colonized by polymyxin-resistant E. coli and K. pneumoniae. A Brazilian female patient, in her mid-fifties, was hospitalized with schistosomiasis. During hospitalization, polymyxin-resistant E. coli and K. pneumoniae were isolated from surveillance cultures.

Exotic psittacine birds have been implicated as reservoir of diarrheagenic Escherichia coli (E. coli), including enteropathogenic E. coli (EPEC) and Shiga-toxin producing E. coli (STEC). Here, we present a genotypic and phenotypic characterization of typical EPEC/STEC hybrid strains isolated from exotic psittacine birds. The strains were positive for eae, bfpA, and stx2f genes, belonged to serotype O137:H6 and ST2678. Two strains were subject to whole genome sequencing, confirming the presence o...

Abstract We surveyed healthy captive cockatiels ( Nymphicus hollandicus ) for Escherichia coli and Salmonella spp. Cloacal swabs were collected from 94 cockatiels kept in commercial breeders, private residencies and pet shops in the cities of Sao Paulo/SP and Niteroi/RJ (Brazil). Three strains of E. coli from each individual were tested for the presence of ExPEC-, APEC- and DEC-related genes. We evaluated the bla TEM , bla SHV , bla OXA , bla CMY , bla CTX-M , tetA , tetB , aadA , aphA , strAB ,...

AbstractBackground: Edwardsiella tarda infections are frequent causes of severe outbreaks in the fish farming industry besides representing possible zoonotic risks. However, naturally occurring outbreaks that affect various species besides fishes are seldom described.Aim: To report an outbreak of acute mortality caused by E. tarda affecting multiple species that inhabited a natural pond in the state of Sao Paulo, Brazil.Materials and methods: Three adult tilapias, three Mallard ducks and one Sno...

Abstract The presence of free-ranging urban birds is a risk factor for transmitting pathogens to captive animals and humans alike, including Salmonella spp. and diarrheagenic Escherichia coli. Cloacal swabs from 156 synanthropic Great egrets (Ardea alba) and feral pigeons (Columba livia domestica) that inhabit the surroundings of an urban zoo were processed for the identification of Salmonella spp. and diarrheagenic E. coli pathotypes. Bacterial species identification and genotypic characterizat...

More than 80 species of birds belonged to the family Psittacidae in Brazil, including parrots, macaws and parakeets. The maintenance of these birds in Zoos may help the conservation of the species, but the captivity can favor intestinal colonization by enterobacteria. The aim of this study was to identify the presence of Klebsiella spp. in the fecal samples of captive parrots. Thirty - four fecal samples were analyzed. The results showed that 11 (32.35%) were positive for Klebsiella spp., with i...
