The aim of this study was to serotype and determine the antibacterial sensitivity profile of Salmonella spp strains isolated from taricaya turtles (Podocnemis unifilis) from the Huachipa Zoological Park (n = 30). Lima, and the Natural Park of Pucallpa (n = 43), Ucayali, located in the coastal and jungle region of Peru, respectively. A total of 73 samples of cloacal swabs were obtained that were inoculated in Stuart bacterial transport media, enrichment media (tetrathionate broth) and selective media (XLD agar and Salmonella-Shigella), finding typical lactose-negative colonies of Salmonella, which were verified by biochemical tests standard (4.11%, 3/73). The results of the serological typing using the Kauffmann-White scheme showed that two of the three strains corresponded to Salmonella Javiana (O9,12: I, Z28: H5) and the other as not determined. The three positive samples were from juve...

The aim of this study was to determine the phylogenetic groups of Escherichia coli isolated from alpacas with diarrhoea. The presence of E. coli was determined in 150 samples of diarrheal faeces collected from young alpacas from the central highlands of Peru, and the distribution of phylogenetic groups was determined by the Clermont method. E. coli was present in 79.3% (119/150) of animals with diarrhoea. The strains were classified into phylogenetic groups A, B1, B2 and D, which showed a frequency of 13.5% (16/119), 65.5% (78/119), 1.68% (2/119) and 19.33% (11/23), respectively. Moreover, 21% (25/119) of isolated strains of E. coli belonged to phylogenetic groups B2 and D, mainly extraintestinal pathogenic strains, and 79% (94/119) to groups B1 and A, which are mainly commensal strains.
