| 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 = 134), and humans who claim to have no contact with dogs (n = 44, control), searching for sharing of strains. The strains were assessed for their genetic relatedness by phylogenetic grouping and pulsed-field gel electrophoresis. Multiresistant E. coli strains were isolated from 42 (31.3%) fecal samples from pairs of dogs and owners, totaling 84 isolates, and from 19 (43.1%) control group subjects. The... |

| ABSTRACT Respiratory diseases are common in young horses but little is known about such infections in mule foals. This study aimed to characterize Escherichia coli and Klebsiella sp. isolated from tracheal wash (TW) and fecal samples (FS) of mule foals, with or without cytological evidence of respiratory disease. Strains were analyzed against 13 antimicrobials, for presence of Extended spectrum beta-lactamase (ESBL), and virulence genes. Phylogrouping and Randomic (RAPD)-PCR profiles were used to evaluate their genetic relatedness. E. coli strains from TW and FS showed greatest resistance to tetracycline, while Klebsiella strains were mainly resistant to ampicillin; multidrug resistance and ESBL production were also detected. The blaCTX gene prevailed... |

| This report aimed to study the interference in molecular testing for Ehrlichia canis and Anaplasma platys in blood of 155 dogs from the coastal region of Rio de Janeiro. Five Anaplasmataceae positive samples but negative for E. canis and A. platys, from microfilaremic animals, were chosen for sequencing. These sequences, when compared to Gen et Bank database, showed 88% to 100% similarity with Wolbachia spp. denoting an interference in the detection of DNA from other members of Anaplasmataceae, possibly due to a high concentration of Wolbachia spp. DNA. |
