Abstract

The zoonotic potential of multidrug resistant (MDR) bacteria is a worldwide concern and companion animals have been implicated in the spread of resistant bacteria. Therefore, surveillance is important, as there are reports of transmission of these bacteria from dog to men, as well as from men to dog. A 5-year-old mixed-breed male dog was admitted with obstructive struvite urolithiasis relapsing for over 18 months, in Botucatu, in the state of São Paulo, Brazil. The strain, biochemically identified as Staphylococcus spp., was MDR and was treated off-label with vancomycin, which resulted in clinical cure. The strain was molecularly identified as Staphylococcus pseudintermedius and the mecA gene was identified. This is the main gene responsible for methicillin-resistant S. pseudintermedius (MRSP), which is often resistant to multiple antimicrobials. The hypotheses for this clinical case are the transmission from man to animal, since the tutor was an intensivist doctor, or the bacterium itself could be part of the animal’s microbiota and due to other factors, such as stress or obstructive urinary disease, opened a doorway to infection by S. pseudintermedius. Further studies should elucidate the transmission of MDR bacteria between human and pets.
