Introduction: The current rise in polyresistant bacterial strains is due to self-medication, failure to comply the treatment, incorrect prescription of antibiotics by the physician, and even the abuse of these in agriculture industries. In this research, we suggest another possible source. Humans, being in coexistence with dogs and in contact with their saliva, could have been exposed to polyresistant microorganisms that are potential pathogens to. Identify, isolate and analyze these possible microorganisms were the main objectives of this study. Materials and methods: Oral samples (n=28) from domestic dogs were taken and cultured. Bacterial colonies (n = 160) were obtained and subjected to identification and antimicrobial sensitivity tests. Results: From 160 isolated colonies, the most prevalent species was Staphylococcus haemolyticus. Other bacteria such as Enterococcus faecium, Escherichia coli, Proteus mirabilis, and Pseudomonas aeruginosa were also found in a lesser proportion. There was an increased resistance of the bacteria against cell wall synthesis antibiotics. The resistance towards vancomycin was the highest, followed by cefalotin and cefixime. In contrast, all bacteria were sensible to imipenem. Conclusion: The resistance observed against protein synthesis inhibitors showed a high resistance towards erythromycin and clarithromycin but a high sensibility to amikacin and gentamicin. In this study several human pathogens that are the cause of infectious diseases were identified in the oral microbiota of dogs. Furthermore, another risk of polyresistant bacteria transmission is proposed with the determination of each bacterial resistance. |
