| Outline of Final Research Achievements |
In this study, I investigated prevalence of antimicrobial resistance and its epidemiological characteristics in various Gram-negative bacteria isolated from companion animals. Resistance to the tested antimicrobials were less prevalent in Proteus mirabilis and Acinetobacter spp.
In contrast, resistances to antimicrobials including beta-lactams were highly prevalent in Klebsiella spp. and Enterobacter spp. isolated from dogs and cats. Most of beta-lactam-resistant isolates in these bacteria had extended-spectrum beta-lactamases.
These findings suggest that prevalence of antimicrobial resistance can differ by bacterial species. Notably, Klebsiella spp. and Enterobacter spp. are regarded as important antimicrobial-resistant bacteria in veterinary medicine and public health.
