ABSTRACT
Klebsiella spp. is an important pathogen in humans and animals and due to the indiscriminate use of antibiotics, its prevalence and antibiotic resistance has increased in companion animals. The main goal of this study was to investigate the prevalence and antibiotic resistance of Klebsiella spp. isolated from clinically ill cats and dogs admitted in veterinary clinics in the North of Portugal. A total of 255 clinical specimens were collected and, after isolation, the identification of Klebsiella strains was performed using the BBL Crystal™ identification system and confirmed by PCR-based sequencing with specific primers. Antibiotic resistance profile was determined through the disc diffusion method. Beta-lactam resistance genes were screened through a multiplex PCR assay. Fifty Klebsiella strains were isolated and, 39 were identified as Klebsiella pneumoniae and 11 as Klebsiella oxytoca. Thirty-one were recovered from dogs and 19 from cats. The Klebsiella isolates were recovered mainly from skin wounds, respiratory tract, and from urine. Fifty percent of K. oxytoca and K. pneumoniae isolates revealed to be Multidrug Resistant (MDR) strains, with most of them positive for the presence of blaTEM-like and blaSHV genes. This data shows that MDR Klebsiella are highly disseminated in companion animals and that extended-spectrum beta-lactamases can be easily found among these isolates. This highlights the potential role of dogs and cats as a reservoir of resistant Klebsiella spp. that have the potential to be transmitted to humans.
