The Klebsiella pneumoniae (K. pneumoniae) bacterium is responsible for many opportunistic infections such as sepsis, and a multidrug-resistant (MDR) clone sequence type (ST) 307 has recently begun to spread. The objective of this study was to report the first occurrence of this virulent genotype, which was found in the context of a urinary infection in a domestic feline in Brazil. The K. pneumoniae isolate was identified from the urine of a 6-month-old male crossbreed cat using 16S rRNA sequencing. It was then subjected to antimicrobial susceptibility testing, followed by multilocus sequence typing analysis, and PCR detection of virulence and resistance genes. The antimicrobial susceptibility profile demonstrated that the isolate was MDR and associated with the presence of the colistin resistance gene (mcr-1). Genotyping allowed us to classify the isolate as K. pneumoniae ST307 with the presence of wabG, uge, and entB genes. MDR K. pneumoniae is important in human and veterinary medicine because it causes many types of infections. Clonal propagation of virulent or MDR genotypes such as K. pneumoniae ST307 is a global concern. This report of ST307 isolation from a urine sample in a domestic feline is the first in Brazil.
