Plain-English summary
A study found that urinary tract infections (UTIs) are more common in dogs than in cats, with E. coli being the most frequently identified bacteria. However, many of these bacteria, especially in cats, showed high resistance to common antibiotics used to treat UTIs. This means that treating infections in cats can be more challenging due to the limited effectiveness of standard medications. Understanding these resistance patterns can help veterinarians choose the right treatment for pets suffering from UTIs.

Abstract
BACKGROUND: The increasing emergence of multidrug-resistant bacteria, causing urinary tract infections (UTI) in dogs and cats, represents a great therapeutic challenge and a public health concern. METHODS: Laboratory records of 4943 urinary microbiological diagnosis results and antimicrobial resistance profiles of suspected UTI cases in dogs and cats were analysed from 2016 to 2018 in Spain. RESULTS: This study showed a higher percentage of positive microbiological diagnoses in dogs (42%, 1368/3270) than in cats (27%, 457/1673). Although Escherichia coli was the most frequently isolated bacterium, the frequency of antimicrobial susceptibility of E. coli isolates was lower compared to other bacterial species like Enterococcus spp., Staphylococcus spp., Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter (E. cloacae), and Proteus mirabilis. The antimicrobial susceptibility testing of Gram-positive cocci showed higher levels of resistance in cats to common beta-lactams used for the treatment of complicated UTIs, as well as to fluoroquinolones, aminoglycosides, and carbapenems. Moreover, enterobacteria (E. coli, K. pneumoniae, and P. mirabilis) from cats presented high resistance frequencies to beta-lactams, including third- and fourth-generation cephalosporins and fluoroquinolones. CONCLUSION: This study updates data on the current antimicrobial resistance in UTI bacteria from companion animals in Spain, which may help to guide clinicians for the appropriate use of antimicrobials.
