Abstract

Simple Summary Urinary tract infections (UTIs) are a significant health concern in dogs and cats and have public health implications, as companion animals can serve as reservoirs for pathogenic and multidrug-resistant (MDR) bacteria. In the study period, the estimated prevalence of UTIs in dogs and cats associated with LUTDs or other illnesses was 26.1%, with true values ranging from 8.0% to 58.9%. Prevalence was higher in dogs than cats and higher in females than in male, and all age groups were affected. Escherichia coli was the predominant causative bacterium, and prevalence remained stable over time.

How strong is the evidence?

Evidence Hub reads this as a meta-analysis, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
