The primary goal of the study was to determine the prevalence and various bacterial risks of lower urinary tract infections (UTI) in diseased and seemingly healthy pet animals with and without urine retention whether they were catheterized or not. The bacterial isolates were in vitro tested for their antibiotic resistance and antibiotic resistance genes were investigated. Between October 2020 and January 2022, 128 urine samples were randomly collected from pets recruited to veterinary hospitals and clinics in Cairo and Giza. Samples were cultivated for bacteriological isolation. Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Klebsiella spp. were found to be the most common bacterial causes of urinary tract infections in pets, with prevalence rates of 32.9%, 28%, and 19.5%, respectively followed by Proteus mirabilis (P. mirabilis) and Pseudomonas aeruginosa (P. aeruginosa) with incidences of 18.2% and 1.2%, respectively. Based on bacterial types and their virulence genes, antibiotic resistance and multi-drug resistance (MDR) behaviour varied. Epidemiology, diagnosis, and control of the urinary tract infection would benefit from the identification and characterization of isolated bacterial species.
