The present study aimed to determine the prevalence of Proteus species in various clinical samples and to evaluate their antibiotic susceptibility patterns. A total of 2400 clinical specimens were analyzed over a six-month study period. All samples underwent direct microscopy and culture for the isolation and identification of Proteus species. Out of the total samples, 67 isolates of Proteus species were identified, of which Proteus vulgaris accounted for 38 cases (56.72%) and Proteus mirabilis for 29 cases (43.28%). The majority of isolates were obtained from pus and urine samples. Antibiotic susceptibility testing by the Kirby–Bauer disc diffusion method revealed high sensitivity to piperacillin-tazobactam (89.55%), amikacin (65.67%), and ceftriaxone (61.19%). In urine isolates, higher sensitivities were observed with fosfomycin (82.76%) and nitrofurantoin (65.67%). High resistance rates were recorded for colistin (100%), levofloxacin (44.77%), and imipenem (41.79%). Given the rising antimicrobial resistance among Proteus species, their increasing prevalence may pose a significant public health concern.
