Bacteria identification was performed using standard biochemical methods and the API20E enteric identification system. The cultures with a ≥105 CFU/mL bacterial count were defined as positive for UTI. The samples were cultured on blood agar and Eosin Methylene blue agar and incubated overnight at 37☌. Methods: A total of 632 urine samples were collected from hospitalized patients in a teaching hospital. This study investigated the frequency of various beta-lactamases in urine isolates of Proteus mirabilis, Enterobacter cloacae, and Citrobacter freundii in Gorgan, Golestan province.
