Abstract 

Background, Urinary tract infection is one of the common infections in the Libya community.
Distribution and susceptibility of causing pathogens change rendering to period and place. UTI are
difficult infections, because UTI sick of children, men and pregnant women.
The aims of this study are determine the relationship between UTI and gender and age by determine
the prevalence of UTI in children, men and women, and observe the more common pathogenic bacteria
in UTI. Also, to determine the antimicrobial susceptibility of pathogenic bacteria.
Study area, The data of the present article had taken from the recorders of medical laboratory of urine
cultures and sensitivity of Zawia's hospital, Zawia city in Libya. Study target, UTI patient's children,
women and men.
This study detected that bacteria were sensitive to some antibiotics and resist to the others; all types of
important pathogenic bacteria were sensitive to both antibiotics Cip and AR. In addition to last
antibiotics E. coli, K. pneumonia, P. aeruginosa and S. marcescens were also sensitive to CTX, Amc,
SXT, Ipm, and Gm. In opposite to theses pathogenic bacteria, some pathogenic bacteria appearance
resistant to some antibiotics as fallow; K. pneumonia, K. oxytoca, E. cloacae, S. marcescens and C. koseri
appearance resistant to Amp.
