ABSTRACT
Objective: To determine the frequency of urinary tract infections and their causative agents in different age groups in both genders
Materials and Methods: All urine samples received from February 2013 to October 2013 for culture and sensitivity in Baqai Laboratory [a subsidiary of Baqai University Hospital, Nazimabad, Karachi] were processed. Urine samples showing pyuria were inoculated on Cysteine Lactose Electrolyte Deficient [CLED] medium and blood agar and incubated at 37 degree C for 24 hours.Samples showing 10[5] organisms were considered to have significant bacteriuria. Organisms were identified by standard biochemical procedures
Results: Out of 633 samples inoculated, 40% [253] showed significant bacteriuria. Incidence of isolated uropathogens was E.coli [70%], Enterobacter species [9%], Enterococcus species [7.5%], Psudomonas species [5%], Klebsiella species [4%],Acinetobacter species [3.2%], Salmonella species [0.8%], Staph. aureus [less than 1%] and Candida [less than 1%]. Genderwise distribution of patients: Male 36%, Female 64%. Predominent number of female patients was in reproductive age group while greater frequency in males was seen in patients above 55 years of age
Conclusion: There is higher frequency of urinary infections in females in reproductive age groups and more men with urinary infections were aged above 55. E.coli is the prominent causative organism
