Objectives: To find out the common pathogenic organisms causing urinary tract infection in patients admitted to the Teaching Hospital, Karapitiya and to review the antibiotic sensitivity pattern of these organisms by analyzing the urine culture results generated by the microbiology laboratory. Design: All the urine culture and antibiotic sensitivity test (ABST)) reports of patients over the age of 12 years generated by the microbiology laboratory between January to May 2008 were collected and analyzed. Setting: The Teaching hospital, Karapitiya. Materials: We have analyzed 1772 urine culture and ABST reports generated between January and May, 2008. Results: This study revealed that coliforms were the predominant pathogenic organisms isolated from the urine samples which were sent for culture and ABST from January to May 2008 and there was emerging resistance to many antibiotics including the commonly used quinolones such as nalidixic acid and norfloxacin.
