Summary: | Aim: We studied the causative microorganisms and antibiotic susceptibility of urinary tract infections (UTI) for both male and female in Nagaland, North-Eastern India. Materials and Methods: This is a retrospective study done at Christian Institute of Health Sciences and Research, Dimapur, where urinary samples received for culture and sensitivity in the laboratory from January 2012 to June 2013 were included. Organisms were identified by doing standard culture method, and antibiotic sensitivity was done by Kirby-Bauer Disc diffusion method from mid-stream clean catch urine sample. Results: A total of 1789 samples were analyzed in this study, where 502 (28.1%) showed significant growth, 330 (18.4%) showed insignificant growth, and the rest 957 (53.5%) showed no growth. The most commonly isolated bacterium was Escherichia coli both in an outpatient department (31%) and in-patient department (38%) patients followed by Klebsiella pneumonia, Pseudomonas sp., Enterococcus, Staphylococcus aureus, Candida, and Proteus. Analysis of the samples showed that UTI was more common in females (60%) as compared to males (40%). It was also observed that the samples responded effectively to chloramphenicol (29%), gentamicin (28%), imipenem (26%), and amikacin (21%). High degree of resistance was shown for nalidixic acid, ciprofloxacin, norfloxacin, amoxyclav, and ofloxacin. Conclusion: Antibiotics have been in use for a long period and more often the misuse of antimicrobial drugs has today led to a general rise in the emergence of resistant bacteria. This study may aid health professionals in choosing the appropriate treatment for patients in North-Eastern India.
