Abstract
Background and Objectives
Aerobic, nonfermenting gram-negative bacilli (non-fermenters) are now emerging as important uropathogens. This study was done to know the prevalence of non-fermenters in Urinary Tract Infections (UTI) along with their antibiotic sensitivity.
Method
1361 mid stream urine specimens received in 18 months period from December 2012 to July 2014 were subjected to Gram, staining ,semi-quantitative culture, biochemical tests and antibiotic sensitivity testing as per the standard procedures in the routine microbiology laboratory and the results were noted.
Results
Out of the 317 culture positive cases with significant bactereuria, 131 (9.7%) were caused by non-fermenters. Among the non-fermenters, Pseudomonas spp. was the most common (80.6%) followed by Acinetobacter spp. (19.3%). Majority of patients belonged to the age group of 15 to 50 years and most of them were females. Antibiotic sensitivity testing revealed that, among Pseudomonas spp., 77.4% isolates were sensitive to Piperacillin, 71.13% sensitive to Amikacin, 41.9% sensitive to Ciprofloxacin, 35.4% sensitive to Ceftazidime and 90% sensitive to Imipenem. In the case of Acinetobacter spp., 68% isolates were sensitive to Amikacin, 33.3% sensitive to Norfloxacin and all were sensitive to imipenem. Out of the 6 non-fermenter isolates which were resistant to commonly used antibiotics, 4 were from inpatients indicating the possibility of nosocomial infection. Conclusion: The non-fermenters are emerging as important cause of Urinary Tract Infections. In this study, Pseudomonas spp. was the most common non-fermenter isolated in significant numbers in MSU specimens. But, Acinetobacter spp. appeared to be more resistant to invitro antibiotics in general.
