Abstract :

Background: Urinary tract infection (UTI) is the commonest bacterial infection in community practice. The most common microorganisms causing UTI include E.coli, Klebsiella, Staphylococcus aureus, Coagulase negative staphylococci, Pseudomonas, Proteus and Acinetobacter. The increase in multidrug resistance in bacterial uropathogens is an important and emerging public health problem in non–fermenting isolates. So this study focuses the surveillance of Pseudomonas aeruginosa, and Acinetobacter species in UTI and also focuses the drug resistance of the isolates. Method: The study was conducted at the Department of Microbiology, DM WIMS,Meppadi,Wayanad, starting from May 2019 to July 2019. A total of 200 urine samples were taken for identifying the significant urinary tract infections. Organisms were isolated and identified using standard microbial techniques. Antibiotic sensitivity was studied using Kirby Bauer disc diffusion method and EDTA double disc synergy test. Result: Out of the 200 urine samples studied, 87 showed significant bacteriuria, with 26 (29.9%) Pseudomonas aeruginosa and 6(6.9%) Acinetobacter species. Other isolates were E.coli (24), klebsiella (22), enterobacter (4), Citrobacter (3) and one each were Serratia and Morganella. Among these isolates 15 Pseudomonas aeruginosa and 2 Acinetobacter species were MBL producers. Conclusion: The study reports that other than E.coli, Pseudomonas aeruginosa has a higher prevalence in urinary tract infection and more than half of the isolates are showing drug resistance to the commonly used drugs. Most of the infection with such strains were treated successfully with combination of drugs such as Tigecycline with colistin, colistin with a carbapenem, fosfomycin with a carbapenem, fosfomycin with aminoglycoside, and a carbapenem with an aminoglycoside have been reported as antibiotic combinations effectively administered to series of patients infected with carbapenemase producing organisms
