Microbial Analysis of Urine and Antibiotic Sensitivity Pattern of Isolated Infectious Agents from Patients Suffering in Urinary Tract Infection

Abstract

This retrospective study was conducted at the National Institute of Neuroscience & Hospital, Agargaon, Dhaka from October, 2016 to March, 2017 with a view to finding out the incidence of UTI patients with aiming of testing & drug susceptibility. In order to conduct this study, consecutive urine samples of 200 of a total population of both sexes and various age groups were taken from both outpatient and inpatient departments. There were marked gender variations in all age groups, which comprised members between 2 and 80 years of age, and they were requested to provide urine samples for examination. Among them 22.50% of specimens yielded positive culture. UTI is more prevalent in females than in males. The most common isolates were E. coli (15%), Enterococcus sspp . (0.5%), Staphylococcus aureus (2.50%), Staphylococcus saprophyticus (3.50%) and pseudomanas (1.00%) . Azithromycin and ceftriaxone showed the highest sensitivity against E. coli but Nitrofuranton, Gentamicin and Cefixime showed comparatively lower sensitivity against E. coli . Nitrofuranton, and Cefurixime showed the highest sensitivity against S. saprophyticus but Ceftazidime showed the lowest sensitivity against S. saprophyticus. Meropenem showed the highest sensitivity against S. aureus but Ceftriaxone, Ceftazidime, Cefurixime, Amoxyxillin, Gentamicin and Nitrofuranton showed comparatively lower sensitivity against S. aureus . Azithromycin, Ciprofloxacin, Imupenem, Doxycyclin, Co-trimoxazole and Meropenem showed the highest sensitivity against Pseudomonas spp . but Nitrofuranton, Gentamicin, Amoxycillin, Cefurixime, Ceftazidime and Ceftriaxone showed comparatively lower sensitivity against Pseudomonas spp . All the antibiotics used showed 100% sensitivity against E nterococcus spp .
