A study on identification of common aerobic bacterial isolates and their sensitivity pattern from bronchoalveolar lavage in patients with lower respiratory tract infections in a tertiary care hospital
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2017, Vol 5, Issue 5
Abstract
Abstract: Broncho alveolar lavage is a deeper sampling and has considerable value in diagnosing pulmonary infections. Antimicrobial susceptibility tests are mandatory to monitor the efficiency of available antimicrobial agents and the emergence of drug resistance among bacterial isolates. The aim of the study is to isolate and identify the common aerobic bacterial agents in broncho alveolar lavage and to evaluate the sensitivity pattern of all the bacterial agents.Grams staining, acid fast staining and culture was done for all the samples. All the isolates were identified by biochemical reactions. Antimicrobial susceptibility testing was done. The isolates were screened and confirmed for ESBL production.87.1% of isolates were gram negative bacilli with Klebsiellaspp. as the most common isolates (33.3%). 17% of the gram negative isolates was ESBL producers and 66.7% of staphylococcus aureus was MRSA. 11% samples were found to be positive for Acid Fast Bacilli.Precise identification of the causative organisms and timely institution of appropriate antimicrobial therapy based on the prevailing sensitivity pattern of the bacterial isolates could reduce the morbidity and mortality of lower respiratory tract infections.
