Moraxella catarrhalis, an aerobic gram negative diplococcus is frequently found as commensal of upper respiratory tract. But over last 20-30years the bacterium has emerged as a genuine pathogen and is now considered as an important cause of upper and lower respiratory tract infections in otherwise healthy children and elderly people. Increased isolation and rise in drug resistant strains of M. catarrhalis has renewed the interest to assess the role of M. catarrhalis in respiratory tract infections and study its antibiotic profile. Sputum specimens were collected for a period of six months. Specimens were screened based on Bartlett’s grading of Gram stain. The screened specimens were put up for culture, biochemical reactions and antibiotic sensitivity testing. Association with various demographic factors was studied. 928 sputum specimens were screened. 498 specimens were processed. M. catarrhalis was isolated in 51(10.24%) specimens. Isolates showed maximum resistance to Ampicillin(60.78%). Most cases belonged to males (64.7%) above 60years age(45.09%). 60.78% cases had risk factor of smoking. Most (52.94%) cases were clinically diagnosed as pneumonia. Moraxella catarrhalis should be considered as significant lower respiratory tract pathogen especially in elderly patients with underlying risk factors. Continued surveillance should be done to decrease emergence of resistant strains.
