The sanitary workers are more prone to increased risk for several airway symptoms, chronic bronchitis and pneumonitis. Lower respiratory tract infections (LRTI) are more prevalent and one of the major causes of death in developing countries. Respiratory tract contains a number of distinct ecosystems, each with its unique microbial flora. The present study was to determine the microbial profile and its antibiotic susceptibility in lower respiratory tract (LRT) of sanitary workers. Seventy nine respiratory samples from LRT of sanitary workers were analyzed. Differential and selective media were used for the identification of bacterial isolates of LRT. Antibiotic susceptibility test has been done to identify the sensitivity of predominant bacterial isolates. Among the isolated organisms, Pseudomonas aeruginosa (P. aeruginosa), Staphylococcu aureus (S. aureus), Streptococcus pneumonia (S. pneumoniae), Beta heamolytic Streptococci and Klebsiella were found to be more prevalent. Antibiotic susceptibility pattern of both Gram positive and Gram negative bacterial isolates of LRTI includes S. aureus and P. aeruginosa shows significantly higher resistance to the antibiotics. Clinical and bacteriological efficacy and its broad spectrum antibiotics of LRTI may be of assistance to find new era of prevention and treatment.
