Lower Respiratory tract infections (LRTI’s) are the most frequent infections among patients. The consequences of increased drug resistance are far reaching since bacterial infection of the respiratory tract (RT) is a major cause of death from infectious disease. The present study was conducted to determine the bacterial etiology and their antimicrobial susceptibility pattern of Gram negative bacteria in lower respiratory tract infections so as to update the clinicians in the various antimicrobial alternatives available in the treatment. Patients with lower respiratory tract infections were collected in time span of six months. | Nội dung Text Antimicrobial susceptibility pattern among aerobic gram negative bacilli of lower respiratory tract specimens of a tertiary care hospital in southern rajasthan India
