Respiratory tract infection is the most common acute illness, ranging from uncomplicated infection like common cold to life threatening infections like epiglottitis and pneumonia. A retrospective study was done to know the prevalence of microorganisms causing respiratory tract infections and determine the susceptibility pattern of bacterial isolates from respiratory tract infection (RTIs).
The study was carried out for one year between January 2013 to December 2013. A total 145 different clinical samples (tracheal aspirate, throat swabs, sputum, oral swabs, nasal swabs and pleural fluid) were collected from patients who attended the hospital from various regions, mostly from North Bengal part of Bangladesh. All clinical specimens were collected aseptically from patients and cultured on the appropriate bacteriological media. All bacteriological isolates were identified by morphology, microscopy and biochemical studies and antimicrobial susceptibility tests were performed by standard methods. Out of 145 samples, 61 samples were positive growth with various pathogens. Out of 61 positive samples 65.57% were males and 34.43% were females. Most of the Prevalent pathogens were Staphylococcus aureus (42.62%) followed by Pseudomonas aeruginosa (26.23%), Escherichia coli (19.67%), Klebsiella pneumoniae (9.84%) and Streptococcus pneumoniae (1.64%).
