Abstract

The most common and wide types of infections are Respiratory tract infections (RTIs), known for high morbidity and mortality in medicine. This study was conducted to determine the microbial pathogens responsible for respiratory tract infections and their antimicrobial susceptibility pattern. Total 130 sputum and 70 swabs were collected and processed according to standard laboratory procedures Absyn University Peshawar, Pakistan microbiology laboratory. The samples were processed to screen pathogenic bacteria causing respiratory tract infections. Of all samples, the most prevalent bacteria were enterococcus (29.2%) followed S. aureus (27%), S. pneumoniae (14.0%), M. catarhalis (8.4%), K. pneumoniae (7.3%), S. pyogenes (7.9%), and H. Influenza (6.2%). Antibiotics susceptibility profile was done to determine resistance level in isolated species against current antibiotics. It concluded that different bacterial species were responsible for URT and LRT infections and were detected as multi-drug resistance. Further molecular research is needed to identify resistance genes among these species
