Antimicrobial Susceptibility Patterns of Detected Bacterial Isolates in a Tertiary Care Teaching Hospital: A Cross Sectional Study

Abstract

Antibiotics are the most widely prescribed medications and are regularly used to treat a wide range of illnesses. According to national ambulatory medical care, they are the second most commonly prescribed medications. They are sometimes referred to as miracle drugs. Our sole purpose is to determine the potential effectiveness of specific antibiotics on the bacteria and/or to determine if the bacteria have developed resistance to certain antibiotics to help select the drug(s) that will likely be most effective in treating an infection. This study was conducted to ascertain the current scenario of bacterial susceptibility in all infections to optimize empiric therapy among people of all groups of ages in our hospital. Out of the 219 various specimens analyzed, pathogens were identified in 211 (96.3%) specimens. Sputum indicated almost more than 50% positive cultured result whereas lung abscess indicated least number of pathogens (i.e., 2%). The commonly found bacteria were Escherichia coli, Klebsiella pneumoniae followed by Streptococcus pneumoniae. Highest no. of E. coli isolates i.e., 16 were found in pus. E. coli shows 100% resistance to Macrolides and 100% sensitivity to Polypeptides followed by Carbapenems i.e., 95.9%. Highest no. of K. pneumoniae isolates i.e., 24 were found in sputum. K. pneumoniae shows 100% to Macrolides & Lincosamides and 100% sensitivity to Polypeptides & 95.9% sensitivity to Carbapen E. Highest no. of S. pneumoniae isolates i.e., 19 were found in sputum. S. pneumoniae showed 100% resistance to Lincosamides and 100% sensitivity to Carbapenems, Aminoglycosides & Sulfonamides.
