Microbial Etiology of Pneumonia: Epidemiology, Diagnosis and Resistance Pattern

Background: In general, pneumonia is defined as the presence of a recent pulmonary infiltrate and signs that was brought on by an infectious agent, such bacteria, viruses, fungi, or parasites. The fifth most common cause mortality globally bacterial pneumonia, causing nearly 2.56 million mortalities each every year across all age groups, with Sub-Saharan Africa, South Asia, Southeast Asia having highest fatality rates. Objective: prevalent etiological its sensitivity to medications, associated conditions were examined in this research patients Methods: medical records treated at National Institute Health, Pakistan from January, 2022 August, served data source for cross-sectional study. Result: Among 121 patients, majority (n=54; 44.62%) older than 64. Majority (n= 109; 90.09%) sample used culture examination sputum. third-generation empirical antibiotic therapies frequently prescribed ceftriaxone (n=59; 48.78%) viccillin SX (n=21; 17.35%). Antibiotics Imipenem (100%), meropenem (96%), Gentamycin (92%) very effective against Klebsiella pneumonia. Conclusion: frequent bacteria identified sputum cultures pneumoniae Acinetobacter sp. Imipenem, meropenem, gentamycin have demonstrated encouraging outcomes, however sp., Pseudomonas resistance Isolate, Tetramycin, Ciprofloxacin Ceftazidime when compared other antibiotics.
