Causative Microorganism of Pneumonia and Antibiotics Sensitivity Pattern on Teaching Hospital in Surakarta, Indonesia

Abstract

Pneumonia still remains as a significant cause of mortality due to the virulence factors of the causative microorganism. The causative microorganism profile of pneumonia differs from one region to another. This study aimed to identify the etiology of pneumonia and bacterial sensitivity pattern to antibiotics. A cross-sectional study was conducted based on reports of bacteria isolates from the ward of Teaching Hospital, from May to October 2018. Microbiological isolates were collected from sputum patient. Identification of all causative microorganisms was performed by standard microbiologic methods. Susceptibility testing was performed using disk diffusion method. Among 47 patient, the subject was dominated by a male (51%) with mean age was 57±2.22. Streptococcus pneumoniae was the most common causative agent (28%) followed by Candida sp. (21%), Pseudomonas aeruginosa (8.8%), Klebsiella pneumoniae (8.8%) and Streptococcus viridans(8.8%). S pneumonia was sensitive to Levofloxacin (81.25%); Ceftriaxone (62.5%); and Ampicillin (75%). Cefoperazone was the only antibiotics showed high effectiveness against P. aeruginosa (83.3%) and K. pneumoniae (100%). Antibiotics susceptibility pattern surveillance should be done periodically.
