Abstract
Acinetobacter baumannii is an opportunistic bacterial pathogen that is the most important cause of hospital-acquired infections. The objective of this study was to evaluate the predominance and determination of virulence encoding genes in A. baumannii isolates. During this cross-sectional study period from February 2019 to March 2020 of 380 clinical samples including endotracheal aspirates (70), wound swab or pus (175), urine (70) and blood (65) analysed in inpatients admitted to the hospital in different unit like ICU, Surgery and Burn unit of Mymensingh Medical College Hospital. Out of 380 studied samples, 130(34.21%) strains were yielded growth. Among 130 isolates, Acinetobacter spp. was 49(37.69%). Totally, 39(79.59%) were Acinetobacter baumannii which was detected by molecular technique PCR. Further more, the determination of virulence genes csgA and fimH detected by PCR. Among two studied virulence genes, csgA (38.46%) was the most prevalent virulent genes associated with disease severity and co-morbidity of the patient in A. baumannii infections.
