Detection of NDM and OXA-48 Resistant Genes in Acinetobacter Baumannii Isolated FromIntensive Care Units’ Patients Clinical Samples in Khartoum State (original) (raw)

2021

Abstract

Background: Acinetobacter baumannii is an opportunistic bacterial pathogen with intrinsic and acquired resistance to many antibiotics causing high rates of morbidity and mortality. This study was aimed to detect MDR Acinetobacter baumannii and its resistant genes (blaNDM, blaOXA48) from clinical isolates in Khartoum state. Method: A cross sectional hospital-based study was done during the period fromApril to July 2019. A total of 50 clinical isolates were obtained from samples of patients in intensive care units (ICUs) for the purpose of molecular confirming of A. baumannii and detecting NDM and OXA-48 resistance genes by usingconventional PCR. Results: Out of 50 isolates investigated PCR was confirmed 47 (94%) as A. baumannii isolates , while 3(6%) isolates were appeared to be other species. Moreover,the 47 A. baumannii isolates were examined for the presences of resistant genes and the result showed that NDM gene was detected in 2 isolates (4.3%) and OXA-48 gene was detected in on...
