Abstract

Acinetobacters.baumannii is an opportunistics pathogenshave a highs incidences through immunocompromised individuals, especially those who have experienced elongated hospital stay. To investigate the prevalence of antibiotics resistance genes of A. baumannii in Iraqi Covid -19 patients. Fifty clinical isolats of out of (86) isolate of A. baumannii were isolated patients attacked with Covid19 from different clinical sources and from different hopsitals. All the clinical samples primarily were cultured on Blood, MacConkey agar. For differentiation A. baumannii, the clinical samples were also streaked on Drigalski Lactose agar medium. Suspected colonies were confirmed by VITEK-2 system. Co infected A. baumannii sample with Covid -19 were subjected to molecular detection with 16srRNA and bla NDM-2 gene. Results of this study found that (50) isolate of A. baumannii with multidrug resistant (MDR) and (XDR) proerties out of (86) isolate of A. baumannii were diagnosed molecularly by 16srRNA and identify 32 (64%) positive sample out of (50) isolates. Also results observed that the 21 (65.6%) sample out of 32 (positively sample for 16sRNA) have COVID-19 infection. Coinfected patients were more in male than female groups ( 76.2% , 23.8% ( respectively. Also result found that antibiotic resistant gene (blaNDM-2) for A. baumannii associated with covid2 were 15 (71.4%) in patient with covid -19. In conlusion the patients attacked with both Covid-19 and A. bumannii are at high risk of longer stay in hospital and potentially death also this study concluded the prevalence of antibiotic resistance among co-infected pateints especially with amikacin and tetracyclin antibiotics.
