Abstract

Acinetobacter baumannii (AB) is a gram-negative bacterium and a main source of nosocomial infection that mainly affect immunocompromised individuals. Methylene blue (MB) is commonly used for staining in microbiology but in this article MB is used as resisting agent against AB. The main aim of this study is to find the most possible cure against A. baunannii. Isolated strains of A. baumannii were subcultured on Muller-Hinton agar (MHA) containing MB and sub-cultured on eosin methylene blue (EMB). Then antibiotic susceptibility testing (AST) and minimum inhibitory concentration (MIC) were determined. The A. baumannii isolates were highly inhibited by EMB medium but showed growth on MHA plates containing MB. The results infer that A. baumannii shows sensitivity against Meropenem. In-vitro studied effect of methylene blue shows inhibition against carbapenem resistance A. baumannii growth was also inhibited by EMB agar. AB strains showed sensitivity against synergistic combinational drugs (Meropenem + Amikacin), (Meropenem + Ciprofloxacin) (Imipenem + Tobramycin), these strains showed resistance against additive combinational drugs (Meropenem + Cefepime) and (Imipenem + Tobramycin), (Ciprofloxacin), (Cefepime) as compared with individually.
