This study aimed to conduct a detailed study on murine model testing of bacteriophage against Acinetobacter baumannii. These bacteriophages were tested not only for their efficacy in healing wound of murine models infected with multidrug resistant A. baumannii but were also studied for any derangement in hematological parameters as well as liver and kidney function. The study also included any histological changes observed in hepatic and renal tissues of the bacteriophage treated murine animals. This experimental study was conducted at Institute of Basic Medical Sciences, Khyber Medical University, Peshawar and Institute of Pure and Applied Biology, Department of Microbiology and Molecular Genetics, Bahauddin Zakariya University, Multan. A. baumannii isolates were obtained from the Microbiology Department, Armed Forces Institute of Pathology, Rawalpindi. Antimicrobial susceptibility was done by using standard procedures and as per Clinical Laboratory Standards Institute guidelines. Bacteriophages were isolated from sewage water samples collected from different hospitals in Multan. These bacteriophages were characterized and finally used for treating the murine model and efficacy of phage as a therapeutic option was determined by using superficial rat wound model. In this study, the isolated lytic bacteriophage was effective in relatively faster wound healing of the infected animals. Moreover, there were no significant hematological or renal and hepatic profile changes in treated animals. Histology of renal and hepatic tissues was also normal as compared to control animals. Our study concluded that the isolated phage could serve as an attractive therapeutic candidate to combat the deadly multidrug resistant A. baumannii. |
