Trends in the assessment of multidrug efficiency against identified bacterial strains isolated from wounds at El-Demerdash Hospital, Egypt

Multidrug-resistant (MDR) bacteria is a severe problem for universal public health which increases morbidity and mortality rate. These resistant bacteria lead to ineffective treatment of drugs resulting in the spreading and persistence of infections. So, the major target of this study is to estimate the competence of multidrug antibacterial agents against bacterial strains isolated from wound samples and then identify the most potent Multidrug-resistant (MDR) bacteria. Fifty wound swab specimens were gathered from various wounds and several patients from the Central Microbiology Laboratory of El-Demerdash Hospital, Cairo, Egypt. Eightynine bacterial isolates were isolated from fifty wound samples then cultured on different media and tested for their susceptibility to different thirty antibiotic discs using the agar disc diffusion method. After recording the results of the susceptibility test, the post potent resistant bacterial isolates recorded 3 bacterial isolates which resistant to 30 different antibiotic types. These resistant bacterial isolates were identified using morphological, biochemical, and molecular techniques. The results recorded that the post potent resistant bacterial isolates identified as Klebsiella oxytoca, Pseudomonas aeruginosa, and Escherichia coli. This study concluded that with the increase in the random use of antibiotic drugs resulted in the presence of multi-antibacterial resistant strains. There are bacterial strains that were isolated from wounds in patients at El-Demerdash Hospital, Egypt, and identified. They can resist about thirty different antibiotic discs.
