Abstract This study has been carried out on 100 Patients in GEC which staying for 3 days or more. 100 samples were collected as equal from urine, stool and sputum, and 68 samples were collected from surgical wounds. The total number of specimens was 368. Six different types of isolated bacteria were identified from patient samples associated with nosocomial infections (MRSA, E. coli, K. pneumoniae, P. mirabilis, Ps. aeruginosa and Ps. putida). PVP-Glu-Ag-NPs were found to have a strong effect on E. coli, K. pneumoniae and MRSA until 10-2 and P. mirabilis, Ps. aeruginosa and ps. putida so relieve 10-3. The other two (PVP-Ag-NPs) and (Cit-Ag-NPs) had no impact on all isolated bacteria. The effect of 15 commercial antibiotics from 7 different families have different concentrations was studied on isolated bacteria and the MIC was observed on all isolated bacteria. Based on the aforementioned results, that quinolones family had the highest impact on all types of isolated bacteria associated with nosocomial infections. The study showed that the effect of antibiotics on isolated bacteria from antimicrobial resistance to sensitive when combined with Ag-NPs was shown for example in K. pneumoniae. |
