Antimicrobial Activity of Zinc Oxide, titanium Dioxide and Silver Nanoparticles Against Mithicillin-Resistant Staphylococcus aureus Isolates

The different investigation has been carried out on the biological activities of silver, zinc oxide and titanium dioxide nanoparticles. But no study till now identified activity particles' size or type, nor a proved their best synergism with antibiotics in one experiment against same isolates.
 In this sizes three types nanoparticles (NPs) was used to detect antibacterial methicillin resistant Staphylococcus aureus, which isolated from patients (with burns wound) at Erbil hospitals. Different also, evaluated isolates. Mithicillin-Resistant S. aureus (MRSA) isolates showed multidrug-resistant most using like; ampicillin, amoxicillin, gentamicin, tetracycline clindamycin erythromycin. minimum inhibitory concentration (MIC) these then conjugated nanoparticles' MIC show effect by well diffusion method.
 results that phenotypic inhibition zones had increased 2 mm maximum 18 mm, confirmed when NPs. These signify nanoparticle potentate antimicrobial action (beta lactums, aminoglycosides, tetracycline, macrolides lincosamides) possible utilization nano compound combination MRSA .
