The Antibiotic susceptibility test were carried out on the <i>Staphylococcus aureus</i> isolates.&nbsp; <i>Staphylococcus aureus</i> isolates were more susceptible to Meropenem, Augmentin, Tetracycline, Ceftazidime, Cefuroxime, and Cephalexin. A total of 206 <i>Staphylococcus aureus</i> isolates were tested for MRSA using Cefoxitin disc diffusion, and 43.69% (n=90) were methicillin resistant. A total of 20 <i>Staphylococcus</i> <i>aureus</i> isolates suspected to be MRSA were tested for mecAgene and only 4 isolates (20% of the total isolates tested by Polymerase Chain Reaction) were positive for mecAgene.</span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span sans-serif="" style="font-family:Calibri,"><b><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">Conclusion&nbsp;&nbsp;&nbsp;&nbsp; </span></span></b><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">The presence of MRSA in the two tertiary hospitals poses a risk to healthcare and community environments by contaminating healthcare workers, patients, and visitors with contaminated surfaces. </span></span></span></span></span><br> &nbsp; Staphylococcus aureus, healthcare workers, MRSA, inanimate surfaces. 0 0 http://mlj.goums.ac.ir/browse.php?a_code=A-10-1906-1&slc_lang=en&sid=1 Ebubechi Okey-kalu ulomamgbeokwere@yahoo.com 100319475328460032373 100319475328460032373 Yes Nnamdi Azikiwe University, Awka Ikechukwu Okoli ik.okoli@unizik.edu.ng 100319475328460032374 100319475328460032374 No Nnamdi Azikiwe University, awka Emmanuel Onwubiko get2knowgentlee@gmail.com 100319475328460032375 100319475328460032375 No Michael Okpara University of Agriculture Umudike,Abia state
