- <p><span lang="EN-US">The antibacterial activity of a PVP-ZrO<sub>2</sub> nanocomposite was investigated </span><span lang="EN-US">against pathogenic bacteria <em>S. aureus</em> and <em>K. pneumonia</em><span>. A</span>fter antibacterial sensitivity was determined </span><span lang="EN-US">and one isolate was chosen that showed more antibiotic resistance. Herein, the Co-<span>culture</span> technique was used <span>to calculate<em> </em>percent reduction of bacteria.</span> The results that were obtained in this method show that ZrO<sub>2</sub> nanoparticles have inhibitory effect against pathogenic bacteria gram negative bacteria and gram positive bacteria - with the reduction of growth reaching 100% to both, <em>S. aureus</em> and <em>K. pnumoniae</em> at 5, 10, 15, 20, and 25%<span> </span>ZrO<sub>2,</sub> compared with control. The resistance patterns of <a name="_Hlk500975072"></a><em>S. aureus</em> and <em>K.pnuemonia </em>isolates show the Moxifloxacin (MXF) is the best antibiotic for<em> </em>both bacteria - with sensitivity at 100%, while resistance to Ceftriaxone (CRO) is at 90% to <em>S. aureus, </em><span>and at</span> 80% to <em>K. pnumoniae</em>.<span> The polymer-nanocomposite was prepared by</span></span><span lang="EN-US"> weight <a name="_Hlk501255439"></a>percentage (</span><span lang="EN-US">wt%)</span><span lang="EN-US"> of (PVP) being dissolved in 10 mL of distilled water</span><span lang="EN-US">, with the weight percentages 5, 10, 15, 20, and 25 wt% of ZrO<sub>2</sub> nanoparticles added</span><span lang="EN-US">.</span><span lang="EN-US"> </span></p>
