The constituents of therapeutic plant extracts play a key role in antimicrobial drug discovery. Extracts of 36 medicinal plant species of Pakistan origin that belong to 33 genera and 24 families were tested against the bacterial strains&nbsp;<em>Staphylococcus aureus</em>&nbsp;and&nbsp;<em>Pseudomonas aeruginosa</em>. In addition the extracts of 23 plant species classified in 21 genera and 17 families were assessed against the bacterial clinical isolates (<em>S. aureus</em>,&nbsp;<em>P. aeruginosa</em>), using the agar well diffusion method. As a result, 10 plant extracts exhibited different properties against the specific bacterial strains. Some plant extracts were also tested against the clinical&nbsp;<em>P. aeruginosa</em>&nbsp;and&nbsp;<em>S. aureus</em>&nbsp;isolates. Among the tested samples, Haleej, Anaar and Kali Mirch exhibited the highest relative percentage inhibition against&nbsp;<em>S. aureus</em>&nbsp;while Kala Zeera, Abhal and Khobani showed the highest inhibition against&nbsp;<em>P. aeruginosa</em>. In addition Anar exhibited the highest inhibition against the clinical&nbsp;<em>S. aureus</em>&nbsp;isolate while Pista followed by Zeera showed the highest inhibition against the clinical&nbsp;<em>P. aeruginosa</em> isolate. The results obtained in our present study might help explain the ethnobotanical importance of the screened plant species for the treatment of conjunctivitis.</p> Plant extracts-Antibacterial activity-Clinical isolates-Conjunctivitis Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2017-JAPS-259
