This study aims to isolate and evaluate the antibacterial activity of endophytic fungi associated with the bark of &lt;em&gt;C. mercadoi&lt;/em&gt;. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Endophytic fungi were isolated from surface sterilized bark samples aseptically. The pure isolates were identified through their morphological characteristics. Agar plug diffusion assay was employed in the primary screening of their antibacterial activity against &lt;em&gt;Staphylococcus aureus&lt;/em&gt;, &lt;em&gt;Bacillus cereus&lt;/em&gt;, &lt;em&gt;Escherichia coli &lt;/em&gt;and&lt;em&gt; Pseudomonas aeruginosa.&lt;/em&gt; Four active endophytes were fermented and extracted with ethyl acetate (EtOAc). The antibacterial activity of the EtOAc extracts was screened using the disk diffusion assay. The minimum inhibitory activity (MIC) was evaluated using the microdilution method. &lt;strong&gt;Results:&lt;/strong&gt; Twelve (12) endophytes were isolated from the bark of &lt;em&gt;C. mercadoi&lt;/em&gt;. All endophytes exhibited antibacterial activity on at least one of the test pathogens. However, only two of the four endophytes subjected to the secondary screening showed wide-spectrum activity and inhibited the growth of all test bacteria. &lt;em&gt;Fusarium&lt;/em&gt; sp. 2 was identified to have the most promising activity with MIC values ranging from 2.1 - 4.2 mg/mL. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;C. mercadoi&lt;/em&gt; harbors endophytes, particularly &lt;em&gt;Fusarium&lt;/em&gt; sp. 2, which possess antibacterial activity and thus a potential source of antibacterial compounds.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">405</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Jia P.
