dc.description.abstractThe cytotoxicity test of crude methanolic leaf extract using Brine Shrimp Lethality Assay revealed that <i>Alibutbut (Tabernaemontana pandacaqui</i> Poir.) is safe to use in treating <i>vibrio</i>-infected <i>penaeid</i> shrimps. The effectiveness of the <i>alibutbut</i> powder against <i>vibriosis</i> was examined through the determination of the post-larvae 20 (PL 20) <i>penaeid</i> shrimp mortality and the water microbial assay after 48 hours. Percent <i>penaied</i> shrimp mortality (0-6.67%) and microbial count (2.91 x 10^4- 3.26 x 104 cfu/mL) of the plant treatments were significantly lower compared to the negative control (no treatment) that exhibited 50% penaeid shrimp mortality and a microbial count greater than 6.00 x 10^4 cfu/mL. The results of the experiment showed that <i>Alibutbut</i> plant powder is indeed effective in controlling <i>Vibrio harveyi</i> bacteria.
