- Abstract
This study was aimed to know the Survival Rate (SR) and the acute immune response of Pacific white shrimp (Litopenaeus vannamei), including Total Hemocyte Count (THC), bacterial clearance, and prophenoloxidase (ProPO) activity due to infection with Vibrio parahaemolyticus bacteria and its metabolites. Shrimps were infected by bacterial isolates with culture media (A), bacterial isolates without culture media (B), and metabolites suspensions from bacterial culture media (C) for 8 hours with observation every 2 hours. The results showed that SR of experimental shrimps in group A and B were 41.11±26.43% and 62.22±29.98%, respectively. The shrimp in group C still showed the clinical signs but did not cause the mortality (SR 100.00±0.00%). The THC did not show significant changes, either based on experimental groups or duration of infection, but all groups tended to show decreasing THC at 8 hours post-infection. Bacterial clearance and ProPO activity also did not show significant differences between experimental groups or duration of infection at 8 hours post-infection. However, there was an decrease in bacterial clearance activity from 4 to 6 hours post-infection in the experimental groups A and B. Based on the study results, the acute immune response in shrimps did not show significant changes at 8 hours postinfection caused by any infective material. However, shrimps were infected by bacterial isolates with culture media significantly decreased SR compared with the other two groups.
