The study of Total Hemocyte Count and Total Protein Plasma in Shrimp Litopenaeus vannamei infected with Monodon baculovirus

Abstract

The investigation of Total Hemocyte Count (THC) and Total Protein Plasma (TPP) in shrimp
juvenile Litopenaeus vannamei that exposed with Monodon Baculovirus (MBV) was carried
out. Three hundred and sixty shrimps with average weight 7 to 12 g were selected from Heleh
site in Bousher province and transported to Iran Shrimp Research Institute. The shrimp was
acclimated during two days for stress reduction and adaptation. The shrimps were cheeked by
PCR for WSSV, MBV, HPV, TSV, IHHNV and NHP and the result showed they are free of
these diseases. The experiment was designed with selected 60 shrimps in triplicate as
treatment and exposed with MBV during 12 hours and control group with triplicate without
exposing with MBV. The hemolymph was withdrawn from abdominal segments of samples
for measuring THC and TPC evaluation at designed hours (0, 12, 24, 48, 72 and 96). The
PCR test confirmed the MBV in treatment and the control were free of viruses. The results
showed that the difference of THC and TPP value between treatment and control group
during the experiment was significant (P < 0.05). This finding can be used for assessing the
health of shrimp culture and prevention of MBV.
