| Research Abstract |
There is an occurrence tendency in 2 serious viral epidemics in regional areas in Thailand, with distinct features in the timing of outbreak between the viruses. It is not easy for either virus to be transmitted via the cultivation water, and Yellow Head Virus (YHV) has not been detected in major benthos in the cultivation pond. The YHV activity in infected shrimp significantly declined after 24 hours of death. Anti-biotic resistant bacteria were detected in intensively cultivated P. monodon and L. Vannamei. We found relatively very low levels of anti-biotic resistant bacteria in several culture ponds. This suggests that antibiotic-resistant bacteria in farmed shrimps can control by preparation of ponds.
