Aflatoxins (AFs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. Although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

Many shrimp farmers were suffering from White Spot Disease (WSD) onset in last decades. Oscillation of environmental factors could lead mortality in susceptible hosts. The results showed mortality started earliear (36h post inoculation) at 25OC in comparison to the temperature more than 29 OC as well as the salinity of 50 ppt in comparison to the lower degrees of salinities. It is concluded tha...
