Enteritis is one of the most common bacterial diseases in Litopenaeus vannamei (Pacific white shrimp). It leads to slow growth, malnutrition, molting difficulties, weakness, and reduced disease resistance. In severe cases, it may cause sudden mass mortality (“sudden death syndrome”). Enteritis also deteriorates water quality, making the pond water sticky, foul-smelling, and prone to secondary problems such as muscle opacity and red body disease.

Maintaining water quality in shrimp ponds requires more than just introducing beneficial microbes; it also demands supplying the nutrients necessary for these microorganisms to flourish. This is precisely the role that carbon sources are designed to fulfill.

Enterocytozoon hepatopenaei (EHP) is a microsporidian parasite that infects the hepatopancreatic epithelial cells of the Pacific white shrimp (Litopenaeus vannamei). This parasite is commonly referred to as the “hepatopancreatic microsporidian” or simply “EHP.” Because it primarily damages the shrimp’s hepatopancreas (liver–pancreas), the disease it causes is widely known as hepatopancreatic microsporidiosis.

Shrimp affected by WFS show slow feeding, stunted growth, and high feed conversion ratios. If not treated in time, the shrimp quickly develop empty stomachs and intestines, emaciation, severe cases of atrophy, and even sudden death, directly impacting farming profitability.
