Transmissible Porcine Gastroenteritides (TGE) is a highly contagious viral disease that affects pigs, primarily affecting their gastrointestinal system. It is characterized by severe diarrhea and vomiting, leading to dehydration and ultimately, high mortality rates in pig populations. TGE is caused by a coronavirus known as Transmissible Porcine Gastroenteritis Virus (TGEV).
The virus is transmitted primarily through the oral-fecal route, meaning pigs become infected by ingesting contaminated feces or fluids from infected pigs, or through indirect transmission via contaminated surfaces or feed. TGE primarily affects young piglets, with mortality rates exceeding 90% in piglets less than two weeks old.
The symptoms of TGE can include watery diarrhea, vomiting, loss of appetite, dehydration, depression, and weight loss. The severity and duration of the illness can vary, ranging from a few days to several weeks. The virus primarily targets the epithelial cells lining the small intestine, leading to malabsorption of nutrients and subsequent dehydration.
TGE poses significant economic losses in the swine industry due to high mortality rates, reduced growth rates, and increased costs associated with treatment and prevention. Prevention and control measures include strict biosecurity protocols, such as proper disinfection and hygiene practices, as well as vaccination programs. However, TGEV can rapidly spread within susceptible populations, making strict management practices crucial in controlling and preventing its transmission.
