The TGE virus, also known as transmissible gastroenteritis virus, is a highly contagious viral pathogen that primarily affects piglets. It belongs to the Coronaviridae family and is responsible for causing transmissible gastroenteritis (TGE) in swine populations. The virus primarily targets the cells lining the intestinal tract, leading to severe inflammation and damage, resulting in multiple gastrointestinal symptoms.
TGE virus is transmitted through direct contact with infected animals or through ingestion of contaminated feces or respiratory secretions. The virus can persist in the environment for extended periods and is resistant to many common disinfectants.
Infected piglets typically display symptoms such as vomiting, diarrhea, dehydration, loss of appetite, and weight loss. The disease can be especially severe in piglets less than two weeks old, leading to high mortality rates, devastating economic consequences for the swine industry.
Diagnosis of TGE virus is usually confirmed through laboratory testing, such as polymerase chain reaction (PCR) or serological methods. Vaccination is commonly used to prevent the spread of the disease, and maintaining strict biosecurity measures can help minimize the risk of transmission within a swine herd.
While TGE virus primarily affects pigs, cases of cross-species transmission to other animals and even humans have been reported, although these instances are rare. Nevertheless, the virus poses a significant threat to the global swine industry and necessitates comprehensive prevention and control strategies to minimize its impact.
