Transmissible Porcine Gastroenteritis (TGE) is a highly contagious viral disease that affects swine, particularly piglets. It is caused by a coronavirus known as porcine epidemic diarrhea virus (PEDV). TGE primarily affects the gastrointestinal tract of pigs, leading to severe diarrhea, dehydration, and high mortality rates, especially in newborn piglets.
The virus spreads through direct contact with infected animals or fecal-oral transmission, meaning it can be transmitted through contaminated feed, water, or equipment. TGE can also be transmitted by humans who have come into contact with infected pigs or their biological materials.
The symptoms of TGE include watery diarrhea, vomiting, loss of appetite, and depression. Piglets are particularly susceptible to the disease, with mortality rates reaching up to 90% in infected litters. Adult pigs can also be affected, but usually show milder symptoms.
Due to its highly contagious nature and severe impact on pig production, TGE is considered a significant economic threat to the swine industry. Outbreaks can result in significant financial losses for pig farmers and can also affect pork supply chains.
Prevention of TGE mainly involves strict biosecurity measures, such as quarantining infected pigs, disinfection of premises and equipment, and limiting contact between pigs from different sources. Vaccination is also available in some regions to help reduce the impact of the virus on pig herds.
In summary, Transmissible Porcine Gastroenteritis is a highly contagious viral disease of pigs that primarily affects the gastrointestinal tract, leading to severe diarrhea and high mortality rates, especially in piglets. It poses a significant economic threat to the swine industry and requires strict biosecurity measures for prevention and control.
