Transmissible Enteritis of Turkeys (TET) is a highly contagious viral disease primarily affecting turkeys, but can also impact other birds such as chickens and pheasants. It is caused by the turkey coronavirus and is characterized by inflammation and damage to the intestines.
TET is primarily transmitted through the oral-fecal route, meaning that infected birds shed the virus through their feces, which can contaminate the environment and infect susceptible birds. The virus can also be transmitted through direct contact with infected birds or contaminated items such as feed, water, and equipment.
The disease usually affects young turkeys, particularly between the ages of 3 and 10 weeks. Infected birds may display symptoms such as loss of appetite, depression, diarrhea, dehydration, and weight loss. Mortality rates can vary, but can be high, especially in severe outbreaks and in young birds. Older turkeys may show milder symptoms or remain asymptomatic.
Diagnosis of TET is based on clinical signs as well as laboratory tests, such as serological tests to detect antibodies against the virus and viral isolation from affected tissues.
Prevention and control of TET primarily involve strict biosecurity measures, including quarantine and disinfection protocols to prevent the introduction and spread of the virus. Vaccination of susceptible birds plays a crucial role in preventing and controlling the disease. Additionally, maintaining good sanitation practices, proper hygiene, and avoiding overcrowding can help reduce the risk of TET infection.
