Transmissible Enteritis Virus of Turkeys (TETV) is a contagious viral disease that affects turkeys, characterized by inflammation and necrosis of the intestines. It is caused by a highly infectious virus from the family Astroviridae. TETV primarily affects the young turkey poults, resulting in significant economic losses in the turkey industry.
The transmission of TETV occurs through direct contact with infected birds, ingestion of contaminated feed or water, or contact with contaminated surfaces. The virus has the ability to persist in the environment for extended periods, making it highly transmissible within turkey flocks.
Once infected, the virus replicates in the intestinal cells, leading to the destruction of the lining of the intestines. This results in reduced absorption of nutrients, impaired digestion, diarrhea, and dehydration. Affected turkeys may exhibit symptoms such as depression, inappetence, weight loss, and increased mortality rates.
Preventing TETV involves strict biosecurity measures, such as maintaining clean and disinfected premises, minimizing contact between infected and susceptible birds, and practicing good hygiene protocols. Vaccination can also be employed to reduce the susceptibility of turkeys to the virus.
Prompt diagnosis of TETV is crucial for implementing effective control measures. Laboratory testing, including PCR and serology, can confirm the presence of the virus. Treatment of TETV is mainly supportive, focusing on fluid therapy, electrolyte supplementation, and maintaining optimal nutrition.
In conclusion, TETV is a highly contagious viral disease of turkeys, causing inflammation and destruction of the intestinal lining. It can lead to significant economic losses in the turkey industry, making prevention and control strategies crucial for the overall health and productivity of turkey flocks.
