Pulmonary Ovine Adenomatoses is a respiratory disease that primarily affects sheep and is characterized by the development of benign tumors within the lungs. This condition is caused by a retrovirus known as Jaagsiekte sheep retrovirus (JSRV).
The term "pulmonary" refers to the involvement of the lungs, as this disease primarily affects the respiratory system. "Ovine" refers to its specific occurrence in sheep. "Adenomatoses" indicates the development of tumors, known as adenomas, which are typically benign and non-cancerous.
The tumors associated with Pulmonary Ovine Adenomatoses originate from secretory epithelial cells in the lungs, resulting in the excessive production of mucus. This overproduction of mucus leads to respiratory distress and compromised lung function.
The disease is primarily transmitted horizontally, meaning it can spread between sheep through direct contact or inhalation of respiratory secretions. Vertical transmission from mother to offspring can also occur.
Symptoms of Pulmonary Ovine Adenomatoses include persistent coughing, respiratory distress, increased respiratory rate, decreased exercise tolerance, and weight loss. The disease progresses slowly and eventually leads to severe respiratory impairment and eventual death.
There is no specific treatment for Pulmonary Ovine Adenomatoses, and control measures primarily involve culling or separating affected animals from the flock to prevent further spread. Enhanced management practices, biosecurity measures, and vaccination programs may also play a role in disease prevention.
