Maedi-Visna Disease (Ovine Progressive Pneumonia) | Symptoms & Diagnosis | Vet Disease Brief

Описание: Welcome to VetDiseaseBrief! In this video, Dr. Ritik Pachauri discusses Maedi-Visna Disease, a chronic, slow-progressive, and fatal viral disease affecting sheep.
Also known as Ovine Progressive Pneumonia, this disease is caused by a Lentivirus (Retroviridae family) and leads to significant wasting and loss in flocks.

📝 Key Topics Discussed:
• Etiology: Small Ruminant Lentivirus (SRLV) affecting mainly sheep and occasionally goats.
• Transmission: Direct contact, contaminated environments, and vertical transmission via milk (ewe to lamb).
• The Two Forms:
• Maedi (Respiratory): Labored breathing, chronic interstitial pneumonia, coughing, and weight loss.
• Visna (Nervous): Paralysis (hind limbs), meningoencephalitis, and wasting.
• General Signs: "Hard Udders" (Mastitis with normal-looking milk), lameness, and death due to anorexia.
• Diagnosis: Isolation, ELISA, PCR, and AGID.
• Prevention & Control: Since there is no effective vaccine or treatment, control relies on "Test and Cull," strict biosecurity, and isolation of sick animals.
