Necropsy and Forensic Medicine: Rabbits and Poultry

Flashcards covering necropsy timings, viral, bacterial, and parasitic diseases, and nutritional/metabolic disorders in rabbits and poultry as presented in the lecture.

Necropsy Timing (Rabbits)

$2$ hours.

Necropsy Timing (Dogs and Cats)

$8-10-12$ hours.

Myxomatosis (Histology)

Stellate cells with intracytoplasmic inclusion bodies in a loose collagenous matrix with inflammatory cells.

Myxomatosis (Forms)

The classical (nodular) form and the amyxomatous (respiratory) form.

Rabbit hemorrhagic disease

A Calicivirus infection characterized by tracheal hemorrhages, pulmonary congestion, edema, and hepatic necrosis.

Cysticercus pisiformis

The larval stage of Taenia pisiformis found in the peritoneum of rabbits; the adult stage is in the small intestine of dogs.

Tyzzer’s disease

A bacterial infection caused by Clostridium piliforme.

Tularemia

An infection caused by Francisella tularensis, also known as rabbit fever.

Pasteurellosis

The most significant disease of rabbits, caused by Pasteurella multocida, resulting in conditions such as rhinitis, fibrinopurulent pneumonia, and abscesses.

Encephalitozoonosis

A condition caused by the Gram+ microsporidia Encephalitozoon cuniculi, resulting in focal necrotizing encephalitis and microsporidial cysts.

Hepatobiliary eimeriosis

Infection by Eimeria stiedae causing chronic cholangiohepatitis and biliary cirrhosis.

Mucoid enteropathy

A condition in rabbits due to microbial dysbiosis and excessive acidity in the caecum.

Pregnancy toxemia

A condition occurring in obese primiparous rabbits characterized by fatty liver (severe hepatic lipidosis).

Fowl pox

An Avipoxvirus infection with cutaneous (proliferative dermatitis) and mucosal (necrotizing stomatitis) forms, showing Bollinger inclusion bodies histologically.

Infectious bursal disease (Gumboro disease)

Caused by Avibirnavirus (Birnaviridae), leading to acute hemorrhagic bursitis and depletion of B cells in the bursa of Fabricius.

Newcastle disease

A Paramyxovirus infection in chickens characterized by hemorrhagic proventriculitis and severe necrosis of Peyer's patches.

Marek’s disease

A lymphoma of the skin, lungs, and kidneys caused by Gallid herpesvirus 2.

Hjarre’s disease

An avian coligranulomatosis caused by chronic Escherichia coli infection, characterized by multifocal granulomatous hepatitis.

Histomoniasis

An infection by Histomonas meleagridis causing multifocal hepatic necrosis and fibrinonecrotic typhlitis.

Ascites syndrome of broilers

A condition caused by rapid growth and hypoxemia, leading to pulmonary hypertension, right-sided cardiac failure, and ascites.

Deep pectoral myopathy (Green muscle disease)

Ischemic necrosis of the supracoracoideus muscle due to rapid growth and vigorous exercise.

Perosis

Also known as "slipped tendon," caused by Manganese, Biotin, or Choline deficiency; it involves the enlargement of the hock and slipping of the gastrocnemius muscle tendon.

Visceral gout

A metabolic disorder caused by high protein in the diet or dehydration, leading to hyperuricemia and uric acid deposits on organs like the liver and pericardium.
