Veterinary Pathology Quiz

A type of Clostridium perfringens infection in sheep and goats that causes severe inflammation in the intestines, leading to bloody diarrhea and potential death.

A toxin produced by Clostridium perfringens type D, responsible for the deadly intestinal inflammation seen in Clostridial enterotoxemia.

The primary site of damage in Clostridial enterotoxemia, characterized by acute inflammation, necrosis, and bleeding.

A characteristic finding of Clostridial enterotoxemia, where the intestinal lining shows signs of intense inflammation and cell death.

A manifestation of Clostridial enterotoxemia type C in calves, lambs, and piglets.

Necrosis occurring around the central vein of a liver lobule, often caused by acetaminophen toxicity or chronic passive congestion.

A type of hepatic necrosis affecting hepatocytes located halfway between the central vein and the portal area. It can be caused by certain plants like Cocklebur.

Excess fibrous connective tissue replaces damaged liver cells, leading to scarring and potential loss of liver function.

The 'end stage' of liver disease, characterized by nodular regeneration of liver tissue combined with extensive fibrosis. This makes it very difficult for the liver to function properly.

A condition in ruminants, specifically cattle, where the abomasum, the fourth stomach compartment, is affected by a parasitic infestation. This infestation is caused by the parasite Ostertagia ostertagi.

This condition is characterized by an inflammation of the abomasum in cattle, caused by Clostridium perfringens bacteria. This bacterium produces toxins that damage the lining of the abomasum, leading to inflammation and potential complications.

A condition where the lining of the abomasum in cattle is ulcerated and inflamed. This inflammation is caused by fungal organisms (mycotic).

This is a condition characterized by an excessive accumulation of fluid in the abdominal cavity (abdomen) of cattle. This fluid build-up is often caused by the growth of malignant cells in the mesothelial lining of the abdominal cavity.

This condition refers to a severe metabolic disorder seen in cattle, particularly dairy cows, that is caused by an excessive intake of readily fermentable carbohydrates, such as grains. The rapid fermentation of these carbohydrates in the rumen produces excessive lactic acid, which can cause a dramatic drop in the rumen's pH, leading to various complications.

A type of lung disease causing inflammation and thickening of the lung tissue. It is commonly caused by bacteria like Pasteurella and in sheep, by a slow virus causing Ovine Progressive Pneumonia (OPP).

A disease primarily affecting sheep, characterized by a gradual thickening and fibrosis of lung tissue. It's caused by a lentivirus (similar to HIV) and leads to respiratory problems.

A type of lung inflammation caused by the bacterium Pasteurella. It usually involves more severe inflammation in the air sacs and bronchioles (small airways).

An infection of the lung in cattle caused by the bacterium Haemophilus somnus. It often results in pneumonia and can spread to various organs.

A type of lung infection caused by a roundworm parasite called Dictyocaulus viviparous. The worms live in the bronchioles of the lungs, causing coughing, labored breathing, and sometimes pneumonia.

A disease that primarily affects puppies and is caused by a virus. It is characterized by necrosis (cell death) and hemorrhage (bleeding) in the liver, leading to inflammation.

An infectious disease affecting both humans and animals, primarily ruminants. It is characterized by extensive necrosis (cell death) and hemorrhage (bleeding) in the liver, often leading to abortion and death in affected animals.

A bacterial infection that can cause abortion in sheep. The bacteria cause necrosis (cell death) in the liver, resulting in characteristic circular lesions.

A type of infection that involves the formation of granulomas (clumps of immune cells) in the liver. These granulomas contain multinucleated giant cells, which are cells with multiple nuclei.

A condition that can be caused by flukes, particularly Fasciola hepatica and Fascioloides magna. It affects ruminants and can cause necrosis (cell death) and fibrosis (scarring) of the liver.

A parasitic infection caused by the fluke Fascioloides magna. This fluke is not a normal parasite in cattle and therefore causes more severe lesions compared to other animals.

A form of parasitic hepatitis caused by the fluke Fasciola hepatica. This fluke infects the liver, causing necrosis (cell death) and fibrosis (scarring) of the biliary tree.

Cleft palate is a congenital anomaly of the mouth, where the roof of the mouth (palate) doesn't close completely during fetal development, leaving an opening.

A short lower jaw (mandible) is referred to as Brachygnathia inferior. It's one of the many jaw abnormalities that can develop in animals.

Prognathia Inferior refers to an excessively elongated lower jaw (mandible), another type of congenital jaw abnormality in animals.

Stomatitides encompass inflammation of various mouth structures, including lips, pharynx, tongue, gums, tonsils, and palate. They can be caused by various factors, ranging from infections to trauma.

Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting cloven-hoofed animals like cattle, pigs, sheep, and goats. It causes widespread blisters on the mouth and feet, leading to significant economic losses.

Malignant Catarrhal Fever (MCF) is a serious, often fatal, viral disease that primarily affects cattle, sheep, and goats. The virus attacks the respiratory and digestive systems, causing severe inflammation and internal bleeding.

Salmonella is a genus of rod-shaped, gram-negative bacteria that commonly cause food poisoning in humans and animals. It can lead to severe illness, including diarrhea, abdominal pain, fever, and even death.

Wooden Tongue is a bacterial disease caused by Actinomyces bovis, affecting cattle primarily. It causes a chronic inflammation of the tongue, leading to swelling and difficulty in feeding.

Lumpy Jaw is a chronic, granulomatous infection caused by Actinomyces bovis primarily affecting cattle. It results in a hard, lumpy swelling of the jawbones, sometimes leading to difficulty in chewing.

Enterotoxemia, caused by Clostridium perfringens type A, is a condition where toxins produced by bacteria in the gut cause severe damage to the lining of the intestines, leading to diarrhea, dehydration, and even death.
