equine pathology

A bacterial disease in horses primarily affecting the liver. It is often fatal to foals and can cause liver enlargement with multiple small grey spots (miliary foci).

Small, pinpoint-sized spots that are grey in color, often found on the liver in cases of Tyzzer's disease.

Inflammation of the intestines with necrosis (tissue death).

Yellowing of the skin and tissues due to bilirubin accumulation

Inflammation of the brain and its membranes, often a sign of infectious disease.

An infectious disease caused by the bacteria Actinobacillus equuli, often characterized by lethargy and neurological signs in foals.

A highly contagious viral disease in horses that can cause a variety of symptoms including fever, respiratory distress, neurological signs, and abortion.

Bacteria present in the intestines of horses that can cause infections, including those related to Tyzzer's disease.

Necrosis in multiple areas of the liver, often with surrounding hemorrhage and inflammatory cells.

Inflammation of the liver characterized by pus and small, granular clumps of tissue.

Inflammation of the intestine, often with tissue death, commonly seen in foals and other animal species.

Small pockets of pus within the intestinal lining.

Areas of dead tissue in the heart muscle.

Bacteria spreading through the bloodstream to various organs.

Bacteria colonizing and multiplying within the liver tissue.

Groups of bacteria found within the cells lining the intestines.

A disease of horses caused by parasitic strongyles, specifically Strongylus vulgaris, that affects the cranial mesenteric artery. It involves larval migration in the artery and causes inflammation, thrombosis, and potential bowel perfusion disruption.

A symptom of Strongyle Arteritis. It's characterized by sudden abdominal pain, colic, and potential for bowel ischemia. Occurs due to interruption of blood flow caused by thrombosis or vascular damage.

A specific type of strongyle, also known as the large strongyle, causes Strongyle Arteritis. The larval form of this worm migrates through the blood vessels and can cause damage to the cranial mesenteric artery.

The cranial mesenteric artery is a key artery in the horse's digestive system. Strongyle Arteritis primarily affects this artery due to the larva’s tendency to migrate through it.

A chronic inflammatory process in the cranial mesenteric artery, characterized by thickening of the vessel wall due to inflammation and fibrosis (scarring). This leads to narrowing of the artery and potential blockage.

A serious consequence of inflammation and thrombosis in the cranial mesenteric artery. It can disrupt blood supply to the intestines, possibly leading to diarrhea, colic, and even death.

The L3 larval stage of strongyles is the infectious stage. These larvae are ingested by horses and mature in the intestines. Certain strongyles, like Strongylus vulgaris, migrate throughout the circulatory system.

The primary route of Strongylus vulgaris infection in horses. Ingesting contaminated food or water containing L3 larvae allows the parasites to enter the horses and initiate their migration in the body.

Inflammation of the kidneys, often caused by bacteria entering the bloodstream and forming small abscesses within the kidney tissue.

Small, white spots on the surface of the kidneys, indicative of inflammation and bacterial colonies.

Tiny blood clots that travel through the bloodstream and lodge in various organs, often carrying bacteria that cause infection.

Bacteria that normally resides in the body without causing illness, but can become harmful under certain conditions.

A condition where bacteria spread throughout the bloodstream, potentially leading to infections in various organs.

The process by which a disease develops and progresses.

The presence of bacteria in the blood, indicating a systemic infection.

The spread of bacteria from one location within the body to other parts, often via the bloodstream.

A bacterial disease in horses caused by Rhodococcus equi, often affecting young foals and characterized by lung abscesses and other clinical signs.

The bacteria Rhodococcus equi naturally lives in the soil and the digestive system of herbivores, making it a common environmental exposure.

Young foals are more susceptible to Rhodococcus equi infection due to their developing immune systems. They often haven't received enough passive immunity from their mother's colostrum.

The bacteria Rhodococcus equi spreads through the air when contaminated dust is inhaled, affecting the respiratory system.

Inflammation of the lungs with the formation of pus-filled cavities (abscesses). This is the most common finding in Rhodococcus equi infection.

Enlarged and inflamed lymph nodes in the abdominal cavity, often a sign of Rhodococcus equi infection.

Inflammation of the intestines with multiple ulcers, often seen in cases of Rhodococcus equi infection.

The presence of pus-filled nodules (clumps of tissue) centrally surrounded by areas of dead tissue. This is a characteristic finding in Rhodococcus equi infection.

A condition in horses caused by the bacterium Clostridium botulinum, resulting in paralysis and difficulty swallowing.

A serious complication of Strongyle Arteritis, with symptoms like colic and potentially bowel ischemia.
