What causes guttural pouch mycosis?

Guttural pouch mycosis is a fungal infection in the guttural pouch caused by a common fungi that most all horses carry. The fungus has an affinity for growing on the surface of the guttural pouch overlying the nerves and arteries.

What is the most common infectious agent in guttural pouch empyema?

The most common bacterial species that result in guttural pouch empyema include Streptococcus zooepidemicus and Streptococcus equi. Treatment is often frustrating because of the cost and duration of guttural pouch lavages, systemic antibiotics, and antiinflammatories required to clear the exudate and infection.

What clinical signs are associated with an infection of the guttural pouch?

Signs include intermittent nasal discharge that contains pus, painful swelling, and in severe cases, stiff head carriage and noisy breathing. Fever, depression, and loss of appetite may or may not be seen. A diagnosis can often be made after endoscopic examination of the guttural pouch.

Where are Chondroids found in horses?

They are located near the throatlatch region of the neck. Major vessels and nerves supplying the head course through the walls of the pouch. The pouch is accessed with an endoscope through a small slit in the pharynx.

What is the most common cause of esophageal disease in the horse?

Esophageal obstruction (choke) is a condition in which the esophagus is obstructed by food masses or foreign objects. It is by far the most common esophageal disease in horses. Obstruction is most common when a horse quickly eats dried grain, beet pulp, or hay.

Why do horses have a guttural pouch?

Recently, investigators determined that the equine guttural pouches function during selective brain-cooling to maintain blood carried by the internal carotid arteries at a temperature below the core body temperature during hyperthermia, induced by exercise.

What does the guttural pouch connect?

The guttural pouches connect the middle ear to the pharynx. The opening into the pharynx is called the nasopharyngeal ostium, which is composed of the pharyngeal wall laterally and a fibrocartilaginous fold medially.

What does strangles do to a horse?

Strangles is a highly contagious infection that causes fever, nasal discharge and abscesses near swollen lymph nodes. Hot packs can help the abscesses mature before opening and flushing them out. Horses that struggle to breathe may need antibiotics or hospital care.

What causes a horses tongue to swell?

Actinobacillus lignieresii primarily causes large abscesses of the tongue, a condition often called wooden tongue. The tongue becomes hard and swollen, leading to drooling and difficulty eating.

What is the main and fatal complication of strangles?

The most common fatal complication is the development of suppurative necrotic bronchopneumonia secondary to the aspiration of pus from internal ruptured abscesses or metastatic infection of the lungs. Guttural pouch infection with empyema may also result from rupture of abscesses in the retropharyngeal lymph node.

Which bacteria is a common cause of Pleuritis in horses?

Anaerobic bacteria are isolated from 40%–70% of horses with pleuropneumonia; Bacteroides spp, Clostridium spp, Peptostreptococcus spp, and Fusobacterium spp are the most common.

What are two clinical signs of strangles?

Clinical signs of strangles can include fever, lethargy, nasal discharge, soft cough, reluctance to eat or drink, abnormal head positioning, and swelling and abscessation of lymph nodes. The abscessed lymph nodes can become enlarged, hard and painful and can block the airways of the horse (hence the name strangles).

How do you flush a guttural pouch?

Balanced electrolyte solutions with acetylcys- teine, dimethyl sulfoxide (DMSO), or a combination of antimicrobials can be used to flush the guttural pouches. Dilute povidone-iodine solutions (1%) are also used; however, iodine can be neutralized by exudates.

What are bastard strangles?

Metastatic strangles (sometimes called “bastard strangles”) is a condition in which lymph nodes in other parts of the body, such as the abdomen and chest, are affected. The diagnosis of strangles is confirmed by bacterial culture of secretions from abscesses or nasal swab samples.

Do horses survive peritonitis?

Mortality rates can be as high as 59.7%, with horses developing postoperative peritonitis having a 56% mortality rate. Long-term complications like adhesion formation or internal abscesses may further reduce the survival rate. The prognosis is best determined by an early and quick response to aggressive treatment.

What digestive disorder is fatal in horses?

Colitis-X. Colitis-X is a term used to describe undiagnosed causes of an extremely rapid, fatal intestinal inflammation of horses that causes a sudden onset of profuse, watery diarrhea and development of shock. Many affected horses have a history of stress.

Acid reflux disease is the most common cause of dysphagia. People with acid reflux may have problems in the esophagus, such as an ulcer, a stricture (narrowing of the esophagus), or less likely a cancer causing difficulty swallowing.

What causes laryngeal paralysis in horses?

Laryngeal Hemiplegia (Roaring)
Paralysis is caused by a gradual deterioration of nerve fibers in the larynx, leading to deterioration of the associated muscles. Because muscle control is lost, the cartilage in the larynx can collapse, reducing the size of the airway through which the horse breathes.

Why do they put metal in horses mouths?
