Plain-English summary
An 8-year-old male horse had a long-term respiratory infection caused by streptococcus and started showing signs of trouble breathing and abdominal pain. When the veterinarians performed surgery, they found many areas in the intestines that were bleeding and had died off. After the horse passed away, similar bleeding areas were found in the throat and in several muscles. The tissue samples showed severe damage and bleeding, along with inflammation of the blood vessels nearby. This condition looked similar to a disease in humans called anaphylactoid purpura. The vets confirmed that a fungal infection was not the cause. Unfortunately, the treatment did not work, and the horse did not survive.
Abstract
An 8-year-old gelding with a long-standing, streptococcal respiratory infection developed dyspnoea and colic. Laparotomy disclosed numerous, discrete, hemorrhagic, thick areas of necrosis throughout the intestinal tract. At postmortem examination similar lesions were seen in the laryngeal mucosa and in many skeletal muscles. Microscopically these lesions had massive necrosis and hemorrhage with a leucocytoclastic vasculitis in adjacent tissue. This condition resembled anaphylactoid purpura (Henoch-Schönlein disease) in man. Fungal infection was ruled out by special stains which failed to show fungal elements.
