Trichinosis
Trichinosis is mainly spread when undercooked meat containing Trichinella cysts is eaten. Most often this is pork, but infection can also occur from bear and dog meat. Several species of Trichinella can cause disease, with T. spiralis being the most common. After being eaten, the larvae are released from their cysts in the stomach. They then invade the wall of the small intestine, where they develop into adult worms. After one week, the females release new larvae that migrate to voluntarily controlled muscles, where they form cysts. The diagnosis is usually based on symptoms and confirmed by finding specific antibodies in the blood, or larvae on tissue biopsy.
