If the larvae that live in the muscle tissues aren't eaten after several years, they will die and the cyst will completely calcify. The most common way that humans become infected with trichinosis is by eating raw or undercooked pork. People can also become infected by eating wild game, such as bear, cougar, fox, dog, wolf, horse, seal, or walrus. A few days later the victim may still have pains in the joints, headaches and swelling of the face. In addition, severe pain develops in the muscles of the limbs, in the chest, and in the eyes.
Breathing is often painful because the diaphragm becomes heavily infected.
The illness gradually subsides after seven to 14 days, although it can be fatal for about five percent of people. As of now, there is no known specific treatment for trichinosis, but it can be prevented. Cured or smoked pork is not safe for consumption. Specimens were illuminated through Nikon dichromatic filter blocks containing interference filters and a dichroic mirror and imaged with standard epi-fluorescence techniques. All Rights Reserved .
