Trichinella spiralis. Light micrograph of a section through cysts caused by the worm Trichinella spiralis in pork muscle tissue. The muscle and cysts are stained blue. Two circular cysts are visible (at centre right and centre left) enclosing larvae. The cysts are being attacked by white blood cells (red), the right cyst is almost totally engulfed. T.spiralis is a parasitic worm. Human infection, caused by eating contaminated pork, causes Trichinosis. The larvae mature in the intestines and reproduce, spreading around the body, causing fever, pains and forming cysts in the muscles. Magnification: x50 at 6x7cm size. | |
