| Summary: | F OR over one hundred years the microscopic roundworm, Trichinella spiralis, has been known as a parasite of man and many other mam-mals. Its distribution is fairly cosmopolitan with the highest incidence of infection in both man and animals reported in the Northern Hemi- * sphere. The ability of Trichinella to live in a wide variety of hosts and its peculiar life cycle which, unlike that of other nematodes, is completed within the body of a single host, have contributed to its success as a parasite in regions which many parasites find inhospitable. A discussion of the effects of Trichinella upon the body is beyond the scope of this paper. However, it may prove helpful to those readers who have not been trained in medicine or parasitology if illustrations and a brief description of the life cycle of the parasite are included here. Infection is established in the gut when viable larvae are ingested in infected meat (Pls. 1 or 3). As many as 45,000 larvae per ounce have been found in the skeletal muscle of infected hogs. These, released from the meat by digestion, soon reach the small intestine. Here the larvae |
