Clinical aspects of infection with Trichinella spp.
Isolated cases and outbreaks of infection with Trichinella spp. occur frequently throughout the world, sometimes resulting in fatalities. The clinical presentations of signs and symptoms are remarkably constant for most of the species of Trichinella, but in infections with Trichinella nativa and Trichinella britovi, classical symptoms of trichinellosis may be absent. It is important to be able to correlate the clinical presentation of trichinellosis with the life cycle of these helminths in order to make an accurate diagnosis. Knowledge of the epidemiology of the disease enables the physician to identify other potential cases, since most epidemics can be traced back to a common source of raw or undercooked meat. A comprehensive summary relating the most important clinical variables is presented graphically for easy reference to the text. Symptoms and signs are considered in relation to severity of infection. Laboratory findings and diagnostic techniques, including new modalities (e.g., DNA and antigen detection), are discussed. A discussion of treatment and preventive measures concludes our review.
