Trichinella spiralis – Larva encapsulated in muscles (fresh examination)

Apart myocardium, any striated muscle may be parasitized. Preferential localization of larvae depends on Trichinella species, and also on host species. In Man, a pathology diagnosis may be made at 4th week p.i., or over. Muscle biopsy is carried out on deltoide, or intercostal, or tibialis anterior muscles. However, often only serodiagnosis is requested.
