BACKGROUND: In countries with a high prevalence of tuberculosis there is high coincident of helminth infections that might worsen disease outcome. While Mycobacterium tuberculosis (Mtb) gives rise to a pro-inflammatory Th1 response, a Th2 response is typical of helminth infections. A strong Th2 response has been associated with decreased protection against tuberculosis. PRINCIPAL FINDINGS: We investigated the direct effect of helminth-derived antigens on human macrophages, hypothesizing that helminths would render macrophages less capable of controlling Mtb...

Infection with helminth parasites has been explored as a treatment for autoimmune and inflammatory diseases. As helminth antigens have potent immunomodulation properties capable of inducing regulatory programs in a variety of cell types, transferring cells treated with helminth antigens represents a novel extension to helminth therapy. Previous work determined that transfer of bone marrow-derived dendritic cells (DC) pulsed with a crude extract of the tapeworm Hymenolepis diminuta (HD) can suppress colitis in recipient mice...

In present study the systematic and taxonomic position of hymenolepidids parasitizing rodents of the family Gliridae from Europe and Central Asia is discussed. Hymenolepis myoxi is redescribed on the basis of the type material from the fat dormouse Glis glis deposited in the collection of the Museum für Naturkunde, Berlin, Germany. Significant corrections of morphologically distinctive characters attributable to H. myoxi include: (1) recognition of a rudimentary rostellar apparatus; (2) absence of rostellar hooks and spination on the suckers; and (3) tissues of the scolex and neck filled with numerous "firm elements"...
