General Information

Although parasitic infections do not always cause clinically obvious disease, interaction between parasite and host will inevitably result in more or less pronounced, local, or general reaction and thus pathology. This may or may not be related to relevant loss of function of the affected tissue or organ and, depending on the severity of pathological effects and the site of alteration, remains inconspicuous or results in clinical disease or even a lethal outcome. Whatsoever, understanding of parasite-induced pathological alterations is indispensable for proper diagnosis of the associated disease.

Direct Effects

Mechanical injury is caused by many parasite species and particularly obvious for those feeding on blood or tissue or migrating through the body or skin of the host during their developmental cycle. Attachment of parasites will destruct the host tissue at the particular site; however, such defects are generally small and in fact negligible if attachment is...
