Pseudoparasites

Pseudoparasites

 

invertebrate animals that accidentally penetrate the body of an animal or human being and remain there for some time, alive and causing harm. Some pseudoparasites (for example, the larvae of house flies and gray flesh flies, cheese skippers, and various species of myriopods) can reach the alimentary canal with food and cause a variety of disorders. Sheep maggots are found in wounds and ulcers and some myriopods are found in human nasal passages.

In total, 47 % of all samples contained stages of endoparasites from various parasite classes (Protozoa, Cestoda, Trematoda and Nematoda) and 12 % pseudoparasites such as Acari (e.
Therefore, the oocysts in the feces of these hosts probably represent pseudoparasites that originated in feed or water contaminated with wild bird feces (Lindsay and Blagburn, 1994).
The quick keys to the identification of protozoans, helminths, and arthropods are helpful for distinguishing pseudoparasites from harmful ones.
The images can be searched in categories entitled arthropods, cestodes, nematodes, protozoa, pseudoparasites, and trematodes Each image typically has various magnifications (x 100, 500, 1,000, etc.) as appropriate, as well as the organism viewed in various stains (Giemsa, Trichrome, wet prep, H&E, etc.) as appropriate and various stages (ovum, trophozoite, adult, microfilaria) as appropriate.
Ciliocytophthoria have been reported in respiratory tract specimens, gynecologic specimens, and peritoneal washings.[1-3,5,6,8-11,15] Ciliocytopthoria have been produced experimentally by exposing porcine respiratory epithelium to a wide variety of pathogens and are known to be associated with respiratory disease in horses.[16,17] In humans, ciliocytophthoria have been associated with acute tonsillitis and viral infections.[18-20] Clinical virologists should, therefore, expect these pseudoparasites in respiratory specimens submitted for viral DFA.
