Online Photo Atlas in Parasitology Zoonotic Parasites
	This practical presents selected parasites, the major importance of which is related to the zoonotic impact. They comprise nematodes, cestodes and protozoa, presented in this order. The minute and short-lived adult intestinal stage of Trichinella spp. is shown together with encapsulated larvae and larvae released from muscle tissue by peptic digestion. Metacestodal stages (cysts) of Taenia saginata and T. solium in cattle and pigs, respectively, are shown. The very small adult tapeworms of carnivores, Echinococcus granulosus and E. multilocularis, are characterized by their small size (<5 mm), shape, specific number of rostral hooklets, and their exceptionally low number of pro-glottids (3-5). They are presented together with examples of hydatid disease (E. granulosus metacestodal stage) in man. The small oocysts of Cryptosporidium spp. (4-5 μm) in faecal smears are demonstrated after mod. Ziehl-Neelsen staining. Speciation can only be obtained after genotyping. Use the drop-down menu in the top right-hand corner to choose infection..
