Migration and pathogenicity of neurotropic helminths
Pech, Václav ; Horák, Petr (advisor) ; Chanová, Marta (referee)
A neurotropism of helminths can be observed in their intermediate, paratenic and definitive hosts. Neurotropic helminths migrate through the nervous tissue, where maturation and reproduction can take place. The neurotropic helminths can be found in the family of trematodes (Diplostomum baeri, D. phoxini, Ornithodiplostomum ptychocheilus, Trichobilharzia regenti), cestodes (Taenia multiceps, T. solium) and nematodes (Angiostrongylus cantonensis, Elaphostrongylus cervi, Parelaphostronglus tenuis, Baylisascaris procyonis). Presence of these helminths in the nervous tissue can (usually with contribution of the immune system) lead to neurological or other pathological changes: the infected hosts can even die. Some of the neurotropic helminths (A. cantonensis, B. procyonis, T. solium, T. multiceps) can infect humans as well.

Larval toxocarosis and CNS
Bernardová, Nicol ; Chanová, Marta (advisor) ; Bulantová, Jana (referee)
Toxocara spp. is an obligate endoparasitic worm of digestive system of canine and feline. During its life cycle the larvae of this parasite can get even into humans and encapsulate in their tissues. If the presence of toxocara larvae in body causes clinical manifestation, then we talk about larval toxocarosis. We can divide it into several forms and this bachelor's thesis is focused on neurotoxocarosis which is caused by toxocara larvae in the nervous system. This thesis summarises basic information about toxocara, its life cycle and hosts and also about its extension in the world (epidemiology), diagnosis, model animals and finally focusing on clinical manifestation of neurotoxocarosis. Key words: larval toxocarosis, neurotoxocarosis, Toxocara canis, migration, paratenic host, definitive host
