cze Abstract:
[cze][eng] Neurotropismus helmintů lze pozorovat v jejich mezihostitelích, paratenických a definitivních hostitelích. Tito helminti využívají nervovou soustavu k migraci tělem hostitele, mohou zde také dospívat a rozmnožovat se. Neurotropní helminty lze najít jak mezi motolicemi (Diplostomum baeri, D. phoxini, Ornithodiplostomum ptychocheilus, Trichobilharzia regenti) a tasemnicemi (Taenia multiceps, T. solium), tak hlísticemi (Angiostrongylus cantonensis, Elaphostrongylus cervi, Parelaphostronglus tenuis, Baylisascaris procyonis). Přítomnost těchto helmintů v NS způsobuje (často s podílem imunitního systému hostitele) neurologické či jiné patologické změny. Nakažení hostitelé pak často hynou. Někteří neurotropní helminti (A. cantonensis, B. procyonis, T. solium, T. multiceps) mohou nakazit i člověka.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.
