Parasitologie Flashcards
name 4 parasite types
- protozoa
- metazoa
- ectoparasites
- endoparasites
describe difference between intermediate and final host
intermediate host: asexual reproduction
final host: sexual reproduction
Trypanosomiasis brucei (T. brucei) has an acute and chronic form, which causes which
chronic: T. brucei gambiense
acute: T. brucei rhodesiense
what protein is essential for Trypanosomiasis to survive in its host
variant surface glycoprotein (VSG)
how is VSG involved in Trypanosomiasis antibody resistance
by switching VSG proteins, a resistance colony can arise
3 ways for Trypanosomiasis to evade immune system
- enter immune cells
- control host’s immune system
- colonize in place where immune system can’t reach
which 2 stages can Leishmania acquire and in which host do they occur
- promastigote stage: fly
2. amastigote stage: vertebrate host
which 3 clinical forms (from mild to severe) can Leishmania cause
- cutaneous
- muco-cutaneous
- visceral
3 types of helminths
- trematodes
- cestodes
- nematodes

of the following, give nucleus amount and their stage
trophozoite, schizont, gametocyte
trophozoite: 1 nucleus
schizont: division stage, multiple nuclei
gametocyte: sexual stage, 1 nucleus
which malaria stage (gametocyte, schizont or trophozoite) is essential for transmission
gametocyte
which 2 malaria species use dormancy as survival technique
P. vivax & ovale
which malaria infection is lethal
p. falciparum
which 2 current treatments are used for malaria
combination therapy (sulphadoxine with pyrimethamine), and artemisinin
