parasite-host adaptation
evolution of two or more similar species
from a common ancestral stock
What is divergent evolution?
A basic type of immune reaction that is hereditary and not pathogen-specific.
What is innate immune response?
A mode of transmission with parasite infection passed from mother to offspring.
What is vertical transmission?
A symbiosis with a positive fitness effect on the host.
What is mutualism?
The type of adaptive (acquired) immune response that is most effective against protozoal parasites.
Wht is cell-mediated (cellular) immunity?
A disease agent that may be transmitted between animals and humans.
What is a zoonosis (zoonotic agent)?
A low degree of host specificity with a wide host range accepted by the parasite.
What is polyxenic?
A type of antigenic target modification when host-like glykoprotein patterns are presented on the parasite surface.
What is molecular mimikry?
What is tenacity?
The major purpose of parasite morphology and physiological functions.
What is reproduction?
An important signaling protein that allows the host phagocyte activation and initiation of adaptive immunity. Produced by NK cells.
What is interferon gamma?
An agent that carries a parasite and transmits it to another host without being part of the parasite's life cycle.
What is a mechanical vector?
A type of host adaptation to parasites, such as self-selection of plants and adaptation of defecation habits.
What is a behavioral change/adaptation?
The expression of anti-inflammatory messenger substances by the parasite to counteract the host immune response.
Wat is immunosuppression?
A negative feature that limits the multiplication potential of a parasite.
What is the pathogenicity?
