1. Concepts and Principles of Parasitology Flashcards
(30 cards)
What is the study of symbiosis, especially parasitism?
Parasitology
What is the area of biology concerned with phenomenon of dependence of one living organism on another?
Parasitology
It is concerned primarily with animal parasites of humans, their medical significance and their importance in human communities.
Medical Parasitology
It literally means “living together” which involves transportation, protection, and other advantages to parasites.
Symbiosis
It occurs when two organisms living in close association commonly one living in or on the body of the other.
Symbiosis
TRUE or FALSE.
It is necessary for symbionts to be of different species.
FALSE. Symbionts are of different species but not necessarily.
It is a type of symbiotic relationship where one benefit while the other is neither benefitted nor harmed.
Commensalism
A type of symbiotic relationship that can also be referred as “eating at the same table.”
Commensalism
In commensalism, the organisms that provides the benefits are called ______, while the recipient of the benefits are called ______.
Host (provider), Commensal (receiver)
Give 3 example of benefits or service that can be acquired from symbiotic relationships.
Transportations, Protection, Resources (nutrients)
The relationship between a nematode (Caenorharbditis remanei) and mollusks (snail) is an example of what type of symbiosis.
Commensalism
The interaction between a nematode (Caenorharbditis remanei) and mollusks are strictly for ________ and to avoid __________________.
Dispersal
Harsh environment conditions
It is a special type of commensalism wherein both organisms benefit from one another.
Mutualism
It is a type of obligatory symbiosis because of its physiological dependence on one another, which means one cannot survive without the other.
Mutualism
The interaction between a wood-eating termite and intestinal microbiota (which is an intestinal protozoan) is an example of what type of symbiosis?
Mutualism
How does intestinal microbiota aids the wood-eating termite?
Intestinal microbiota aids in lignocellulose degradation
It is a type of symbiosis wherein two symbionts are merely “travelling together “ and neither is physiologically dependent on the other.
Phoresy
In phoresy, _______ is usually smaller than the other organism and is mechanically carried about by that organism called ______.
Phoront or Phoretic Animal
Companion
TRUE or FALSE.
The relationship between mites and bees is an example of parasitism.
FALSE. It is a phoresy, because mites uses bee as transportation but not inducing parasitism.
A type of symbiosis wherein the symbiont actually harms it host or in some sense lives at the expense of the host. It involves intimate relationship between two species with prolong contact or interaction.
Parasitism
A type of parasite that lives on the surface of its host is called endoparasite.
False.
A type of parasite that lives internally on its host is called endoparasite.
True.
It is a type of parasite that spends at least a part of their lives as parasites to survive and complete their life cycles.
Obligate Parasite
These parasites are not normally parasitic but can become so, if they are accidentally eaten or enter a wound or other body orifice.
Facultative Parasites
