INTRO TO PARASITOLOGY Flashcards
area of biology concerned w the phenomenon of dependence of one living organism on another
parasitology
concerened w the ANIMAL PARASITES OF HUMANS and their medical significance, & importance in human communities
medical parasitology
deals w TROPICAL diseases and other special medical problems of tropical regions
tropical medicine
illness- indigenous to or endemic in a tropical area; mostly parasitic diseases
tropical disease
living together of unlike organisms
symbiosis
symbiotic rel.; 2 species live together, 1 benefit w/o harming/benefitting the other (neutral)
commensalism
symbiosis; 2 mutually benefit from e/o
mutualism
parasite lives in/on host for survival; parasite harms the host
parasitism
biological rel.
- always harm the host; parasite cannot live an independent life
parasitism
biological rel.
- parasite is capable of living independently; does not cause infection to the host
commensalism
biological relationship
- none of them were harmed; parasite and host are dependent upon each other
mutualism
biological relationships
commensalism
mutualism
parasitism
amoebiasis is also known as
amebic dysentry
amoebiasis is caused by
Entamoeba histolytica
entamoeba histolytica lives in the -
intestines
organisms which lives in/body of another organism for GROWTH AND SURVIVAL
parasite
plant/animal that harbors the parasite; larger than the parasite
host
parasites acc. to habitat
- infestation
ECtoparasite
para acc. to habitat
- infection
ENdoparasite
para acc. to rel. w host
- take up PERMANENT residence in and are COMPLETELY DEPENDENT upon the host
obligate
para acc. to its rel. w host
- capable of leading both a FREE and a PARASITIC EXISTENCE even if they are outide the body of host
facultative
para acc. to its rel. w host
- visit the host only during FEEDING time
intermittent
para acc. to its rel. w host
- establishes itself in a host which it does not ordinarily live
incidental/accidental
para acc. to its rel. w host
- remains on or in the body of the host from EARLY LIFE until MATURITY , sometimes for its entire LIFE CYCLE
Permanent
para acc. to its rel. w host
- artifacts mistaken as parasites (pollen, hairs)
pseudoparasite
para acc. to its rel. w host
- lives on the host only for a SHORT PERIOD of time
temporary
para acc. to its rel. w host
- a free living-organism that passes through the DIGESTIVE TRACT w/o infecting the host
spurious parasite
classification of hosts
- harbors SEXUAL/ADULT stages/TERMINAL/FINAL stages of the parasite (HUMANS)
definitive host
classification of hosts
- harbors the ASEXUAL stages/LARVALstages of the parasite (SNAIL)
intermediate host
classification of hosts
- host acts as a TRANSPORTING agent for the parasite; parasite does NOT UNDERGO any development (PRAWNS)
paratenic host
