lavman
deals w/ parasite that cause human infection and the disease they produce he divided into two parts
Medical parasitology
organism that obtains nutrients and shelter from another living organism or host at the expense of the host health
parasite
study of helminths or worms capable of causing disease in humans
medical helmintology
living organism that harbors a parasite and provides with nourishment and shelter
host
deals with study or the animal like protists which are significant parasites of humans
medical protozoology
two organism benefit with each other example termites and the flagellates inside their digestive system
mutualism
living organism that transmit infectious agents from one infected individual human or animal to another susceptible individual
vector
one species benefits from the relationship without harming or benefiting the other example etamoeba coli and human
commensalism
organism that take part in parasitic symbiosis or parasitism
-organism that live for its survival at the host
parasite
one organism lives in or another for its survival at the expense of the host example ascaris lumbricoides and human
parasitism
parasites which lives within the body of host infection is term that denotes the persons of
endoparasite
remains on or in the body of the host for its entire life
permanent
those outside the body of the host
-those on body surface like skin surface
ectoparasite
aka commensals incapable of causing disease
non-pathogenic
lives on the host only for a short period of time
temporary
are organism that harbor the parasites
host
disease causing parasites
pathogenic
one in which the parasite does not develop further to later stage
parasites remains alive and able to infect another host
paratenic
harbors the asexual or larval stage of the parasite
intermediate
parasites at in sexual maturity host in which adult parasite lives
definitive or final
host in which parasite is not usually found
accidental
allows the parasites life cycle to continue and become additional sources of infection
reservoir
cyst of amoeba or flagellates
water
transmit the parasite only after the latter has completed its development within the host
biologic
organism that does not cause disease itself but spreads infection by conveying pathogens from one host to another
vector
those that are only capable of transporting parasite
mechanical or phoretic
another important mode of transmission
hookworm and strongyloides stercolaris enter upon exposure to soil
skin penetration
most common lack of sanitary toilets of the use of night soil or human excreta as fertilizers allow the eggs to come in contact with soil and form the development of specific
soil
most common method foodborne cystodes trematodes intestinal protozoans
oral fecal to oral
transmit parasites through their bites malaria pilarises leishmaniasis trypanosomiasis babesiosis
