Introduction Flashcards
If a susceptible host harbors the parasite inside his body, the host is said to be _____.
infected
Parasites found outside the body of the host.
Ectoparasites
Host harboring ectoparasites is said to be _______.
infeSted
Parasites found inside the body of the host.
Endoparasites
Host harboring endoparasites is said to be _______.
infeCted
This is the causative agent of amoebiasis
Entamoeba histolytica
All amoeba are considered non-pathogenic, except
Entamoeba histolytica
Same morphologic characteristics as Entamoeba histolytica, differentiated by means of molecular testing or PCR
Entamoeba dispar
This drug is useful to treat amoebic infection.
metronidazole
Useful specifically for Strongyloides and Filaria.
Ivermectin
Useful for common intestinal parasites
Albendazole
Useful for trematode infections
Praziquantel
Mainstay drug for uncomplicated malaria infection.
Chloroquinone
Which of the following is the mode of transmission of malaria?
Vector-borne
The most effective approach in parasitic disease prevention
Education and information
Black water fever is a complication of what parasitic infection?
Malaria
An organism that lives in or on and obtains its nourishment from another organism
PARASITE
The study of parasites
PARASITOLOGY
Species of animal or plant that harbors a parasite providing environmental and nutritional requirements for the parasite to survive
HOST
A process with characteristic symptoms
DISEASE
Triad of malaria symptoms
fever, chills, sweating
Parasitic invasion INSIDE the body
INFECTION
Parasitic invasion ON the body
INFESTATION
Living carrier (often an insect/arthropod) responsible for transporting parasites from infected to uninfected hosts
VECTOR
Classification of vector where part of parasite development happens in the vector and it will transmit the infective stage of the parasite.
Biologic
Classification of vector where contaminated objects with an infective stage of the parasite and the host accidentally comes into contact or ingested it.
Mechanical
Parasite that cannot survive outside of a host
OBLIGATORY PARASITE
Ascaris lumbricoides, Trichuris trichiura, hookworm are examples of _____ parasite
Obligatory
Parasite that is capable of existing independently of a host
FACULTATIVE PARASITE
______ parasites are found in the environment
Free-living
_______ parasites are found either inside/outside the body of the host.
Parasitic
Host other than the normal one that is harboring a parasite
ACCIDENTAL OR INCIDENTAL HOST
Host in which the adult sexual phase of parasite development occurs
DEFINITIVE HOST OR FINAL HOST
Host in which the larval asexual phase of parasite development occurs
INTERMEDIATE HOST
Final Host of Filaria, Taenia solium, and Taenia saginata
Human
Human is the intermediate host of _____
Malaria
Mosquito is the intermediate host of ______
Filaria
Intermediate host of Taenia solium
Pig
Intermediate host of Taenia saginata
Cattle
Final host of Malaria
Mosquito
Host harboring parasites that are parasitic for humans and from which humans may become infected
RESERVOIR HOST
A example of reservoir host that is parasitic in humans, but may normally be found in pigs that would appear unaffected.
Balantidium coli
Host responsible for transferring a parasite from one location to another
Transport host
No ___ or development occurs in the host of a transport host
transformation
Parasite-harboring host that is not exhibiting any clinical symptoms but can infect others
CARRIER OR ASYMPTOMATIC HOST
Harbors and eliminates parasite spreading the disease, shows no signs and symptoms
CARRIER OR ASYMPTOMATIC HOST
Close association of two organisms in which both are dependent upon each other that life apart is impossible
SYMBIOSIS
Association of two different species of organisms that is beneficial to one and neutral to the other
COMMENSALISM
Entamoeba coli in the intestinal tract is an example of what symbiosis
commensalism
Association of two different species of organisms that is beneficial to both
mutualism
Association of two different species that is beneficial to one at the other’s expense
Parasitism
Relating to commensalism; the association between two different organisms in which one benefits and has a neutral effect on the other
Commensal
Parasite that has demonstrated the ability to cause disease
Pathogenic
