Introduction Flashcards
Type of parasite completely dependent on the host?
OBLIGATE PARASITE
Type of parasite capable of living even without a host?
FACULTATIVE/OPPORTUNISTIC PARASITE
Type of parasite that colonize and invade the brain & other sites?
AMPHIZOIC PARASITE
Type of parasite that establishes itself in a host which is does not ordinarily live?
INCIDENTAL/ACCIDENTAL PARASITE?
Type of parasite that remains in the host until maturity or for its the entire life?
PERMANENT PARASITE
Type of parasite that passes through the GIT without manifesting s/sx?
SPURIOUS/CAPROZOIC PARASITE
Type of parasite that invades the blood?
HERMATOZOIC PARASITE
Type of parasite that having male & female reproductive organs in separate individuals?
DIOECIOUS PARASITE
Type of parasite that having male & female reproductive organs in a single individual?
MONOECIOUS/HERMAPHRODITIC PARASITE
Parasite that lives outside the body of the host?
ECTOPARASITE
Parasite that lives inside the body of the host?
ENDOPARASITE
Parasites that are found in its unusual habitat?
ERRATIC PARASITES
Type of host in which the parasite undergoes reproduction to complete it’s cycle and reaches maturity?
DEFINITIVE/FINAL HOST
Type of host that harbors asexual or larval stage of development but does not reach sexual maturity?
INTERMEDIATE HOST
Type of host that harbors the parasite and is actively transmitted to the next host?
RESERVOIR HOST
They are animate or inanimate objects that carries the infective stage of the parasite?
VECTORS
Type of vector that transmits a parasite without being a host, parasite stays in the host but does not undergo development?
MECHANICAL/PHORETIC VECTOR
Type of vector that transmits the parasite only after the parasite completes it’s development within the host
BIOLOGICAL VECTOR
Type of HOST-PARASITE RELATIONSHIP in which either can not exist independently.
SYMBIOSIS
Type of HOST-PARASITE RELATIONSHIP in which one benefits from the other without causing harm.
COMMENSALISM
Type of HOST-PARASITE RELATIONSHIP in which both are benefited yet can exist independently.
MUTUALISM
Type of HOST-PARASITE RELATIONSHIP in which one is entirely dependent on the other that causes harm.
PARASITISM
Invasion of the infective agent in the host.
INFECTION
It is the development and reproduction of parasite on the surface body of the host?
INFESTATION
It harbors a particular pathogen without manifesting any s/sx.
CARRIER
Infection acquired by an individual resulting from their own direct source of re-exposure?
AUTOINFECTION
Individual is infected after being cured and gets reinfected by the same parasite.
REINFECTION
Host is harboring more than one parasite at a time.
SUPERINFECTION/HYPERINFECTION
What are the phases of parasitism? (4)
- Contact and entry to the host
- Migration of parasite to habitat
- Maturation and reproduction
- Exit & development / dissemination
It refers to a dse with low incidence but constantly present in a given community.
ENDEMIC
Refers to the degree of tolerance to a certain pathogen.
ENDEMICITY
Factor that promote endemicity of parasites. (3)
- Presence of a suitable host
- Escape of the parasite from the host
- Environmental conditions that enhances the survival of the parasite outside of the host.
It refers to a dse with high incidence and is constantly present in a given community.
HYPERENDEMIC
It refers to a sharp rise/high mobidity of the dse and is occasionally present in the community.
EPIDEMIC
It refers to a dse that appears occasionally in 1 or some members of a community.
SPORADIC
Refers to the spread of dse that has been disseminated over extensive area of the world?
PANDEMIC
Types of ZOONOSIS
Nemonic: P A A Z E A
PARAZOONOSIS
ANTHROPOZOONOSIS
AMPHIXENOSIS
ZOOANTHROPONOSIS
ENZOONOSIS
ANTHROPONOSIS
Type of zoonosis that is common to man and reservoir.
ENZOONOSIS
Type of zoonosis that is present accidental host?
PARAZOONOSIS
Type of zoonosis that is acquired by man from other vertebrates.
ANTRHOPOZOONOSIS
Type of zoonosis that is common to man and vertebrates.
AMPHIXENOSIS
Type of zoonosis that is transmitted to animals from humans.
ZOOANTHROPONOSIS
Type of zoonosis that exclusive to man but needs to develop elsewhere.
ANTHROPONOSIS
