24
Q

free-living organism that passes through the digestive tract without infecting the host.

A

SPURIOUS PARASITE:

25
Q

Parasite that parasitizes another parasite.

A

HYPERPARASITE:

26
Q

Mistaken as parasite.

A

PSEUDOPARASITE:

27
Q

defined as an organism, which harbors the parasite and provides nourishment and shelter to the latter and is relatively larger than the parasite.

A

HOST

28
Q

CLASSIFICATIONS OF HOSTS

A

DEFINITIVE HOSTS
INTERMEDIATE HOSTS
PARATENIC HOSTS
RESERVOIR HOSTS
ACCIDENTAL HOSTS

29
Q

is one in which the parasite obtains sexual maturity.

A

DEFINITIVE HOSTS

30
Q

harbors the asexual or larval stage of the parasite.

A

INTERMEDIATE HOSTS

31
Q

infect the pork tapeworm

A

Taenia solium

32
Q

beef tapeworm

A

Taenia saginata

33
Q

the parasite does not develop further to later stages.

A

PARATENIC HOSTS

34
Q

allow parasite’s life cycle to continue and become an additional source of infection.

A

RESERVOIR HOSTS

35
Q

which the parasite is not usually found.

A

ACCIDENTAL HOSTS

36
Q

prolonged association between two or more different biological species

A

SYMBIOSIS

37
Q

in which two species live together and one species benefits from the relationship without harming or benefiting the other.

A

COMMENSALISM-

38
Q

in which two organisms mutually benefit from each other.

A

MUTUALISM

39
Q

where one organism, the parasite, lives in or on another, depending on the latter for its survival and usually at the expense of the host.

A

PARASITISM

40
Q

2 types of exposure

A

INCUBATION PERIOD
PRE-PATENT PERIOD

41
Q

is the period between infection or acquisition of the parasite and evidence or demonstration of infection.

A

PRE-PATENT PERIOD

42
Q

Is the period between infection and evidence of symptoms.

A

INCUBATION PERIOD

43
Q

2 types of INFECTION

A

AUTOINFECTION
SUPERINFECTION

44
Q

happens when the infected individual is further infected with the same species leading to massive infection with the parasite.

A

SUPERINFECTION

45
Q

results when an infected individual becomes his own direct source of infection.

SOURCES OF INFECTION

A

Contaminated soil and water
Food
