Terms Used in Parasitology and Infectious Diseases

Parasite 寄生蟲- An organism which is dependent on another

parasitoid organism for its survival.

Host 宿主- An organism which harbours the parasite and is

usually larger than the parasite.

Ectoparasite 外寄生- A parasite which lives on the outside of

the host.

Endoparasite 內寄生- A parasite which lives within the body

of the host..


Facultative parasite 兼性寄生- A parasite which capable of

living both freely and as a parasite.

Obligate parasite 絕對寄生- A parasite which is completely

dependent upon the host.

Commensal片利共生- A parasite which does not damage the


Symbiont共生物- A parasite which contributes to the

welfare of the host.

Symbiosis 共生作用- A situation in which host-parasite

relationship results in advantages rather than


Pathogen 病原- A parasite which is able to produce


Pathogenicity 致病性-Is the ability of a parasite to produce


Virulence 致病毒力- Refers to the degree of pathogenicity.

Reservior host 儲備宿主- Where the parasite is

maintained in nature and which acts as a source for

individual new cases.

Intermediate host中間宿主- A host in which the

intermediate stages of the parasite develop.

Definitive host 終宿主- A host in which the definitive or

the final stages of the parasite.

Paratenic host 保幼宿主- A host which acts as a

transporting agent for the parasite and in which

the parasite does not undergo any development.

Infection 感染- Means the presence of a parasite in or on

the tissues of a host. Such colonization may or may

not have a deleterious effect on the host.

Disease 疾病- If parasite has a deleterious effect on the


Infestation 侵染,感染- The presence of arthropods on the

skin of the host.

Epidemic 流行性- The sudden appearance of an infection

which spreads rapidly and involves large population.

Endemic 地方性,本土性- An infection which has always

existed in a region.

Pandemic 全球性– A widespread epidemic, usually of

world-wide proportion. These are mainly viral diseases.

Incubation 潛伏期– The time between the entrance of a

parasite into a host and the beginning of the disease.

Habitat 棲所– The natural abode of a parasite species.

Ecology 生態– The relationship between a population of

an organism and the environment. When this is a

balanced relationship the host remains healthy.

Disease is manifested when this relationship breaks down.

Zoonosis 人畜共通疾病– Diseases of animals which are

transmissible to man.

Anthroponosis 人畜共通疾病-Diseases of man which are

transmissible to animals.

Incidence 發生率– Is a number of new cases occurring

within a given period of time, often expressed as the

number per 100,000 people per year.

Prevalence 盛行率– Is the proportion of people who have

the disease at a certain time in a designated area.

Opportunistic parasites or infections 伺機性寄生蟲或感染–

Parasites which are not normally pathogens but

become so due to impairment of host resistance.

These are assuming increasing clinical importance

because of the AIDS epidemic.

Morbidity 致病(罹患)率– Incidence of disease in a given

population, including both nonfatal and fatal cases.

Mortality死亡率– Incidence of death in a given population.

In vivo體內– In the body, in a living organism.

In vitro體外– In culture medium.

Monoxenous species– parasite fully develop in one host

Heteroxenous species– parasite development more than one


Cell-mediated immunity細胞中介免疫– An immune

response generated by the activities of non-antibody

producing cells.

Humoral immunity體液免疫– An immune response due

to the activities of antibodies.

Active immunity主動免疫– An immune state achieved

by self production of antibodies.

Passive immunity被動免疫– An immune state resulting

from transfer of antibodies from an immune to a non

immune individual.
