Exam 1 Matching Flashcards
(39 cards)
Reservoir Host
A host that serves as a source of infection and potential reinfection of humans and as a means of sustaining a parasite when it is not infecting humans.
Definitive Host
a host in which the parasite reaches maturity and, if possible, reproduces sexually.
Paratenic Host
An intermediate host whose presence may be required for the completion of a parasite’s life cycle but in which no development of the parasite occurs.
Intermediate Host
the host in which a parasite undergoes development but does not reach sexual maturity.
Vector
Bridge between an infected host and a possible host
Endemic
The amount of disease you expect to see in a population
Zoonosis
A disease that can be transmitted from an animal to a person
Epidemic
a widespread occurrence of an infectious disease in a community at a particular time.
Prevalence
The number infected divided by the population of host
Incidence
the occurrence, rate, or frequency of a disease
Pathogen
is a biological agent that causes disease or illness to its host.
Pathogenicity
is the potential capacity of certain species of microbes or viruses to cause a disease.
Parasitemia
is the quantitative content of parasites in the blood.
Acute infection
invasion and multiplication of microorganisms in body tissues, especially that causing local cellular injury due to competitive metabolism, toxins, intracellular replication or antigen-antibody response.
Chronic infection
A long term infection
Transmammary (lactogenic) transmission
The lactogenic rout, like puppies getting milk from mother
Transplacental transmission
Rout through the uterus
Infective stage larva (L3)
The stage at which larva can infect host
Percutaneous transmission
Rout through the skin
Autoinfection
reinfection with larvae produced by parasitic worms already in the body
Epidemiology
is the science that studies the patterns, causes, and effects of health and disease conditions in defined populations.
Diarrhea
Loose and watery stool
Immunosuppression
Suppression of the immune system and its ability to fight infection.
Inflammation
is a process by which the body’s white blood cells and chemicals protect us from infection with foreign substances, such as bacteria and viruses.
