Exam 1 Matching Flashcards
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.
Primary infection
The first time your exposed to a pathogen
Secondary infection
A secondary infection is an infection that occurs during or after treatment of another pre-existing infection.
Centrifugal flotation
When you use a centrifuge and run a flotation of stool mixed with solution
Simple flotation
When you let the fecal stand for 15-20 minutes and let the cells go to the top of the stand and stick to the slide
Sheathets sucrose solution
Coccidial oocysts are easier to see in Sheather’s solution compared to salt solutions, and is made of sugar
Nosocomial infection
is an infection whose development is favored by a hospital environment, such as one acquired by a patient during a hospital visit or one developing among hospital staff.
Epizootic
of, relating to, or denoting a disease that is temporarily prevalent and widespread in an animal population.
Enzootic
is the non-human equivalent of endemic and means, in a broad sense, “belonging to” or “native to”, “characteristic of”, or “prevalent in” a particular geography, race, field, area, or environment; native to an area or scope.
Symptomatic
serving as a symptom or sign, especially of something undesirable.
Asymptomatic
(of a condition or a person) producing or showing no symptoms.
Disease animal
When symptoms are being shown of the disease
Carrier animal
When symptoms are not being shown but can still pass the disease
Age associated immune
They become immune with age
Hypobiosis
Parasite goes into the tissue and hides out, after the medicine comes out of body the parasites come out and become active
Pre-patent period
The time between when an animal is first infected with a parasite and when it starts passing eggs
