study of the cause of disease
development of disease
invasion of the body by a pathogenic organism
Any change, other than an injury, that disrupts the normal functions of the body.
the organism that a parasite or virus lives in or on
time between infection and appearance of first symptoms or signs of disease
Microorganisms that reside in or on the body without causing disease
present for only a short period of time
the degree or extent of pathogenicity of an organsim, may affect portal of entry and number of organisms.
An organism that causes disease
Doesn't cause disease in healthy individuals, under certain conditions can cause disease. Exs: yeast infection - Candida albicans.
When normal microbes benefit the host by preventing the overgrowth of harmful microbes.
symbiotic relationship in which one member of the association benefits and the other is neither helped nor harmed
a symbiotic relationship in which both species benefit
A relationship between two organisms of different species where one benefits and the other is harmed
disease caused by a pathogen about 1/2 humans disease is this type.
any disease that can be spread spread from one host to another directly or indirectly.
a disease that cannot be spread from person to person
A disease that is easily spread from one host to another
develops rapidbly but lasts a short time (eg flu, RSF)
A disease that developes slowly but the disease may be continual for a long time.
Intermediate between acute and chronic
any disease in which a pathogen remains inactive for a long period of time before becoming active. EX. cold sore.
Disease constantly present in a population
when many people in a given area acquire a certain disease in a relatively short period of time
an infection confined to a specific area of the body. Ex boils, pimples
an infection that does not cause a noticeable illness; also called "Inapparent Infection"
THE PRESENCE OF BACTERIA IN THE BLOOD. Not multiplying
Bacteria multiplying in the blood.
Toxins in the blood
Viruses in the blood
storage areas for living or non living microbes =. provide good conditions for survival.
Hospital acquired infections
changes in body that are not measurable. Ex. pain
changes that can be observed and measured. Ex. Fever
a group of symptoms or signs always accompany a disease. EX., TSS
when and where diseases occur and how they are transmitted to in human population.
any object that harbors and transmitts pathogens. Ex. door knob
a relationship between two species in which both species benefit
incidence of a specific notifiable disease
Deaths from these diseases
