Lecture 1 - Madore Flashcards
Etiology
Study of the cause of disease
Pathology
Study of disease
Idiopathic
Etiology unknown
Acute
A severe sudden onset
Chronic
Milder long lasting - for years or a lifetime
Microorganism
Microscopic organism that are pathogens of disease. Only seen under a microscope.
Pathogen
Microorganism or substance that causes a disease
Pathogenicity
Ability to cause disease - the dose of the pathogen
Carrier
One who carries a microorganism within; the person may or may not be infected
Vector
An insect or animal that serves as an intermediary transporter of a pathogen. Commonly referred to as an insect
Fomite
Non-living transport of virus such as a pen, broken glass, doorknobs, etc
Communicable disease
Infection that is spread from one person to another
Symbiosis
Relationship between two species
Parasitism
One organism is harmed, the other benefits
Commensalism
One organism harmed very little or not at all and the other is provided with shelter and food
Mutualism
Both benefit (ie normal GI bacteria)
Exogenous
Food, water, air, fomites
Endogenous
In or on the bidy
Host
Organism providing food and shelter
Nocosomial
A pathology that is acquired in a hospital or health facility
Iatrogenic
Pathology that is a direct result of treatment, medication, a procedure or error administered by a doctor, nurse, mid-level practitioner
Virulent
Highly infectious and has the ability to cause acute disease. This can be cause by mutations of the agent
Mutations
Process by which a gene or chromosome structurally changes in an attempt to improve the likelihood of its survival
Predisposing factors
Due to genetics of an individual, they may be more susceptible to the development of a disease.
Epidemic
High number of infectious disease within a given area
Pandemic
A disease that occurs on more than one continent
Endemic
Infections that consistently reoccur in a population of a certain area
Epidemiology
The study of tracking the pattern and occurence of disease
Incident
Indicates the number of new cases noted within a stated time period
Morbidity
Indicates the type of disease and rates of disease within a specific age group or septic is group
