PHMP MID 2 Flashcards
bacteria that are resistant to several
antibiotics.
Superbugs
when two organisms live intimately close,
typically over longer periods, often measured in
generations for at least one of the organisms.
Symbiosis
prevention of harmful bacterial growth by a non
harmful bacteria.
Microbial competition
present only under unusual
circumstances and only transiently present (hours to
months).
Transient microbiota
Resident microflora are the more-or-less permanent members of normal microflora.
Resident microbiota
Study of disease a Concerned with etiology as well as structural and functional changes brought about by the disease.
Pathology
Occurs when an infection results in any change from a state of health. An abnormal state in which part or all of the body is incapable of performing normal functions.
Disease
An organism’s capacity to cause disease.
Pathogenicity
The degree of disease an organism has the potential to cause disease.
Virulence
These are the ways to enter the host. Microbes can’t cause disease unless they enter the body through the right opening.
Portal of Entry
Respiratory tract (RT), Gastrointestinal tract (GIT), Urogenital tract (UT), conjunctiva
Mucous membranes
unbroken, impenetrable to most people.
Can gain access through hair follicles, sweat
ducts, abrasions
Skin
deposited directly into tissues
beneath skin a Punctures, injections, cuts,
wounds, surgery, cracking
Parenteral route
The period during which the disease is spread is
dependent upon the infecting organism.
Stages of Disease
A combination of signs and symptoms that are
characteristic of a disease.
Syndrome
is a characteristic of a disease that can be felt
(by the individual with the disease) but cannot be
measured by another individual.
Symptom
is a characteristic
of a disease that can be measured by another individual
Sign
Time interval between the initial infection and the
first appearance of any signs or symptoms.
- The time an infection has begun up to the
occurrence of signs and symptoms.
Incubation period
Short period that follows the period of incubation
in some diseases when symptoms (and signs)
appear, but full blown illness has not-yet begun
- Early, mild symptoms
Prodromal period
The phase during which the typical signs and
symptoms of the disease are apparent.
Most acute stage of the illness c] Number of white
cells increases or decreases
Peak of Illness
Period of Illness
period during which the signs and symptoms
subside as the infection is brought
Period of Decline
Person regains strength and the body returns to
its pre diseased state aSequelae are persisting
disease after infection
Period of Convalescence
