Microorganisms that live on the skin, in the nasopharynx, in the gastrointestinal (GI) tract, and on other body surfaces.
a nonspecific chemical inhibitor that is secreted by body blood cells in response to viral invasion.
polymorphonuclear cells that contain granules of digestive enzymes. Specific types of granulocytes include neutrophils, eosinophils, and basophils.
are mononuclear cells that lack digestive enzymes. Monocytes, which are immature macrophages and lymphocytes, are examples of agranulocytes.
a nonspecific chemical inhibitor that is secreted by body cells in response to viral invasion.
foreign particles, such as microbes, that enter a host.
B lymphocytes provide humoral immunity by producing these to convey specific resistance to many bacterial and viral infections.
A series of proteins found in the bloodstream, also aids in the antigen-antibody reaction.
The process of injecting weakened or killed organisms into a person, stimulating antibody production.
toxic substance bound to the bacterial cell wall and released when the bacterium ruptures or disintegrates.
organisms requiring reduced oxygen for growth, are often associated with serious infections.
a new kind of infection caused by an organism different from an initially infecting organism and usually resistant to treatment.
the introduction of microorganisms onto a body surface where they grown and multiply but do not invade the body or cause an immune response or symptoms.
Term used to describe bacteria that are spread through the bloodstream.
Often used as a synonym of bacterimia, but more accurately refers to the presence of microorganisms in the bloodstream which are disrupting normal body functions.
Presence of infectious agents such as Staph or Streppe in the blood.
When a causative agent of a disease is transmissible to between one person and another.
Phase of Febrile Episode in which the body's heat-producing mechanisms attempt to increase the core body temperature. Client experiences cold and shivers; goosebumps may appear; the client's skin appears cool and pale because of vasoconstriction.
Phase of Febrile Episode in which the fever reaches a new, higher set point. The skin appears warm and flush because of vasodilation. Complaints of general malaise occur. High fever may cause delirium or convulsions secondary to cerebral nerve damage.
"Crisis" Phase (third phase) in which the client experiences profuse diaphoresis, decreased shivering, and possible volume deficit. Skin flushed and warm because of vasodilation.
Containing pus, usually thicker than normal, and is often foul smelling because it contains a great deal of cellular debris from the inflammatory response.
When the WBC count is above normal. Normal adult ranges are 5,000 to 10,000 cells/mm3(cubed).
is present and poses a significant risk for infections when the absolute neutrophil count (ANC) falls to fewer than 1000 cells/mm3.
