Unit 7 Lilley Chpt 38

having or pertaining to the ability to destroy or interfere with the development of a living organism. The term is used most commonly to refer to antibacterial drugs

one of two types of tropical antimicrobial agent; a chemical that inhibits the growth and reproduction of microorganisms without necessarily killing them. It is also known as static agents

antibiotics that kill bacteria

Antibiotics that do not actually kill bacteria but rather inhibit their growth

the designation for a broad, major class of antibiotics that includes four subclasses: penicillin, cephalosporins, carbapenems, and monobactams; so named because of the beta-lactam ring that is part of the chemical structure of all drugs in this class

any of a group of enzymes produced by bacteria that catalyze the chemical opening of the crucial beta-lactam ring structures in beta-lactam antibiotics

medications combined with certain penicillin drugs to block the effect of beta-lactamase enzymes

the establishment and growth of microorganisms on the skin, open wounds, or mucous membranes, or in secretions without causing adverse clinical signs or symptoms

An infection that is acquired by persons who have not been hospitalized or had a medical procedure recently (within the past year)

The administration of antibiotics based on known results of culture and sensitivity testing identifying the pathogen causing infection

one of two types of tropical antimicrobial agent; a chemical applied to nonliving objects to kill microorganisms. Also called cidal agents

the administration of antibiotics based on practitioner’s judgment of the pathogens most likely to be causing an apparent infection; it involves the
presumptive treatment of an infection to avoid treatment delay before specific culture information has been obtain

An inheritied disorder in which the red blood
cells are partially or complete deficient in glucose-6 phosphate dehydrogenase, a creitcal enzyme in the metabolism of glucose. Certain medications can cause hemolytic anemia in patients with this disorder. This is an example of a host factor related to drug therapy

An infection that is acquired during the course of receiving treatment for another condition in the health care facility. The infection is not present or incubating at the time of admission

Factors that are unique to the body of a particular patient that affect the patient’s susceptibility to infection and response to various antibiotic drugs

invasions and multiplications of microorganisms in body tissues

Microscopic living organisms (also called microbes)

Antibiotics taken before anticipated exposure to an
infectious organism in an effort to prevent the development of infection

A necrotizing inflammatory bowel condition that is often associated with antibiotic therapy. A more general term that is also used is antibiotic associated colitis

A common genetic host factor in which the rate of metabolism of certain drugs is reduced

referring to antibiotic treatment that is ineffective in treating a given infection. Possible causes include
inappropriate drug therapy, insufficient drug dosing, and bacterial drug resistance

(1) An infection occurring during antimicrobial treatment for another infection, resulting from overgrowth of an organism not susceptible to the
antibiotic used.
(2) A secondary microbial infection that occurs in addition to an earlier primary infection, often due to weakening of the patient’s immune system function by the first infection

Substances that can interfere with normal prenatal development and cause one or more developmental abnormalities in the fetus

Referring to antibiotic therapy that result in sufficient concentrations of the drug in the blood or other tissue to render it effective against specific bacterial pathogens
