Chapter 4 Flashcards
Study of small living organisms called microbes
Microbiology
Dirty
Contaminated
Germs or microbes, are one-celled, microorganisms
Bacteria
Disease producing bacteria
Pathogenic
Nondisease-producing bacteria
Nonpathogenic
Nonpathogenic bacteria that live on dead matter
Saprophytes
The study of bacteria
Bacteriology
Spherical or round-shaped bacterial cells, which appear singularly or in groups
Cocci
Pus-forming bacterial cells that for grape-like bunches or clusters and are present in abscesses,pustules, and boils.
Staphylococci
Pus forming,form in long chains, can cause septicemia
Streptococci
Grow in pairs, can cause infections such as pneumonia
Diplococci
Most common bacterial cell, bar/rod shaped, produce a variety of diseases (tetanus, bacterial influenza, typhoid fever,tuberculosis and diptheria)
Bacilla
Spiraled, coiled, corkscrew shaped; cause highly contagious diseases such as syphilis and cholera
Spirilla
Vegetative state, bacteria reproduce and grow rapidly
Active stage
Unfavorable conditions, cells die or become inactive
Inactive stage
Hair-like projections that move the cells using a wave-like motion
Flagella
Hair-like projections, found in the cells, used to move cells with a wave-like motion
Cillia
Sub-microscopic infectious agent that replicates itself only within cells of living hosts
Virus
Personal service workers; information released to estheticians by cdc
PSW
Highly infectious disease that affects the liver
HBV
Life-threatening viral disease
HIV
Highly infectious disease caused by HIV, interferes with the body’s natural immune system and causes it to break down
AIDS
Organisms that feed and grow on other living organisms, contribute nothing to their host and cause contagious diseases
External parasites
Growth of a parasitic organism within the body
