The study of bacteria is referred to as
Bacteriology
A non-scientific name for small organisms, such as bacteria, fungi, and viruses that invade the body and cause disease.
Germ
Harmless, non-disease producing bacteria
NONPATHOGENIC
Percent of all bacteria that are nonpathogenic
70%
Live everywhere,
Cause of infection and disease and some produce toxins.
PATHOGENIC
Types of pathogenic bacteria
Cocci, Bacilli, Spirilla
Types of Cocci bacteria
Staphlococci, Streptoccocci, Diplococci
Round - shaped cells, Appear singularly or in groups
Cocci
Forms a bunch or clusters (like grapes),Pus – forming, Found in boils,Cause of staph infection
Staphlococci
Form in long chains,
Pus – forming,
Cause strep throat, blood poisoning, rheumatic fever and more.
Streptoccocci
Round and grow in pairs, Cause pneumonia
Diplococci
Bacteria grow best in…
warm, damp conditions.
Bacteria grow through a growth cycle that consists of…
two stages:
Active
Inactive
Reproduce and Grow Rapidly,
Grow in dark,damp,dirty areas where a food source is available.
Active Bacteria
Condition unfavorable = No Growth,
Form spores not hurt by disinfection, cold or heat.
Inactive Bacteria
How does bacteria move ?
Bacilli and Spirilla have flagella (cilia)
Hair-like projections which extend from the sides of the cell.
Act as propellers to help bacteria travel through air and liquids.
Smaller than bacteria; cause familiar diseases: Cold, Measles, Hepatitis, HIV
Viruses
Caused by pathogenic bacteria or viruses; entering the body and multiplying.
Infection
Can transmit through touch or the air.
Contagious (communicable)
carried through blood or body fluids.
Bloodborn pathogens
Common means of spreading infection in a salon:
Open sores, Unclean hands and implements, Coughing or sneezing, Common use of drinking cups and towels, Use of same implements on infected areas and non-infected areas, Unsanitary salon conditions
Human Hepatitis B; affects liver; may need vaccine
HBV
AIDS; affects natural immunity; body fluids into bloodstream of non-infected.
