CH. 4 Microbiology BSP

acquired immunodeficiency syndrome AIDS the onset of life-threatening illnesses that compromise the immune system as a result of the HIV infection and disease
acquired immunity an immunity that the body develops after it overcomes a disease or through inoculation.
active (vegetative) stage the stage in which bacteria grow and reproduce
aseptic free of disease and germs
bacilli rod-shaped bacteria that produce disease such as tetanus, typhoid fever, tuberculosis, and diohtheria
bacteria one-celled microorganisms, also known as germs or microbes
bloodborne pathogens disease causing bacteria or viruses that are carried through the body in the blood or body fluids
cocci round-shaped bacteria that appears singly or in grooups
contagious (communicable) a disease that may be transmitted by contact
diplococci round-shaped bacteria that cause diseases such as pneumonia
flagella hair-like extensions that propel bacteria through liquid
fungi plant parasites such as molds, mildew, yeasts, and rusts that can cause ringworm and favus.
general infection an infection that results when the bloodstream carries bacteria or viruses to all parts of the body
hepatitis a bloodborne disease marked by inflammation of the liver
human disease carrier a person who is immune to a disease, but harbors germs that can infect others
human immunodeficiency virus (HIV) the virus that causes AIDS
immunity the ability of the body to resist invasion by bacteria and to destroy bacteria once they have entered the body
inactive stage the stage in which bacteria do not grow or reproduce
infection the result when the body is unable to cope with the invasion of bacteria and their harmful toxins
local infection an infection that is limited to a specific area of the body
mitosis the division of cells during reproduction
MRSA acronym for methicilln-resistant; Staphylococcus aureus, a type of staph infection resistant to certain antibiotics.
natural immunity natural resistance to disease that is partially inherited and partially developed
nonpathogenic beneficial or harmless bacteria that perform many useful function
objective symptoms symptoms that can be seen by anyone
parasites plant or animal organisms that live on other living organisms without giving anything in return
pathogen harmful, disease-producing bacteria
pediculosis a contagious infestation caused by the head or body louse
pus a fluid that contains white blood cells, dead and living bacteria, waste matter, tissue elements, and body cells, a sign of infection
scabies a contagious disorder caused by the itch mite
sepis a poisoned state caused by the absorption of pathogenic microorganisms into the bloodstream
spirilla curved or corkscrew-shaped bacteria that can cause syphilis and Lyme disease
spore-forming bacteria certain bacteria that have the ability to form protective spores to survive an inactive stage
staphylococci pus-forming bacteria that cause abscesses, pustules, pimples, and boils
streptococci pus-forming bacteria that cause infections such as strep throat, tonsillitis, other lung and throat diseases, and blood poisoning
subjective syptoms symptoms that can be felt or experienced only by the person infected
virus an infectious agent that lives only by penetrating cells and becoming a part of them.
What are bacteria? One-celled microorganisms also known as germs or microbes
What are two types of bacteria? Nonpathogenic, which are benefi cial or harmless bacteria that perform many useful functions; and pathogenic, which are harmful, disease-producing bacteria
What are three forms of pathogenic bacteria and what are their shapes? Cocci-round; Bacillli-rod-shaped; Spirilla-spiral/corkscrew-shaped
How do bacteria move about? By means of hair-like projections called flagella or cilia
How do bacteria multiply? By dividing in half through a process called mitosis
What are the characteristics of the active stage of bacteria? It is also known as the vegetative stage and is the reproduction stage of bacteria.
What are the characteristics of the inactive stage of bacteria? The stage in which bacteria do not grow or reproduce. Some bacteria lie dormant and others die off.
What are two types of pathogenic bacteria that can form spores? Anthrax and tetanus bacilli
What is the name of the most common pus-forming human bacteria? Staphylococci
How can infections be controlled or prevented? Through personal hygiene, effective sanitation, and public-sanitation procedures.
What is a local infection? An infection in one spot or area of the body
What is a general infection? One that carries pathogenic bacteria through the bloodstream to all parts of the body
What are the differences between bacteria and viruses? Bacteria are organisms that can live on their own; viruses live only by penetrating cells and becoming a part of them.
What is the definition of natural immunity? Acquired immunity? Natural immunity is a natural resistance to disease that is partially inherited and partially developed through hygienic living; acquired immunity is developed after the body has overcome a disease or through inoculations.
Why is hepatitis more easily contracted than HIV? Because it is present in all body fluids
What is the name of the virus that causes AIDS? Human immunodeficiency virus (HIV)
What is AIDS? It is the onset of life-threatening illnesses that compromise the immune system as a result of HIV infection and disease.
What are some methods that can be used to destroy bacteria Disinfectants, intense heat (boiling, steaming, baking, or burning), and ultraviolet-rays
Identify the type of bacteria that causes MRSA. Staphylococcus aureus
Why might a MRSA infection be difficult to cure? Because it is is resistant to antibiotics such as methicillin, oxacillin, amoxicillin, and penicillin.
How might bloodborne pathogens be transmitted during barbering services? Through contaminated tools or implements that have come into contact with infected blood or body fluids, and through blood-to-blood contact.
Name two types of parasites and the conditions they cause. Plant parasites or fungi produce contagious skin diseases such as ringworm or favus. Animal parasites cause contagious infestations like scabies (itch mite) and pediculosis (lice).
What is a contagious or communicable disease? A disease that can be spread from one person to another by contact.
