the science that studies living organisms that cannot be seen with the naked eye.
Pathogen
a disease-producing microorganism
Aerobic microbes
microbes that can only live in the presence of oxygen
Anaerobic microbes
Microbes that grow best in the absence of oxygen
Antiseptics
Solutions that are applied directly to the skin and prevent or slow the growth of pathogens.
Disinfection
A process that uses strong chemicals such as bleach solution and zephirin to kill pathogens. These chemicals are used mainly on objects and not on the skin.
Sterilization
A process used to kill microbes and their spores.
Bacteria
single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission
Fungi
plant like organism that lives on dead matter
Protozoa
tiny animals that are found in contaminated water supplies and in decayed materials
Rickettsiae
parasites that must live inside the cells of other living organisms. They are transmitted by the animal the parasites inhabits, such as fleas, lice, and ticks.
Viruses
the smallest of all the microorganisms. They can grow and reproduce only inside other living cells, and are difficult to destroy
non-pathogen
microbes that benefit humans and the environment
Cocci
round in shape
bacilli
rod shaped
spririlla
corkscrew or spiral shaped
diplococci
cocci occur in pairs or two circles
streptococci
cocci occur in chains
staphylococci
cocci occur in clusters or groups
flagella
threadlike projections similar to a tail that allow the organism to move
spores
thick walled capsules, occurs when conditions are poor,
antibiotic resistant
bacterium that is resistant to antibiotics
antifungal medications
used to treat fungal infections, can cause liver disease
antibiotics
used to kill bacteria, ineffective against viruses
Hepatitis B
Virus that is transmitted through blood and body fluids that causes serious liver disease, there is a vaccine available and employers must provide the vaccine to employees
Hepatitis C
Virus that causes liver disease that is spread through blood and body fluids, there is no immunization for this virus
Acquired Immunodeficiency Syndrome (AIDS)
this virus suppresses the immune system, individuals can not fight off many cancers and infections that would not affect a health person. There is no immunization.
helminths
multicellular parasitic organisms commonly called worms or flukes
Hookworms
attach to the small intestine and can infect the heart and lungs
Taenia solium (pork tapeworm)
contracted by eating inadequately cooked pork
