Microbiology
Microorganisms are also called _____ & _______.
microbes and germs
Study of parasites, their hosts and the relationship between them.
Parasitology
Eliminating germs on hands
Handwashing
Organisms that feed off the hosts without contributing anything.
Parasites
Two major categories of Microbes
- Acellular infectious organism
- Cellular-Microorganims
(prokaryotes and eukaryotes)
Study of bacteria
Bacteriology
Study of viruses and viral diseases
Virology
Study of fungi and their genetic make up
Mycology
Study of protozoas; branch of zoology
Protozoology
Microbes that live on and in the human body. These are beneficial for the body.
Indigenous Microbiota/ Transient Microbes
Where can we find transient microbes?(3 pts.)
- Skin
- Mouth
- Intestinal tract
Do not cause disease under ordinary conditions but have the potential to cause a disease should the opportunity present itself.
Opportunistic pathogens
Disease causing microbes are called _______.
pathogens
Microbes that do not cause diseases are called ________.
non-pathogens
Capable to cause a disease
Pathogenicity
Where can we find E-coli?
intestinal tract

urinary bladder, blood stream, or wound
Other opportunistic infection strikes when a person becomes;
- rundown/weak
- stressed out
- debilitated
