Study Notes

Bacterial Diseases

Bacterial diseases can cause serious or life-threatening conditions, including blood poisoning (bacteremia), kidney failure, and toxic shock syndrome.
Relapsing fever is a louse-borne disease caused by Borrelia recurrentis.

Tuberculosis

There are three types of TB.
Human TB is rarely transmitted to non-humans.

Disinfection and Decontamination

Disinfection is the elimination of microorganisms from inanimate objects or surfaces.
Decontamination is the treatment of an object or inanimate surface to make it safe to handle.

Vertebrates

Vertebrates include amphibians, reptiles, birds, and mammals.
They range in size from the smallest frog species (7.7 mm) to the blue whale (up to 33 m).

Disease Transmission

Indirect contact occurs when coming into contact with areas where animals live and roam.
Vector-borne diseases occur when being bitten by a tick, or an insect.
