Chapter 4-Microbiology for sterile processing technicians

Vegetative stage: 🌱

State of active growth of microorganisms.

Binary Fission: 🦠🦠

The typical method of bacterial reproduction in which a cell divides into two equal parts.

Prion:

-An infectious protein particle

-contains no nucleic acid

-does not trigger an immune response

-is not destroyed by extreme heat or cold.

Contamination:

The state of being soiled by contact with infectious organisms or other materials.

Microbiology:

The study of microorganisms.

Pathogen:

Capable of producing disease

Aerobic:

Requiring the presence of air or free oxygen.

Micron:

1/25,000 of an inch or 1/1000 of a millimeter.

Anaerobic:

Bacteria that can live in the absence of atmospheric oxygen.

Endospores (spores):

Microorganisms capable of forming a thick wall around themselves, enabling them to survive in adverse conditions.

pH:

Measure of alkalinity or acidity on a scale of 0 to 14; pH of 7 is neutral, below 7 is acid, above 7 is alkaline.
