True or False
Infection control is intimately embedded in the discipline of microbiology

Microbiology is the study of small life forms, including...

The discipline of microbiology began as a science concerned with

True or False
Bacteria are prokaryotic, unicellular and can live as an individual cell

Bacteria come in different shapes and sizes which include

Cocci (coccus) bacteria are 1 micrometer, single cells or small clusters or chains, and what shape?

Bacilli bacteria are rod shaped, 1micrometer (um)wide and 5-10um long and some form...

Disease's caused by bacilli bacteria are anthrax, botulism, tetnus, and the GI infections

True or False
There are two different shapes of spiral bacteria, Vibrios and spirillum.

Vibrios are what shape

Vibrios are responsible for gastroenteritis, cholera, septicemia and

spirillum or spirilla are what shaped?

spirillum are responsible for

spirochetes are what shape

spirochetes are responsible for leptospirosis, Lyme disease and

Pleomorphic bacteria are morphologically indistinct meaning

True or false
The structure of a bacteria cell changes greatly depending on its shape.

The cytoplasm of a bacterial cells is contained within the cytoplasmic membrane and may contain storage granules of starch, lipids and iron. The cytoplasm may also contain

The cytoplasm of bacteria is viscous and contains water, enzymes, proteins, carbs, lipids, nucleic acids, oxygen, essential nutrients, as well as

Embedded in the cytoplasm is this structure which contains single, long chromosome of DNA that controls most of the cell activities.

These structures which contain extra chromosomal DNA and often carry genes that express resistance to chemical and physical agent is and antibiotics and are only found in some bacteria are known as

The cytoplasmic membrane is composed of lipids and proteins, it surrounds the cytoplasm, contains enzymes that help create the outer wall, and is responsible for maintaining cell pressure, as well as

Mesosomes are found on the inward foldings of cytoplasmic membrane and are found mostly in gram negative or positive bacteria?

The cell wall is a rigid structure that gives the cell its shape. The basic component is peptidoglycan which forms a netting over the entire surface of the cell. Gram-negative bacteria have several layers of peptidoglycan. The cell wall is not present in which type of cells

The outer membrane is found only on gram-negative bacteria and covers the entire surface of the cell. What structure is this outer membrane similar too?

The outer membrane contains endotoxin (composed of lipid, polysaccharides and protein) when the endotoxin is release from the cells is damages nearby cells causing fever, inflammation, bone destruction, hemorrhage and vomiting. The release of endotoxins also plays a role in disease such as

The capsule is found on gram negative and positive bacteria, it contains water (allowing survival in dry conditions), influence cell behavior with other cells and also reduces...

Flagella are long thread-like protein appendages found on some bacteria, its whip like motion allows bacteria to move through fluids. The flagella are attached to what part of the cell
