1. Virulence

The extent of pathogenicity is called virulence of a pathogen.

2. Name the three subgroups of spiral bacteria

These are curved shaped bacteria. They are further divided into 3 more subgroups. a. Vibrio: curved rods b. Spirillum: Helical but rigid c. Spirochete: Helical but flexible Spirochetes move by axial filaments which are enclosed by the outer membrane

3. flagellm and function (2

Flagellum: Long filamentous structure that propels bacteria It helps the bacteria in movement.

Q4. Name the Types of Bacteria on the basis of Oxygen Requirement

1. Obligate Aerobes: Do not grow without oxygen. It is necessary.
2. Facultative Anaerobes: Oxygen is necessary but start become anaerobes in its absence and can grow without of O2.
3. Obligate Anaerobes: Cannot grow in the presence of oxygen.
4. Aerotolerant aerobes: Do not need O2, also do not bother its presence e. Microaerophiles: Aerobes but need small amount of oxygen. Cannot grow if available in large amount.
