How are bacteria classified on the basis of flagellum?
Based on their arrangement, bacteria are classified into four groups: monotrichous (having one flagellum), amphitrichous (single flagellum at both ends), lophotrichous (numerous flagella as a tuft), and peritrichous (flagella distributed all over the cell except at the poles).
Is the example of the class Flagellata?
Examples of Flagellata include Trypanosoma, Leishmania etc.
What are the types of flagellates?
Trypanosoma brucei
DictyochalesBicosoecidaPedinellales
Flagellate/Representative species
What are the types of bacteria based from the rings of the flagella?
On the basis of flagella, bacteria may be (Schulz & Jorgensen; 2001) monotrichous, lophotrichous, peritrichous, and amphitrichous (Fig. 7.9). Figure 7.9. Different arrangements of flagella in bacteria (monotrichous (A), lophotrichous (B), peritrichous (C), amphitrichous (D)).
What are 3 different ways to classify bacteria?
Bacteria are classified based on three major groupings: their stain on a Gram test, their shape, and their dependence on oxygen.
How are bacteria classified on the basis of morphology?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
Are flagellates and dinoflagellates the same?
A flagellate is a cell or organism with one or more whip-like appendages called flagella. However, the term “flagellate” is included in other terms (such as “dinoflagellate” and “choanoflagellata”) which are more formally characterized.
What are the two major groups of flagellates?
The heterotrophic flagellates are differentiated into two general groups on the basis of size: (a) heterotrophic nanoflagellates (HNF) below 15 μm and (b) large heterotrophic flagellates within a range of ≥15–200 μm (Arndt et al., 2000).
What is flagella and describe different types of flagellation in bacteria?
Bacterial flagella are helically shaped structures containing the protein flagellin. The base of the flagellum (the hook) near the cell surface is attached to the basal body enclosed in the cell envelope. The flagellum rotates in a clockwise or counterclockwise direction, in a motion similar to that of a propeller.
What is fimbriae microbiology?
Fimbriae are long filamentous polymeric protein structures located at the surface of bacterial cells. They enable the bacteria to bind to specific receptor structures and thereby to colonise specific surfaces.
What are the 4 ways we classify bacteria?
By combining morphology and Gram-staining, most bacteria can be classified as belonging to one of four groups (Gram-positive cocci, Gram-positive bacilli, Gram-negative cocci, and Gram-negative bacilli).
