A genus is a taxonomic category ranking used in biological classification that is below family and above species. Species exhibiting similar characteristics comprise a genus.

How many classifications of bacteria are there?

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. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

How are bacteria classified into genus?

Taxonomic Systems Bacterial taxonomy is the rank-based classification of bacteria. In the scientific classification established by Carl von Linné, each distinct species is assigned to a genus using a two-part binary name (for example, Homo sapiens).

There are four common forms of bacteria-coccus,bacillus,spirillum and vibrio.

  • Coccus form:- These are spherical bacteria.
  • Bacillus form:- These are rod-shaped bacteria.
  • Spirilla form:- These are spiral-shaped bacteria that occur singly.
  • Vibrio form:- These are comma-shaped bacteria.
