What are the main shapes of bacteria?
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.
How do you identify bacteria?
Bacteria are identified routinely by morphological and biochemical tests , supplemented as needed by specialized tests such as serotyping and antibiotic inhibition patterns. Newer molecular techniques permit species to be identified by their genetic sequences, sometimes directly from the clinical specimen.

What is the shape of streptococci bacteria?
Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains.
What is Vibrio shape?
Vibrio parahaemolyticus is a Gram- negative straight or curved rod-shaped facultative anaerobic bacterium, which is motile by means of a single polar flagellum.
What are round shaped bacteria called?
External Websites. Coccus , plural Cocci, in microbiology, a spherical-shaped bacterium. Many species of bacteria have characteristic arrangements that are useful in identification.

- 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.
What three basic shapes of bacteria can be seen in a simple stain?
The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted) , however pleomorphic bacteria can assume several shapes. Cocci (or coccus for a single cell) are round cells, sometimes slightly flattened when they are adjacent to one another.

What are the 2 main types of bacteria?
There are broadly speaking two different types of cell wall in bacteria, that classify bacteria into Gram-positive bacteria and Gram-negative bacteria .
How many type of bacteria are there?
How Many Named Species of Bacteria are There? There are about 30,000 formally named species that are in pure culture and for which the physiology has been investigated. Species now are being defined by PCR amplifying ribosomal genes and sequencing.
