What are the 4 most common 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.
Where is comma bacteria found?
Vibrio is a genus of Gram-negative bacteria, possessing a curved-rod (comma) shape, several species of which can cause foodborne infection, usually associated with eating undercooked seafood. Typically found in salt water, Vibrio species are facultative anaerobes that test positive for oxidase and do not form spores.
Where is Vibrio bacteria found?
Vibriosis is an intestinal disease caused by small bacteria called vibrio. Vibrio are found in fish and shellfish living in saltwater and in rivers and streams where freshwater meets saltwater. Although there are several types of vibrio, Vibrio parahaemolyticus and related species are the most common in the northwest.
What are common shaped bacteria?
There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.
Which type of cell has comma shape?
The most common cell morphologies are cocci (spherical) and bacilli (rods). Coccibacillus are a mix of both, while vibrio are shaped like a comma, spirilla are shaped like a helix (a spiral, sort of like a stretched-out Slinky), and spirochetes are twisted like a screw.
What is the most common shape of bacteria?
Most bacteria come in one of three basic shapes: coccus, rod or bacillus, and spiral.
What are the 3 main bacteria shapes?
Individual bacteria can assume one of three basic shapes: spherical (coccus), rodlike (bacillus), or curved (vibrio, spirillum, or spirochete).

What are the types of bacterial morphology?
There are three basic morphologies of bacteria (based on the shape ofa single cell): bacillus (little rod), coccus (grain or berry) or spirillum(coiled or helical).
