Coccobacillus

Coccobacillus
Coxiella burnetii

A coccobacillus (plural coccobacilli) is a type of rod-shaped bacteria. The word coccobacillus reflects an intermediate shape between coccus (spherical) and bacillus (elongated).[1] Coccobacilli rods are so short and wide that they resemble cocci. Haemophilus influenzae and Chlamydia trachomatis are coccobacilli. Aggregatibacter actinomycetemcomitans is a gram-negative coccobacillus that is prevalent in subgingival plaques. Acinetobacter strains may grow on solid media as coccobacilli. Bordetella pertussis is a gram-negative coccobacillus responsible for causing whooping cough.

Coxiella burnetti is also a coccobacillus.[2]

Bacteria from the Brucellae genus are medically important coccobacilli that cause brucellosis.

Haemophilus ducreyi is another medically important gram-negative coccobacillus and is observed in sexually transmitted disease, chancroid, of third-world countries.[3]
