Coccobacillus

Coccobacillus is the singular of coccobacilli, which are a type of rod shaped bacteria. While still rod shaped, coccobacilli are so short and wide that they resemble cocci. Coccobacillus is derived from the words cocci (spherical shaped) and bacilli (elongated) bacteria. An example would include Haemophilus influenzae.

Acinetobacter strains may grow on solid media as coccobacilli.

Actinobaccilus actinomycetemcomitans/Aggregatibacter actinomycetemcomitans is a gram negative coccobacillus which is prevalent in subgingival plaques.
