Coccobacilli are therefore in essence very short rods which may be mistaken for cocci. Haemophilus influenzae, Gardnerella vaginalis, 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. Bacteria from the Brucellae genus are medically important coccobacilli that cause brucellosis.
Cocci that divide in multiple planes and form grape like clusters or sheets are called staphylococci. Bacilli. Since bacilli only divide across their short axis there are fewer groupings. Bacillus is a shape (rod shaped) but there is also a genus of bacteria with the name Bacillus.ost bacteria are 0.2 um in diameter and 2-8 um in length. The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes.
