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.
