These strains of C. hominis produced small, shiny, convex colonies visible within a week on first isolation. After further subcultures, colonies were visible within 2 days. Isolation was achieved on blood or chocolate media with added CO2. When examined later the strains did not require CO2, but growth was improved by moisture. They gave a positive oxidase reaction and produced indole, but did not produce catalase or reduce nitrates; this pattern of reactions should serve to distinguish them from strains of Haemophilus aphrophilus, Actinobacillus actinomycetemcomitans and Streptobacillus moniliformis. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-3-1-91
