(jēnŭs, jen'ĕr-ă), A genus name begins with a capital letter and is printed in italic type: Escherichia, Helicobacter, Staphylococcus. In this form it is never pluralized. When used as a common noun, a genus name begins with a lowercase letter, is not italicized, and may form a plural: chlamydia, staphylococci. A genus name may be abbreviated with or without a period (E. coli, H. pylori, S aureus) only when the meaning is clear from the context.
In natural history classification, the taxonomic level of division between the family, or tribe, and the species; a group of species alike in the broad features of their organization but different in detail, and incapable of fertile mating.
