| Grahamella | <bacteria> A genus of aerobic, nonmotile microorganisms (order Rickettsiales) containing long or short, rod-shaped, Gram-negative cells which resemble those of Bartonella but which are less pleomorphic. These organisms occur within the erythrocytes of lower mammals, but they appear to be nonpathogenic and do not affect the health of the host. Origin: G. S. Graham-Smith (05 Mar 2000) |
