The organism is usually nonpathogenic or weakly pathogenic. However, there have been a few reports, mostly in the dental literature, that describe important Eikenella infections. Most were associated with severe trauma, dental manipulation, or a depressed immune system.1,2 Some drug abusers have experienced abscesses after using saliva to liquefy drugs before injection.3In a series of 41 Eikenella isolates obtained at UCLA and Wadsworth Hospital Center, Los Angeles, from 1974 through 1977, there were no isolates from brain abscesses.4 Recently, we have seen a patient with a large brain abscess caused by Eikenella who had no predisposing illness or dental surgery.
