Suppurative parotitis caused by anaerobic bacteria in newborns.

Staphylococci are the usual bacterial etiology of suppurative parotitis in newborns. This report describes for the first time recovery of anaerobic bacteria from aspirates of the infected gland in two infants with suppurative parotitis. Peptostreptococcus intermedius and Prevotella melaninogenica were isolated from one child and Prevotella intermedia from the other patient. Complete recovery occurred after 4 weeks of antimicrobial therapy.
