The bacteria causing the thrombophlebitis are anaerobic bacteria that are typically normal components of the microorganisms that inhabit the mouth and throat. Species of Fusobacterium, specifically Fusobacterium necrophorum, are most commonly the causative bacteria, but various bacteria have been implicated. One 1989 study found that 81% of<unk>  had been infected with Fusobacterium necrophorum, while 11% were caused by other Fusobacterium species. MRSA might also be an issue in<unk>  infections. Rarely<unk>  is caused by other (usually Gram-negative) bacteria, which include Bacteroides fragilis and Bacteroides melaninogenicus, Peptostreptococcus spp., Streptococcus microaerophile, Staphylococcus aureus, Streptococcus pyogenes, and Eikenella corrodens.
