Porphyromonas asaccharolytica is a rare cause of Lemierre's syndrome with only a few cases being reported in the literature [5-7].
Gram-negative anaerobic bacteria from the initial emergency department visit were later identified as Porphyromonas asaccharolytica. Repeat blood cultures did not show growth of any microorganism.
Some other microorganisms associated with Lemierre's syndrome include Streptococcus, Staphylococcus, Eikenella corrodens, Porphyromonas asaccharolytica, and Bacteroides.
