Bacteria of the genus Prophyromonas comprise 16 species [3] with P. pogonae as the most recent member [4]. The strain is a Gram-negative coccobacillus, which has the ability to grow underanaerobic and microaerophilic conditions. Furthermore, it shows a strong b-hemolytic activity and is positive for catalase [4]. Fromthe seven isolates described one stemmed from a human suffering fromsinusitiswhilst six isolateswere isolated fromlizards. A recent P. pogonae infection has been reported [3]. The strain was detected in an extended wound of a 31 year old patient after severe trauma. However, the patient did not develop sepsis [3]. Porphyromonas spp. are well established causes of dental infections, but are also linked to venous diseases and rheumatoid arthritis [5,6]. The most widely studied species is P. gingivalis, which has also been reported to cause bacteremia and sepsis [7e9].Both P. pogonae and P. gingivalis grow under anaerobic and microaerophilic conditions and therefore theymay be distributed in a similarway [3]. Ability of P. pogonae to grow under microaerophilic conditions was confirmed by growing the strain using CampiGen gas generating sachets (ThermoFisher Scientific). After 24 h incubation at 37 Cin an anaerobic jar bacteria grew strongly on HCB agar, comparable to anaerobic growth conditions. Grownmicroorganisms were verified as P. pogonae using MADLI-TOF MS (Score: 2.436). Furthermore, when incubated aerobically at 37 C for 24 h, P. pogonae grew weakly on Colombia blood agar. Again, bacteria could be verified by MALDI-TOF MS as P. pogonae (Score: 2.484).
