title: Isolation of a variant Porphyromonas sp. from polymicrobial infections in central bearded dragons (Pogona vitticeps).
abstract: Isolates of gram-negative anaerobic bacteria from reptiles have only occasionally been identified to the genus and species level in the veterinary medical literature. In particular, reports identifying Porphyromonas spp. from infections in reptiles are scarce. The present report describes unique Porphyromonas isolates obtained from necrosuppurative infections in central bearded dragons (Pogona vitticeps). The isolates grew in the presence of oxygen, were strongly hemolytic, and did not produce detectable black, iron porphyrin pigment. Biochemical identification kit numeric biocodes gave high but unreliable probabilities (>99.9%) for identification as Porphyromonas gingivalis. Partial 16S ribosomal RNA gene sequences of the isolates were identical to each other and shared 91% identity with those of Porphyromonas gulae. The isolates may represent a new reptile-associated Porphyromonas species.
