A Case of Diabetic Mellitus Foot Infection by a Newly Reported Neisseria Skkuensis: Case Report.
In pus and wound samples collected from the right second toe of a 61-year-old woman with diabetes mellitus (DM), gram-negative diplococci bacterium was observed. However, the bacterium could not be identified by conventional microbiological methods and mass spectrometry. In the partial 16S rRNA gene sequence analysis, the bacterium showed a 100% identity match with GenBank sequence FJ0763637.1 (Neisseria skkuensis). N. skkuensis, SMC-A9199 strain, was reported as a novel species in 2010 based on its phenotypic characteristics and the 16S rRNA gene sequence, which was isolated from the blood and wound pus of a DM patient with a foot ulcer. The second reported N. skkuensis was identified from the blood cultures of a patient with endocarditis. To the best of our knowledge, this is only the third report of N. skkuensis.
