Abstract

sp. strain GNAT3597 was isolated from the biting midge genus (Diptera: Ceratopogonidae). It was serologically distinct from other species, groups or subgroups. Dark-field microscopy of the cells revealed the classical helical shape and subsequent transmission electron microscopy revealed cells surrounded by only a cell membrane (i.e. lacking a cell wall). Growth of strain GNAT3597 occurred in M1D medium at 30 °C. Strain GNAT3597 catabolized both glucose and arginine, but did not hydrolyse urea. The DNA G+C content of strain GNAT3597 was 29±1 mol%. Only one strain, SMCA (), is serologically related to strain GNAT3597, although the relationship is weak (positive reaction to only a 1 : 80 dilution). It is therefore proposed that strain GNAT3597 (=ATCC BAA-520=NBRC 100390) represents a novel species, sp. nov. (class : order : family ).
