Spiroplasma mirum, a New Species from the Rabbit Tick (Haemaphysalis leporispalustris) TULLY, JOSEPH G. and WHITCOMB, ROBERT F. and ROSE, DAVID L. and BOVÉ, JOSEPH M.,, 32, 92-100 (1982), doi = https://doi.org/10.1099/00207713-32-1-92, publicationName = Microbiology Society, issn = 1466-5026, abstract= Three spiroplasma strains recovered from rabbit ticks (Haemaphysalis leporispalustris) in Georgia and Maryland were found to be similar in biochemical, serological, and pathological properties. The organisms grew at temperatures of 20 to 37°C, required cholesterol for growth, fermented glucose, hydrolyzed arginine, and produced a film and spot reaction. The three spiroplasma strains were serologically distinct from the one established species (Spiroplasma citri) in the genus and from all other unclassified spiroplasma serogroups presently known. On the basis of these findings and other morphological, biological, and serological properties of the organism, it is proposed that spiroplasma strains with these characteristics be classified as a new species, Spiroplasma mirum. Strain SMCA (ATCC 29335) is the type strain., language=, type=
