Sneath and Stevens 1990.
Synonyms: group “Ross” (Kilian and Frederiksen, 1981), Phenon 17 (Sneath and Stevens, 1985).
Gram-negative small bacilli or coccobacilli , nonmotile.
Colonies are semitransparent, grayish on Sheep blood agar, and about 2 mm in
diameter after 48 hours at 37 ºC, occasionally producing weak hemolysis.
Growth is aerobic and facultatively anaerobic. Growth on MacConkey agar is variable.
V-factor independent growth. Mesophilic.
Isolated from vaginal exudate, aborted piglets, tonsils, lungs, liver, intestines, bone and brain of pigs.
Unknown.
