Phylum Proteobacteria, Class Epsilonproteobacteria, Order Campylobacterales, Family Helicobacteraceae, Genus Helicobacter,
Helicobacter salomonis Jalava et al. 1997.
Cells are loosely helical or curved rods 0.8-1.2 x 5-7 μm. Coccoid forms appear in old
cultures. Cells exhibit a more pronounced corkscrew-like appearance when studied
in situ in mucosal tissue samples. Cells exhibit a relatively slow, wave-like motility
that is attained by means of multiple sheathed flagella arranged at one or both ends
of the cell body.
Individual colonies are not formed, but cultures grow as spreading films on fresh
moist agar media. Grow at 37 ºC,but not at 25 or 42 ºC. Do not grow in the presence
of cefoperazone (60 mg/l). Some strains (17%) tolerate 5-fluorouracil (100 U/l). Can
grow on blood-supplemented BHI, brucella, nutrient, and Mueller-Hinton agar media.
Do not grow on media containing 1% ox bile, 1% glycine, or 1.5% NaCl.
Isolated from a gastric biopsy of a healthy dog. Resistant to nalidixic acid and susceptible to cephalothin and cefoperazone.

Helicobacter sp. Related to Helicobacter felis and Helicobacter bizzozeronii. Int J Syst Bacteriol October 1997 47:975-982.
H. felis, H. bizzozeronii, and H. salomonis are biochemically and 16S rRNA gene sequence very similar.
Positive results for catalase, oxidase, urease, nitrate reduction, gamma-glutamyl transpeptidase, TTC reduction, indoxyl acetate &
Negative results for hippurate hydrolysis, pyrrolidonyl arylamidase, L-arginine arylamidase, L-aspartate arylamidase tests & tolerance
to 1% glycine.
