Description of Campylobacter gastrosuis sp. nov.
| Genus name | Campylobacter |
| Species name | Campylobacter gastrosuis |
| Specific epithet | gastrosuis |
| Species status | sp. nov. |
| Species etymology | (gas.tro.su’is., Gr. n. gaster gastros, stomach; L. n. sus suis, a pig; L. gen. n. gastrosuis, from a pig’s stomach) |
| Description of the new taxon and diagnostic traits | The cell is Gram-negative, motile, and spiral-shaped after 48 h of growth on Karmali or Columbia agar with 5% defibrinated sheep blood in a microaerophilic atmosphere at 37 °C. The colonies are wet, flat, grey, circular, and smooth but may vary in size and morphology after a long incubation. No hemolysis on blood agar was observed. Cells are negative activities for catalase, oxidase, and urease, and could not produce H2S. No hydrolysis of hippurate. Nitrate can be reduced and indoxyl acetate can be hydrolyzed. The isolate was resistant to different types of antibiotics, namely erythro-mycin, azithromycin, nalidixic acid, tetracycline, telithromycin, and clindamycin, and carries multiple resistance relative genes and has an MDRGI. |
