Possible routes include either oral-oral or fecal-oral, iatrogenic spread inadvertent use unsterile pH probes endoscopes, vectorial flies. Evidence to support each route transmission provided, there no predominant route. The only significant reservoir appears be humans themselves. organism has been found some domestic cats nonhuman primates, opportunities for human interaction latter are rare, making from this source an unlikely possibility. propensity become a coccoid form. This may represent persistent form which can exist environment, it yet shown that revert replicative
