Experimental infection of neonatal pigs with Campylobacter sputorum subspecies mucosalis with special reference to the oral cavity

After oral exposure Campylobacter sputorum subsp. mucosalis became established in the mouth of piglets for up to eight weeks. C. sputorum subsp. mucosalis was not isolated from the same pigs each week, although some pigs were positive for a number of consecutive weeks. Spread also took place from orally dosed piglets to an undosed litter mate maintained with them. Other catalase negative, serologically distinct Campylobacters were also demonstrated in the oral cavity.
