• Three kinds of mutans streptococci ; Streptococcus ferus and two Streptococcus orisuis serovar strains, in the pig oral cavity were identified previously. The ability to form plaque and synthesise insoluble glucan from sucrose was relatively limited in S. ferus and S. orisuis compared with Streptococcus mutans. PCR analysis showed that the two S. orisuis serovar strains possessed a glucosyltransferase (GTase) I gene. S. ferus could not be amplified with GTase B and GTase I primers. Acid production of all test strains was similar and depended on the cell number. In rat caries experiments, S. ferus and the two S. orisuis serovar strains achieved a lower caries score than S. mutans. The total number of bacteria in the rat oral cavity was also lower for these strains than for S. mutans. The S. ferus and two S. orisuis serovar strains from pigs had relatively weak cariogenic potential compared to S. mutans.
