A total of 600 samples of nose swabs collected from Hebei Province, China, were examined by polymerase chain reaction (PCR) for the presence of Streptococcus suis in healthy swine and the serotype were identified. Results showed that 148 strains (24.67%) of 600 tested were positive with S. suis, including 27 strains (18.24%) were identified to be type 7, 24 strains (16.22%) were type 2 and 20 strains (13.51%) were type 9. Butserotypes of other 75 strains (50.68%) were undetermined. To our knowledge, this is the first epidemiological investigation of S. suis in healthy swine from Hebei Province of China.   Key words:  Streptococcus suis, polymerase chain reaction (PCR), serotype, epidemiological.
