In order to establish a national reference system for Campylobacter serotyping in Japan, 7 local institutes of public health collaborated to prepare 30 serogrouping antisera including 26 antisera of Lior's serogrouping system and 4 antisera of TCK serogrouping system which was developed by the Tokyo Metropolitan Research Laboratory of Public Health. A total of 603 strains (92.2%) out of 654 isolates from 23 outbreaks of C. jejuni throughout Japan were serogrouped by the 30 antisera. Out of 1,198 strain isolated from sporadic cases of Camplyobacter gastroenteritis, 883 (73.7%) were typed and 298 strains (24.9%) were untypable. The remaining 17 strains belong to rough form were not used for serogrouping. A hundred thirteen out of 883 strains have reacted with more than one typing serum. Among C. jejuni isolated from 7 prefecture, Lior's serogroup 4 was most common followed by Lior's serogroup 4, 2, 11, 1 and TCK serogroup 1 and 12. We conclude from the experiment described above that this Lior's serogrouping system by combining with TCK serogroup for Campylobacter jejuni/coli is useful in epidemiological investigations in Japan.
