Abstract: | The serotype is most important for molecular epidemiological analysis of Listeria monocytogenes (L.m.) contaminating marketed meats. An improvement on the traditional method was thus attempted in the present study because of the requirement of swift and definite serotyping. In the determination of O-antigen, definite judgement was allowed by an immediate cooling at 80 degrees C after autoclaving the bacteria. In the determination of H-antigen, use of a culture plate without Craigie's tube yielded the active bacteria only by single culture. The stable and clear agglutination in many samples was also obtained with a microplate using less antiserum. The availability was confirmed with 123 strains and the serovar 1/2b was dominant in the Japanese strains. |
