[Studies on the serogroup of Yersinia enterocolitica. II. Selection and establishment on serogroup reference strains of Yersinia enterocolitica].
Since 1980, we have collected 1120 strains of Yersinia enterocolitica, from the different parts of China. These strains have been obtained from various sources in man, animals and natural environment accompanied by their clinical or ecological information of Yersinia enterocolitica. The results of our tests have shown that the 747 strains have exhibited the clinical morphological and biochemical characteristics of Yersinia enterocolitica. Through comparing under the same conditions, out of the 747 strains 335 have been selected out with better antigenicity and have been produced antisera from their representative strains. This set of antisera is very satisfactory for its potency and specificity. This set of antisera is ready to supply and have good efficacy and application facilitated for control strains on identifying strains and their epidemiologic observation.
