We studied the thermo-resistance of E. rhusiopathiae serovar 2 (strain A), E. tonsillarum serovar 7 (strain B), Erysipelothrix spp. serovar 13 (strain C), and serovar 18 (strain D), E. rhusiopathiae serovar N (strain E), and strains which the serovars could not be determined by the usual method but could be determined as E. rhusiopathiae (strains F and G), and determined as Erysipelothrix spp. serovar 13 (strains H and I) by PCR, and, determined the D-values according the grown temperature. Strains D, and F to I, which lack the heat stable antigen or which the serovar could not be determined, showed higher D-values when grown at 37℃ than when the same strains grown at 25℃, while the strains having the heat stable antigen (A to D) did not show any significant differences. Strains of Erysipelothrix spp serovar 13 (C, H and I) showed D-values from 2.3 to 9.6 min, which was higher than those of strains A, B, D, E, F, and G which showed D-values from 0.6 to 1.7 min. Thus, the thermo-resistance of Erysipelothrix spp. might depend on the serovar, and also, it might be considered that heat stable antigens might be involved in the heat resistance of strains of this genus., P(論文), 特集, application/pdf, FEATURE ARTICLES}, pages = {148--150}, title = {Erysipelothrix属菌のD値に関する研究}, volume = {13/14}, year = {2007}, yomi = {モリタ, ヒデトシ and カトウ, ユキオ and ハヤシダニ, ヒデキ} }
