从全国23个省、市、自治区的46份马铃薯块标本中分离到25株菊欧氏杆菌(Erwinia carysanthe-mi).经58项细菌学性状的研究,发现它们在酒石酸钠,乳酸钠,丙酸钠,菊糖,蜜二糖,D—山梨醇等项反应中有差别.据此将这25个菌株分为3个生物型,其中生物型Ⅰ是来自江苏的10个菌株;生物型Ⅱ是来自四川仁寿县和彭县的,也是10个菌株;生物型Ⅲ共4个菌株来自河北和内蒙。生物型Ⅰ和Ⅱ与Dickey系统中的生物型Ⅱ相似,而生物型Ⅲ则与任何已划分的生物型都有一定差异. 经微量凝集反应和琼脂双扩散血清学试验,25菌株至少有3个不同的血清型。本研究中的生物型,血清型及其地理来源之间存在着明显的对应关系。
Twenty-five strains of Erwinia carysanthe-mi were isolated from 46 potato samples collected from 23 provinces, municipalities and autonomous regions in China. The 58 bacteriological traits were studied and found to be effective against sodium tartrate, sodium lactate, propionic acid Sodium, inulin, melibiose, D-sorbitol, etc. The 25 strains were divided into three biotypes, of which biotype I was from 10 strains of Jiangsu; Biotype II was Ten strains were also from Renshou County and Pengxian County in Sichuan Province. A total of 4 biotype III strains were from Hebei and Inner Mongolia. Biotypes I and II are similar to Biotype II in Dickey system, while Biotype III is different from any of the divided biotypes.After microcoagulation and agar double diffusion serological tests, there are at least three Different serotypes. There is a clear correspondence between the biotypes, serotypes and their geographical origin in this study.
