Abstract

Strains of phytopathogenic soft rot Erwinia spp. were examined for haemagglutinin (HA) production. Mannose-sensitive HA was found only in five of 15 strains of E. carotovora subsp. carotovora. Mannose-resistant HA (MRHA) was found in 12 of 15 strains of E.c. carotovora, ten of 13 strains of E.c. subsp. atroseptica and the single strain of E.c. subsp. betavasculorum, as well as all seven strains of E. chrysanthemi. MRHA, detectable only in a microtitre tray HA assay was of either broad- or narrow-spectrum activity when examined against blood of seven different animal species and could be inhibited by the beta-galactoside asialofetuin. Fimbriae of ca 10 nm diameter were found on MRHA(+) bacteria E.c. carotovora and E.c. atroseptica.

摘要

对植物致病软腐欧文氏菌属的菌株进行了血凝素（HA）产生情况的检测。仅在15株胡萝卜软腐欧文氏菌胡萝卜软腐亚种中的5株中发现了甘露糖敏感型HA。在15株胡萝卜软腐欧文氏菌胡萝卜软腐亚种中的12株、13株胡萝卜软腐欧文氏菌黑胫亚种中的10株、胡萝卜软腐欧文氏菌甜菜维管束亚种的单一菌株以及所有7株菊欧文氏菌中发现了甘露糖抗性HA（MRHA）。仅在微量滴定板HA试验中可检测到的MRHA，在针对7种不同动物物种的血液进行检测时，具有广谱或窄谱活性，并且可被β-半乳糖苷去唾液酸胎球蛋白抑制。在MRHA（+）的胡萝卜软腐欧文氏菌和黑胫亚种细菌上发现了直径约10nm的菌毛。
