【摘要】 目的了解哈夫尼亚菌的生物学特性。方法检测哈夫尼亚菌的一般特征、生化特性和血清学特性。结果本研究中的4株哈夫尼亚菌为革兰氏阴性小杆菌,氧化酶阴性,硝酸盐还原阳性,能够发酵葡萄糖产酸产气,不分解乳糖、蔗糖等,不产生H2S,各菌株能分别与沙门菌或志贺菌多价血清发生凝集反应,在生理盐水中不发生自凝。结论哈夫尼亚菌的生化特性复杂,主要特征稳定,但没有统一的系统反应模式;抗原结构也非常复杂,部分类似于沙门菌,部分类似于志贺菌,部分类似于大肠埃希菌等等。更多还原

【Abstract】 OBJECTIVE To investigate the biological characteristics of Hafnia. METHODS We observed the shape and stain of Hafnia and tested the biochemical and serological characteristics of the bacteria. RESULTS The 4 strains of Hafnia studied in the paper were small bacteria which were Gram negative. When their biochemical characteristics were tested,oxidase was negative,nitrate deoxidation was positive,they could ferment glucose into acid and gas,but could not ferment lactose and sucrose. On serology,some of the strains had the antigen of Salmonella,some had Shigella and some had Escherichia. CONCLUSION The biochemical characteristics of Hafnia was complicated,although the main biochemical characteristics was stable,the standard model of this characteristics could be found. On serology,the antigen of Hafnia was also complicated,it could be the antigen of Salmonella,Shigella or Escherichia,et al.更多还原
