【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:本次研究中分离出的细菌为革兰阴性小杆菌,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,与沙门菌多价血清以及O9,Hd,Vi因子血清发生凝集反应,在生理盐水中不发生自凝。结论:本次研究中分离出的细菌为血清学特征与伤寒沙门菌类似的哈夫尼亚菌。更多还原

【Abstract】 Objective:To investigate the biological characteristics of Hafnia.Methods:To observe the shape and strain of Hafnia and to test the biochemical and serological characteristics of the bacteria.Results:The bacteria studied in this paper was small bacteria which were Gram negative.When its biochemical characteristics were tested,oxidase was negative,nitrate deoxidation was positive,it could ferment glucose into acid and gas,but could not ferment lactose and sucrose.On serology,the strain of this bacteria had the antigen of Salmonella typhi.Conclusion:The bacteria studied in this paper was a strain of Hafnia which had the similar serological characteristics of Salmonella typhi.更多还原
