对 ４ 种质控考核菌株进行了细菌学鉴定，根据生物学培养，生化试验，血清学试验，噬菌体裂解试验确定：（１）９４０１：肠杆菌科，志贺氏菌属， Ｄ群宋内氏志贺氏菌；噬菌体裂解模式为 Ｓｈ， Ｅ。（２）９７００３ Ｈ２ Ｓ 阳性：肠杆菌科，沙门氏菌属，乙型副伤寒沙门氏菌；抗原结构式 Ｏ１，４，５，１２ ∶ Ｈｂ：１，２ ；噬菌体裂式为 Ｏ— Ｉ裂解。（３）９７００３ Ｈ２ Ｓ阴性：肠杆菌科，埃希氏菌属，肠道出血性大肠埃希氏菌（ Ｅ Ｈ Ｅ Ｃ）；抗原结构式 Ｏ１５７∶ Ｈ７；噬菌体裂解模式为 Ｓｈ， Ｅ， Ｅ４。（４）９７００４：弧菌科，弧菌属，拟态弧菌。有无丰富的专业知识，在质控考核中的顺利程度会有明显的差别；要依照国标食品卫生检验方法中微生物学部分和何晓青主编《卫生防疫细菌检验》制定检验程序和实验方法；虚心向有经验的同志求教；大胆尝试先进的细菌学鉴定技术；在实验中一定要认真，耐心。
Bacteriological identification of four quality control test strains was carried out. According to the biological culture, biochemical test, serological test and phage lysis test, (1) 9401: Enterobacteriaceae, Shigella, D Shigella; phage lysis mode Sh, E. (2) 97003 H2S positive: Enterobacteriaceae, Salmonella, Salmonella paratyphi B; antigenic structure O1,4,5,12: Hb: 1,2; phage split for the O-I cleavage. (3) 97003 H2S Negative: Enterobacteriaceae, Escherichia, Enterohemorrhagic Escherichia coli (EHEC); Antigen O157: H7; Phage lysis mode is Sh, E, E4. (4) 97004: Vibrio, Vibrio, mimicry Vibrio. Whether rich professional knowledge in the quality control assessment of the smooth degree there will be significant differences; in accordance with the national standard of food hygiene testing methods in the microbiology and He Xiaoqing editor of “health and epidemic prevention bacteria test” to develop test procedures and experimental methods; open-minded Experienced comrades seeking advice; bold attempt to identify advanced bacteriology identification technology; in the experiment must be serious and patient.
