本项调查于1986年7～10月在武汉进行。所分离的类志贺邻单胞菌(Ps)与气单胞菌(A spp)的生物学特征及DNAG+C Mol％(分别为53.0～53.6与59.2～59.8)与文献相符。同参考株DNA杂交率达89.8～98.4％。腹泻患者与健康者的Ps分离率(8.9％与2.4％)与志贺氏菌属相似(9.4％与2.4％)。两组Ps菌株的生化特性一致。两组的A spp分离率高于沙门氏菌属(4.9％与2.0％对2.0％与1.5％),以温和气单胞菌(A Sobria)为主,有的菌株具有肠致病性指征(赖氨酸和溶血试验阳性)。作者认为Ps与Aspp在腹泻病中的相对重要性与健康携带者的流行病学意义均应予注意。
The survey was conducted in Wuhan from July to October 1986. The biological characteristics and DNAG + C Mol% (53.0 ~ 53.6 and 59.2 ~ 59.8, respectively) of the isolates of Ps and A spp were consistent with the literature. DNA hybridization rate with the reference strain of 89.8 ~ 98.4%. Ps isolates (8.9% vs. 2.4%) from diarrhea patients and healthy controls were similar to those from Shigella (9.4% vs. 2.4%). The biochemical characteristics of the two strains of Ps were the same. The A spp separation rate was higher in both groups than in Salmonella (4.9% vs 2.0% vs. 2.0% vs. 1.5%), with A sobria predominating, and some isolates exhibiting intestinal pathogenicity Positive for lysine and hemolysis). The author believes that the relative importance of Ps and Aspp in diarrheal disease and the epidemiological significance of healthy carriers should be noted.
