摘　　要：本文对山东省9市（地）临床和外环境等6种标本中检出的260株气单胞菌进行了表型特性研究。结果表明：山东省以温和气单胞菌为主（52.69％），嗜水气单胞菌（23．4％）、豚鼠气单胞菌（23.08％）次之。自淡水鱼中检出维隆气单胞菌和易损气单胞菌各1株。随机抽取163株应用溶血试验、CHO细胞测毒素试验、兔肠结扎及CT基因探针杂交试验进行毒素原性研究，温和、嗜水及豚鼠气单胞菌均可产生溶血素、肠毒素，某些菌株的肠毒素具有与严乱肠毒素呈交叉反应因子（CTCE）。The phenotypic charaters and the pathogenic facrors of 260 aeromonas isolatod from 6 different Kinds of specimens such as clinic and enviromental materials were stulied. The result showed that A. sobria was most common. accounts for 52.6%, folowed by A.aydropohila and A. caviaae which account for 23.46% and 23.08% respechvely. A sthen of A.veronii and a. sttain of A. trota were isolated from freshwater fish. 163 sthans were randotnly sampled and then their pathogenic factors were studied with hemolysin test CHO cell virulence-detecting test, rabbit enteroligation as well as CT gene probe hybridization. The study result suggested that A sobria, A. aydrophila and A. caviae could produce hemolysin and enterotoxin. The enterotoxin from some strains contains certain factors (CTCE) which coud cross-react with cholera enterotoxin.
