不同来源(如外环境、食物和人群)的结肠炎耶尔森氏菌(Yersinia Enterocolitiac,Y.E.)目前已成为引起食物性胃肠炎暴发流行的重要病原菌之一。从牛乳和乳制品中检出Y.E.已有不少报告,并发现虽经巴氏消毒的液体乳制品亦呈阳性。Hughes报告,从巴氏消毒的牛乳和奶油中分离出5 a血清型的Y.E.,当把该血清型菌株以10~8/ml菌细胞加入牛乳中,能在 4℃中生长繁殖,虽经巴氏消毒仍有存活。本文作者对36株从生牛乳中分离的Y.E菌株,在含有0.6%酵母浸汁的胰酶大豆肉汤
Yersinia Enterocolitiac (Y.E.) from different sources (such as external environment, food and people) has now become one of the important pathogens causing the outbreak of food-borne gastroenteritis. There have been a number of reports of Y.E. from milk and dairy products and it has also been found that liquid dairy products that are pasteurized are also positive. Hughes reported 5-serotype YE isolated from pasteurized milk and cream. When the serotype was added to milk at 10 to 8 cells per ml, it grew and grew at 4 ° C, Sterilization is still alive. The author of the 36 strains isolated from raw milk Y. E strains, containing 0.6% yeast extract juice tryptic soy broth
