Abstract: The efficiencies of Rappaport medium, strontium chloride, strontium selenite and selenite F broths for enrichment in the isolation of salmonellas from human stools were compared. The study showed that Rappaport medium when used in conjunction with strontium selenite broth gave the most satisfactory result, because they covered the isolation of a wider range of salmonellas. With these media, the carriage rate of Salmonella serotypes of 3,325 hospital patients who were admitted without complaints of diarrhoea or gastroenteritis or enteric fever, were tested. The result revealed that 5.6% of them carried Salmonella serotypes ranging from those that may produce food-poisoning to those which are causal agents of enteric fever. Moreover, patients who were infected with the liver-fluke, Clonorchis sinensis, had a higher carriage rate than those who were infected with other intestinal parasites or non-infected. / サルモネラ分離に際してRappaport培地,strontium chlorideブイヨン,strontium seleniteブイヨンおよびselenite Fブイヨンの4種の増菌培地を用い,その成績を比較した.その結果,Rappaport培地にstrontium seleniteブイヨンを併用すると,サルモネラの各種類の分離に最も満足すべき成績がえられた.これらの培地を用いて,下痢を全く伴わない患者,胃腸炎あるいはチフス性疾患の患者3,325名についてサルモネラ保菌率を検査した.その結果,22の血清型に属する189株のサルモネラを分離した.検出率は5.6%である.その血清型は,食中毒の原因と推定されたものから,チフス性疾患の原因菌に至るさまぎまの型が含まれていたが,最も多く分離されたのはS. derbyとS. anatumであった.また,Clonorchis sinensisに感染していた患者は,他の腸寄生虫感染者あるいは非感染者より高率にサルモネラを保有していた.
