Abstract

Selenite F broth and a modified Muller-Kauffmann tetrathionate broth were investigated using sewage-polluted natural water as inocula. The modification of the tetrathionate medium was necessary as commercial alternatives would not allow multiplication of small numbers of salmonellas. The wide range of molar concentrations in different tetrathionate broths was emphasized. Selenite F broth was more efficient than Muller-Kauffmann tetrathionate broth, in our hands, with the material tested. Direct inoculation of the enrichment media was used. Each of the two media examined had a bias towards selection of certain serotypes. If possible, both enrichment broths should be used to obtain maximum information.

摘要

使用受污水污染的天然水作为接种物,对亚硒酸盐F肉汤和改良的穆勒-考夫曼四硫磺酸盐肉汤进行了研究。由于市售的替代培养基无法使少量沙门氏菌繁殖,因此有必要对四硫磺酸盐培养基进行改良。强调了不同四硫磺酸盐肉汤中摩尔浓度范围很广。在我们的实验中,对于所测试的材料,亚硒酸盐F肉汤比穆勒-考夫曼四硫磺酸盐肉汤更有效。采用了直接接种富集培养基的方法。所检测的两种培养基对某些血清型的选择都有偏向性。如果可能的话,应同时使用两种富集肉汤以获取最大信息量。
