一般描述

胰蛋白胨大豆琼脂(TSA)是一种用于分离和培养苛养和非苛养微生物或维持储备培养物的通用培养基。它是一种用于各种细菌、酵母菌和霉菌培养和分离的复合培养基。TSA培养基混合酪蛋白胨和大豆胨两种蛋白胨，提供氨基酸和长链肽等有机氮营养。氯化钠维持渗透压平衡，大豆蛋白胨中的天然糖类提供能源。

应用

胰蛋白胨大豆琼脂可用于薄膜过滤法的预培养和计数步骤（大肠杆菌）。适用于需氧和厌氧细菌的培养。培养基不含X因子（血红素）和V因子（辅酶Ⅰ），加入X因子和V因子纸片后，可用于鉴定嗜血杆菌(Haemophilus sp.)。

Chronobacter spp. Classic and Detection Methods

Cronobacter spp. are frequently found on vegetables, meat, fermented bread, dairy and in baby food. Consumption of contaminated powdered infant formula milk can result in sepsis, infant meningitis and necrotizing enterocolitis.

Vibrio Detection

Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.

弧菌检测

大多数弧菌采用葡萄糖等简单的 C 源作为能源，需要2-4％的NaCl或其他盐以及海水中存在的微量元素，即可实现最佳生长。有些物种可以使用多种能源。

Detection and Identification of Campylobacter

Campylobacter grows only on complex media that have been amended with diverse essential amino acids and supplements. We offer a broad range of specific agars and broths for the detection, identification, and cultivation of Campylobacter.
