Abstract
Pups of both the California and Stellar sea lions have no intestinal enzymes for hydrolysis of sucrose, lactose, cellobiose, or trehalose. If these animals were given lactose or sucrose, they developed severe fermentative diarrhea and weight loss similar to the clinical syndrome encountered in infants with either hereditary or acquired intolerance to disaccharides. quired intolerance to disaccharides.
摘要
加利福尼亚海狮和北海狗的幼崽都没有用于水解蔗糖、乳糖、纤维二糖或海藻糖的肠道酶。如果给这些动物喂食乳糖或蔗糖，它们会出现严重的发酵性腹泻和体重减轻，这与遗传性或后天性双糖不耐受婴儿所出现的临床综合征相似。 后天性双糖不耐受。
