作者观察了饮食中长期中度缺乏蛋白质对已经BCG免疫的近交系2和近交系13豚鼠防御结核杆菌毒力株H37Rv肺部攻击的作用。实验动物为150～250g的无病原体的雄性和雌性近交系2和近交系13豚鼠,随机接受实验性饮食,接受或不接受免疫接种处理。实验期间每周记录体重。实验性饮食分为低蛋白饮食(含10%卵白蛋白)、足量蛋白饮食(含30%卵白蛋白)和普通豚鼠饮食。给各饮食组中的一半豚鼠在开始采用实验饮食前3周皮下接种约含10~6活BCG菌的 The authors looked at the effects of dietary medium to long-term deficient proteins on lung challenge in BCG-immunized inbred line 2 and inbred line 13 guinea pig Mycobacterium tuberculosis virulent strain H37Rv. The test animals were 150-250 g pathogen-free male and female inbred lines 2 and 13 inbred guinea pigs, who were randomized to receive an experimental diet with or without immunization. Body weight was recorded weekly during the experiment. Experimental diet is divided into low protein diet (including 10% ovalbumin), adequate protein diet (containing 30% ovalbumin) and the general guinea pig diet. Half of each guinea pig in each diet group was subcutaneously inoculated with about 10 to 6 viable BCG bacteria three weeks prior to the start of the experimental diet
