Twenty-nine lots of Bacti-Lab streptococci culture plates containing nalidixic acid, neomycin, and amphotericin B were inoculated with 25 strains of group A, B, C, F, and G strepotocci, 13 strains of nonstrepotcoccal organisms representative of the throat flora, and 198 fresh clinical thorat specimens to determine the accuracy of the plates in identifying group A streptococci. With the Bacti-Lab test plates 98.87% of the beta-hemolytic streptococcal strains tested produced growth 95.51% yielding more than 50 colonies. Of the nonstreptococcal beta-hemolytic and non-beta-hemolytic organism tested, 79.54% were inhibited by the selective media. When bacitracin disks were used for presumptive identification group A streptococci from clinical thorat specimens, 12.00% false positive and 0.00% false negative results were obtained as measured by the direct flourescent-antibody and Lancefield grouping methods.
用25株A、B、C、F和G组链球菌、13株代表咽喉菌群的非链球菌微生物以及198份新鲜临床咽喉标本接种29批含有萘啶酸、新霉素和两性霉素B的Bacti-Lab链球菌培养平板，以确定这些平板在鉴定A组链球菌方面的准确性。使用Bacti-Lab测试平板时，98.87%的受试β溶血性链球菌菌株生长，95.51%产生超过50个菌落。在受试的非链球菌β溶血性和非β溶血性微生物中，79.54%被选择性培养基抑制。当使用杆菌肽纸片从临床咽喉标本中初步鉴定A组链球菌时，通过直接荧光抗体法和兰斯菲尔德分组法测定，假阳性结果为12.00%，假阴性结果为0.00%。
