A total of 127 isolates were used to evaluate the Minitek Gram-Positive Set for identification of streptococci cultured from bovine mammary glands. The overall accuracy of the Minitek Gram-Positive Set was 34.6%. Of 12 Streptococcus agalactiae strains, 4 (33.3%) were correctly identified. Of 43 Streptococcus dysgalactiae strains, 32 (74.4%) were identified correctly. Of 44 Streptococcus uberis strains, 42 (95.5%) were identified as Enterococcus spp. Poor performance was attributed to the limited number of veterinary strains in the data base. Incorporation of large numbers of veterinary isolates into the data base is needed for further development of this system.
总共127株分离菌用于评估Minitek革兰氏阳性鉴定试剂盒对从牛乳腺中培养出的链球菌的鉴定能力。Minitek革兰氏阳性鉴定试剂盒的总体准确率为34.6%。在12株无乳链球菌菌株中,4株(33.3%)被正确鉴定。在43株停乳链球菌菌株中,32株(74.4%)被正确鉴定。在44株乳房链球菌菌株中,42株(95.5%)被鉴定为肠球菌属。性能不佳归因于数据库中兽医菌株数量有限。该系统的进一步开发需要将大量兽医分离菌纳入数据库。
