A group C latex agglutination reagent, included as the negative control in the PathoDx Strep A latex agglutination test (Diagnostic Products Corp., Los Angeles, Calif), was compared with culture for rapid detection of group C streptococci (Streptococcus equi, S. equisimilis, S. zooepidemicus, and S. dysgalactiae) from swabs of veterinary specimens. The overall sensitivity of the latex test was 78%, and specificity was 97.6%. Only 25% of S. dysgalactiae isolates were detected, thereby accounting for the relatively low sensitivity. Ninety-three percent of the group C streptococci other than S. dysgalactiae were isolated from horses. When the latex test was evaluated for detection of group C streptococci other than S. dysgalactiae from horses, the sensitivity and specificity were 95.3 and 100%, respectively. We found the group C latex agglutination test to be a rapid and accurate method for the detection of the major pathogenic group C streptococci from swabs of equine specimens.
在PathoDx A群链球菌乳胶凝集试验（诊断产品公司，加利福尼亚州洛杉矶）中作为阴性对照的C群乳胶凝集试剂，与用于从兽医标本拭子中快速检测C群链球菌（马链球菌、类马链球菌、兽疫链球菌和停乳链球菌）的培养方法进行了比较。乳胶试验的总体敏感性为78%，特异性为97.6%。仅检测到25%的停乳链球菌分离株，因此敏感性相对较低。93%的非停乳链球菌C群链球菌分离自马。当评估乳胶试验用于检测马的非停乳链球菌C群链球菌时，敏感性和特异性分别为95.3%和100%。我们发现C群乳胶凝集试验是一种从马标本拭子中检测主要致病性C群链球菌的快速准确方法。
