中和试验检测到三种血清型猫合胞病毒（FSV）：低流行型906和高流行型702和951，它们之间存在微小的单向抗原差异。在某些情况下，自然感染猫的血清抗体中和951，但不中和702或906，这表明951可以被认为是主要的不同血清型。采用中和法、琼脂凝胶免疫扩散法和荧光抗体法检测了1977-1981年5年间猫中FSV抗体的流行率。在5年期间，951血清型抗体的流行率增加，在此期间，FSV抗体流行率的总体增加似乎与951血清型的传播有关。
Three serotypes of feline syncytial virus (FSV) were detected by neutralization tests: 906, a serotype of low prevalence and 702 and 951 which were serotypes of higher prevalence, between which a minor 1-way antigenic difference was detected. Serum antibody in naturally-infected cats in some cases neutralized 951, but not 702 or 906 which suggested that 951 could be considered as a major distinct serotype. An increase in prevalene of antibody to FSV in cats over a 5 yr period from 1977-1981 was detected by neutralization, agar gel immunodiffusion and fluorescent antibody techniques. Over the 5 yr period the prevalence of antibody to the 951 serotype increased and the overall increase in prevalence of antibody to FSV during this period appeared to relate to dissemination of the 951 serotype.
