Family Infections by Reo-Like Virus: Comparison of Antibody Titres by Complement Fixation and Immunoelectroosmophoresis

Abstract
The families of 31 index cases infected by reo-like virus were examined for gastroenteritis symptoms, virus excretion and serological evidence of infection. Excretion of virus was seen only among the children in the families and it occurred with gastroenteritis symptoms in 97.2% of all cases. Virtually all infected children had a significant rise in titer in paired sera. Among the parents, 25.0% had a significant rise in titer associated with infections with gastroenteritis symptoms and 28.6% with symptomfree infections. A comparison between complement fixation and immunoelectroosmophoresis for detection of antibody showed that the tests gave similar results.
