[A comparison of the results obtained in IgM serology and anti-Coxsackie A9 (strain 47) neutralization in cases of epidemic neuropathy and their contacts].

A number of 213 monosera from patients presenting with epidemic neuropathy and their contacts was studied by indirect immunofluorescence and neutralization tests with the aim of demonstrating the presence of serum IgM and neutralizing antibodies against the strain 47/93 IPK identified as a Coxsackie A9 virus. The mean age of the patients ranged from 20 to 59 years and positivity to both techniques was not found to be predominant for one or another sex. No significant difference was observed with respect to results obtained between patients and contacts with the techniques used for the study.
