cross reactivity for IGM response between coxsackieb viruses and hepatitis A virus

A solid phase enzyme imunoassay [Elisa] was used to study the pattern of cross reactivities between immunoglobulin M [IgM] specific for coxsackie B viruses [CBV] serotypes in 26 sample of human sera. It was found that 42% of the samples were showing a cross reactivities with different CBV serotypes. Interstingly 55% of those cross reacting sera were showing cross reactivities. Thus, a cross reactivities among the CBV serotypes may be an indication for other cross reactivities within the Enteroviruses family
