Immunol.1966 Feb 01; 96 AB - Hemagglutination-inhibiting (HI) antibody responses for coxsackievirus types B1, B3 and B5 were compared with neutralizing antibody responses with respect to sensitivity, specificity and diagnostic value in patients with and without coxsackievirus infections. Most sera possessed nonspecific inhibitors for hemagglutinins of these viral types, but treatment of sera with filtrates from a psychrophylic Pseudomonas sp. was found to be highly effective for removing such inhibitors; this treatment appeared to have little or no detrimental effect on specific antibody. HI tests on treated sera were comparable to neutralization tests in diagnostic value, with 46% of patients with isolations of coxsackievirus types B1, B3 and B5 showing significant rises in homotypic antibody titers by both tests. Heterotypic antibody rises seen in HI tests on treated sera corresponded with those observed in neutralization tests. HI antibody was rarely observed in treated sera in the absence of neutralizing antibody for the corresponding viral type.
