Human Immunoglobulin Specificity After Group B Arbovirus Infections

Group B arbovirus structural and nonstructural antigens. 3. Serological specificity of solubilized intracellular viral proteins.

Solubilized nonstructural antigen III from Saint Louis encephalitis (SLE)-Japanese B encephalitis (JBE)-West Nile (WN) and dengue-2 arbovirus-infected pig kidney cells was purified by employing Brij-58 solubilization, organic solvent extraction, and column chromatography. Diethylaminoethyl-cellulose column peak C eluate contained only intracellular viral envelope protein designated antigen I. A...

Myocarditis and cardiomyopathy after arbovirus infections (dengue and chikungunya fever).

The varying clinicalfeatures and sequelae in Io patients sufferingfrom myocarditis after dengue and chikungunya fever caused by arboviruses are described. These patients had significantly raised antibody levels in the serum and gave a recent history of 'dengue-like' fever. Afew patients had afavourable outcome with disappearance of symptoms, improvement in the electrocardiogram, and no residual...

Group B streptococcal infections.
