Serologic responses to proteins of rotavirus serotypes G1, P1A[8]; G2, P1B [4]; G3, P1A[8]; and G4, P2A[6] were evaluated by immunoblotting paired sera from 17 children with primary rotavirus infection. Ten children were infected with G1, P1A[8]; five with G4, P1A[8]; and two with G4, P2A[6] viruses

Abstract
Some aspects of rotavirus humoral immunity were assessed on the basis of distinguishing se‐rotype‐specific specificities (VP4/VP7) by using rotavirus reassortants, human and animal strains in neutralization assays in serum samples obtained during the acute phase, and 1, 6 and 12 months after primary natural infection. In this study, all the infecting virus strains were characterized as G type and some also as P type. Primary natural infection induces a significantly greater homotypic neutralization response than heterotypic response. In addition, there was no significant difference in the number of homotypic or heterotypic responses following reinfection. Transplacentally acquired homotypic antibodies were associated with protection against dehydration during rotavirus gastroenteritis. © Wiley‐Liss, Inc.

Worldwide trials of rotavirus vaccines are currently in progress, but the basis of cross-reactive immunity between rotavirus serotypes is yet to be elucidated. The involvement of the outer capsid proteins, VP7 and VP4, in the production of cross-reactive neutralizing antibody (N-Ab) is unclear, and
## Abstract The early activation of T‐ and B‐cell responses to cytomegalovirus was studied in immunosuppressed patients. Primary lymphocyte stimulation to cytomegalovirus (CMV) antigen, a measure of T‐helper activity, and anti‐CMV IgG subclass responses were analyzed. Ten patients suffering from pr
The serum antibody responses of babies to the variable carboxy-terminal region of the attachment ( G ) protein of respiratory syncytial virus (RSV) have been analysed using paired acute and convalescent sera from infants experiencing their first RSV infection with viruses of known genotype.

The humoral immune response to HSV-1 and HSV-2 proteins was examined in patients with primary first-episode genital herpes. Ten patients had culture-proven HSV-1 infections, 37 had HSV-2 infections, and all were seronegative to HSV proteins before developing their infections. Development of serum an
A prediction of the theory of immunologic surveillance is that tumour antigens can be recognised by cell-mediated immunity during early development of the primary tumour by formation of tumour antigen-specific cytotoxic lymphocytes (CTLs) and that such recognition leads to destruction of those tumou
