19 Herpes virus type 2 (HSV2) is one of the most common sexually transmitted infections globally 20 with a very high prevalence in many countries. During HSV2 infection viral particles become 21 coated with complement proteins and antibodies, both existent in the genital fluids, which could 22 influence the activation of the immune responses. In genital mucosa, the primary target cells for 23 H...
Antisera prepared in rabbits against either whole encapsulated cells of Cryptococcus neoformans or purified cryptococcal polysaccharide were opsonic for the encapsulated yeast. The opsonic activity was removed by absorption with whole cryptococci and was inhibited by free polysaccharide. As little as 0.13 microgram of cryptococcal polysaccharide produced a 50% inhibition of opsonization. Variou...
Influenza A viruses cause annual epidemics and occasionally pandemics. Antibodies directed to the conserved viral nucleoprotein (NP) may play a role in immunity against various influenza A virus subtypes. Here, we assessed the immunological significance of a human monoclonal antibody directed to NP in vitro. This antibody bound to virus-infected cells but did not display virus-neutralizing acti...
Passively transferred immune serum provided significantly greater protection to BALB/c mice against attenuated Brucella abortus 19 than against virulent strain 2308, whether serum donors had been infected with strain 19 or 2308. In contrast, immune T cells conferred better protection upon recipients challenged with the homologous strain of B. abortus. It is hypothesized that strain 2308, but no...
