Biologically functional clade C envelope (Env) glycoproteins from the chronically (donor) and newly (recipient) infected partners of four heterosexual transmission pairs in Zambia were cloned and characterized previously. In each case, the donor viral quasispecies contained Envs that were resistant to autologous neutralization by contemporaneous plasma, while the recipient Envs were sensitive t...
Neutralization of human papillomavirus type 11 (HPV-11) has been demonstrated using serum and cervical secretions from primates vaccinated with virus-like particles (VLPs). Theoretically, neutralizing antibodies could protect women from HPV infection. The immunogenicity of a yeast-derived HPV-11 L1 VLP vaccine was tested in women. Serum specimens were evaluated for HPV-11 titer by competitive r...
The aim of this study was to develop a highly sensitive human papillomavirus type 31 (HPV31) neutralization assay based on the production of pseudovirions carrying luciferase. Neutralizing antibodies against HPV31 were investigated in a set of HPV31 monoclonal antibodies and in women with evidence of HPV31 infection. Neutralizing antibodies were detected in 78% of subjects with a positive enzym...
We evaluated toxigenic Clostridium difficile detection by a lateral flow assay for antigen and toxin, an enzyme immunoassay, and two commercial PCR methods. Compared to the cell cytotoxicity neutralization assay and toxigenic culture, both toxin detection methods lacked sensitivity. PCR following combined antigen and toxin detection provided the most useful diagnostic information.

Passive antibody prophylaxis against human immunodeficiency virus type 1 (HIV-1) has been accomplished in primates, suggesting that this strategy may prove useful in humans. While antibody specificity is crucial for neutralization, other antibody characteristics, such as subclass, have not been explored. Our objective was to compare the efficiencies of immunoglobulin G (IgG) subclasses from pol...
