Indirect immunofluorescence and hemagglutination study of reactivity to human cytomegalovirus immediate early, early, and late antigens revealed that antibody responses to these antigens varies greatly and that hemagglutination is positive when sera contain only antibody to one or both early antigens.

Visna virus particles inhibit influenza virus hemagglutination in an assay for neuraminic acid-containing viruses. Pretreatment of visna virus with neuraminidase abolished hemagglutination inhibition activity but did not significantly affect attachment, infectivity, or virus-induced cell fusion in sheep choroid plexus cell monolayers.

Monoclonal antibodies were derived against the SA11 simian, NIC bovine, and Wa human rotavirus strains and characterized by enzyme-linked immunosorbent assay, plaque neutralization, and hemagglutination inhibition. Several strain SA11-specific antibodies were found to have neutralizing and hemagglutination-inhibiting capacity.

Porcine parvovirus (PPV) is a major cause of reproductive failure in swine and has caused substantial losses throughout the world. Viral protein 2 (VP2) PPV structural that can self-assemble into virus-like particles (VLP) with hemagglutination (HA) activity. In order to identify essential residues involved mechanism capsid assembly further understand function HA, we analyzed series deletion mu...

Members of the family Enterobacteriaceae are major cause nosocomial infections, including approximately 70% gastrointestinal 60% to urinary tract infections (UTIs), and septicemias. Since 1990, members have emerged as predominant pathogens causing UTIs. In this study, we performed phenotypic testing virulence factors in uropathogens. A total 118 uropathogens belonging were isolated from suspect...
