In 1998 South Africa experienced a major influenza epidemic that was characterized by extensive illness and an unusually early season. The impact of the epidemic was charted by measuring proxy indexes of influenza activity such as school absenteeism

The genetic stability of the three Sabin oral poliovaccine (OPV) strains produced on either primary monkey kidney (VK) or Vero cell substrates was compared in vivo and in vitro by measuring the rate at which the bases most strongly associated with at

False negativity in a commercial anti-HIV kit (IMx HIV-1/HIV-2 3rd Generation Plus (code 8B32) was investigated, and the kit that superseded it (IMx HIV-1/HIV-2 III Plus, code 8C98) was evaluated. In a comparison on 574 freshly collected anti-HIV-1-p

The molecular epidemiology of wild-type 1 polioviruses isolated in South Africa during 2 major poliomyelitis epidemics in the 1980s and during the pre- and inter-epidemic periods was investigated by partial sequence analysis across the VP1/2A junctio

The genetic relationships between type 1 polioviruses circulating in sub-Saharan Africa during the past decade have been investigated by partial genomic sequencing across the VP1/2A region of the polioviral genome. Sequencing templates were generated

Chikungunya (CHIK) strains from Africa and Asia were shown to be antigenically closely related using a panel of monoclonal antibodies (mAb) prepared against strains H817 from Africa and PhH15483 from Asia. The one-way antigenic relationship between C

The last confirmed case of poliomyelitis in Namibia had been reported in 1988. However, between Nov 8, 1993, and Jan 7, 1994, 27 cases of paralytic poliomyelitis were confirmed in the country. The outbreak was limited to the south health region; at l

Summary Monoclonal antibodies (mAb) were used to examine possible stages at which antibody-mediated neutralization of Rift Valley fever virus occurs, and to assess whether binding of antibody is dependent on viral protein structure in order that anti

A panel of monoclonal antibodies (MAbs) mapping to different antigenic sites on the RVFV G 1 and G 2 proteins were used to examine the mechanisms involved in neutralization of the virus. Three types of synergistic neutralization of RVFV were observed
