    In the winter of 2014/15 a novel GII.P17-GII.17 norovirus strain (GII.17 Kawasaki 2014) emerged, as a major cause of gastroenteritis outbreaks in China and Japan. Since their emergence these novel GII.P17-GII.17 viruses ...
  • Mans, Janet; De Villiers, J.C. (Johanna Corrie); Du Plessis, Nicolette M.; Avenant, T.J. (Theunis Johannes); Taylor, Maureen B. (Elsevier, 2010-08)
    BACKGROUND: Noroviruses (NoVs)are important enteric pathogens that cause gastroenteritis worldwide. The first documented NoV outbreaks in South Africa(SA)were described in 1993. The current NoV prevalence and circulating ...
  • Murray, Tanya Y.; Mans, Janet; Taylor, Maureen B. (IWA Publishing, 2013)
    Over a 2-year period, from January 2009 to December 2010, water samples were collected from three rivers (Klip, Rietspruit and Suikerbosrand) in the Vaal River System, South Africa. Enteric viruses were recovered by a ...
