  • Antibody responses to Marburg virus in Egyptian rousette bats and their role in protection against infection 
    Storm, Nadia; Jansen van Vuren, Petrus; Markotter, Wanda; Paweska, Janusz Tadeusz (MDPI Publishing, 2018-02-10)
    Egyptian rousette bats (ERBs) are reservoir hosts for the Marburg virus (MARV). The immune dynamics and responses to MARV infection in ERBs are poorly understood, and limited information exists on the role of antibodies ...
  • Comparative evaluation of the diagnostic performance of the prototype Cepheid GeneXpert Ebola assay 
    Jansen van Vuren, Petrus; Grobbelaar, Antoinette A.; Storm, Nadia; Conteh, Ousman; Konneh, Kelfala; Kamara, Abdul; Sanne, Ian; Paweska, Janusz Tadeusz (American Society for Microbiology, 2016-02)
    The Ebola virus disease (EVD) outbreak in West Africa has highlighted an urgent need for point-of-care (POC) assays for the diagnosis of this devastating disease in resource-limited African countries. The diagnostic ...
  • Development and evaluation of a real-time reverse transcription-loop-mediated isothermal amplification assay for rapid detection of Rift Valley fever virus in clinical specimens 
    Le Roux, C.A. (Chantel Anne); Kubo, T.; Grobbelaar, Antoinette A.; Jansen van Vuren, Petrus; Weyer, Jacqueline; Nel, Louis Hendrik; Swanepoel, Robert; Morita, K.; Paweska, Janusz Tadeusz (American Society for Microbiology, 2009-03)
    This paper reports on the development and validation of a real-time reverse transcription-loop-mediated isothermal amplification assay (RT-LAMP) targeting the genomic large RNA segment of Rift Valley fever virus (RVFV). ...
  • Experimental inoculation of Egyptian fruit bats (Rousettus aegyptiacus) with Ebola virus 
    Paweska, Janusz Tadeusz; Storm, Nadia; Grobbelaar, Antoinette A.; Markotter, Wanda; Kemp, Alan; Jansen van Vuren, Petrus (MDPI Publishing, 2016-01-22)
    Colonized Egyptian fruit bats (Rousettus aegyptiacus), originating in South Africa, were inoculated subcutaneously with Ebola virus (EBOV). No overt signs of morbidity, mortality, or gross lesions were noted. Bats ...
  • Isolation of a novel fusogenic orthoreovirus from Eucampsipoda africana bat flies in South Africa 
    Jansen van Vuren, Petrus; Wiley, Michael; Palacios, Gustavo; Storm, Nadia; McCulloch, Stewart D.; Markotter, Wanda; Birkhead, Monica; Kemp, Alan; Paweska, Janusz Tadeusz (MDPI Publishing, 2016-02-29)
    We report on the isolation of a novel fusogenic orthoreovirus from bat flies (Eucampsipoda africana) associated with Egyptian fruit bats (Rousettus aegyptiacus) collected in South Africa. Complete sequences of the ten ...
  • Isolation of a novel orthobunyavirus from bat flies (Eucampsipoda africana) 
    Jansen van Vuren, Petrus; Wiley, Michael R.; Palacios, Gustavo; Storm, Nadia; Markotter, Wanda; Birkhead, Monica; Kemp, Alan; Paweska, Janusz Tadeusz (Microbiology Society, 2017-05)
    The Bunyaviridae family comprises viruses causing diseases of public and veterinary health importance, including viral haemorrhagic and arboviral fevers. We report the isolation, identification and genome characterization ...
  • Marburg virus infection in Egyptian rousette bats, South Africa, 2013-2014 
    Paweska, Janusz Tadeusz; Jansen van Vuren, Petrus; Kemp, Alan; Storm, Nadia; Grobbelaar, Antoinette A.; Wiley, Michael R.; Palacios, Gustavo; Markotter, Wanda (Centers for Disease Control and Prevention, 2018)
    We detected a high seroprevalence of Marburg virus (MARV) antibodies in fruit bats in South Africa; 19.1% of recaptured bats seroconverted. The MARV RNA isolated closely resembled the 1975 Ozolin strain. These findings ...
  • Paramyxo- and coronaviruses in Rwandan bats 
    Markotter, Wanda; Geldenhuys, Marike; Jansen van Vuren, Petrus; Kemp, Alan; Mortlock, Marinda; Mudakikwa, Antoine; Nel, Louis Hendrik; Nziza, Julius; Paweska, Janusz Tadeusz; Weyer, Jacqueline (MDPI Publishing, 2019-07-02)
    A high diversity of corona- and paramyxoviruses have been detected in different bat species at study sites worldwide, including Africa, however no biosurveillance studies from Rwanda have been reported. In this study, ...
  • South African Ebola diagnostic response in Sierra Leone : a modular high biosafety field laboratory

    BACKGROUND : In August 2014, the National Institute for Communicable Diseases (NICD) in South Africa established a modular high-biosafety field Ebola diagnostic laboratory (SA FEDL) near Freetown, Sierra Leone in ...
  • A survey on West Nile and Usutu viruses in horses and birds in Poland 
    Bazanow, Barbara; Jansen van Vuren, Petrus; Szymanski, Piotr; Stygar, Dominika; Fracka, Agnieszka; Twardon, Jan; Kozdrowski, Roland; Paweska, Janusz Tadeusz (MDPI Publishing, 2018-02-17)
    West Nile virus (WNV) and Usutu virus (USUV) are members of the family Flaviviridae which, natural life cycles involve mosquito–bird–mosquito transmission. Both represent emerging viruses in Europe with potential to cause ...
