  • 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 ...
  • Mortlock, Marinda; Dietrich, Muriel; Weyer, Jacqueline; Paweska, Janusz Tadeusz; Markotter, Wanda (MDPI, 2019-01)
    The Egyptian rousette bat (Rousettus aegyptiacus) has previously been implicated as the natural host of a zoonotic rubulavirus; however, its association with rubulaviruses has been studied to a limited extent. Urine, ...
  • 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 ...
  • 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). ...
  • Weyer, Jacqueline; Szmyd-Potapczuk, Anna Victoria; Blumberg, Lucille Hellen; Leman, Patricia A.; Markotter, Wanda; Swanepoel, Robert; Paweska, Janusz Tadeusz; Nel, Louis Hendrik (Elsevier, 2011-01)
    Rabies remains a global public health problem but increasingly so in the developing world. Given a lack of awareness, priority and diagnostic capability, very few developing countries, especially in Africa, report on ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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, ...
  • Jansen van Vuuren, Petrus; Shalekoff, Sharon; Grobbelaar, Antoinette A.; Archer, Brett N.; Thomas, Juno; Tiemessen, Caroline T.; Paweska, Janusz Tadeusz (BioMed Central, 2015-10-06)
    BACKGROUND : Rift Valley fever (RVF) is a mosquito-borne viral zoonosis affecting domestic and wild ruminants, camels and humans. Outbreaks of RVF are characterized by a sudden onset of abortions and high mortality amongst ...

    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 ...
  • Dietrich, Muriel; Kearney, Teresa; Seamark, E.C.J. (Ernest); Paweska, Janusz Tadeusz; Markotter, Wanda (Royal Society Publishing, 2018)
    Seasonal reproduction is a period of extreme physiological and behavioural changes, yet we know little about how it may affect host microbial communities (i.e. microbiota) and pathogen transmission. Here, we investigated ...
