  • Use of Ir192 interstitial brachytherapy for an equine malignant dermal schwannoma 
    Saulez, Montague Newton; Voigt, A.; Steyl, Johan Christian Abraham; Van Wilpe, Erna; Kotzen, J.; Daniels, F. (South African Veterinary Association, 2009-12)
    A 10-year-old Hanoverian mare was evaluated for a right buccal swelling that recurred 3 months following surgical resection. Ultrasonographic examination showed a broadly pedunculated subcutaneous mass at the level of ...
  • Shuni virus as cause of neurologic disease in horses 
    Van Eeden, Charmaine; Williams, June Heather; Gerdes, Truuske G.H.; Van Wilpe, Erna; Viljoen, Adrienne; Swanepoel, Robert; Venter, Marietjie (Coordinating Center for Infectious Diseases, Centers for Disease Control and Prevention, 2012-02)
    To determine which agents cause neurologic disease in horses, we conducted reverse transcription PCR on isolates from of a horse with encephalitis and 111 other horses with acute disease. Shuni virus was found in 7 ...
  • Sarcocystis oreamni, n. sp. (Apicomplexa : Sarcocystidae) from the mountain goat (Oreamnos americanus) 
    Calero-Bernal, Rafael; Van Wilpe, Erna; White, Kevin; Verma, Shiv Kumar; Cerqueira-Cezar, Camila K.; Dubey, Jitender P. (Springer, 2015-11)
    Numerous species of Sarcocystis have been reported from wild ruminants but none has been named from the Rocky Mountain goat (Oreamnos americanus). Mature sarcocysts were found in frozen muscle samples of three of seven ...
  • Sarcocystis heydorni, n. sp. (Apicomplexa : Sarcocystidae) with cattle (Bos taurus) and human (Homo sapiens) cycle 
    Dubey, Jitender P.; Van Wilpe, Erna; Calero-Bernal, Rafael; Verma, Shiv Kumar; Fayer, Ronald (Springer, 2015-11)
    Cattle (Bos taurus) are intermediate hosts for four species of Sarcocystis, S. cruzi, S. hirsuta, S. hominis, and S. rommeli. Of these four species, mature sarcocysts of S. cruzi are thin-walled (< 1μm) whereas S. hirsuta, ...
  • Sarcocystis mehlhorni n. sp. (Apicomplexa : Sarcocystidae) from the black-tailed deer (Odocoileus hemionus columbianus) 
    Calero-Bernal, Rafael; Verma, Shiv Kumar; Cerqueira-Cezar, Camila K.; Schafer, Laurence M.; Van Wilpe, Erna; Dubey, Jitender P. (Springer, 2015-12)
    Infection with Sarcocystis is common in many species of wild cervids but none is reported from the black-tailed deer (Odocoileus hemionus columbianus). Here, we report Sarcocystis infection in two black-tailed deer ...
  • Sindbis and Middelburg old world alphaviruses associated with disease in horses, South Africa 
    Van Niekerk, Stephanie; Human, Stacey; Williams, June Heather; Van Wilpe, Erna; Pretorius, Marthi Andréa; Swanepoel, Robert; Venter, Marietjie (Centers for Disease Control & Prevention, 2015-12)
    Old World alphaviruses were identified in 52 of 623 horses with febrile or neurologic disease in South Africa. Five of 8 Sindbis virus infections were mild; 2 of 3 fatal cases involved co-infections. Of 44 Middelburg ...
  • Ultrastructure of Sarcocystis bertrami sarcocysts from a naturally infected donkey (Equus asinus) from Egypt 
    Dubey, Jitender P.; Van Wilpe, Erna; Verma, Shiv Kumar; Hilali, M. (Cambridge University Press, 2016-01)
    There is considerable confusion concerning Sarcocystis species in equids. Little is known of Sarcocystis infections in donkeys (Equus asinus). Here we describe the structure of Sarcocystis bertrami-like from the donkey by ...
