Abolnik, Celia; Mubamba, Chrisborn; Dautu, George; Gummow, Bruce (American Society for Microbiology, 2017-08-24)The first complete genome sequence of an African-origin Newcastle disease virus belonging to genotype XIII is described here. The virulent strain chicken/ Zambia/Chiwoko/2015 was isolated from diseased chickens in 2015.

(Daniel); Petty, Deryn (BioMed Central, 2019-12-18)BACKGROUND : The threat of poultry-origin H6 avian influenza viruses to human health emphasizes the importance of monitoring their evolution. South Africa’s H6N2 epidemic in chickens began in 2001 and two co-circulating ...
-
Abolnik, Celia (Elsevier, 2014-06)Recent reports of the detection of the zoonotic low pathogenic avian influenza (LPAI) H7N9 viruses in healthy pigeons have again put the spotlight on the potential role of pigeons and doves in the transmission of avian ...
