2019
Molini, Umberto(University of Namibia Faculty of Agriculture and Natural Resources School of Veterinary Medicine) | Aikukutu, Gottlieb(Central Veterinary Laboratory) | Kabajani, Juliet(International Atomic Energy Agency Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture) | Khaiseb, Siegfried(Central Veterinary Laboratory) | Cattoli, Giovanni(International Atomic Energy Agency Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture) | Dundon, William G.(International Atomic Energy Agency Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture)
Between July and September 2017, samples collected from six unvaccinated chickens in Namibia were shown to be positive for infectious bursal disease virus (IBDV) by RT-PCR. Partial sequence and phylogenetic analysis of the VP1 and VP2 genes from six viruses revealed that they all belong to the very virulent pathotype (Genogroup 3) and are genetically very similar to IBDVs identified in neighbouring Zambia. This is the first molecular characterisation of IBDV in Namibia and has implications on the control and management of the disease in the country.
