Hydranencephaly in newborn calves in Zambia.
TLDR
Hydranencephaly without arthrogryposis was observed in three newborn Holstein-Friesian calves, born during one week in a 400-cow dairy herd in Zambia, and Akabane virus infection was suspected based on the pathological findings and etiological data, however, it could not determine the exact causative agent.Abstract:
Hydranencephaly without arthrogryposis was observed in three newborn Holstein-Friesian calves, born during one week in a 400-cow dairy herd in Zambia. The affected calves were blind and exhibited nystagmus and depressed behavior. Akabane virus infection was suspected based on the pathological findings and etiological data, however, we could not determine the exact causative agent.read more

Genetic diversity and reassortments among Akabane virus field isolates.
TL;DR: Of the three RNA segments, the M RNA segment encoding the glycoproteins that induce neutralization antibodies was the most variable among the isolates, indicating genomic reassortment events among AKAV field isolates.

TL;DR: Hydranencephaly with porencephalic cavitation of the cerebellum was diagnosed, over a 2-year period, in five calves from an 80-cow herd, and Bovine virus diarrhea-mucosal disease antigens were found in the tissues of two calves.
