FUT1 and infection: The specificity with which the CDV H gene interacts with signaling lymphocytic activation molecule (SLAM) receptors and its potential as a determinant of host range has been investigated [19], probably enabling the natural infection of noncanid hosts, as the outbreaks in breeding colonies of rhesus macaques (M. mulatta) and cynomolgus macaques (Macaca fascicularis) have raised several concerns of a potential zoonotic risk of CDV in humans [15].
