In
December 2000, an infectious disease spread through a captive breeding group
of African wild dogs (Lycaon pictus) in Tanzania, killing 49 of 52 animals within
two months. The causative agent was identified as canine distemper virus (CDV)
by means of histological examination, virus isolation, reverse transcriptase-polymerase
chain reaction (RT-PCR) analysis and nucleotide sequencing. Phylogenetic analysis
of the CDV strain involved revealed a close resemblance to isolates found in
wild and domestic carnivores in East Africa in the 1990s. Our study demonstrates
the importance of adequate protection against infectious diseases for the successful
outcome of captive breeding programs of endangered species.
