Anthrax in a backyard domestic dog in Ukraine: a case report.

Anthrax has been reported in domestic and wild dogs throughout much of the world. Generally, canids are considered resistant to anthrax, although there are several reports of anthrax deaths in both wild and domestic canid populations. Prior to 2012, anthrax had not been reported in dogs in Ukraine, despite a long history in livestock and wildlife. An outbreak involving at least one cow and one dog was reported from a backyard setting in southern Ukraine in August of 2012. Laboratory results and epizootic data were compiled from official investigation reports of regional and state veterinary services involved in the case response. A single dog died after being fed meat and bones from an illegally slaughtered heifer that died of anthrax 5 days earlier. On the evening of the dog's death, the dog refused food or water; however, there were no other clinical signs. Laboratory tests of dog tissue included traditional bacteriology for Bacillus anthracis, a small rodent bioassay for virulence, and immunoprecipitation tests (IPT). IPT was positive, viable B. anthracis colonies were cultured, and a bioassay confirmed virulence. This was the first confirmed case of canid anthrax in Ukraine. This case report serves to remind veterinary officials that anthrax can affect a wide number of species. We advise surveillance systems remain flexible and include animals that might not otherwise be tested.
