Borrelia spp

From Ferret

Borrelia spp are a parasitic tick-borne Gram-negative anaerobic spirochaete bacteria which causes anemia in wild mustelids.

Species which are pathogenic to mustelids include:

  • Borrelia burgdorferi sensu lato

Disease has been reported in the badger[1].

Most infected mustelids are asymptomatically infected, and co-infections with Anaplasma spp and Babesia spp are common[2].

This parasite can be transmitted to humans, where it causes Lyme disease across the USA, Europe and Asia.
