Anaplasma spp

From Ferret
Anaplsma spp in blood

Anaplasma spp are a zoonotic rickettsial parasitic tick-borne bacteria of wild mustelids.

Anaplasmosis occurs predominantly in North America and is transmitted by Amblyomma spp and Dermacentor spp ticks.

Species which are pathogenic to mustelids include:

  • Anaplasma phagocytophilum[1]

Coinfections with Borrelia spp and the protozoa Babesia spp have been reported[2].

Most cases of infection are asymptomatic, although this parasite can cause anemia in wild badgers and marten[3].

Treatment is usually effective with broad-spectrum antimicrobials such as doxycycline.
