Echidnophaga spp are an hematophagous stick-fast flea of dogs found worldwide[1].

Species which are pathogenic to dogs include:

  • Echidnophaga gallinacea[2]

Clinical signs of parasitism in dogs include pruritus, alopecia, lichenification (blackening) and dermal corrugations in chronic cases.

As well as being skin parasites, they transmit proteobacteria such as Bartonella spp, haemoplasmas such as Babesia spp, Rickettsia spp and tapeworms such as Dipylidium spp.

Treatment is usually effective with a range of insecticidal drugs.

Anthelmintic treatment with praziquantel is recommended as most dogs have concurrent cestode infections.
