Synosternus spp

From Dog
Adult Synosternus pallidus

Synosternus spp are a common hematophagous parasitic rhopalopsyllid flea which is commonly found on rodents but has been reported on hunting dogs[1] or dogs living in close proximity to domestic rabbits.

These fleas, primarily a parasite of small mammals, infect dogs as an accidental host[2].

Species which are pathogenic to dogs include:

  • Synosternus pallidus[3]

Clinical signs include pruritus and localized dermatitis associated with flea activity.

Transmission of Rickettsia spp has been reported[3].

Treatment is usually effective with a range of insecticidal drugs such as fipronil and permethrins.
