Leptotrombidium spp

From Dog
Larval stage Leptotrombidium[1]

Leptotrombidium spp are an hematophagous parasitic mite occasionally reported to cause infestations in dogs.

The larval form (chiggers) feeds on rodents, but also occasionally humans and dogs across South-east Asia.

Species which are pathogenic to dogs include:

  • Leptotrombidium subqunadratum
  • Leptotrombidium akamushi
  • Leptotrombidium deliense
  • Leptotrombidium pallidum
  • Leptotrombidium scutellare

These parasites affect many mammals including humans[2] and in dogs is characterized by intense pruritus and secondary dermatitis[3].

Treatment is relatively effective with acaricidal drugs such as fipronil, imidacloprid or permethrins.
