Cuterebriasis is a parasitic disease affecting rodents, lagomorphs (hares, rabbits, pikas), felines, and canines.
The etiologic agent is the larval development of botflies within the Cuterebra or Trypoderma genera, which occurs obligatorily in rodents and lagomorphs, respectively.
Felines and canines serve as accidental hosts, but research suggests only by Trypoderma spp.
Entrance into the body by first-instar larvae occurs via mucous membranes of natural orifices or open wounds as opposed to direct dermic penetration.
Three forms in which cuterebriasis may present in canines and felines:[1] Definitive diagnosis can only occur with positive identification of the larvae.
