Cuterebra Larval Infestation

                  ----------------------------

                      General Information



Cuterebra flies produce larvae (small worms) that infest the skin

of rodents, squirrels, rabbits, dogs and cats.  The flies lay

eggs on the fur or in the immediate area of an animal.  After the

eggs hatch, the resulting larvae burrow into the animal's skin.

A cyst forms around the larva, and the cyst has a small hole in

the center through which the larva's head can be seen.  After

about month, the mature larva emerges from the cyst and drops to

the ground to continue its life cycle in the soil.



                 Important Points in Treatment



1.  A general anesthetic may be required for removal of the larva

    and cleaning of the wound.



2.  The larva should not be crushed while still embedded in the

    skin, because your pet could undergo a serious, shock-like

    reaction.



3.  Any bacterial infection of the cyst must be treated after the

    larva is removed.



        Notify the Doctor if Any of the Following Occur:



    * Your pet's wound enlarges or becomes painful.



    * Your pet is reluctant to eat.



    * Your pet is depressed.
