Keep reading this article where we detail how to heal wounds with worms in dogs, the best treatment for myiasis, as well as many more details.

What is myiasis, gusasnera or bichera

Myiasis, commonly known as "bichera" or "gusanera", is a type of parasitic infestation produced by dipterous insects, with two wings, such as flies, mosquitoes, horseflies and typical or mosquitoes. It can cost to identify in primary phases, especially if only they are internally, however it is easily identified when it occurs externally, as would be the case of a wound full of worms or larvae.

Insects parasitize vertebrate animals, being very common to find them in dogs, cats and farm animals. Specifically, the insects in their adult stage reproduce and deposit the eggs in the flesh of an animal, since when they are born the larvae feed on the tissue and fluids of the host animal. The larvae continue their cycle feeding, both living and dead tissues, to become pupae and then adults, at which point they leave the host to continue with their biological cycle.

Some of the most common diptera species are the following:

  • Megaselia rufipes
  • Lucilia spp
  • Calliphora spp
  • O. ovis
  • Chrysomyia albicans
  • W. magnificent
  • Phormia regina
  • S. carnaria
  • Sarcophaga spp
  • Wohlfahrtia magnifica
  • M. scalaris
  • Rhinoestrus purpureus
  • Oestrus ovis

There are species that take advantage of wounds or ulcers and others that, directly, parasitize directly through the skin or the bodily orifices, like ears or nose. Therefore, this problem can occur in any part of the body, the most common being the eyes, ears, nose, mouth, anal and genital region and any injured part.

The dogs that have easiest to suffer from this problem are those that live in areas of humid climate, since this condition facilitates the reproduction of the diptera and their survival. Also, dogs that do not have proper hygiene and health control, or are already sick, are more likely to suffer from myiasis.

If left untreated, other health problems will occur, due to the enzymes that larvae produce to feed along with the very fact that they consume the tissues. These secondary conditions can be of different types and different levels of severity, but in a matter of a short time the dog's life will be compromised .
