Myiasis: the so-called Bicheira in the dog

Myiasis is a parasitic disease consisting of infestation of the host (man, dog, cat, etc) by larvae of dipterans, that is, flies. There are different species of flies that may be involved in this disease, being the most common in dogs: the fly of the family Calliphoridae , in particular the species Cochliomyia hominivorax that causes cavitary myiasis, known as bicheira and the fly of the family Cuterebride, mainly of the species Dermatobia hominis that causes primary furunculoid myiasis, also called Berne .

We can classify the myiases, according to their location, into three different types :

  • Cutaneous : on the skin, by deposit of fly eggs.
  • Cavitary : in the cavities (nasal, oral, auditory, orbital, etc.) by deposit of fly eggs.
  • Intestinal : in the intestine, by ingestion of food contaminated with larvae.

Myiasis in the dog’s mouth

The myiasis in the dog ‘s mouth is a very common situation. It is very painful for the animal, which normally stops eating due to pain, eventually losing enough weight.

If you have a dog with this problem, or saw a mutt on the street with pussy, contact an animal association if you can not even seek veterinary help for it. It is a very painful situation, and the dog is certainly suffering a lot.

Myiasis in the ear of the dog

Another very common place for eggs to be deposited by flies is the dog’s ears. The myiasis in the dog’s ear is also very painful and needs urgent veterinary treatment, mainly because the larvae begin moving the ear canal and can have serious consequences.

Myiasis in the dog’s eye

Sometimes, this problem occurs in the eyes of the dog, and the flies deposit the eggs in this place and the larvae feed on the tissue of that area. Some animals may become blindbecause the larvae eat all the ocular tissue. Thus, it is essential that you do not let the problem go if you see one of these maggots in your dog’s eye. And above all, do not try to remove the larvae yourself as it is very painful for the animal and the eyes are very sensitive areas. The dog will need to be sedated in order to be able to perform the procedure with the least possible pain and without risk to the one who does it.

With due veterinary treatment, it is possible to save and recover the animal, even if they are in an advanced state like the dog we can see in the image.

Myiasis in cats

Although it is less common than in dogs, there are cases that report the onset of myiasis in cats . This problem usually affects short-haired cats more, because flies have better access to the animal’s skin.

Cats that have access to the street are more likely to have this problem since they have more contact with dirty places where these flies are. You should be especially aware if your cat is an uncastrated male and that they spend a few days on the street and get involved in fights with other cats. The small wounds and lesions resulting from these fights are the place of choice for flies to lay their eggs.

Symptoms of myiasis in dogs and cats

The most common symptom of this disease is the skin lesions caused by the larvae. Usually these lesions have a repulsive odor. In addition, it conforms to the location of myiasis, other symptoms may occur simultaneously:

  • peritonite
  • lameness
  • blindness
  • dental problems
  • anorexia (the animal stops eating)
  • weight loss

The symptoms of this disease can reach such a serious state that the animal may even end up dying of toxemia, hemorrhage or secondary infections.

Myiasis in puppy – treatment

This disease is very traumatic for the dog. Sometimes the larvae even reach deep areas of the skin and remove them manually causes a lot of pain in the dog, and it is necessary to anesthetize it. For this reason, it is imperative that the treatment is duly carried out by a veterinarian.

How to treat myiasis in dogs

The veterinarian starts by shaving and disinfecting the affected area and removes the lavas with forceps. Administration of systemic and / or local antibiotics may also be required . In addition, larvicides may be used and supportive therapy may be required .

How to prevent to look at yourself

The main thing is to be alert and examine your dog daily in the most common places for the appearance of this problem (mouth ear, eyes), especially in the case of dogs that spend a lot of time away from home. As soon as you detect any signs or observe a larva, take your dog to the veterinarian immediately. This is a problem that develops very quickly. Remember that the larvae literally eat the flesh of your dog!

The hygiene of the place where the dog lives is the most important to prevent the appearance of these flies in the place where the dog lives. Garbage, feces, food, attract all kinds of flies, which deposit the larvae on the dog. See also our article on how to ward off dog flies .

Generally, the flies deposit the larvae in small wounds of the dog. Therefore, if your puppy has a wound, disinfect properly , to avoid this problem.

Exactly the same applies in case you have a feline. Sandbox hygiene is very important to prevent the appearance of flies. And if the cat has a wound , you should clean it properly.
