Fungal Disease (Sporotrichosis) of the Skin in Dogs
Sporotrichosis in Dogs
Sporotrichosis is a fungal disease that affects the skin, respiratory system, bones and sometimes the brain. Infection is caused by the virtually ubiquitous dimorphic (mold and yeast) fungus, Sporothrix schenckii, which typically infects via direct inoculation - that is, through abrasions of the skin or by inhalation. The origin of the fungus is environmental; it is naturally found in soil, plants and sphagnum moss, but it can be communicated zoonotically between different animal species, and between animals and humans.
In dogs, the disease occurs more commonly in hunting dogs because of the increased likelihood of puncture wounds associated with thorns or splinters.
Symptoms and Types
Your veterinarian will perform a thorough physical exam on your dog, taking into account the background history of symptoms and possible incidents that might have led to this condition. A complete blood profile will be conducted, including a chemical blood profile, a complete blood count, and a urinalysis.
It is important to note that this is a zoonotic disease, meaning that it is communicable to humans and other animals, and proper precautions will need to be taken to prevent the spread of infection. Even if you do not have a break in your skin, you are not protected against acquiring the disease.
An examination of the fluid from the lesions is often necessary to confirm an infection. In dogs, special fungal stains may aid in the diagnosis, but a negative finding does not rule out the disease. Laboratory cultures of the deeply affected tissue often require surgery to obtain an adequate sample. These samples will be sent for analysis, along with a special note to the laboratory listing sporotrichosis as a differential diagnosis. Secondary bacterial infections are common.
