Mucormycosis In Dogs – Symptoms, Causes & Treatment

Mucormycosis In Dogs

Mucormycosis is a general term for infections caused by a group of fungal and mold species that affect dogs. The infection has the most effect on a dog’s gastrointestinal tract and skin.

Mucormycosis is caused by a class of Glomeromycetes species that also causes zygomycetes, lagenidiosis, pythiosis, etc. Mucormycosis fungus is considered an opportunistic pathogen and dogs that have suppressed or compromised immune systems are highly susceptible.

Depending on the underlying immunosuppression of the host, the clinical presentation of mucormycosis is broad and some overlapping exists. The clinical presentation of mucormycosis can be broadly grouped into: pulmonary, cutaneous, rhinocerebral, gastrointestinal, disseminated infections, and other uncommon presentations.

Usually, canine infections occur when the fungus enters the GI tract via the blood vessels. This will decrease the flow of blood and in due course, block all blood flow to the tissues resulting in necrosis, and causing extensive damage to the tissues. If not diagnosed quickly and treated properly, the affected dog will die.

Symptoms Of Mucormycosis

  • Development of nodules/enlarged lymph nodes
  • Lesions on the skin, sometimes draining and red
  • Vomiting
  • Pain and Inflammation in affected areas of the body
  • Pneumonia or other GI problems
  • Jaundice

Treatment Options For Mucormycosis

Commonly used Anti-fungal agents are azole antifungals including itraconazole, fluconazole, voriconazole and ketoconazole. They have relatively few side effects and are well-tolerated by most dogs.

Treatment of mucormycosis requires long-term medications (2-6 months in most cases)

Amphotericin B (Abelcet -The Liposome Company) is the "gold standard" of antifungal drugs

ketoconazole(less expensive than the other azole antifungals) or a combination of medications may also used in certain cases.
