Signs and Symptoms Of Blastomycosis In Dogs

If your dog is a dog from 2 to 4 years old, he is a healthy, large-breed dog that lives in any of the valleys of the Mississippi, Missouri, and Ohio River; the countries of the Central Atlantic; southern Saskatchewan. Manitoba; Quebec. Or southern Ontario – watch out for uterine disease – is potentially fatal. It is inserted by the infectious fungi fungus blastomycosis dermatitis, which invades by inhalation.

This morphological bacterium is scattered everywhere and then turns into a deadly yeast that infects the lungs and spreads throughout the dog’s body, from the central nervous system to the brain. And the more bad news – it also affects people – but you can’t catch it from your dog. Pollution of sandy and acidic soils near freshwater bodies, such as lakes and rivers, in particular, this dangerous organism thrives on the high organic matter in the soil, a rich decomposition of decomposing wood, animal waste, and moisture, which promotes its growth.

Symptoms Blastomycosis and Types:

  • Fever
  • Anorexia (anorexia).
  • Weight loss
  • Eye secretions
  • Eye inflammation, especially the iris
  • Difficulty breathing (for example, coughing, wheezing and other unusual breathing sounds)
  • Skin lesions, which are often filled with pus

The reasons
Congenital blastomycosis usually occurs when a dog inhales airborne fungi of the genus Blastomyces dermatitidis after muddying contaminated soil. This can be from benign activity such as digging in the dirt or after the smell effect. Spores can also get through the skin. Exposure to areas with water, decomposing materials, or recently excavated areas increases the risk of fungi exposure and the consequent development of the disease.

Early detection and treatment with antifungal therapy can avoid the severe symptoms of this systemic fungal disease and provide a good prognosis if the dog is immune deficient. On the other hand, if blastomycosis goes undetected or signs of illness in a dog are neglected, the two most important negative prognostic factors are central nervous system involvement and severe lung disease. Moreover, dogs with pulmonary blastomycosis may deteriorate rapidly during the first three days of treatment. Unfortunately, the lethal outcome is 50 percent during the first seven days of treatment. Likewise, if the brain becomes infected, the dog usually dies.

What clinical signs and symptoms will I see in my dog ​​if I have blastomycosis?
Knowing the clinical signs of uterine disease sooner rather than later makes a big difference in the world for your dog.

While many dogs show only vague signs of illness, seek veterinary care right away if they show any of these common and unspecified signs of blastomycosis that occur in 40 to 60 percent of infected dogs:

  • Loss of appetite and weight loss.
  • Anorexia
  • depression
  • Idle or lack of energy.
  • Fever with a temperature above 103 degrees Fahrenheit.
  • Lung disease occurs in 65 to 85 percent of dogs with blastomycosis.

Watch for these clinical signs of your dog’s lungs at risk:

  • The practice of intolerance.
  • Coughing
  • Difficulty breathing or shortness of breath.
  • Abnormally rapid breathing (quickening of the breath).
  • Purple or bluish discoloration of the mucous membranes and skin, which is caused by tissue near the surface of the skin with low saturation with oxygen (cyanosis).
  • Lung lesions are clinically silent, so although you cannot see them, they may be present. It is usually recommended to examine chest radiography for suspected cases of blastomycosis, so ask your vet about this.

30 to 50 percent of dogs will appear with one or more enlarged peripheral lymph nodes and reactive lymphoid hyperplasia, which is the normal response of the lymph nodes to infection or inflammation.

Ocular lesions occur in 20 to 50 percent of cases of blastomycosis disease with inflammation of the inner part of the eye (endometritis) most common. To maintain vision, prompt diagnosis and aggressive treatment are required. If your dog shows any signs of blindness, don’t need to say, seek veterinary care immediately. Likewise, a long list of other ocular manifestations of uterine blastomycosis such as granulomatous retinal detachment, vitreous hemorrhage, and corneal edema heralds dangerous results if they are not detected in time and treated.

Telltale signs of uterine blastomycosis occur when the skin is affected. They appear in 30 to 50 percent of affected dogs, from skin problems such as block-like lesions and ulcerated skin lesions that drain the purulent fluids. This pattern of infection affects the nose, face, and nails.

When a solitary bone develops with the Blastomyces dermatitidis, it causes lameness, which is another easy clinical sign for blastomycosis. This occurs in up to 30 percent of infected dogs. Usually affecting the bones of the distal limbs, cytology, or biopsy is the only way to distinguish between fungal diseases and tumors. Symptoms, in this case, will be swelling of soft tissues.

How is toxoplasmosis diagnosed in dogs?
Your veterinarian will evaluate signals from your dogs such as a systemic inflammatory response and the site or sites of infection to help diagnose blastomycosis. Once an infection is suspected, several diagnostic tools are run to arrive at a final diagnosis. Complete blood count, serum chemistry, and any abnormalities are usually nonspecific but reflect chronic inflammation. Thoracic radiography is a standard for the diagnosis of uterine disease and may reveal lung lesions. Clearly identifying an organism through a cellular or histological examination of the affected tissues is also a typical diagnostic procedure that includes eye and skin lesions, which often expedites the diagnosis. In addition, serological and urinary antigen tests and PCR series seek evidence of infection.

Antigen testing and a relatively new antigen called an enzymatic immunoassay or EIA may help veterinarians diagnose uterine blastomycosis, so if uterine blastomycosis is suspected in your dog, ask your vet for availability.

Protocol for treatment and diagnosis of blastomycosis in dogs, recovery, and relapse.
A review of the symptoms and manifestations of blastomycosis disease in dogs shows that the diagnosis of this infection is protected and variable. Tragically, not all infected dogs will survive. However, despite the odds, many dogs live and have antifungals – fluconazole and itraconazole – to thank her for recovery. With relatively few side effects, these medications are administered long-term, often at least four to six months, with success in many cases. Other medications, including amphotericin B, ketoconazole, or a combination of antifungal medication therapies are also used with encouraging results in many dogs.

Nevertheless, blastomycosis is an insidious, potentially devastating disease that is likely to claim that its victims in relapse – are more common when the fungus affects the nervous system, testes, or eyes. Medicines are often ineffective in breaking through the dog’s natural defensive barriers, making the elimination of organisms from these systems more difficult. Castration may be needed to eliminate the source of the testicle for infection, and likewise, removal of one or both eyes is indicated in eye infection, especially if the dog has already been blinded by the disease.

Follow up on urinalysis using the MiraVista antigen test, evaluate the effectiveness of the treatment and is generally considered a criterion for discontinuation of the drug.

Is uterine blastomycosis infectious, and am I at risk of getting dogs?
Good news! You won’t become infected with blastomycosis directly from your dog — if you’re healthy. However, it is frequent that the same area your dog was hit with; for example, at the bank of the river or any area surrounding a freshwater body, puts you at risk of infection. Moreover, strict hygiene, such as wearing rubber gloves, is a logical idea only when dealing with and caring for any drainage lesions associated with the disease. Although it is not known that the disease is infectious to humans if your dog is diagnosed with bullous blastomycosis disease, it is wise to consult a doctor if any of the family members are:

  • Infants or children.
  • Organ transplant patients.
  • Undergo chemotherapy.
  • HIV / AIDS diagnosed.
  • Elderly
  • Immunosuppression

How long can dogs live with blastomycosis?
In treated dogs, clinical treatment can be expected in 70% of dogs, with 20% experiencing relapses from months to a year after treatment. The prognosis is best for dogs with mild disease or no lung disease, but it is worse for those with a central nervous system.
