Breaking the News: Blastomycosis in Dogs – Contagious or Not?

Understanding Blastomycosis in Dogs

Blastomycosis is a systemic fungal infection caused by the dimorphic fungus Blastomyces dermatitidis. This fungus is commonly found in sandy, acidic soil near bodies of fresh water. The distribution of blastomycosis in North America includes the Mississippi, Missouri, and Ohio river valleys, the Middle Atlantic states, southern Saskatchewan, Manitoba, Quebec, and Ontario.

Overview of Blastomycosis

Blastomycosis primarily affects dogs and humans. Infection most commonly occurs after inhaling spores from contaminated soil. Once inhaled, the fungus transforms into a yeast form at normal canine body temperature, infecting the lungs and spreading systemically. The most common sites of infection in dogs include the lungs, lymph nodes, eyes, skin, and bone. Subclinical or spontaneously resolving infection is uncommon (dvm360).

Prevalence and Risk Factors

Certain factors increase the risk of dogs developing clinically apparent blastomycosis. Dogs between the ages of 2 and 4 years, intact males, and large breeds are at greater risk. Sporting dogs and hound breeds are particularly predisposed, likely due to increased exposure to high-risk areas during hunting. Dogs living near rivers or lakes and those with access to recently excavated sites also have an increased risk of infection. Most cases of canine blastomycosis are diagnosed in late summer or early fall (dvm360).

It’s important to note that blastomycosis is not contagious from dog to dog or from dogs to humans. It is solely caused by environmental exposure to the fungus. However, multiple pets in the same household can be affected if they are exposed to the same contaminated environment.

To identify blastomycosis in dogs, it’s crucial to recognize the signs and symptoms associated with the disease. Prompt diagnosis and appropriate treatment can significantly improve outcomes for affected dogs. Diagnostic procedures, such as laboratory tests and thoracic radiography, are employed to confirm the presence of blastomycosis and assess its extent.

Preventive Measures

When it comes to blastomycosis in dogs, prevention plays a crucial role in keeping your furry friend safe. While blastomycosis itself is not contagious from dogs to humans or other animals, it’s important to take preventive measures to minimize the risk of exposure to the fungus. This section will cover two key areas of prevention: hygiene practices and environmental considerations.

Hygiene Practices

Strict hygiene practices should be followed when handling any draining lesions or wounds of an infected dog. It is important to wear protective gloves and thoroughly wash hands after contact with an infected animal to prevent potential transmission of the fungus. By taking these precautions, you can reduce the likelihood of accidental exposure to the infectious form of the fungus.

Environmental Considerations

Blastomycosis is most prevalent in warm and moist environments, particularly along the Ohio, Missouri, Tennessee, and St. Lawrence River valleys in the United States (VCA Canada). If you live in an area with a higher incidence of blastomycosis, it’s important to be aware of the potential risk and take appropriate precautions.

Here are a few environmental considerations to help minimize the risk of blastomycosis:

1. Avoid High-Risk Areas: Be cautious when visiting areas near bodies of fresh water, particularly those with sandy, acidic soil. These environments are more likely to harbor the infective form of the Blastomyces dermatitidis fungus (dvm360). While it may not be possible to completely avoid these areas, being mindful of the risk can help reduce exposure.

2. Limit Outdoor Activities: During periods of high prevalence, such as late summer or early fall, consider limiting your dog’s outdoor activities in areas where blastomycosis is more common. This can help minimize the chances of exposure to the fungus.

3. Promptly Clean and Dry: After outdoor activities, thoroughly clean and dry your dog’s paws, especially if they have been in contact with soil or water. This can help remove any potential sources of the fungus and reduce the risk of infection.

4. Maintain Good Ventilation: Ensuring proper ventilation in your dog’s living areas, such as kennels or crates, can help reduce the buildup of moisture. Blastomyces dermatitidis thrives in moist environments, so good airflow can help create an unfavorable environment for the fungus.

By implementing these preventive measures, you can significantly reduce the risk of blastomycosis in your dog. However, if you suspect your dog may have been exposed or if you notice any signs of blastomycosis, it’s important to seek veterinary care promptly.
