Understanding Blastomycosis in Cats
Blastomycosis is a fungal infection caused by the fungus Blastomyces dermatitidis. It is commonly found in soil around bodies of water in Eastern North America (Vetster). Cats can contract the infection through various routes, including ingestion or inhalation of the fungal spores or direct entry into the bloodstream through a skin wound (PetMD). Both indoor and outdoor cats can be affected as the spores are airborne and can spread in the environment (PetMD).
Causes of Infection
The primary cause of blastomycosis in cats is the inhalation of aerosolized spores of the Blastomyces dermatitidis fungus. Areas with high moisture near water, such as river basins and wet environments like streams, lakes, or swamps, are preferred habitats for the fungus. Cats with access to these environments are at a higher risk of infection.
Transmission Routes
Cats can acquire blastomycosis through different transmission routes. The most common way is by ingesting or inhaling the fungal spores. Cats may come into contact with the spores while exploring outdoor environments or through activities such as hunting. Inhalation of the spores leads to the infection taking hold in the respiratory system (PetMD).
In addition to inhalation, blastomycosis can also be transmitted directly into a cat’s circulation through a skin wound. If the fungus enters the body through a cut or wound, it can cause infection and spread throughout the system. However, this route of transmission is less common compared to inhalation or ingestion of spores (PetMD).

Symptoms and Diagnosis
Recognizing the symptoms of blastomycosis in cats is crucial for early detection and treatment. Understanding the clinical signs and diagnostic procedures can help in identifying and managing this fungal infection.
Clinical Signs in Infected Cats
Cats infected with blastomycosis can exhibit a range of symptoms that may vary in severity. Some common clinical signs in infected cats include:
- Weight loss
- Lethargy
- Coughing
- Decreased appetite
- Difficulty breathing
- Nasal discharge
- Eye issues
- Enlarged lymph nodes
- Skin lesions
- Fever
- Neurologic changes
The time between exposure to the organism and the onset of clinical signs typically ranges from 5 to 12 weeks (PetMD). Prompt veterinary attention is essential if your cat shows any of these symptoms to improve the prognosis.
Diagnostic Procedures
Diagnosing blastomycosis in cats can be challenging, and it often requires a combination of clinical presentation, laboratory tests, and imaging studies. While diagnosis in cats is generally made through visualization of fungal organisms in infected tissues under the microscope, it is important to note that data on diagnostic tests specifically for cats are limited.
To confirm the presence of blastomycosis, your veterinarian may perform the following diagnostic procedures:
- Microscopic examination: A microscopic examination of infected tissues, such as skin lesions or respiratory secretions, can reveal the presence of fungal organisms.
- Fungal culture: Culturing a sample from the affected area can help identify the specific fungal strain responsible for the infection.
- Serology: Blood tests can detect antibodies produced by the cat’s immune system in response to blastomycosis. However, serology tests may not be as accurate in cats as they are in dogs.
- Imaging studies: X-rays or other imaging techniques may be used to evaluate the lungs and other affected areas. These can help identify characteristic patterns associated with blastomycosis.
Due to the challenges in diagnosing blastomycosis in cats, it is crucial to work closely with your veterinarian and provide them with a detailed medical history and any relevant information about your cat’s environment and potential exposure.
By recognizing the clinical signs and utilizing appropriate diagnostic procedures, veterinarians can accurately diagnose blastomycosis in cats and initiate the necessary treatment to improve the cat’s health and well-being.
Treatment Approaches
When it comes to treating blastomycosis in cats, a multi-faceted approach is necessary to effectively combat the infection. This typically involves the use of antifungal medications, along with careful monitoring for any potential side effects.
Antifungal Medications
The primary treatment for feline blastomycosis involves a prolonged course of oral antifungal medications. The most commonly used medication for blastomycosis treatment in both cats and dogs is itraconazole. It is considered the treatment of choice due to its effectiveness against the fungal infection (PetMD).
In some cases where the infection is advanced or not responding to itraconazole alone, combination therapy with other antifungal medications may be necessary. The goal is to target the blastomycosis fungus and eliminate it from the cat’s system. The specific combination of medications will be determined by the veterinarian based on the severity and response to treatment.
Side Effects and Monitoring
While antifungal medications are effective in treating blastomycosis, they can also have potential side effects on the liver and gastrointestinal system. It is crucial for veterinarians to closely monitor a cat’s liver enzymes and other body functions through routine bloodwork and urine testing during and after the treatment period (PetMD).
Regular monitoring helps detect any adverse reactions to the medication and allows for timely adjustments to the treatment plan if needed. It is important to strike a balance between effectively treating the infection and minimizing the risk of medication-related complications. The veterinarian will determine the appropriate dosage and frequency of medication based on the cat’s individual needs and response to treatment.
By closely following the prescribed treatment plan and ensuring regular monitoring, the veterinarian can assess the cat’s progress and make any necessary adjustments to optimize the treatment outcome.
