Pyoderma in Cats

Pyoderma is a bacterial infection of the skin which appears as pus-filled lesions. These lesions are most often caused by Staphylococcus intermedius. Pyoderma is characterised by the location of the lesions and is called either surface or deep pyoderma.

  1. Types

    • Surface pyoderma lesions are located on top of the skin and are the most common form of Pyoderma; deep pyoderma is found in the underlying tissues and in skin folds.

    Causes

    • Pyodermas are usually the result of a flea bite allergy or food allergy, but can also be the sympton of an underlying medical condition such as hypothyroidism or hyperadrenocorticism.

    Symptoms

    • Pyoderma causes intense itching; you will notice small pus filled pimples and the skin will have dried exudate from the pustules.You may also notice patches of hair loss. In cases of deep pyoderma, you cat may exhibit pain and a general lethargy.

    Diagnosis

    • For surface pyodermas, a clinical exam is usually sufficient for diagnosis; however, for recurrent or deep pyodermas your veterinarian may perform skin scrapings, biopsies, blood tests and microscopic examination of the bacteria to determine the underlying cause. He may also culture the bacteria to determine the best antibiotic for treatment.

    Treatment

    • Your veterinarian will prescribe a long-term course of antibiotics and possibly topical medications as well. It is important to maintain a course of antibiotics for at least 21 to 30 days to ensure complete recovery.

    Follow-up

    • A medicated shampoo containing benzoyl peroxide or chlorhexadine can be used to enhance recovery and to reduce recurrence. Since there is a chance of the bacteria reaching the bloodstream, it is important to follow the treatment plan and to ensure that the treatment is successful.
