Read the first 7 Feline Infectious flashcards as text

  1. A cat tests positive on FIV ELISA. The cat is 8 weeks old and was born to a seropositive queen. How should this result be interpreted?

    Answer: Likely maternal antibody transfer; retest after 6 months of age

    FIV ELISA detects antibodies, and kittens can carry maternally derived antibodies until 6 months of age, yielding false-positive results.

  2. Ringworm in cats is most commonly caused by which dermatophyte species?

    Answer: Microsporum canis

    Microsporum canis accounts for approximately 90% of feline dermatophytosis cases and is also the predominant zoonotic species from cats.

  3. Which form of feline upper respiratory infection is most likely to cause chronic rhinosinusitis as a sequela following acute infection?

    Answer: Feline herpesvirus-1 infection

    FHV-1 establishes latency in the trigeminal ganglion and can cause turbinate destruction leading to chronic rhinosinusitis after reactivation episodes.

  4. A cat presents with bilateral anterior uveitis. FIP testing is negative. Which other infectious agent should be high on the differential list?

    Answer: Toxoplasma gondii

    Toxoplasma gondii is a leading cause of feline uveitis and should be tested via serology when FIP is ruled out.

  5. A cat is presented with a nasal mass and skin nodules; cytology reveals large encapsulated yeast with narrow-based budding. What is the most likely diagnosis?

    Answer: Cryptococcosis

    Cryptococcus neoformans/gattii appears as large encapsulated yeasts with narrow-based budding on cytology and commonly causes nasal and skin lesions in cats.

  6. Feline calicivirus virulent systemic strain (VS-FCV) outbreaks are characterized by which distinctive clinical sign NOT typical of classic FCV?

    Answer: Subcutaneous edema and facial swelling

    VS-FCV causes severe systemic disease including facial and limb edema, skin ulceration, and high mortality, distinguishing it from classical FCV.

  7. Which of the following best describes the mechanism by which FeLV causes non-regenerative anemia in some infected cats?

    Answer: Direct viral infection of erythroid precursors in bone marrow causing myelosuppression

    FeLV directly infects erythroid progenitor cells in the bone marrow, impairing red blood cell production and causing non-regenerative anemia.
