Read the first 7 Feline Infectious flashcards as text

  1. A cat presents with corneal sequestrum and chronic ocular discharge. Which herpesvirus is most commonly implicated in this condition?

    Answer: Feline herpesvirus-1

    Feline herpesvirus-1 (FHV-1) is strongly associated with corneal sequestrum formation due to chronic corneal inflammation and ulceration.

  2. Which feline coronavirus (FCoV) mutation is classically associated with the transition from enteric infection to feline infectious peritonitis (FIP)?

    Answer: 3c gene loss-of-function mutation

    Loss-of-function mutations in the 3c gene of feline enteric coronavirus are associated with the shift to macrophage tropism and development of FIP.

  3. A 3-year-old intact male cat tests FIV-positive. What is the most reliable route of transmission for this virus?

    Answer: Bite wounds

    FIV is most efficiently transmitted through bite wounds because high viral loads are present in saliva.

  4. Feline panleukopenia virus (FPV) primarily targets which tissue due to its requirement for rapidly dividing cells?

    Answer: Intestinal crypt epithelium

    FPV targets rapidly dividing intestinal crypt cells, leading to villous collapse, malabsorption, and severe hemorrhagic enteritis.

  5. A cat with confirmed FeLV infection is most likely to develop which neoplastic condition?

    Answer: Multicentric lymphoma

    FeLV strongly predisposes cats to multicentric lymphoma, particularly T-cell lymphoma in young cats.

  6. Which antifungal is the treatment of choice for feline cryptococcosis affecting the CNS?

    Answer: Fluconazole

    Fluconazole achieves excellent CNS penetration and is the preferred long-term treatment for feline cryptococcal meningoencephalitis.

  7. A cat from a shelter presents with vesicular oral lesions and limping. Which pathogen is most likely responsible?

    Answer: Feline calicivirus

    Feline calicivirus causes oral ulcerations and acute lameness syndrome (virulent systemic FCV strains), distinguishing it from FHV-1 which rarely causes limb disease.
