DNA
Papillomavirus
Virus associated with Bowens in situ SCC
FcaPV-2 (3, 4 less common)
FeLV
(+/- FIV)
Virus that causes cutaneous horns on feline pads, eyelids
FeLV
FIV transmission
Bite wounds
(vertical transmission is rare)
IHC stain for FeLV
gp70
Dermatologic lesions associated with FIP
Erythema, ulcers on head and neck. Vasculitis
(Uveitis, respiratory disease, peritonitis)
Histopathology of cutaneous findings from FIP
Vasculitis
Viral Ag in blood vessel walls
T or F: Canine Distemper virus is reportable
TRUE
Dermatologic sign of canine distemper virus
Hard pad disease
*Nasodigital hyperkeratosis
*Impetigo in young puppies
Histopath of canine distemper virus
Orthokeratotic + parakeratotic hyperkeratosis
Cytoplasmic inclusion bodies (rare nuclear inclusions)
IHC shows virus in haired skin, foot pads
Clinical signs of feline calicivirus
*Vesicles in mouth, nasal –>ulcers
*Sneezing, conjunctivitis
*Transient feline limping syndrome (resolves in a few days)
*Hemorrhagic/virulent form: 30-50% mortality 2’ sepsis. More common in adults
Diagnosis of feline calicivirus + histopath findings
PCR test: swab oropharynx or conjunctiva
Histopath: epidermal necrosis, ballooning degeneration of KCs, vasculitis
Which species can develop Cowpox?
Cats!
ZOONOTIC- reportable. Fatal to immunocompromised humans
Transmission of feline poxvirus
Direct (wounds from rodents) fomites
Reservoir for feline poxvirus
Rodents
Seasonality of feline poxvirus
More common in summer, fall when there is a higher rodent population
Cutaneous lesions of feline poxvirus
Pocks = crater-like skin lesions
“Necro-ulcerative dermatitis”
Primary: Ulcerated nodule on head, neck, forelimb
Secondary lesion (nodules ulcerate and develop into): craters with crust
(possible oral vesicles, 20%)
Prognosis of feline poxvirus in exotic felids
Fatal pneumonia
Treatment for feline poxvirus
None. AVOID GLUCOCORTICOIDS
Clean with disinfectants, bleach
Scarring permanent, Lesions heal over 4-5w
Which small animal species have reported orf
Dogs (rare), 1 cat
Pack of hounds that fed on sheep carcasses
Main species = ovine, caprine
T or F: Most cats that recover from feline herpesvirus become carriers
True. 80% shed intermittently lifelong
Where does the herpesvirus live in the cat (nerve)?
Trigeminal ganglion
Cutaneous signs of feline herpes virus
Ulcers on nasal planum, bridge of nose, periocular, trunk, footpads
Are adult or kittens more often affected by feline herpesvirus dermatitis
Adults
