Dermatophytosis in a Jack Russell terrier

9 Dermatophytosis in a Jack Russell terrier


There are aspects of the history that might alert the clinician to the possibility of dermatophytosis. These would include: breed predispositions to dermatophytosis (see ‘Epidemiology’ section); a history of exposure to a zoophilic or geophilic source of infection, such as a terrier breed hunting hedgehogs; evidence of contagion in contact animals or lesions on the owner suggestive of zoonosis; and the onset of skin disease in an animal with no previous history of skin problems. If there is pruritus, the appearance of alopecia or scaling prior to the onset of pruritus would suggest that this was not an allergic aetiology. A poor response to glucocorticoids, antibacterial or antiparasitic therapy could also be suggestive of dermatophytosis.

The relevant aspects of the history were:


There was mild peripheral lymphadenopathy, but there were no other abnormalities on general physical examination.

Examination of the skin revealed extensive patches of relatively well-demarcated alopecia, erythema, hyperpigmentation, and crusting and scaling over the muzzle, periorbital skin, the left dorsal trunk, the lateral thighs and the forelimbs (Figs 9.1, 9.2 and 9.3).
