| Summary: | Incidence of mycotic dermatitis among the total canine
cases presented at the University Veterinary ,Hospitals,
Kokkalai and Mannuthy for a period from September 1996 to
August 1998 was found to be 5.13 per cent. Among the total
dermatological
disorders
28.72 per cent had mycotic
dermatitis. Age, breed and sex wise incidence were collected.
This showed an increased incidence in adult dogs, mostly in
German Shepherds and that too in females.
Detailed clinical
examination revealed scaliness,
alopecia, pruritus and erythema in all cases. Lesions were
r:'
mainly localized, extremely variable in configuration and
majority were distributed on head and limbs.
Skin scrapings collected and examined under microscope
showed the presence of ectothrix arrangement of fungal spores.
Mean total and differential count of leukocytes were found to
be within the normal range for all cases.
A total of four dermatophytes and 17 non-dermatophytes
were isolated by fungal culture. Dermatophytes isolated were
three Microsporum gypseum and one Trichophyton mentagrophytes
spp. Non-dermatophytes isolated were eight Penicillium, six
Aspergillus and three Rhizopus spp.
In vitro antifungal susceptibility tests on the fungal
isolates obtained showed a high sensitivity to cinnamon oil at
a dilution of 1 in 10, followed by ketoconazole at 20 ~g and
Sphaeranthus indicus extract at 50 mg concentrations.
Response to treatment trials conducted on dogs with
mycotic dermatitis using ketoconazole o i.nt.ment; showed
therapeutic response in five out of seven cases. No response
was noticed in dogs even after the course of tr~atment with
S. indicus extract. Complete recovery was noticed in all
animals treated with cinnamon oil.
