Haemato-biochemical and trichographic studies on mucocutaneous lesions in dogs

Abstract

The present study was carried out with the objective of assessment of haematobiochemical and trichographic features of mucocutaneous lesions in dogs. Dogs presented with mucocutaneous lesions associated with various dermatological conditions were included in the study. Mange, atopic dermatitis, dermatophytosis, juvenile cellulitis, pyoderma and hypothyroidism with secondary Malassezia dermatitis were presented with mucocutaneous lesions in the perioral, periorbital and in the nostrils with least involvement of anogenital region. Haemato-biochemical analysis revealed anaemia, non-significant increase in total leucocyte count, neutrophilia, eosinophilia, elevated platelet count, hyperproteinaemia and hypoalbuminaemia. Elevated serum C-reactive protein was evident in all cases. Trichographic features revealed that highest number of hairs were included in the telogen phase of hair cycle with greater number of primary hairs. Hair fractures were evident in 20.8 per cent of hairs and trichoptilosis of hair tip was observed in 50.8 per cent of hairs studied. Demodex mites could be detected by hair pluck examination in all cases of demodicosis.
