Abstract
Most fungal species are commensals, not pathogenic for plants, humans, or animals. However, several species from genera Alternaria, Aspergillus, Trichophyton and Microsporum are common causes of disease, even for immunocompetent individuals, contributing to skin barrier impairment. A total of 68 allergic dogs were selected from a veterinary dermatology and allergy outpatient consultation, for conditions related to Malassezia overgrowth or other fungal complications. Allergy diagnosis was made through anamnestic and clinical criteria and allergy-implicated species were identified by intradermal testing (IDT) and serum determination of specific immunoglobulin E (sIgE). Dermatophagoides farinae, Dactylis glomerata and Malassezia pachydermatis showed as the higher sensitization species from each group. Significant correlations at p<0.05 were found between Dactylis glomerata and Phleum pratense grass pollens, Dermatophagoides farinae and Dermatophagoides pteronyssinus, Acarus siro, Tyrophagus putrescentiae and Lepidoglyphus destructor dust/storage mites, and between fungi like Aspergillus mix and Penicillium or Alternaria alternata. A significant correlation was also found between sensitization to Aspergillus mix and D. farinae, D. pteronyssinus or A. siro. Rather severe dermatitis was observed where positive IDT to Malassezia pachydermatis was found, regardless of the presence of circulating sIgE, allowing us to perceive the usefulness of both sIgE and IDT for allergy diagnosis to fungi.
