Camelidae and Cervidae Fungal Skin Diseases – NAVLE Study Guide

Overview and Clinical Importance

Fungal skin diseases in camelids (llamas, alpacas) and cervids (deer, elk) represent an important but often underdiagnosed category of integumentary disorders. These infections range from superficial dermatophytoses to life-threatening systemic mycoses. Understanding these conditions is essential for the NAVLE, particularly given the increasing popularity of camelids as companion and fiber animals and the importance of cervids in wildlife medicine.

The unique integumentary characteristics of these species, including the dense fiber coat of camelids and the seasonal pelage changes in cervids, create distinct microenvironments that influence fungal colonization and disease expression. Additionally, camelids appear to have heightened susceptibility to certain endemic mycoses, particularly coccidioidomycosis in endemic regions.

Dermatophytosis (Ringworm)

Etiology and Pathogenesis

Dermatophytosis is a superficial fungal infection of keratinized tissues caused by dermatophyte fungi that utilize keratin as a nutrient source. In camelids and cervids, dermatophytosis is considered uncommon to rare, with only sporadic case reports in the literature. The primary causative agents include:
