Systemic Candida albicans Infection in Two Alpacas (Lama pacos)

Systemic Candida albicans infection was diagnosed in two adult alpaca stallions originating from different herds. Case I had a history of chronic dermatitis with unknown aetiology that had been treated long-term with glucocorticolds. Case 2 had suffered from transient facial paralysis and psoroptic mange of the external ear. Both animals died sudden]), after recovering from their initial disorders. Necropsy examination of case 1 revealed multifocal erosive dermatitis, thoracic and abdominal serofibrinous effusions, and Multiple Suppurative foci In lung, myocardium, kidney, pancreas and brain. Case 2 had multiple ulcers of the third gastric compartment and local suppuratiave nephritis. Additionally, moderate depletion of lymphoid organs was observed in both animals. Histologically, suppurative to necrotizing inflammation with necrotizing vasculitis was present in the grossly affected organs of both animals. Yeast, pseudohyphae and branching hyphae were present within these lesions and C. albicans was isolated from lesional tissue of both animals. The primary site of Candida invasion was not determined in case 1, but the most likely portal of entry in case 2 was the gastric ulcers. Depletion of lymphoid tissue suggested a possible underlying iminune suppression in both animals. (C) 2008 Elsevier Ltd. All rights reserved.
