Colonization of a bovine burn wound by Trichosporon beigelii

Abstract

Summary. Trichosporon beigelii, an emerging opportunistically zoopathogenic fungus, was demonstrated both by culture and by direct microscopy in the chronic, ulcerated burn wound of a 3‐month‐old Jersey cow. The fungus was probably limited to the cutaneous tissues since it was not isolated from blood, urine or faeces, nor from nasal, eye or ear swabs. It is suggested that etiological significance of Tr. beigelii should be considered when the organism is isolated from animals that are immunosuppressed either due to some underlying disease or due to the prolonged use of cytotoxic drugs. Zusammenfassung. Trichosporon beigelii, ein opportunistischer tierpathogener Pilz zunehmender Bedeutung, wurde direktmikroskopisch und kulturell in einer chronischen ulzerierten Wunde einer drei Monate alten Jersey‐Kuh nachgewiesen. Der Pilz blieb offensichtlich auf die kutanen Gewebe beschränkt, denn er konnte weder aus Blut, Urin und Faezes noch aus der Nase, dem Ohr und vom Auge isoliert werden. Die ätiologische Bedeutung von Tr. beigelii sollte immer dann in Betracht gezogen werden, wenn der Pilz aus Tieren isoliert wird, die wegen einer Grundkrankheit oder wegen Langzeitmedikation mit zytotoxischen Verbindungen immunsupprimiert sind.,

Contribution of Prof. Dr. Mahendra Pal in Cutaneous Mycoses

“…Prof. Pal has the credit to develop sunflower seed medium (Pal medium), APRM (Anubha, Pratibha, Raj, Mahendra) medium, PHOL (Pal Hasegawa, Ono, Lee) stain, and Narayan stain for the studies of fungi that are implicated in various clinical disorders of humans and animals [1,12,[14][15][16]. He is credited to elucidate for the first time the etiologic significance of Tricochosporon beigelii in burn wound of cattle [17], Trichophyton verrucosum in dermatitis of barking deer [6], Exserohium rostratum in equine dermatitis [18], Aphanoascus fulvescens in canine dermatitis [19], Candida tropicalis in dermatitis of rabbit [20], and Aspergillus terreus in buffaloes [9]. Prof. Pal has also described dermatophytosis in monkey, hog deer, bear, lion, barking deer for the first time in India [1].…”
