Dermatophilosis in a titi monkey (Callicebus moloch).

The occurrence of dermatophilosis in the titi monkey is reported. Lesions were principally in the epidermis of the skin and were characterized by parakeratosis, necrosis, abscess formation, acanthosis, and hyperkeratosis. The cause, Dermatophilus congolensis, was demonstrated as a gram-positive filamentous organism with both horizontal and vertical septums.
