Biologic Causes of Occupational Dermatoses

Many virus skin infections may be of occupational origin: the most classical are orf, milkers’ node, herpes simplex, butchers’ warts, and hepatitis B. Bacterial skin infections of occupational origin are manifold: staphylococcal, streptococcal, erysipeloid, brucellosis, warty tuberculosis, BCG vaccination complications, anthrax, tularemia, and fish tank granuloma (mycobacteriosis). MRSA and CA-MRSA are an emerging problem of prime importance. A large variety of mycoses are related to occupational and/or recreational activities. They include most kinds of dermatophytoses, candidiasis, and subcutaneous and deep mycoses, the latter being predominantly imported skin diseases. Protothecosis is the only occupational skin disease due to an algae, Prototheca, mainly in tropical and subtropical countries
