Tropical dermatology: bacterial tropical diseases.

UNLABELLED: Bacterial infections are common in tropical parts of the world and can include those species also seen regularly in temperate climates. Many tropical bacterial infections, however, are rarely diagnosed in temperate parts of the world and include bartonellosis, tropical ulcer, tropical pyomyositis, granuloma inguinale, lymphogranuloma venereum, yaws, pinta, melioidosis, and glanders. Some tropical bacterial diseases, eg, plague and anthrax, are associated with high mortality rates and are of potential use in bioterrorism. Some tropical bacterial diseases are closely associated with specific activities such as hunting (ie, tularemia) or eating raw seafood (Vibrio vulnificus infection). The bacterial diseases having the most severe medical impact in the tropics are those caused by members of the Mycobacterium genus. Millions of persons throughout the world suffer from tuberculosis and leprosy; Buruli ulcers are common causes of morbidity in many tropical countries. Because of the increasing frequency of travel to tropical parts of the world for tourism and work as well as the increasing number of immigrants and adoptees from these areas, it is imperative that physicians practicing in temperate climates be able to recognize the signs and symptoms of tropical bacterial diseases, carry out the proper diagnostic tests, and initiate appropriate therapy and prevention.
