Perspectives for the treatment of brucellosis in the 21st century: the Ioannina recommendations.

Brucellosis is probably the commonest anthropozoonotic infection worldwide [1-3], but remains in various aspects an enigma in the 21st century [4]. Brucella melitensis remains the major cause of human disease worldwide, followed by B. abortus and B. suis, while rare but persisting cases of B. canis human infection and disease by novel Brucella pathogens of marine mammals have also emerged. The disease is re-emerging as a significant cause of travel-related disease [5] and represents an index of poor socioeconomic status (Figure 1). Its treatment is largely based even today on the principles applied half a century ago by pioneer researchers [6] and few modifications have been made in the following years, despite the emergence of new antibiotic classes and different therapeutic approaches [7]
