largely unknown. Given the existence of Bartonella spp. in every mammal group examined to date, the diversity of the genus is probably much greater than has been observed among the strains examined to date. In Greece, serologic evidence of human infection with B. henselae and B. quintana (8), has been found and a case of B. quintana endocarditis has been established (unpub. data). The public health relevance of Bartonella infections in small mammals in Greece compared with other countries remains to be defined.
