Abstract：
:The genus Anaplasma currently comprises 6 bacterial species mostly pathogenic to animals and/or human, including the zoonotic species Anaplasma phagocytophilum, the causative agent of tick-borne fever (TBF) of ruminants, and of granulocytic anaplasmosis of horses, dogs and human. Recently, novel potentially non-pathogenic strains related to A. phagocytophilum have been identified in Japan, China, and Tunisia. This paper reports the identification, molecular typing, and evolutionary history of novel Anaplasma strains (A. phagocytophilum-like 1 and 2), related to but distinct from A. phagocytophilum in Mediterranean area of Europe and Africa. PCR-RFLP and phylogenetic analyses based on 16S rRNA provided evidence for the circulation of A. phagocytophilum-like 1 strains in Europe. Phylogeny based on groEL gene showed the inclusion of Sardinian and Tunisian A. phagocytophilum-like 1 strains in a unique clade distinct from, but related to that of Japanese strains. Results suggest that genetic diversity within the genus Anaplasma is much greater than expected and provide information useful for the development of specific and effective diagnostic and prophylactic tools.
