Detection of Ehrlichia risticii, the agent of Potomac Horse Fever, in freshwater stream snails (Pleuroceridae: Juga spp.) from northern California
Article Abstract:
Research was conducted to examine the detection of ehrlichia DNA in freshwater operculate snails, Pleuroceridae: Juga spp., found in the stream water in a pasture in northern California in which potomac horse fever (PHF) is enzootic. The DNA sequencing of a suite of genes indicated that the source organism may be closely related to Ehrlichia risticii, the causative agent of PHF. Results suggest that operculate snails of the genus Juga may have an important role in the life cycle of E. risticii in northern California.

Novel genetic variants of Anaplasma phagocytophilum, Anaplasma bovis, Anaplasma centrale, and a novel Ehrlichia sp. in wild deer and ticks on two major islands in Japan
Article Abstract:
Blood samples were obtained from wild deer on two major islands Hokkaido and Honshu and tested with a view to determining whether and what species of Ehrlichia and Anaplasma naturally infect deer in Japan. DNA sequence analysis revealed that enzootic cycles of Ehrlichia and Anaplasma speciesdistinct from those found in the US or Europe are established in wild deer and ticks in Japan.

Equine and canine Anaplasma phagocytophilum strains isolated on the Island of Sardinia (Italy) are phylogenetically related to pathogenic strains from the United States
Article Abstract:
An investigation on the presence of Anaplasma phagocytophilum, a tick-transmitted zoonotic pathogen in Sardinia, Italy using a molecular approach was conducted. Phylogenetic analysis revealed that Sardinian strains are genetically distinct from the two lineage previously described in Europe and were closely related to strains isolated in different areas of the US.
