2.1.3. Babesia sp. CA-type

Four severe to fatal human cases with Babesia sp. CA-type have been reported in splenectomized patients from California ( Persing et al., 1995). This species is morphologically indistinguishable from B. duncani , but can be distinguished by genetic sequencing of multiple targets. No vector or reservoir has been identified, but genetically similar organisms have been detected in mule deer, bighorn sheep, and a captive fallow deer ( Dama dama ) from California. However, sequence analysis of the 18S rRNA gene and internal transcribed spacer (ITS)-2 region has revealed limited nucleotide differences between the Babesia spp. from cervids and Babesia sp. CA-type from humans ( Conrad et al., 2006).
