The genome DNA was extracted from the red blood cells or blood of the infected sheep and goats which include as isolates of ovine Babesia from these different geographic areas. The gene specific primers were devised according to the pubulished 18srRNA sequence at GenBank. The target DNA segment was amplified by polymerase chain reaction, the PCR product was ligated into PGEM-Teasy vector.
