Melophagus ovinus (sheep ked) is one of the most common ectoparasites that contributes to enormous economic losses in the productivity of sheep in many countries. The present study was conducted from January 2012 to July 2013 on M. ovinus collected from sheep at three sites in Ethiopia. Of the sheep studied, 65.7% (88/134) were infested with M. ovinus. The prevalence of M. ovinus was 76% (76/100), 47% (8/17) and 23.5% (4/17) at the Kimbibit, Chacha and Shano sites, respectively. An overall number of 229 M. ovinus specimens (138 females, 86 males and five pupae) and 554 M. ovinus specimens (272 females, 282 males) were collected from young and adult sheep, respectively. Bartonella DNA was detected in 89% (694/783) of M. ovinus using a quantitative Bartonella genus-specific PCR assay targeting the 16S/23S rRNA intergenic spacer region. The sequencing of the PCR products of fragments of the gltA and rpoB genes showed 99.6-100% and 100% homology, respectively, with B. melophagi. Statistically significant variation was not noted in the overall prevalence of Bartonella DNA between female and male M. ovinus. All of the sheep infested with M. ovinus 100% (88/88) harbored at least one M. ovinus specimen that contained Bartonella DNA. This study highlights that B. melophagi in M. ovinus from sheep in highlands in Ethiopia possibly has certain zoonotic importance.
