Summary A naplasma species are obligate intracellular rickettsial pathogens transmitted by ticks with an impact on human and animal health. A naplasma ovis infects sheep and goats in many regions of the world, and it can be diagnosed by different methods like Giemsa staining, PCR or competitive ELISA . In this study, a PCR based on the gene coding for major surface protein 4 ( MSP ‐4) was used to examine field samples collected from sheep in different countries. Altogether, 1161 blood samples from Turkey ( n = 830), I raq ( n = 195), S udan ( n = 96) and P ortugal ( n = 40) were examined, of which 31.4%, 66.6% 41.6% and 82.5%, respectively, were positive. This indicates high prevalence of A . ovis in the countries under investigation, and it can be assumed that the situation in other areas of the world might be similar. Thus, A . ovis should be considered as an important constraint of livestock production, and further efforts are needed to better understand the epidemiology and to implement suitable control measures.
