Campylobacter spp. are a leading cause of sheep abortions worldwide; Campylobacter fetus ssp. fetus has historically been the major culprit. Increasingly, however, C. jejuni has been isolated from cases of sheep abortion, and it has now replaced C. fetus ssp. fetus as the predominant cause of Campylobacter-related ovine abortion in the United States. Emergence of a single tetracycline resistant clone (clone SA) has been implicated as the primary reason for this shift. Virulence factors for clone SA have still not been completely elucidated, and it is not known how this bacterium reaches the uterine and placental tissue from the ...
