Scrotal palpation, microscopical examination of semen smears and the application of bacteriological techniques, revealed the incidence of Actinobacillus seminis and Brucella ovis infection of rams in the central and southern districts of the Orange Free State to be 2,9% and 4,3%, respectively. More Dorper than Merino rams were affected. Although clinically detectable epididymitis was found in 5,9% of rams examined, infection with A. seminis and B. ovis, as measured by the presence of neutrophils in semen and positive semen cultures, could only be demonstrated in a small minority of affected cases. These organisms were found more regularly in clinically negative rams excreting neutrophils in their semen. Possible reasons for the high incidence of sheep brucellosis in rams in the particular area as well as the higher incidence of infection in Dorper rams are discussed.
阴囊触诊、精液涂片显微镜检查以及细菌学技术的应用显示，奥兰治自由邦中部和南部地区公羊的精液放线杆菌和绵羊布鲁氏菌感染率分别为2.9%和4.3%。受影响的杜泊公羊比美利奴公羊更多。尽管在检查的公羊中有5.9%临床上可检测到附睾炎，但通过精液中嗜中性粒细胞的存在和精液培养阳性来衡量，只有一小部分受影响的病例能检测到精液放线杆菌和绵羊布鲁氏菌感染。在精液中排出嗜中性粒细胞的临床阴性公羊中更经常发现这些病原体。讨论了该特定地区公羊绵羊布鲁氏菌病发病率高以及杜泊公羊感染率更高的可能原因。
