Sera from 2,630 apparently normal adult camels (Camelus dromedarius) raised in central Saudi Arabia (Riyadh and Al-Kharj cities) were examined serologically by the Rose Bengal and standard United States of America Brucella plate agglutination tests. The overall seroprevalence of brucellosis in the restricted populations of tested camels was 8%. The seroprevalence of brucellosis among camels raised in small numbers in the backyards of 24 houses in Riyadh and those intensively raised on one large camel farm near Al-Kharj were 4.3% and 8.6% respectively. Fresh milk samples from 100 brucellosis seropositive camels from Riyadh and Al-Kharj were cultured on Brucella-selective media. Brucella melitensis biovars 1 and 2 were isolated and identified from 26 camels. Epidemiologically, brucellosis in camels in central Saudi Arabia appeared to be connected with B. melitensis infection of sheep and goats, and also represents a serious public health risk.
对来自沙特阿拉伯中部（利雅得和哈吉尔市）饲养的2630头外观正常的成年单峰骆驼（骆驼属单峰驼）的血清，采用玫瑰红试验和美国标准布鲁氏菌平板凝集试验进行血清学检测。在受检测骆驼的特定群体中，布鲁氏菌病的总体血清阳性率为8%。在利雅得24户人家后院少量饲养的骆驼以及哈吉尔附近一个大型骆驼养殖场集中饲养的骆驼中，布鲁氏菌病的血清阳性率分别为4.3%和8.6%。从利雅得和哈吉尔的100头布鲁氏菌病血清阳性骆驼采集的新鲜牛奶样本，在布鲁氏菌选择性培养基上进行培养。从26头骆驼中分离并鉴定出了马尔他布鲁氏菌生物变种1和2。从流行病学角度看，沙特阿拉伯中部骆驼的布鲁氏菌病似乎与绵羊和山羊的马尔他布鲁氏菌感染有关，并且也构成严重的公共卫生风险。
