A 31-months study was conducted to elucidate the prevalence of brucellosis in nomadic pastoralists and their goats in two provinces of the eastern Algerian high plateaus. Five hundred eight human and 4955 animal sera were screened with the Rose Bengal plate test and the complement fixation test for confirmation. Uterine fluids from aborting goats were subjected to microbiological analyses to determine the biovars responsible for abortions. The overall seroprevalence was 0.98% among animals and 15.84% among herds. A significant correlation was recorded between occurrence of brucellosis and herd size (r = 0.4046, P < 0.0001) as well as age (χ(2) = 5.809, P = 0.0159) and sex of animals (χ(2) = 20.09, P < 0.0001); 89.65% of human cases were related to positive herds and the infection rate was higher in men (7.6%) than in women (6%) and children (0.92%). Brucella melitensis biovar 3 was the only aetiology of brucellosis-associated abortion in goats of the studied region.
开展了一项为期31个月的研究，以阐明阿尔及利亚东部高原两个省份游牧牧民及其山羊中布鲁氏菌病的流行情况。采用玫瑰红平板试验和补体结合试验对508份人类血清和4955份动物血清进行筛查以作确认。对流产山羊的子宫液进行微生物分析，以确定导致流产的生物变种。动物的总体血清阳性率为0.98%，畜群的总体血清阳性率为15.84%。布鲁氏菌病的发生与畜群规模（r = 0.4046，P < 0.0001）、动物年龄（χ(2) = 5.809，P = 0.0159）及性别（χ(2) = 20.09，P < 0.0001）之间存在显著相关性；89.65%的人类病例与血清阳性畜群有关，男性的感染率（7.6%）高于女性（6%）和儿童（0.92%）。马尔他布鲁氏菌生物变种3是研究地区山羊布鲁氏菌病相关流产的唯一病因。
