由兼性胞内细菌布鲁氏菌引起的布鲁氏菌病仍然是对动物和人类健康的全球性威胁。在这项研究中，我们旨在确定牛布鲁氏菌病的潜在危险因素，并评估印度希萨尔牲畜饲养者的知识、态度和做法。采用标准化问卷整理牛布鲁氏菌病潜在危险因素和畜主KAPs信息。共有127名牲畜饲养员受到影响。采用布鲁氏杆菌玫瑰孟加拉平板试验（RBPT）和间接酶联免疫吸附试验（iELISA）检测动物血清样本（n = 635）是否存在抗体。其中，78个（61.4%）畜群至少有一头血清呈阳性，302头（47.6%）牛血清呈阳性。单因素和多因素分析显示，集约化养殖场类型（OR = 4.6; 95% CI, 1.6-16.7；P= 0.009）、流产胎儿的卫生处理（OR = 0.3; 95% CI, 0.08-0.9；P= 0.04）和布鲁氏菌病血清阳性之间存在显著关联。96名（75.6%）受访者为18-50岁男性，82名（64.6%）拥有小型后院农场。只有51人（40.2%）知道布鲁氏菌病；其中54.9%（28/51）不能识别布鲁氏菌病的临床症状。6名（11.8%）参与者表示流产是最明显的临床症状，45.1%的参与者表示食用生牛奶与感染布鲁氏菌病的高风险相关。很大一部分受访者证实，他们经常食用（86.6%）动物的奶，并将其出售给他人（59.8%）。这些结果表明，牛布鲁氏菌病在哈里亚纳邦流行，那里可能经常出售受布鲁氏菌污染的牛奶。哈里亚纳邦的布鲁氏菌病控制工作应包括教育项目，以提高对该疾病的认识，以及在牛中控制该病和防止人畜共患病传播的方法。
Brucellosis caused by facultative intracellular bacteria,Brucella, remains a global threat to both animal and human health. In this study we aimed to identify potential risk factors of bovine brucellosis and to assess the knowledge, attitudes, and practices (KAPs) of livestock keepers in Hisar, India. A standardized questionnaire was used to collate information regarding potential risk factors of bovine brucellosis and livestock owners’ KAPs. A total of 127 livestock keepers were involved. Serum samples from their animals (n = 635) were tested for the presence of antibodies againstBrucellaby Rose Bengal Plate Test (RBPT) and indirect enzyme-linked immunosorbent assay (iELISA). Out of these, 78 (61.4%) of the herds had at least one seropositive animal, and 302 (47.6%) of the cattle were seropositive. Univariate and multivariate analysis revealed significant associations between intensive farm type (OR = 4.6; 95% CI, 1.6–16.7;P= 0.009), hygienic disposal of aborted fetuses (OR = 0.3; 95% CI, 0.08–0.9;P= 0.04) and herd seropositivity for brucellosis. The majority, 96 (75.6%) of the respondents, were males aged 18–50, and 82 (64.6%) owned a small-backyard farm. Only 51 (40.2%) of the participants knew about brucellosis; out of them, 54.9% (28/51) could not identify clinical signs of brucellosis. Six (11.8%) participants indicated abortion as the most noticeable clinical sign, and 45.1% indicated that consumption of raw milk is associated with high risk of contracting brucellosis. A large proportion of respondents confirmed that milk from their animals was regularly consumed (86.6%) and sold (59.8%) to other people. These results suggest that bovine brucellosis is endemic in Haryana, whereBrucella-contaminated milk is likely being regularly sold. Brucellosis control efforts in Haryana should include education programs to raise awareness of the disease and means to control it in cattle and to prevent zoonotic transmission.
