Abstract

Babesiosis and Anaplasmosis are diseases associated with economic losses; ticks and blood-sucking flies are important zoonotic vectors and reservoirs. This study aimed to investigate the presence of anti-Babesia spp. and anti-Anaplasma marginale antibodies using enzyme-linked immunosorbent assay (ELISA), in ruminants at the Catimbau National Park. Blood samples were collected from 119 sheep, 119 goats, and 47 cattle. Rhipicephalus microplus ticks were collected from cattle. ELISA showed seropositivity of 34% (16/47), 20.3% (24/119), and 16% (19/119) for anti-Babesia bovis; 34% (16/47), 15.2% (18/119), and 9% (7/119) for anti-Babesia bigemina; and 34% (16/47), 35.6% (42/119), and 17% (20/119) for anti-A. marginale antibodies in cattle, goats, and sheep, respectively. The information collected using an epidemiological questionnaire showed that mostly are breed in a semi-intensive system, with access to Caatinga vegetation. The circulation of B. bovis, B. bigemina, and A. marginale was confirmed. Thus, based on the prevalence, this suggests this is an enzootic instability area and is prone to outbreaks.

巴西东北部半干旱地区卡廷博国家公园反刍动物中巴贝斯虫和阿纳普拉原虫的出现。

巴贝西亚原虫病（Babesiosis）和无形体病（Anaplasmosis）是与经济损失相关的疾病；蜱虫和吸血蝇是重要的人畜共患病媒和储库。本研究旨在使用酶联免疫吸附试验（ELISA）调查卡廷鲍国家公园反刍动物中是否存在抗巴贝西亚原虫和抗边疟原虫抗体。采集了 119 只绵羊、119 只山羊和 47 头牛的血液样本。从牛身上采集了 Rhipicephalus microplus 蜱虫。酶联免疫吸附试验（ELISA）显示，牛、山羊和绵羊的抗牛巴贝斯虫抗体血清阳性率分别为 34%（16/47）、20.3%（24/119）和 16%（19/119）；抗大肠巴贝斯虫抗体血清阳性率分别为 34%（16/47）、15.2%（18/119）和 9%（7/119）；抗边虫抗体血清阳性率分别为 34%（16/47）、35.6%（42/119）和 17%（20/119）。通过流行病学调查问卷收集到的信息显示，大部分牛羊都是在半集约化系统中饲养，可以接触到卡廷加植被。牛包虫病、大肠包虫病和边缘包虫病的传播已得到证实。因此，根据流行情况，这表明这里是一个疫情不稳定的地区，很容易爆发疫情。
