A total of 1 076 sera from breeding goats were randomly collected from 24 different farms and tested with CHEKIT®-ELISA (IDEXX Laboratories B.V., 1 119 NE Schiphol-Rijk, Nederland) for antibodies against Chlamydophila abortus. The farms were divided into two categories of twelve farms each,based on their previous history of observed abortions over the previous 12 months: those with low (< 5%) levels of abortion and those with high (≥ 5%) levels of abortion. The farmers were also interviewed on their level of awareness about chlamydophilosis, its zoonotic importance and vaccination measures against the disease. The study detected overall seroprevalence levels of 25% for the farms and 8% for the individual animals (at 95% confidence). A total of six out of twentyfour farms (25%) had at least one positive breeding animal. Only five out of the twenty-four (20.8%)farmers interviewed were aware of chlamydophilosis and its zoonotic dangers. None of the 24 farmers interviewed practised any vaccination against chlamydophilosis. There was a significantly higher number of seropositive animals from farms with high levels of abortion, compared to those animals from farms with low levels of abortion (p = 0.0001). This study underscores the need for a higher level of farmer awareness and training on chlamydophilosis and its zoonotic dangers.
从24个不同农场随机采集了1076份种羊血清，并用CHEKIT®-ELISA（荷兰艾迪威公司，史基浦-里耶克东北1119号，荷兰）检测抗流产嗜衣原体抗体。根据过去12个月观察到的流产史，这些农场被分为两类，每类12个农场：流产率低（<5%）的农场和流产率高（≥5%）的农场。还就农民对嗜衣原体病的了解程度、其人畜共患病重要性以及针对该病的疫苗接种措施进行了访谈。该研究检测到农场总体血清阳性率为25%，个体动物血清阳性率为8%（95%置信度）。24个农场中有6个（25%）至少有一只种羊血清呈阳性。接受访谈的24位农民中只有5位（20.8%）知道嗜衣原体病及其人畜共患病危险。与流产率低的农场的动物相比，流产率高的农场血清阳性动物数量显著更多（p = 0.0001）。这项研究强调需要提高农民对嗜衣原体病及其人畜共患病危险的认识和培训水平。
