Equine protozoal myeloencephalitis is a commonly diagnosed neurological disease of horses in North America and is caused by infection with Sarcocystis neurona or Neospora hughesi. The aim of this study was to compare prevalence factors among horses seropositive or seronegative to N. hughesi and/or S. neurona. A total of 3123 submissions were included in the study, with horses originating from 49 States. Thirty-eight animals from 21 States tested seropositive for N. hughesi only, 840 horses from 40 States were seropositive for S. neurona only, 25 horses from 14 States were seropositive for both protozoa, and 2220 horses from 49 States tested seronegative for both parasites. Significant associations were found between geographical location (State), month of submission, breed and serological status.
马属动物原虫性脑脊髓炎是北美地区常见的马匹神经系统疾病,由感染肉孢子虫或休斯新孢子虫引起。本研究的目的是比较对休斯新孢子虫和/或肉孢子虫血清呈阳性或血清呈阴性的马匹之间的流行因素。该研究共纳入了3123份样本,马匹来自49个州。来自21个州的38只动物仅对休斯新孢子虫血清呈阳性,来自40个州的840匹马仅对肉孢子虫血清呈阳性,来自14个州的25匹马对两种原虫血清均呈阳性,来自49个州的2220匹马对两种寄生虫血清均呈阴性。研究发现地理位置(州)、送检月份、品种和血清学状态之间存在显著关联。
