Theileria equi isolate:Eagle Pass Genome sequencing and assembly

An isolate with infected red blood cell morphology similar to Theileria equi was found at the Eagle Pass, Texas quarantine station. The isolate does not test positive on the standard cELISA serological assay or by nested PCR, where the respective antigen or gene is ema1. Genome sequencing of the isolate was undertaken to determine why those tests may not be adequate in identifying horses infected with this isolate. Horses infected with Theileria equi are not permitted entry in to the United States. The Eagle Pass ema variant isolate may enter the United States undetected by current regulatory tests.

在德克萨斯州鹰口隔离站，发现了一株感染红细胞形态与泰勒虫属的 equi 类似的病原体。该病原体在标准 cELISA 血清学检测或通过嵌套 PCR 检测（其中分别针对抗原或基因 ema1）时均未呈阳性反应。对病原体的基因组测序工作已开展，以确定为何这些检测可能不足以识别感染此病原体的马匹。感染泰勒虫属 equi 的马匹不得进入美国。鹰口ema变异株的病原体可能未被发现地通过当前监管测试进入美国。
