During 1986, fecal specimens were collected 1 or more times from each of 164 horse foals (158 Thoroughbred and 6 mixed light horse type), ranging in age from 0 to 252 days, on 13 farms in central Kentucky. To detect natural infection with Eimeria leuckarti, feces were examined for oocysts. Oocysts were found in 67 (41%) of the foals on 11 (85%) of the farms. The earliest age at which oocysts were first detected was 15 days (1 foal); the latest age was 123 days (1 foal). The mean age for the first appearance of oocysts in the feces of the 67 foals positive for E leuckarti was approximately 70 days. Age of the oldest foal that passed oocysts was 185 days. The longest oocyst shedding period was about 4 months, although oocyst-positive feces usually were found only sporadically during this period.
1986年期间，在肯塔基州中部的13个农场，从164匹年龄在0至252天的马驹（158匹纯种马和6匹混血轻型马）中，每匹马驹采集粪便标本1次或多次。为检测马艾美球虫的自然感染情况，对粪便进行了卵囊检查。在11个（85%）农场的67匹（41%）马驹粪便中发现了卵囊。首次检测到卵囊的最小年龄为15天（1匹马驹）；最大年龄为123天（1匹马驹）。67匹马艾美球虫阳性马驹粪便中首次出现卵囊的平均年龄约为70天。排出卵囊的最老的马驹年龄为185天。最长的卵囊排出期约为4个月，不过在此期间通常只是偶尔发现有卵囊阳性的粪便。
