Livers of 4,023 white-tailed deer (Odocoileus virginianus) from 13 southeastern states were examined for flukes; 514 (12.8%) harbored Fascioloides magna. Other species of liver flukes were not found. Forty-two nidi of infection were found, encompassing 56 counties in 9 states. As many as 125 flukes were recovered from a single deer. Although F magna was widely distributed throughout southeastern United States, most enzootic areas were confined to the coastal plain physiographic province. Since deer serve as reservoirs for F magna infections in domestic livestock, it was concluded that every precaution should be exercised to prevent introduction of liver flukes into areas now free of this helminth.
对来自美国东南部13个州的4023头白尾鹿（弗吉尼亚鹿）的肝脏进行了吸虫检查；514头（12.8%）感染了巨片形吸虫。未发现其他种类的肝吸虫。发现了42个感染病灶，分布在9个州的56个县。一头鹿体内最多可检出125条吸虫。尽管巨片形吸虫在美国东南部广泛分布，但大多数地方流行区局限于沿海平原自然地理区域。由于鹿是家畜感染巨片形吸虫的储存宿主，因此得出结论，应采取一切预防措施，防止肝吸虫传入目前没有这种寄生虫的地区。
