Protozoa of the Hexamita meleagridis species were isolated for the first time in this country. The infection was observed in turkeys at the age of 2 to 5 weeks. The parasite was shown to have oval body measuring 8.16 Mm (length) and 3.55 Mm (width) two nuclei, and eight symmetrically attached filaments. The latter were shown to serve Hexamita organisms which exhibit exclusive motility. The identification of the parasite was made through the study of smears (of the content of small intestines with catarrhal inflammation) under the microscope in a dark field or with staining after Giemsa. Demonstration proved possible only with the use of either freshly killed turkeys that were clinically affected with the disease or dead turkeys that were still warm. At the second hour following death no Hexamita were found.
该国首次分离出火鸡六鞭原虫。在2至5周龄的火鸡中观察到感染情况。该寄生虫呈椭圆形，长8.16毫米，宽3.55毫米，有两个细胞核和八条对称附着的鞭毛。后者被证明是六鞭原虫的运动器官，六鞭原虫具有独特的运动方式。通过在暗视野显微镜下研究涂片（来自患有卡他性炎症的小肠内容物）或吉姆萨染色后进行寄生虫鉴定。只有使用临床感染该病的新鲜宰杀火鸡或仍温热的死火鸡才能观察到。死亡后两小时未发现六鞭原虫。
