The daily cyclical variation in Leucocytozoon smithi gametocyte numbers in the peripheral blood of domestic turkeys was shifted 12-hr. by exposure of hosts to a reversed photoperiod. Peak parasitemia coincided with the midpoint of the artificial light period (0100 hr.), while low parasitemia occurred between 1300 hr. and 1700 hr. Disruption of strict gametocyte periodicity was suggested by results of birds exposed to light varying in intensity from 700 lux during the day to 161 lux at night although marked fluctuations in gametocyte numbers occurred.
通过使宿主暴露于反向光周期，家火鸡外周血中史密斯住白细胞原虫配子体数量的每日周期性变化提前了12小时。寄生虫血症高峰与人工光照期的中点（01:00）相吻合，而低寄生虫血症则发生在13:00至17:00之间。尽管配子体数量出现明显波动，但暴露于白天强度为700勒克斯、夜间强度为161勒克斯的变化光照下的鸟类实验结果表明，严格的配子体周期性受到了干扰。
