Henneguya doori Guilford, 1963 (Myxosporea) has an annual development cycle on the gills of adult Perca flavescens. The cycle involves a period of summer invasion, fall development of plasmodia and initiation of sporogenesis, winter completion of sporogenesis, and spring release of spores. An experiment revealed that rising water temperature in spring promotes cyst rupture and loss. The development of cysts is synchronized within individual fish and among members of the host population. As such, the parasite spends 8-9 mo in perch tissues to produce a single annual generation that culminates in a 4-6 wk period of spore dispersal. The parasite does not appear to be pathogenic. The observed cycle of H. doori repeated itself over 4 yr of sampling in Vinegar Lake, Nova Scotia.
杜氏亨内粘体虫（Henneguya doori Guilford，1963年）（粘孢子虫纲）在成年黄鲈（Perca flavescens）的鳃上有一个年度发育周期。这个周期包括夏季入侵期、秋季的多核体发育和孢子形成的起始、冬季孢子形成的完成以及春季孢子的释放。一项实验表明，春季水温上升会促使包囊破裂和消失。包囊的发育在个体鱼体内以及宿主种群成员之间是同步的。因此，这种寄生虫在鲈鱼组织中度过8至9个月以产生一个年度世代，最终在4至6周的时间内进行孢子传播。这种寄生虫似乎没有致病性。在新斯科舍省醋湖进行的4年采样中，观察到的杜氏亨内粘体虫的周期不断重复。
