The gender of vertebrate hosts may affect the outcome of parasitic infections. An experimental murine infection with Angiostrongylus costaricensis was followed with determinations of body weight, fecal larval elimination, number and length of adult worms, number of macroscopic intestinal lesions, and mortality. Groups of male and female Swiss mice were infected with 10 3(rd)-stage A. costaricensis larvae per animal. The results indicate there are no significant differences related to gender of the host, except for higher length of worms developed in male mice.
脊椎动物宿主的性别可能会影响寄生虫感染的结果。对感染哥斯达黎加管圆线虫的实验小鼠进行了跟踪观察，测定了体重、粪便中幼虫排出情况、成虫的数量和长度、肉眼可见的肠道损伤数量以及死亡率。将雄性和雌性瑞士小鼠分组，每只动物感染10条第三期哥斯达黎加管圆线虫幼虫。结果表明，除了雄性小鼠体内发育的蠕虫长度更长外，与宿主性别无关的差异并不显著。
