实验动物不同对旋毛虫产幼虫数有影响,从大鼠小肠收集的成虫产虫数较长爪沙鼠和小鼠的明显为多;自雄性大鼠小肠所收集的成虫其产虫数较雌性大鼠的屈著为多;自大鼠小肠前半部所收集的成虫产虫数较小肠后半部者的著为多。感染大鼠的肌肉期幼虫用量对成虫的产虫数有影响,感染量越多,平均每条成虫产幼虫数越少。7日龄成虫其产虫数较5、9、11日龄的显著为多;在M—199或RPMT—1640完全培养液中成虫产虫数较在BME、MEM或Hank′s完全培养液中显著为多;37℃时培养的成虫其产虫数较25、30、35、40、42℃培养的显著为多。在20～160条/3ml培养液范围内成虫数不受培养密度的影响,在培养液中雌虫的产虫数不受雄虫存在与否的影响。
The number of adult worms collected from the rat small intestine was significantly higher than that of the gerbils and the gerbils of the gerbils; the adult worms collected from the small intestine of the male rats had more worms than the female ones Rats flexor as much; from the first half of the small intestine collected more adult worms than those in the latter half of the small intestine. The amount of muscle larvae in infected rats affected the number of adult worms. The more the infected animals, the less the average number of larvae per adult. The number of adult worms in 7-day-old adults was significantly higher than those in 5, 9 and 11 days. The number of adult worms in M-199 or RPMT-1640 complete medium was higher than that in BME, MEM or Hank’s complete medium Significantly higher than the number of adult worms cultured at 37 ℃ 25,30,35,40,42 ℃ significantly more. The number of adults in the range of 20 ~ 160 / 3ml culture medium was not affected by the culture density, and the number of females in the culture medium was not influenced by the presence or absence of male.
