摘要
猪的蛔虫感染随宿主年龄及环境气象参数而变化。猪在2月龄时开始由粪便排出虫卵.4—6月龄时感染达到高峰,以后逐月降低。气象参数也有十分明显的影响,感染随逐月平均气温和降水量的变化而波动。有可能用数学模式来描述猪蛔虫感染与气象资料的关系。
The infestation status of Ascaris sm changed with the difference of host pigs' age and their environmental meteorological parameters.The Ascarides eggs begun being dispersed from 2- month-old pigs' faeces.The infestation reached peak when its hosts got 4—6 months old,then declined slowly.Meteorological parameters had a great influence too.Along with the changes of the month average temperature and rainfall,the infestation also fluctuated.It is possible to discribe the relationship between the infestation and some meteorological data using mathematical model.
