1995 年3 月至1997 年11 月对鲁中南丘陵地区费县农田野鼠密度进行逐月观察,同时收集当地医院肾综合征出血热( H F R S) 和恙虫病发病资料。相关及回归分析表明当地农田优势鼠种黑线姬鼠与 H F R S及恙虫病发病率密切相关( 相关系数分别为r= 0562 , P< 0001 ,r= 0801 , P< 0005) ;大仓鼠仅与 H F R S 发病率相关(r = 0599 , P< 0001) ,与恙虫病发病率相关不显著。结果表明:黑线姬鼠是当地农田 H F R S和恙虫病的主要宿主动物,大仓鼠是次要宿主。
From March 1995 to November 1997, the densities of farmland in Feixian hilly area of central-southern Shandong Province were observed monthly. Meanwhile, the incidence of hemorrhagic fever with renal syndrome (HFRS) and scrub typhus in local hospitals was collected. Correlation and regression analysis showed that there was a close correlation between the prevalence of H F R S and scrub typhus in the dominant species of farmland (r = 0562, P <0001, r = 0801, P <0005). Hamsters were only associated with the incidence of H F R S (r = 0599, P <0001), but not with the incidence of scrub typhus. The results showed that Apodemus agrarius was the main host animal of H F R S and scrub typhus in local farmland, and the major hamster was the second host.
