本文报道在南非持续研究有关盐浓度对传播血吸虫病的影响,作者观察了梅氏血吸虫、埃及血吸虫和曼氏血吸虫南非株的虫卵孵化力与毛蚴的寿命和感染力。实验材料、条件和试验盐浓度:均与Donnelly等(1983)所报道的一样。三种血吸虫虫卵孵化力和毛蚴寿命试验所用盐浓度为1.75、3.5、5.25、7.0、8.75、10.5、14.0、17.5、27.0、35.0‰。毛蚴感染力试验所用的盐浓度为1.0、1.75、2.5、3.5、4.5、5.25‰。
This paper reports on the effects of salt concentration on the transmission of schistosomiasis in South Africa. The authors observed the hatching power and the lifespan and infectivity of the eggs of Schistosoma mansoni, Schistosoma mansoni and S. mansoni in South Africa. Experimental Materials, Conditions, and Test Salt Concentration: Both are as reported by Donnelly et al. (1983). Three kinds of Schistosoma japonicum egg hatching power and life expectancy of malariae salt concentration used 1.75,3.5,5.25,7.0,8.75,10.5,14.0,17.5,27.0,35.0 ‰. The concentration of salt used in the test for infection of cercariae was 1.0, 1.75, 2.5, 3.5, 4.5, and 5.25 ‰.
