Treatment of wild rats from a known scrub typhus focus in the Philippines with cyclophosphamide did not significantly enhance the isolation rate of Rickettsia tsutsugamushi using mouse inoculation techniques. Similarly, cyclophosphamide treatment of mice inoculated with organs of wild rats did not increase the recovery of rickettsiae, and isolation of rickettsiae was about equal from biopsies obtained before and after immunosuppression of wild rats.
用环磷酰胺处理来自菲律宾已知恙虫病疫源地的野生大鼠,使用小鼠接种技术并未显著提高恙虫病立克次体的分离率。同样,用环磷酰胺处理接种野生大鼠器官的小鼠,也没有增加立克次体的回收率,并且从野生大鼠免疫抑制前后获取的活检组织中立克次体的分离情况大致相同。
