Abstract

Antibodies against Rickettsia tsutsugamushi detected by the indirect fluorescent-antibody test (IFAT) were present in most rats trapped from a human focus of scrub typhus in the Philippines. Rickettsiae were isolated only from rats with positive IFATs. Naturally acquired antibodies persisted for at least 11 months, and antibodies resulting from experimental infections of rats persisted for at least 7 months. A common Philippine rodent, Rattus mindanensis, tolerated experimental infections with both local and standard Karp strains of R. tsutsugamushi, and such infections always produced a positive IFAT.

摘要

通过间接荧光抗体试验(IFAT)检测到,在菲律宾恙虫病人间疫源地捕获的大多数大鼠体内存在抗恙虫病立克次体抗体。立克次体仅从IFAT呈阳性的大鼠中分离出来。自然获得的抗体至少持续11个月,大鼠实验感染产生的抗体至少持续7个月。菲律宾常见啮齿动物明打威鼠能耐受当地和标准Karp株恙虫病立克次体的实验感染,且此类感染总能产生阳性IFAT结果。
