恙虫病病毒と所謂「リケッチア」細胞に関する形態学的研究 第1編 恙虫病病毒感染ハツカネズミにおける所謂「リケッチア」細胞の本態に関する研究

In mice infected with Rickettsia tsutsugamushi and suffering from the disease, there appears the peritoneal exudate containing the so-called "rickettsial cells" in which many riekettsiae are observed. The essence of the so-called "rickettsial cells" remains, however, as yet unexplained. In the present series of experiments, the author tried the cytological classification of the "rickettsial cells" in detail as well as the interrelation between these cells and rickettsiae. As a result of these experiments, it became clear that the so-called "rickettsial cells" consisted of both of the serosal cells in which rickettsiae were multiplying actively and the histiocytes which gormandized the multiplied rickettsiae; this gives a new definition of the so-called "rickettsial cells."
