肝孢子虫在1993年4月至2005年10月期间，在两种日本野猫中发现了感染，它们是Iriomote野猫(Felis Iriomtensis)和对马豹猫(Felis Bengalensis Euptilura)。患病率分别为56.7%(17/30)和14.3%(6/42)。受影响最严重的器官是心脏；所有受感染的动物心脏中都有有机体。寄生形式为裂殖体，并可观察到不同发育阶段。裂殖体和裂殖子的大小分别为22.3+/-3.1×15.3+/-2.2微米和6.1+/-0.6×2.3+/-0.2微米。未观察到针对寄生虫的炎症反应。电子显微镜下，微生物位于寄主细胞的寄生液泡中，成熟的裂殖体由大量的裂殖子组成。这是首次报道日本猫科动物的肝孢子虫病。
Hepatozoon sp. infections were detected in two species of Japanese wild cat, Iriomote wild cat (Felis iriomotensis) and Tsushima leopard cat (Felis bengalensis euptilura), between April 1993 and October 2005. The prevalence was 56.7% (17/30) and 14.3% (6/42), respectively. The most affected organ was the heart; all infected animals had organisms in their hearts. The parasitizing form was schizont and various developmental stages were observed. The size of schizont and merozoite was 22.3 +/- 3.1 x 15.3 +/- 2.2 mu m and 6.1 +/- 0.6 x 2.3 +/- 0.2 mu m, respectively. Few inflammatory reactions against the parasites were observed. Electron microscopically, organisms were located in parasitophorous vacuoles of unidentified host cells, and mature schizonts consisted of numerous merozoites. This is the first report of hepatozoonosis in Japanese felids.
