From 2005 through 2008, we screened 650 Oregon spotted frogs (Rana pretiosa) from three populations in central Oregon, USA, for hemoparasites. A Hepatozoon sp., not previously reported in R. pretiosa, was found in one population of frogs, mostly as intracellular gamonts at a prevalence of 10.5% with parasitemias ranging from 0.02% to greater than 42% of erythrocytes within individual frogs. Intra-and extracellular merozoites were present, but rare. A potential vector, the mosquito Culex boharti, was common throughout the habitat of the population carrying Hepatozoon sp.
从2005年到2008年，我们对来自美国俄勒冈州中部三个种群的650只俄勒冈斑点蛙（Rana pretiosa）进行了血液寄生虫筛查。在一个蛙种群中发现了一种此前未在俄勒冈斑点蛙中报道过的肝簇虫属（Hepatozoon sp.），主要为细胞内配子体，感染率为10.5%，个体蛙的红细胞寄生虫血症范围从0.02%到超过42%。存在细胞内和细胞外裂殖子，但很罕见。一种潜在的传播媒介，博氏库蚊（Culex boharti），在携带肝簇虫属的种群栖息地中很常见。
