Ovipleistophora (Microsporidia) is a globally distributed genus of obligate parasites that infect fish, Crustacea, and trematodes. We report on two additional crayfish hosts, Procambarus pictus (Simms Creek, Florida) and Procambarus fallax (Santa Fe River, Florida), that exhibited signs of high-intensity microsporidian infection in the musculature. Sequence data (SSU) for the isolates were 99.79% and 99.97% similar to Ovipleistophora diplostomuri parasitizing Procambarus bivittatus. Additional screening of regional fish species (Lepomis macrochirus) revealed additional microsporidian diversity (Potaspora) but did not include Ovipleistophora. Detecting Clade V isolates in multiple host groups provides further evidence for trophic transmission among Clade V microsporidia.
寡衣小孢子虫（Microsporidia）是一种广泛分布的专性寄生虫属，感染鱼类、甲壳类动物和吸虫。我们报告了另外两种小龙虾宿主，即佛罗里达州西蒙斯溪的彩石蟹（Procambarus pictus）和佛罗里达州圣达菲河的蓝蟹（Procambarus fallax），它们的肌肉组织表现出高强度微孢子虫感染的迹象。分离株的 SSU 序列数据与感染 Procambarus bivittatus 的寡衣小孢子虫 Diplostomuri 相似，相似度为 99.79%和 99.97%。对区域鱼类物种（蓝鳃太阳鱼）的进一步筛选显示出更多的微孢子虫多样性（Potaspora），但不包括寡衣小孢子虫。在多个宿主群体中检测到 Clade V 分离株进一步证明了 Clade V 微孢子虫之间的营养传播。
