Ovipleistophora diplostomuri (Microsporidia) is an obligate parasite of fish and trematodes in the US. In April 2019, an individual crayfish, Procambarus bivittatus (Escambia River, Florida), with a high-intensity microsporidian infection was delivered to the Emerging Pathogens Institute. Histological analysis determined that infection was restricted to the muscle tissue. Molecular diagnostics (PCR) provided 952 bp of the parasite SSU (18S) sequence. The isolate was 99.16% similar to O. diplostomuri identified from blue gill and their trematode parasites in Washington, USA. This discovery increases our understanding of Microsporidia within aquatic trophic networks, supporting the theory that the Ovipleistophora share complex relationships with vertebrates, invertebrates and helminth parasites.
双殖吸虫微孢子虫（微孢子虫）是美国鱼类和吸虫的专性寄生虫。2019年4月，一只感染高强度微孢子虫的小龙虾（双带原螯虾，佛罗里达州埃斯坎比亚河）被送到了新兴病原体研究所。组织学分析确定感染仅限于肌肉组织。分子诊断（PCR）提供了952 bp的寄生虫小亚基（18S）序列。该分离株与从美国华盛顿州蓝鳃太阳鱼及其吸虫寄生虫中鉴定出的双殖吸虫微孢子虫相似度为99.16%。这一发现增进了我们对水生营养网络中微孢子虫的了解，支持了双殖吸虫微孢子虫与脊椎动物、无脊椎动物和蠕虫寄生虫存在复杂关系的理论。
