Identification and Detection of Prokaryotic Symbionts in the Ciliate Metopus from Anaerobic Granular Sludge.

abstract：:Giant viruses of 'Megaviridae' have the ability to widely disperse around the globe. We herein examined 'Megaviridae' communities in four distinct aquatic environments (coastal and offshore seawater, brackish water, and hot spring freshwater), which are distantly located from each other (between 74 and 1,765 km), usin...
