We explored the ploidy of six strains of Monocercomonoides using fluorescence in situ hybridization (FISH) with probes against the SufDSU gene known to be in a single copy in M. Its closest relatives still have small mitochondria, suggesting that it jettisoned the organelles fairly recently in evolutionary terms. Monocercomonoides is a genus of microaerophilic organisms living in the digestive tracts of animals. During host cell infection new parasites are formed through a budding process that parcels out nuclei and organelles into multiple daughters. There are plenty of nutrients present, but oxygen, which mitochondria need to make energy, is in short supply. ) It is the only eukaryote known to lack mitochondria.
