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. 4. Instead of mitochondria, Monocercomonoids use a sulfur modulator system for energy production that can adapt to their habitat (because Monocercomonoids are endoparasites). The team’s phylogenetic analysis, published today (May 12) in Current Biology, suggests that Monocercomonoides —which belong to the Oxymonadida group of protozoa and live in low-oxygen environments — did have mitochondria at one point, but eventually lost the organelles.
