The phylogenetic position of Ovavesicula popilliae (Microsporidia) and its relationship to Antonospora and Paranosema based on small subunit rDNA analysis.
Comparative small subunit rDNA sequence analyses, indicate that Ovavesicula popilliae, a microsporidian parasite of the Japanese beetle, Popillia japonica, represents a distant sister group to Paranosema and Antonospora. These three genera represent a second major group (the Nosema/Vairimorpha clade representing the first) of Microsopridia which infect terrestrial insects, suggesting independent origins for both groups. Phylogenetic analyses of Ovavesicula and other Microsporidia having a multi-sporous sporogony reveal that this condition is found in several unrelated taxa implying either that multi-sporous sporogony is the ancestral condition for Microsporidia or that it has multiple origins.
