General Information: Sodalis glossinidius is known exclusively in endosymbiosis with tsetse flies. It is maternally transmitted, and is one of the few bacterial endosymbionts of insects that can be cultured successfully in vitro. Genome data reveals a high proportion of pseudogenes in this species, many of which were, in their functional state, involved in defense or transport of carbohydrates and inorganic ions. This suggests a degenerative adaptation to the immunity and restricted nutritional status of the host.
