The Social Life of African Trypanosomes

The unicellular parasite Trypanosoma brucei shuttles between its definitive host, the tsetse fly, and various mammals including humans. In the fly digestive tract, T. brucei must first migrate to the ectoperitrophic space, establish a persistent infection of the midgut and then migrate to the salivary glands before being transmitted to a new mammalian host. In 2010, it was shown that insect stages of the parasite (procyclic forms) exhibit social motility (SoMo) when cultured on a semi-solid surface, and it was postulated that this behaviour might reflect a migration step in the tsetse fly. Now, almost 5 years after the initial report, several new publications shed some light on the biological function of SoMo and provide insights into the underlying signalling pathways.

Secret and power in social life

Secret and power constitute two fundamental instances of the social world. Secret takes care of the concealment of things and of social processes. Secret is also a power device. Power is the social capacity to do, create, not doing and stop from doing. Secret and power get mutual feedback. Power uses the secret to protect his potential, be it what may, to increment its operative strength. Secret uses the power to achieve its aims and proposals. Social sciences seem to ignore the huge explanatory capacity of these two interrelated concepts, and even more, their powerful intervention in societies.
