Cyclic AMP Regulates Social Behavior in African Trypanosomes
UNLABELLED The protozoan parasite Trypanosoma brucei engages in surface-induced social behavior, termed social motility, characterized by single cells assembling into multicellular groups that coordinate their movements in response to extracellular signals. Social motility requires sensing and responding to extracellular signals, but the underlying mechanisms are unknown. Here we report that T....
متن کاملSocial Motility in African Trypanosomes
African trypanosomes are devastating human and animal pathogens that cause significant human mortality and limit economic development in sub-Saharan Africa. Studies of trypanosome biology generally consider these protozoan parasites as individual cells in suspension cultures or in animal models of infection. Here we report that the procyclic form of the African trypanosome Trypanosoma brucei en...
متن کاملMandrills use olfaction to socially avoid parasitized conspecifics
The evolutionary transition from a solitary to a social lifestyle entails an elevated parasite cost because the social proximity associated with group living favors parasite transmission. Despite this cost, sociality is widespread in a large range of taxonomic groups. In this context, hosts would be expected to have evolved behavioral mechanisms to reduce the risk of parasite infection. Few emp...
متن کاملAntennal Drumming, Trophallaxis, and Colony Development in the Social Wasp Polistes fuscatus (Hymenoptera: Vespidae)
Parental care is widespread among both vertebrates and invertebrates. In some species, the parents provide the young only with protection from predators and ⁄or parasites, but in most others the adults provide nutrients for their immature offspring. The latter context has led to the evolution of social behavior in a few groups, notably in some of the mammals and in the social Hymenoptera (Alexa...
