Caption
This is a microscopic representation of a tsetse fly, the biological vector of the Trypanosoma parasite. During the feeding process, the parasite is transmitted by the fly from infected to uninfected vertebrate hosts. After uptake of the trypanosomes from an infected human, the parasite reproduces itself within the tsetse fly, representing the sexual phase of the trypanosome life cycle. After several replication cycles, the parasite is again transferred to vertebrates.
