DBS collected from 20 human subjects with known M. perstans infection and living in the Okola health district (Cameroon) were shipped to Montpellier to be used as references for phylogenetic analyses [3]. DNA extraction from DBS was performed using the NucliSENS® kit (bioMérieux, Craponne, France) according to the manufacturer’s instructions, as previously described [21]. DNA was eluted in 60 µl buffer. The PCR reactions on the M. perstans mf-positive human blood samples were carried on once all other samples had been tested.
