({V}.) guyanensis from {F}rench {G}uiana based on 12 microsatellite loci. {T}he results revealed important homozygosity and very modest linkage disequilibrium, which is in agreement with a high level of sexual recombination and substantial endogamy. {T}hese results also revealed a significant isolation by distance with relatively small neighbourhoods and hence substantial viscosity of {L}eishmania populations in {F}rench {G}uiana. {T}hese results are of epidemiological relevance and suggest a major role for natural hosts and/or vectors in parasite strain diffusion across the country as compared to human hosts.}, keywords = {clonality ; endogamy ; {L}eishmania {V}iannia guyanensis ; microsatellites ; population genetics ; substructuring}, booktitle = {}, journal = {{M}olecular {E}cology}, volume = {20}, numero = {15}, pages = {3116--3127}, ISSN = {0962-1083}, year = {2011}, DOI = {10.1111/j.1365-294{X}.2011.05162.x}, URL = {https://www.documentation.ird.fr/hor/fdi:010053710}, }
