  abstract = {{C}assava bacterial blight ({CBB}), caused by {X}anthomonas phaseoli pv. manihotis ({X}pm), poses a significant threat to cassava production in {B}urkina {F}aso. {P}rior to this study, the geographical distribution, incidence and origin of {CBB} introductions were poorly understood. {I}n this investigation, we assessed the incidence of {CBB} in major cassava-cropping regions and analysed the genetic diversity of 344 {X}pm strains collected from 19 fields between 2015 and 2016, using a multilocus variable number of tandem repeat analysis ({MLVA}) scheme targeting 14 microsatellite markers. {O}ur results reveal the presence of {CBB} in three out of four cropping regions, with incidences ranging from 0% to 100% at locality and variety scale. {B}urkina {F}aso's {X}pm strains exhibited high genetic diversity at multiple levels, including country scale ({H}e = 0.6), cropping region (0.43 to 0.57), locality (0.25 to 0.50) and field (0.25 to 0.52). {P}airwise comparisons among populations from different cropping areas indicated a strong genetic differentiation. {T}he categorical minimum spanning tree reveals that the {C}ascades region has the higher diversity indices and consequently could be the origin site of dispersion of {X}pm in the other cropping regions of cassava. {H}uman activities play a major role in the dissemination of {X}pm through cassava cuttings. {T}he importance of the sanitary state of cuttings must be emphasized in order to avoid {CBB} and ensure good cassava production.},
