Description
Summary:[Display omitted] •We detected a high prevalence of Nosema ceranae in native Bombus atratus and Bombus bellicous from Uruguay.•Bombus atratus females presented higher prevalence than males.•Intensity of infection was lower in males in both bumblebee species. Nosema ceranae is one of the most prevalent pathogens in Apis mellifera and has recently been found in multiple host species including several species of bumblebees. Prevalence and infection intensity of N. ceranae was determined in two species of native bumblebees from Uruguay. Nosema ceranae was the only microsporidia identified and mean prevalence was 72% in Bombus atratus and 63% in Bombus bellicosus, values much higher than those reported elsewhere. The presence of this pathogen in bumblebees may be threatening not only for bumblebee populations, but also to the rest of the native pollinator community and to honeybees.
