The involvement of some flea species in the epizootic process in the Gorno-Altai natural plague focus: spatial and temporary characteristics

The relative number of plague pathogen strains isolated from some flea species in different Gorno-Altai natural plague foci substantially varies; this indicator also varies with time. These patterns are due to the difference in the structure of multispecies communities of ectoparasites in these area...

Summary:The relative number of plague pathogen strains isolated from some flea species in different Gorno-Altai natural plague foci substantially varies; this indicator also varies with time. These patterns are due to the difference in the structure of multispecies communities of ectoparasites in these areas and their long-term transformation. As of now, the three species Paradoxopsyllus scorodumovi, Ctenophyllus hirticrus, and Amphalius runatus are widely involved in pathogen transmission in all three foci. These ectoparasites should be referred to as main plague vectors. In each focus, they are joined by other flea species, such as Rhadinopsylla dahurica and Amphipsylla primaris in the Ulandryk focus, Frontopsylla hetera, R. dahurica, Paradoxopsyllus kalabukhovi, and Paramonopsyllus scalodae in the Tarkhatin focus, and P. scalonae and P. kalabukhovi in the Kurai focus, which should be classified as an additional vector.
