| [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 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 ... | 2014 | 24738224 |
| [the formation of proventriculus block, alimentary activity and mortality of flea amphipsylla primaris primaris infected with yersinia pestis]. | the results of experiments held in 1982-1983 in tuva plague natural focus with flea amphipsylla primaris primaris (jordan et rothschild, 1915) from natural populations, whish were inflected and fed on specific host--flat-headed vole (alticola strelzovi), are analyzed. the initial infectivity of the insects in autumn was higher than in spring: 90 and 50 % respectively. accumulation of the agent in aggregated form in the organism of a. p. primaris, estimated by the quantity of fleas with <<lumps>> ... | 2006 | 16913294 |
