The specific features of distribution of Neotrombicula (N) monticola Schluger et Davidov, 1967 on small mammals were studied in the Tien Shan montains (Kirghiz ridge). N. (N ) monticola was found to occur in all the places under study. Nine species of mammals (pigmy white-toothed shrew, dwarf hamster, tamarisk gerbil, Turkestan rat, long-tailed mouse, Tien(More)
The relationships that now occur between ixodid ticks and agents of salmonelloses have been analysed. The paper presents the material on the spontaneous infection of ixodids, experimental data on the preservation of salmonellae in these ticks, their interaction and a mechanism of the agents transmission to warmblooded animals during bloodsucking of the(More)
The paper considers the systematic points and nomenclature of the genus Pediculus lice. On the basis of some biological and environmental features, it provides evidence for species-specific independence of head and body lice. The morphological identity and reproductive insulating property allow one to subsume them under the heading of double species. In(More)
Histological studies have shown that in experimentally infected fleas (C. consimilis) Listeria are preserved in the alimentary canal. In infected individuals microbes occur along the whole intestine, from oesophagus to the rectum but most often they are recorded from the mid-gut and proventriculus. Listeria are able to penetrate into its muscular tissue and(More)
Histological studies of C. consimilis infected with S. typhimurium have shown that the microbes are preserves along the whole extent of the alimentary canal, expecially in the midgut and pyloric portion. Bacteria are concentrated in the gastral cavity; in addition, they were found to penetrate the alimentary epithelium cells and pyloric valve tissue. The(More)
The authors infected lambs with R. prowazeki and R. canada to ascertain their possible role in the natural infection of the animals. The lambs were infected subcutaneously with increasing doses; rickettsiemia was recorded with the aid of tests on guinea pigs and Ixodidae and Argasidae ticks fed on the lambs. Dynamics of antibody formation was ascertained in(More)
