| establishing a new animal model for hepadnaviral infection: susceptibility of chinese marmota-species to woodchuck hepatitis virus infection. | hepatitis b virus infection (hbv) is a major medical problem in china. the lack of a suitable infection model in china is recognized as an obstacle for research on hbv in china. chinese marmota-species is phylogenetically closely related to marmota monax, thus, it might be suitable to serve as an animal model for hbv infection. therefore, we attempted to prove the claim about the existence of woodchuck hepatitis virus (whv)-like viruses in chinese marmota-species and to determine the susceptibil ... | 2010 | 21084496 |
| [spatial distribution of marmota baibacina and m. sibirica (marmota, sciuridae, rodentia) in a zone of sympatry in mongolian altai: bioacoustic analysis]. | the spatial distribution of two marmot species marmota baibacina and m. sibirica in a zone of coexistence was studied by using their alarm call as a diagnostic trait. it was found that m. baibacina prefers to inhabit bouldery screes, whereas m. sibirica inhabits all suitable biotopes. the difference in biotopic distribution of these species could be explained by m. sibirica forcing m. baibacina out of optimum habitats. cases of coexistence of both species in one family group sites were registere ... | 2016 | 20583623 |
| destruction of sound signal structure in a peripheral population (as exemplified by the gray marmot marmota baibacina). | the variability of the alarm call of the gray marmot (marmota baibacina) in the peripheral population in the valley of the arpa river (kyrgyzstan) is described. it was earlier reported that this population lived together with the red marmot (m. caudata). the authors did not find the red marmot there. two forms of aberrations were found in the edge population of the gray marmot: amplitude modulation and no pause between the components. the destruction of the signal structure that is typical of th ... | 2020 | 32894425 |
| marmots and yersinia pestis strains in two plague endemic areas of tien shan mountains. | the main purpose of this study was to clarify the role of gray marmots (marmota baibacina) in the long-term maintenance of highly virulent strains of yersinia pestis in two plague endemic foci of the tien shan mountains in kyrgyzstan. we present data from regular observations of populations of m. baibacina and small rodents cohabiting with marmots in the mountainous grasslands of the sari-dzhas (east of issyk-kul lake) and the upper-naryn (south of issyk-kul lake) natural foci. during 2012-2017, ... | 2019 | 31334249 |
| wildlife plague surveillance near the china-kazakhstan border: 2012-2015. | plague is a zoonotic disease caused by the bacterium yersinia pestis. this pathogen can be transmitted by fleas and has an enzootic cycle, circulating among small mammals, and occasionally epizootic cycles, infecting other species. in china, infected wild rodents are primarily reservoirs of y. pestis and are related to human infection (int. j. infect. dis., 33, 2015 and 67; bmc microbiol., 9, 2009 and 205). because shepherd dogs prey on and eat rodents (e.g. marmots and mice), they are valuable ... | 2017 | 28117561 |
| identification of different regions among strains of yersinia pestis by suppression subtractive hybridization. | yersinia pestis, the causative agent of bubonic and pneumonic plague, has been classified into four biovars: antiqua, mediaevalis, orientalis and microtus. although the entire genome sequences of three y. pestis strains, co92, kim and 91001, of biovar orientalis, mediaevalis and microtus, respectively, have been decoded, the genome sequence of the biovar antiqua strain is unknown. in an initial effort to find antiqua-specific sequences, suppression subtractive hybridization (ssh) was performed a ... | 2005 | 15993571 |

| current status of the sari-dzhas natural focus of plague, kyrgyzstan: epizootic activity and marmot population. | the sari-dzhas natural mountain focus of plague with an area of 5000 sq. km is located mainly in kyrgyzstan. this enzootic area belongs to a group of tien-shan mountain plague foci and crosses the boundaries of kazakhstan, kyrgyzstan, and china. after collapse of soviet union, this area was not investigated fully, thence we have estimated current status of hosts and vectors comparing to 1977 in the sari-dzhas focus. for period 1977-2014, the number of the gray marmot (marmota baibacina) as main ... | 2018 | 29989480 |
