| streptococcus himalayensis sp. nov., isolated from the respiratory tract of marmota himalayana. | five strains of gram-positive-staining, catalase-negative, coccus-shaped, chain-forming organisms isolated separately from the respiratory tracts of five marmota himalayana animals in the qinghai-tibet plateau of china were subjected to phenotypic and molecular taxonomic analyses. comparative analysis of the 16s rrna gene indicated that these singular organisms represent a new member of the genus streptococcus, being phylogenetically closest to streptococcus marmotae dsm 101995t (98.4 % similari ... | 2017 | 27902227 |
| streptococcusmarmotae sp. nov., isolated from the respiratory tract of marmota himalayana. | five strains of a gram-stain-positive, catalase-negative, α-haemolytic, coccus-shaped chain-forming organism were isolated separately from the lower respiratory tracts of five animals of marmota himalayana in the endemic area of plague, the qinghai-tibet plateau, china. based on their morphological characteristics, biochemical features and molecular phylogenetic studies, the strains were placed as representing a new member of the genus streptococcus. comparative 16s rrna gene sequence studies in ... | 2016 | 27473166 |
| escherichia marmotae sp. nov., isolated from faeces of marmota himalayana. | the taxonomic position of a group of seven closely related lactose-negative enterobacterial strains, which were isolated from fresh faecal samples of marmota himalayana collected from the qinghai-tibetan plateau, china, was determined by using a polyphasic approach. cells were gram-reaction-negative, non-sporulating, non-motile, short rods (0.5-1 × 1-2.5 μm). by 16s rrna gene sequences, the representative strain, ht073016(t), showed highest similarity values with escherichia fergusonii atcc 3546 ... | 2015 | 25851592 |
| [food habits and hunting patterns of tibetan brown bear during warm seasons in kekexili region on qinghai-tibetan plateau]. | tibetan brown bear (ursus arctos pruinosus) is an endemic subspecies of brown bear on the qinghai-tibetan plateau. we once reported a preliminary study on the summer food habit of tibetan brown bear from july to august, 2005 in the kekexili (hoh xil).. however, the hunting modes of the tibetan brawn bear have not been reported. from july to august, 2009, we collected additional data on food habits and hunting patterns of tibetan brown bear in the kekexili region. we found tibetan brown bears are ... | 2010 | 21174359 |
| [study on the genotyping and microevolution of yersinia pestis in the qinghai-tibet plateau]. | to study the distribution of genomovars and microevolution of yersinia pestis in the qinghai-tibet plateau. | 2006 | 16981338 |
| mapping risk of plague in qinghai-tibetan plateau, china. | qinghai-tibetan plateau of china is known to be the plague endemic region where marmot (marmota himalayana) is the primary host. human plague cases are relatively low incidence but high mortality, which presents unique surveillance and public health challenges, because early detection through surveillance may not always be feasible and infrequent clinical cases may be misdiagnosed. | 2014 | 25011940 |
| niche modeling predictions of the potential distribution of marmota himalayana, the host animal of plague in yushu county of qinghai. | after the earthquake on 14, april 2010 at yushu in china, a plague epidemic hosted by himalayan marmot (marmota himalayana) became a major public health concern during the reconstruction period. a rapid assessment of the distribution of himalayan marmot in the area was urgent. the aims of this study were to analyze the relationship between environmental factors and the distribution of burrow systems of the marmot and to predict the distribution of marmots. | 2016 | 26912171 |
| diverse novel astroviruses identified in wild himalayan marmots. | with advances in viral surveillance and next-generation sequencing, highly diverse novel astroviruses (astvs) and different animal hosts had been discovered in recent years. however, the existence of astvs in marmots had yet to be shown. here, we identified two highly divergent strains of astvs (tentatively named qinghai himalayanmarmot astvs, hhmastv1 and hhmastv2), by viral metagenomic analysis in liver tissues isolated from wild marmota himalayana in china. overall, 12 of 99 (12.1 %) m. himal ... | 2017 | 28100306 |
| genetic evidence for subspecies differentiation of the himalayan marmot, marmota himalayana, in the qinghai-tibet plateau. | the primary host of plague in the qinghai-tibet plateau (qtp), china, is marmota himalayana, which plays an essential role in the maintenance, transmission, and prevalence of plague. to achieve a more clear insight into the differentiation of m. himalayana, complete cytochrome b (cyt b) gene and 11 microsatellite loci were analyzed for a total of 423 individuals from 43 localities in the northeast of the qtp. phylogenetic analyses with maximum likelihood and bayesian inference methods showed tha ... | 2017 | 28809943 |
| insights into the evolution of pathogenicity of escherichia coli from genomic analysis of intestinal e. coli of marmota himalayana in qinghai-tibet plateau of china. | escherichia coli is both of a widespread harmless gut commensal and a versatile pathogen of humans. domestic animals are a well-known reservoir for pathogenic e. coli. however, studies of e. coli populations from wild animals that have been separated from human activities had been very limited. here we obtained 580 isolates from intestinal contents of 116 wild marmot marmota himalayana from qinghai-tibet plateau, china, with five isolates per animal. we selected 125 (hereinafter referred to as s ... | 2016 | 27924811 |
| streptococcus halotolerans sp. nov. isolated from the respiratory tract of marmota himalayana in qinghai-tibet plateau of china. | two gramstaining-positive, catalase-negative, α-hemolytic, coccus-shaped organisms were isolated separately from the respiratory tracts of two marmota himalayana animals from the qinghai-tibet plateau, pr china. morphological, biological, biochemical, and molecular genetic studies were performed on these two isolates (hts9t and hts12). their biochemical characteristics, such as acid production from different sugars and enzymatic activities, indicated that they represented a member of the genus s ... | 2016 | 27469933 |
