With the rapid socioeconomic development, increasingly frequent personnel exchanges, and blossoming of tourism, a large number of people enter the natural plague foci for tourism and sightseeing, which greatly increases the chance of exposure to plague-infected animals and vector insects for floating populations. Once plague is transmitted to humans, it will be introduced into the urban areas within a very short period of time by modern means of transport such as airplanes, trains, and automobiles, which increases the risk of prompt transmission of plague. Qinghai province has the natural plague focus of Marmota himalayana which have spread across the province. Based on the tourism development and potential risk of plague in Qinghai province, it will assure and accelerate the healthy development of tourism to take corresponding prevention and control measures according to the practical situation of tourism.

Objective To better use achieves of hosts and vectors of Marmota himalayana plague natural foci in Qinghai province, and to provide convenient, fast, scientific and accurate information for prediction and prevention of plague epidemic in the future. Methods The mammals collected were made into taxidermy in general, part of the mammals were made into ecological modeling specimens. Fleas, mites, and ticks were made into mounting slides. All the specimens were registered for their collection information, and the specimen achieves were set up and preserved. Results A total of 30 420 specimens from the M. himalayana plague natural foci in Qinghai province were preserved in the Qinghai Endemic Control Institute, including mammals belonging to 6 orders, 26 families, 45 genera and 110 species. There are 174 species of 6 families, 43 genera of fleas, 12 species of ticks, 68 species from 16 families, 18 genera of sucking lice, as well as 123 species from 12 families, 35 genera of mites. Conclusion We collected, produced and preserved a large number of hosts and vectors related to plague epidemic in this epidemic area, which provided a scientific basis for the basic work of plague foci investigation and animal plague surveillance.

Objective To observe the growth of Yersinia pestis on different kinds of culture media and screen for high quality culture media. Methods Make 5 kinds of culture media (Hiss Agar, Nutrient Agar, Sulfite Agar base, Hemolysis Agar Base, and Agar Hottinger nutrient)according to the instructions and pour into plates. Inoculating 0.1 ml Y. pestis suspensions on the prepared plate, calculating viable bacteria after 48-hour cultivation under 28℃ and observing the growth of Y. pestis on different culture media. Results There is no significant difference among Hiss Agar, Nutrient Agar and Sulfite Agar base. And the difference between Hemolysis Agar Base and Agar Hottinger nutrient was not significant either. The first three culture media and the following two culture media were also not significantly different. Hemolysis Agar Base and Agar Hottinger nutrient were superior to other culture media Hiss Agar, Nutrient Agar, Sulfite Agar base on growth of Y. pestis. Conclusion All the five culture media can be used for culture of Y. pestis, but Hemolysis Agar Base and Agar Hottinger nutrient were superior to the others.

Objective To investigate the epidemic of plague in the past 10 years along the Qinghai-Tibet Railway, and to provide a scientific basis for the prevention and control of plague in future. Methods The monitoring results and clinical data for the human plague epidemic along the Qinghai-Tibet Railway from 2003 to 2013 were collected and analyzed using descriptive epidemiological methods. Results The emergence of plague in both animals and humans mainly occurred in the areas of Geermu (Tanggulashan Township), Tianjun, and Wulan in the Qinghai section of the Qinghai-Tibet Railway from 2003 to 2013. Sixty-nine strains of Yersinia pestis and 86 sera with positive F1 antibody were detected in these areas; 7 cases of human plague occurred, and 3 cases died. Conclusion Serious epidemic of plague remains in the Qinghai section of the Qinghai-Tibet Railway. Frequent occurrence of plague between animals and sporadic human plague epidemic are mainly related to illegal marmot hunting in these key areas.
