At global and local levels, we are observing an increasing range and rate of disease outbreaks that show evidence of jumping from animals to humans, and from food to humans. Zoonotic infections (i.e. Hendra, swine flu, anthrax) affect animal health and can be deadly to humans. The increasing rate of outbreaks of infectious diseases transferring from animals to humans (i.e. zoonotic diseases) necessitates detailed understanding of the education, research and practice of animal health and its connection to human health. These emerging microbial threats underline the need to exploring the evolutionary dynamics of zoonotic research across public health and animal health. This study investigates the collaboration network of different countries engaged in conducting zoonotic research. We explore the dynamics of this network from 1980 to 2012 based on large scientific data developed from Scopus. In our analyses, we compare several properties of the network including density, clustering coefficient, giant component and centrality measures over time. We also map the network over different time intervals using VOSviewer. We analyzed 5182 publication records. We found United States and United Kingdom as the most collaborative countries working with 110 and 74 other countries in 1048 and 599 cases, respectively. Our results show increasing close collaboration among scientists from the United States, several European countries including United Kingdom, Italy, France, Netherland, Switzerland, China and Australia with scientists from other parts of the world.
在全球和地方层面，我们观察到疾病暴发的范围和速度不断增加，这些暴发显示出从动物传播到人类以及从食物传播到人类的迹象。人畜共患感染（如亨德拉病毒、猪流感、炭疽）会影响动物健康，对人类可能致命。从动物传播到人类的传染病（即人畜共患病）暴发率不断上升，这就需要详细了解动物健康的教育、研究和实践及其与人类健康的联系。这些新出现的微生物威胁凸显了探索公共卫生和动物健康领域人畜共患病研究进化动态的必要性。本研究调查了从事人畜共患病研究的不同国家的合作网络。我们基于Scopus开发的大型科学数据，探索了1980年至2012年该网络的动态。在分析中，我们比较了该网络的几个属性，包括密度、聚类系数、巨型组件和中心性度量随时间的变化。我们还使用VOSviewer在不同时间间隔绘制该网络。我们分析了5182条出版物记录。我们发现美国和英国是合作最多的国家，分别在1048例和599例中与110个和74个其他国家合作。我们的结果表明，来自美国、包括英国、意大利、法国、荷兰、瑞士、中国和澳大利亚在内的几个欧洲国家的科学家与世界其他地区的科学家之间的合作日益密切。
