人和畜、禽的传染病中,有许多是以节肢动物为传播媒介的疾病。这类传染病的流行病学特点也必具有其媒介的生物学特点。因而,媒介生物学就成为研究这类疾病的流行病学规律、防治等的学科。自然疫源性疾病在自然疫源地中得以循环,如果没有媒介生物是不可能的。自然疫源地是一个特定的生态系统,是由病原生物、媒介生物、宿主生物及特定生境中其它生物与非生物因素相组合的生态系。1 媒介生物学的定义媒介生物学是以人畜疾病生物性传播的动
Among humans, livestock and poultry, many are arthropod-borne diseases. The epidemiological characteristics of such infectious diseases will also have the biological characteristics of their vectors. Therefore, the media biology has become the study of the epidemiology of such diseases, prevention and treatment of other disciplines. Natural foci of diseases are circulated in natural foci, and it is impossible without vector organisms. Natural foci are a specific ecosystem of ecosystems that are composed of pathogenic organisms, vector organisms, host organisms, and other living and abiotic factors in a particular habitat. 1 Definition of Media Biology Media biology is the biological transmission of diseases of humans and animals
