Extremophiles and their application to veterinary medicine

: Extremophiles are organisms that can grow and thrive in harsh conditions, e.g., extremes of temperature, pH, salinity, radiation, pressure and oxygen tension. Thermophilic, halophilic and radiation-resistant organisms are all microbes, some of which are able to withstand multiple extremes. Psychrophiles, or cold-loving organisms, include not only microbes, but fish that live in polar waters and animals that can withstand freezing. Extremophiles are structurally adapted at a molecular level to withstand these conditions. Thermophiles have particularly stable proteins and cell membranes, psychrophiles have flexible cellular proteins and membranes and/or antifreeze proteins, salt-resistant halophiles contain compatible solutes or high concentrations of inorganic ions, and acidophiles and alkaliphiles are able to pump ions to keep their internal pH close to neutrality. Their interest to veterinary medicine resides in their capacity to be pathogenic, and as sources of enzymes and other molecules for diagnostic and pharmaceutical purposes. In particular, thermostable DNA polymerases are a mainstay of PCR-based diagnostics.     

DNA疫苗免疫机理及其在动物医学中的应用

疫苗在人和家畜疾病防治方面起着巨大的作用，它主要是通过激发机体的免疫系统来达到疾病防治的目的。目前传统的疫苗主要有灭活疫苗、减毒疫苗及基因工程多肽苗。随着现代免疫学和分子生物学技术的发展，在上个世纪90年代初，一种新型的疫苗DNA疫苗诞生了。
