Multilocus sequence typing uses nucleotide sequence from several genes to identify individual microbial pathogens. The data obtained for multilocus sequence typing can be used to recognize fungal species and to determine if the fungi are purely clonal, or if they also recombine. Genetic regions with more polymorphisms and microsatellites might be used to recognize populations within species and are well suited to Bayesian methods of assigning unknown individuals to populations of origin. Knowledge of species, populations and reproductive mode can help answer questions common to all emerging diseases: is the disease due to the recent spread of a pathogen, to the emergence of a virulent strain of an existing pathogen, or to a change in the environment that promotes disease?
多位点序列分型利用来自多个基因的核苷酸序列来识别个体微生物病原体。通过多位点序列分型获得的数据可用于识别真菌物种,并确定真菌是纯克隆的,还是也会发生重组。具有更多多态性和微卫星的遗传区域可用于识别物种内的种群,并且非常适合使用贝叶斯方法将未知个体分配到其起源种群。了解物种、种群和繁殖模式有助于回答所有新出现疾病共有的问题:该疾病是由于病原体最近的传播、现有病原体的毒力菌株的出现,还是由于促进疾病的环境变化引起的?
