Cochliomyia hominivorax GBS

The New World screwworm, Cochliomyia hominivorax, is a major parasite of livestock and other warm-blooded animals in the western hemisphere. It historically ranged from the southern US, through Central America, and much of South America and the Caribbean. It has since been eradicated from the US, and through Central America down to the Panama -Colombian border where a permanent quarantine zone is maintained. Currently eradicated areas benefit from an estimated $1.3 billion annually. However, outbreaks such as occurred in Florida in 2016, do occur in eradicated areas and a database for determining the source of outbreaks would be beneficial. This study aimed to characterize the geographic population structure from 11 locations using the high-resolution molecular marker, SNPs which were obtained using genotyping by sequencing.

新大陆螺虫，学名Cochliomyia hominivorax，是西半球家畜及其他温血动物的重要寄生虫。该虫种历史上分布范围从美国南部延伸至中美洲，覆盖了大部分南美洲和加勒比海地区。如今，该虫种已从美国境内以及中美洲地区直至巴拿马-哥伦比亚边境被根除，并在此处维持了一个永久性检疫区。目前，已根除区域每年可受益于约13亿美元的收益。然而，如2016年佛罗里达州发生的疫情爆发等事件表明，疫情爆发在已根除区域内仍有可能发生，建立一个用于确定疫情爆发源头的数据库将大有裨益。本研究旨在利用高分辨率分子标记，即通过测序进行基因分型获得的SNPs，对来自11个地点的地理种群结构进行表征。
