The kind of parasites a horse acquires depends upon its environment. Because patterns of transmission vary greatly with climate and management, no one worming program has universal applications. This article discusses epidemiology and control of equine parasites in the southern United States, where climates vary from warm temperate to subtropical and from humid in the southeast to arid in the southwest.
马感染的寄生虫种类取决于其生活环境。由于传播模式因气候和管理方式的不同而有很大差异，因此没有一种驱虫方案能普遍适用。本文讨论了美国南部马寄生虫的流行病学及防治，该地区气候从暖温带到亚热带不等，东南部湿润，西南部干旱。
