Endoscopic examinations are essential for diagnosis and treatment of strangles (S equi infection) in horses. However, even after disinfection, endoscopes may retain viable bacteria or bacterial DNA. Twitches are commonly used during endoscopic examinations and can thus also potentially transmit the organism to other horses.

内窥镜马链球菌马亚种残留污染的可能性和用于扼杀携带者诊断的抽搐。

内窥镜检查对于马的勒死（马链球菌感染）的诊断和治疗至关重要。然而，即使经过消毒，内窥镜也可能保留活细菌或细菌 DNA。抽搐通常在内窥镜检查中使用，因此也可能将有机体传播给其他马。
