Abstract
Management practices to prevent or control outbreaks of Streptococcus equi subsp. equi often include consideration of environment survival, but limited objective data are available. This study involved evaluation of S. equi persistence following inoculation of wood, metal, and rubber surfaces in an outdoor environment. Survival was short, ranging from < 1 to 3 d. There was no effect of rain (P = 0.33) or surface type (P = 0.95), but there was an effect of sunlight (P = 0.002). Outdoor survival of S. equi is poor, and prolonged quarantine of outdoor areas, particularly areas exposed to the sun, is probably unnecessary.
