Sporicidal effect of alcohol-NaCl solution spray against spore-forming bacteria, C. difficile (a) Sporicidal activity of (i) IPA-NaCl solution spray, (ii) EtOH-NaCl solution spray (mean ± SD, n = 3). The y-axis represents spore forming unit (SFU/mL), and the x-axis represents time (min). 0 min represents the initial C. difficuile spore suspension in DI water. (b) Negative-stain transmission electron microscopy (TEM) images after 30 min of incubation at RT following exposure to alcohol-NaCl spray.
