¹ Washed A. baumannii cells were spotted on a smooth polystyrene surface and allowed to air dry. Dried cells were incubated at 19–23°C (mean 22°C), with a relative humidity of 25–61% (mean 46%). Results are from at least three separate experiments.

^† Average survival was approximately 90 days, based on the following results from four independent experiments: > 90 days, > 90 days, 44 days, 90 days.
