The survival of bacteria in dust. II. The effect of atmospheric humidity on the survival of bacteria in dust

Abstract: Dust from scarlet-fever wards was exposed to a controlled range of atmospheric humidities by enclosure in metal boxes containing anhydrous calcium chloride and saturated solutions of potassium carbonate, sodium nitrite, potassium bromide and sodium sulphate.The death-rate of total organisms,Staphylococcus aureusandStreptococcus pyogenesin the dust was assessed by periodic sampling of series of twenty 10mg. portions. A positive correlation between atmospheric humidity and death-rate was observed for the three g… Show more

“…Temperature and relative humidity have been reported as two important factors related to the survival of bacteria in dust (24) and the number of airborne microorganisms (28). However, these variables cannot account for the differences in airborne bacterial concentrations shown in the present study because they were relatively homogeneous among all studied piggeries.…”

“…Survival of Y. pestis and other bacteria deposited on stainless steel coupons from airborne suspensions and held at several temperatures and humidity levels was studied by Wilkinson (30). Several factors that influence the ability of bacteria to survive desiccation include chemical and physical characteristics of the substrate material (26,29), air temperature and RH (12)(13)(14)30), the organism's growth phase (11), and cell surface characteristics (17,30). Survival data for desiccation of Y. pestis are conflicting due to variations in experimental design, substrate, and environmental conditions (17).…”

“…In particular, the employment of an infection control nurse often improves the situation by drawing attention to and implementing infection control measures [10]. S. aureus survival within the hospital environment is well documented [11][12][13], and some epidemic strains can remain viable for longer on cotton lint than other strains [14]. The mechanisms of enhanced survival are poorly understood, but resistance to desiccation [13,15], adherence [16], and the ability to survive on human skin [15][16][17] have been implicated.…”
