| Sumario: | OBJECTIVE: This study evaluated the effectiveness of five disinfectants: A33, 10% bleach, 1% bleach, SPOROX, and 3% H2O2, on military NATO and DECON litters. DESIGN: Suspensions oí Acinetobacter baumannii, Staphylococcus aureus, and spore-enhanced Bacillus subtilis, with five percent albumin, were inoculated onto litters and dried overnight. The litters were saturated with disinfectant solutions and sampled after 10 minutes. The Log|p reduction in the number of bacteria recovered was calculated. SETTING: 59* Medical Wing, 59* Clinical Research Division, Lackland AFB TX. MAIN OUTCOME MEASURES: A reduction of >3 Log, in the number of bacteria recovered from the test squares compared to the control squares was considered efiective disinfection. RESULTS: On the NATO litter 10% bleach and SPOROX were effective against vegetative cells. On the DECON litter A33,10% bleach, and SPOROX were effective against vegetative cells. After the 10 minute exposure none of the disinfectants evaluated were effective against spore-enhanced B. subtilis. CONCLUSION: When contaminated with vegetative cells military NATO and DECON litters can be effectively disinfected with a 10 minute exposure to some disinfectants. Further research is needed to find an effective disinfectant for spore contamination.
