American foulbrood disease (AFB) is an economically important, reportable bacterial infection of honey bees (Apis mellifera) caused by the spore-forming pathogen Paenibacillus larvae. Currently, there are no viable measures for treating P. larvae infected hives other than incineration. The objective of this study was to determine the activity of chlorine dioxide (ClO₂) gas against P. larvae spores. Sporicidal efficacy was dependent on treatment time and gas concentration with effective ClO₂ concentrations of 645 ng/ml for 30 min, 195 ng/ml for 1 h, 21 ng/ml for 2 h, or 16 ng/ml for 4 h. Treatment of surfaces with 230 ng/ml ClO₂ for one h or 195 ng/ml ClO₂ for 2 h completely inactivated P. larvae spores.

美国臭虫病 (AFB) 是一种经济上重要的、可报告的蜜蜂 ( Apis mellifera)细菌感染，由孢子形成病原体类芽孢杆菌幼虫引起。目前，除了焚化外，没有其他可行的措施来治疗感染P. 幼虫的荨麻疹。本研究的目的是确定二氧化氯 (ClO ₂ ) 气体对P. 幼虫孢子的活性。杀孢子效力取决于处理时间和气体浓度，有效的 ClO ₂浓度为 645 ng/ml 30 分钟、195 ng/ml 1 小时、21 ng/ml 2 小时或 16 ng/ml 4 小时。用 230 ng/ml ClO ₂处理表面一小时或 195 ng/ml ClO₂ 2 h 完全灭活P. 幼虫孢子。
