目的：为了确定在加拿大北方流行地区之间的爆发之间的炭疽孢子污染的水平。方法和结果：细菌内生孢子提取标本通过浮选和选择性PLET培养基上培养。收集的588个环境标本，11（1.9%）含有可行的炭疽spores.Conclusions：高环境浓度的炭疽孢子在加拿大北方出现仅限于清道夫粪便和炭疽尸体的网站。埋葬和火葬似乎同样有效地从直接环境中去除炭疽孢子，虽然火葬可以通过重新燃烧含有未燃烧的动物hair.Significance和影响的研究：这项研究描述了一个有效的炭疽孢子检测系统的火葬场。它提供了第一个细菌学证据，证明哺乳动物清道夫可以在加拿大北方传播炭疽孢子，其结果可能与未来对未经处理的炭疽尸体地点的环境研究进行比较，以帮助改善政府的应对计划。
Aims: To determine the level of anthrax spore contamination in endemic regions of northern Canada between outbreaks.Methods and Results: Bacterial endospores were extracted from specimens via flotation and cultured on selective PLET medium. Of 588 environmental specimens collected, 11 (1.9%) contained viable anthrax spores.Conclusions: High environmental concentrations of anthrax spores in northern Canada appear limited to scavenger faeces and anthrax carcass sites. Burial and cremation appear equally effective at removing anthrax spores from the immediate environment, though cremation may be improved by re-burning cremation sites containing unburned animal hair.Significance and Impact of the Study: This study describes an effective anthrax spore detection system. It provides the first bacteriological evidence that mammalian scavengers can disseminate anthrax spores in northern Canada, and its results may be compared with future environmental studies of untreated anthrax carcass sites to help improve government response plans.
