We identify bacteria types on collected dust samples in Dakar Senegal, a region that experiences frequent Saharan dust events. We use classical techniques to identify bacteria types from dust samples. Seventy‐seven bacteria types are identified from samples collected by spatula and the QuickTake® 30 air sampling pump. The dominant groups in the first batch of 51 bacteria (collected via deposition) are Micrococcus (33.33%), Bacillus (13.73%), Kytococcus (11.76%), Pseudomonas (9.80%), and Burkholderia (7.84%) and dominants in the second batch of 26 bacteria (collected with aerosol sampling vacuum pump): Pseudomonas (38.61%), Burkholderia (26.92%), Micrococcus (11.54%), and Brucella spp (7.69%). These bacteria are found in earlier studies from desert sources and can potentially cause respiratory diseases to exposed populations. Future work will use molecular methods is necessary to search for additional pathogens, including viruses on dust aerosols.

西非塞内加尔达喀尔尘埃事件中气溶胶上细菌的表征。

我们在塞内加尔达喀尔（该地区经常发生撒哈拉沙尘事件）的收集到的尘埃样本上确定细菌类型。我们使用经典技术从灰尘样品中识别细菌类型。从锅铲和QuickTake®30空气采样泵收集的样品中鉴定出77种细菌类型。在第一批51种细菌（通过沉积收集）中的优势群体是微球菌（33.33％），芽孢杆菌（13.73％），动球菌（11.76％），假单胞菌（9.80％）和伯克霍尔德菌（7.84％），以及第二批26种细菌（通过气溶胶采样真空泵收集）：假单胞菌（38.61％），伯克霍尔德菌（26.92％），微球菌（11.54％）和布鲁氏菌（7.69％）。这些细菌是在较早的研究中从沙漠来源中发现的，并可能导致暴露人群的呼吸道疾病。未来的工作将需要使用分子方法来寻找其他病原体，包括粉尘气溶胶上的病毒。
