Popis: | The microbial content of dust collected from intake and exhaust air filters in six Norwegian nurseries was determined using 16S rRNA pyrosequencing and plate count analyses. The concentration of endotoxins was also estimated. About 96% of the sequences were classified as Actinobacteria, Proteobacteria, Firmicutes, Bacteroidetes and Cyanobacteria. At the genus level, about 30% of sequences from the exhaust filter were classified as bacteria of probable human origin, such as Streptococcus and Corynebacterium species. These were close to absent in intake dust samples ( |
