  1. Occurrence of airborne bacteria and pathogen indicators during land application of sewage sludge.

    Article - En anglais

    Glass impingers (AGI-30) were used at a commercial sludge application site to determine the levels of airborne bacteria and pathogen indicators.

    Even though heterotrophic bacteria averaged 105 CFU/m3, none of the sites showed the presence of Salmonella spp. or indicators such as fecal coliforms or coliphages.

    Indicators such as H2S producers and pathogenic clostridia were present in locations having significant physical agitation of the sludge material.

    PCR-based ribotyping using the 16S-23S interspacer region is a promising method to identify the genetic relatedness and origins of airborne clostridia.
