Tracking airborne Legionella and Legionella pneumophila at a biological treatment plant

Blatny, Janet Martha; Reif, Bjørn Anders Pettersson; Skogan, Gunnar; Andreassen, Øyvind; Høiby, Ernst Arne; Ask, Eirik; Waagen, Viggo; Aanonsen, Dag; Aaberge, Ingeborg Aase S.; Caugant, Dominique A (2008)

Biological treatment plants are frequently used to degrade organic substances in wastewater from wood refinement processes. Aeration ponds in such plants provide an optimal growth environment for many microorganisms, ...

Evaluation of a highly discriminating multiplex multi-locus variable-number of tandem-repeats (MLVA) analysis for Vibrio cholerae

Olsen, Jaran Strand; Aarskaug, Tone; Skogan, Gunnar; Fykse, Else-Marie; Ellingsen, Anette Bauer; Blatny, Janet Martha (2009)

Vibrio cholerae is the etiological agent of cholera and may be used in bioterror actions due to the easiness of its dissemination, and the public fear for acquiring the cholera disease. A simple and highly discriminating ...

Assessment of the dispersion of Legionella-containing aerosols from a biological treatment plant

Blatny, Janet Martha; Tutkun, Murat; Fossum, Hannibal Eie; Skogan, Gunnar; Fykse, Else-Marie; Andreassen, Øyvind; Waagen, Viggo; Reif, Bjørn Anders Pettersson (2011)

Legionella was detected in aeration ponds (biological treatment plant) at Borregaard Ind. Ltd., Norway, and in air samples harvested directly above these ponds. Since 2005, three outbreaks of legionellosis occurred within ...

Temporal variability of the bioaerosol background at a subway station: Concentration level, size distribution, and diversity of airborne bacteria

Dybwad, Marius; Skogan, Gunnar; Blatny, Janet Martha (2014)

Naturally occurring bioaerosol environments may present a challenge to biological detection-identification-monitoring (BIODIM) systems aiming at rapid and reliable warning of bioterrorism incidents. One way to improve the ...

Comparative testing and evaluation of nine different air samplers: End-to-end sampling efficiencies as specific performance measurements for bioaerosol applications

Dybwad, Marius; Skogan, Gunnar; Blatny, Janet Martha (2014)

Accurate exposure assessments are needed to evaluate health hazards caused by airborne microorganisms and require air samplers that efficiently capture representative samples. This highlights the need for samplers with ...

Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system

Fykse, Else-Marie; Tjärnhage, Torbjörn; Humppi, Tarmo; Eggen, Vilde Sørvik; Ingebretsen, André; Skogan, Gunnar; Olofsson, Göran; Wästerby, Pär; Gradmark, Per-Åke; Larsson, Anders; Dybwad, Marius; Blatny, Janet Martha (2015)

The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ...
