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 ... -
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 ... -
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 ... -
Genetic distribution of 295 Bacillus cereus group members based on adk-screening in combination with MLST (Multilocus Sequence Typing) used for validating a primer targeting a chromosomal locus in B. anthracis
Olsen, Jaran S.; Skogan, Gunnar; Fykse, Else Marie; Rawlinson, Elizabeth L. A.; Tomaso, Herbert; Granum, Per Einar; Blatny, Janet (2007)The genetic distribution of 295 Bacillus cereus group members has been investigated by using a modified Multilocus Sequence Typing method (MLST). By comparing the nucleic acid sequence of the adk gene fragment, isolates ... -
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 ... -
Performance evaluation of high-volume electret filter air samplers in aerosol microbiome research
Gohli, Jostein; Dybwad, Marius; Skogan, Gunnar (2020)Background Reliable identification and quantification of bioaerosols is fundamental in aerosol microbiome research, highlighting the importance of using sampling equipment with well-defined performance characteristics. ... -
Standoff detection of biological agents using laser induced fluorescence - a comparison of 294 nm and 355 nm excitation wavelengths
Farsund, Øystein; Rustad, Gunnar; Skogan, Gunnar (2012)Standoff detection measuring the fluorescence spectra of seven different biological agents excited by 294 nm as well as 355 nm wavelength laser pulses has been undertaken. The biological warfare agent simulants were released ... -
The subway microbiome: Seasonal dynamics and direct comparison of air and surface bacterial communities
Gohli, Jostein; Bøifot, Kari Oline; Moen, Line Victoria; Pastuszek, Paulina; Skogan, Gunnar; Udekwu, Klas I; Dybwad, Marius (2019-12-19)Background Mass transit environments, such as subways, are uniquely important for transmission of microbes among humans and built environments, and for their ability to spread pathogens and impact large numbers of people. ... -
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 ... -
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, ...
