Real-time PCR and NASBA for rapid and sensitive detection of Vibrio cholerae in ballast water
(2012)
Transport of ballast water is one major factor in the transmission of aquatic organisms, including pathogenic bacteria. The IMO-guidelines of the Convention for the Control and Management of Ships’ Ballast Water and ...
Detection of Legionella pneumophila in a biological treatment plant by co-cultivatiobn with Acanthamoeba castellanii
(2014)
Legionella pneumophila was identified in the aeration ponds of a biological wastewater treatment plant at the pulp and paper industry Borregaard, Sarpsborg, Norway. After 3 outbreaks of Legionaires’ disease reported in ...
Complete genome sequences of six Legionella pneumophila isolates from two collocated outbreaks of legionnaires' disease in 2005 and 2008 in Sarpsborg/Fredrikstad, Norway
(2016)
Here, we report the complete genome sequences of Legionella pneumophila isolates from two collocated outbreaks of Legionnaires’ disease in 2005 and 2008 in Sarpsborg/Fredrikstad, Norway. One clinical and two environmental ...
Characterization of airborne bacteria at an underground subway station
(2012)
The reliable detection of airborne biological threat agents depends on several factors, including the performance criteria of the detector and its operational environment. One step in improving the detector's performance ...
Genotyping of B. licheniformis based on a novel multi-locus sequence typing (MLST) scheme
(2012)
Background
Bacillus licheniformis has for many years been used in the industrial production of enzymes, antibiotics and detergents. However, as a producer of dormant heat-resistant endospores B. licheniformis might ...
Assessment of the dispersion of Legionella-containing aerosols from a biological treatment plant
(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
(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
(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
(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 ...
L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences
(2014)
Background
L-alanine, acting through the GerA receptor, was recently found to be an efficient germinant in Bacillus licheniformis ATCC14580/DSM13.
Results
In this study, we show that several of 46 examined B. ...
