Laboratory Diagnostics of Botulism
Miia Lindström,Hannu Korkeala +1 more
TL;DR: The laboratory diagnostics of botulism should aim at increasing the understanding of the epidemiology and prevention of the disease, and the toxin-producing organisms should be routinely isolated from the patient and the vehicle.
Journal ArticleDOI
Sources of Listeria monocytogenes contamination in a cold-smoked rainbow trout processing plant detected by pulsed-field gel electrophoresis typing
Tiina Autio,Sebastian Hielm,Maria Miettinen,Anna-Maija Sjöberg,Kaarina Aarnisalo,Johanna Björkroth,Tiina Mattila-Sandholm,Hannu Korkeala +7 more
TL;DR: Results show that the use of hot steam, hot air, and hot water seemed to be useful in eliminating L. monocytogenes from a cold-smoked rainbow trout processing plant, and the most contaminated sites of the processing plant were the brining and postbrining areas.
Journal ArticleDOI
Persistent Listeria monocytogenes strains show enhanced adherence to food contact surface after short contact times.
TL;DR: Results of this study reveal that persistent L. monocytogenes strains show enhanced adherence at short contact times, promoting their survival in food processing facilities and possibly having an effect on initiation of persistent plant contamination.
Journal ArticleDOI
Taxonomic study of Weissella confusa and description of Weissella cibaria sp. nov., detected in food and clinical samples
K. Johanna Björkroth,Ulrich Schillinger,Rolf Geisen,Norbert Weiss,Bart Hoste,Wilhelm H. Holzapfel,Hannu Korkeala,Peter Vandamme +7 more
TL;DR: The numerical analyses of Weissella confusa and Weisella cibaria strains did not reveal any specific clustering with respect to the origin of the strains, but the DNA-DNA reassociation experiment showed hybridization levels below 49% between the strains studied.
Journal ArticleDOI
Molecular Epidemiology of an Outbreak of Febrile Gastroenteritis Caused by Listeria monocytogenes in Cold-Smoked Rainbow Trout
TL;DR: Febrile gastroenteritis in five healthy persons was associated with the consumption of vacuum-packed cold-smoked rainbow trout containing Listeria monocytogenes.
