microbiological analysis of seed sprouts in norway.	as part of larger survey of microbial contamination of fruits and vegetables in norway, four different sprouted seed products were analysed for bacterial and parasitic contaminants (n = 300 for bacterial analyses and n = from 17 to 171 for parasite analyses, depending on parasite). escherichia coli o157, salmonella, listeria monocytogenes, cyclospora oocysts, ascaris eggs and other helminth parasites were not detected in any of the sprout samples. thermotolerant coliform bacteria (tcb) were isol ...	2002	11999108
influence of bovine manure as fertilizer on the bacteriological quality of organic iceberg lettuce.	to investigate the bacteriological quality, and the occurrence of selected pathogenic bacteria from organically grown iceberg lettuce fertilized with bovine manure in the form of compost, firm manure and slurry in a 2-year field trial.	2004	15012817
multiple-locus variable-number tandem-repeats analysis of listeria monocytogenes using multicolour capillary electrophoresis and comparison with pulsed-field gel electrophoresis typing.	the multiple-locus variable-number tandem-repeats analysis (mlva) method for genotyping has proven to be a fast and reliable typing tool in several bacterial species. mlva is in our laboratory the routine typing method for salmonella enterica subsp. enterica serovar typhimurium and escherichia coli o157. the gram-positive bacteria listeria monocytogenes, while not isolated as frequent as s. typhimurium and e. coli, causes severe illness with an overall mortality rate of 30%. thus, it is importan ...	2008	18096258
listeria monocytogenes associated kerato-conjunctivitis in four horses in norway.	listeria monocytogenes has been reported to cause various infectious diseases in both humans and animals. more rarely, ocular infections have been reported. to our knowledge, only two cases of listeria keratitis have been described in horses. we report kerato-conjunctivitis in four norwegian horses associated with l. monocytogenes. clinically, all cases were presented with recurrent unilateral kerato-conjunctivitis. l. monocytogenes bacteria were isolated from swab samples from all cases, and cy ...	2015	26552393
