avian wildlife reservoir of campylobacter fetus subsp. jejuni, yersinia spp., and salmonella spp. in norway.	cloacal swabs from 540 wild-living birds were cultured for campylobacter fetus subsp. jejuni, yersinia spp., and salmonella spp. the carrier rates detected were as follows: c. fetus subsp. jejuni, 28.4%; yersinia spp., 1.2%; and salmonella spp., 0.8%. all birds were apparently healthy when captured. c. fetus subsp. jejuni was isolated from 11 of the 40 bird species examined. among birds inhabiting the city of oslo, the highest isolation rate was found in crows (corvus corone cornix) (89.8%), fol ...	1983	6338824
serotyping of campylobacter jejuni isolated from sporadic cases and outbreaks in northern norway.	in the northern regions of norway, 123 cases of campylobacter jejuni gastroenteritis were either sporadic infections or due to five separate outbreaks during 1980-83. using a serotyping scheme based on thermostable antigens and the passive haemagglutination technique, 92 isolates were serotyped. excluding duplicates from the outbreaks, the serotype distribution based on 79 isolates showed that serotypes 6, 7 and 12, 40 were the most frequent in occurrence. each included 11 (13.9%) of the isolate ...	1985	4013744
characterization of cross-reacting serotypes of campylobacter jejuni.	some strains of campylobacter jejuni react with more than one reference antiserum from the serotyping scheme based on heat-stable lipopolysaccharide antigens. to investigate the molecular basis of these cross-reactions, lipopolysaccharides from the reference strains for serotypes 4, 13, 16, 43, and 50 and isolates recovered during two different outbreaks of c. jejuni enteritis were analyzed by passive haemagglutination and sodium dodecyl sulphate-polyacrylamide gel electrophoresis coupled with s ...	1989	2472859
campylobacter spp., salmonella spp., verocytotoxic escherichia coli, and antibiotic resistance in indicator organisms in wild cervids.	faecal samples were collected, as part of the national health surveillance program for cervids (hop) in norway, from wild red deer, roe deer, moose and reindeer during ordinary hunting seasons from 2001 to 2003. samples from a total of 618 animals were examined for verocytotoxic e. coli (vtec); 611 animals for salmonella and 324 animals for campylobacter. a total of 50 samples were cultivated from each cervid species in order to isolate the indicator bacterial species e. coli and enterococcus fa ...	2005	16108210
antimicrobial resistance in campylobacter jejuni from humans and broilers in norway.	in this study comprising isolates from 2001 to 2003, resistance was considerably more widespread among campylobacter jejuni from humans infected abroad than infected within norway. the discrepancy was particularly notable for fluoroquinolone resistance (67.4% vs. 6.5%). this is probably a reflection of a low resistance prevalence in norwegian broiler isolates (1.2% fluoroquinolone resistant).	2006	16409659
relative importance of abnormalities of cck and 5-ht (serotonin) in giardia-induced post-infectious irritable bowel syndrome and functional dyspepsia.	post-infectious irritable bowel syndrome (pi-ibs) and functional dyspepsia (fd) have been described after both campylobacter jejuni gastroenteritis and giardia infection. after c. jejuni, there is increased rectal serotonin (5-ht)-containing ec cells and postprandial plasma 5-ht, while a pilot study suggested increased plasma cholecystokinin (cck) after giardia infection.	2010	20132151
