use of an ammonia electrode to study bacterial deamination of amino acids with special reference to d-asparagine breakdown by campylobacters.a method using an ammonia electrode is being developed for investigating the deamination of amino acids and amides by bacteria. application of this method to campylobacter jejuni and c. coli has led to the demonstration of d-asparaginase activity in some strains. this has allowed the subdivision of both species into d-asparaginase-positive and -negative biotypes. even though the method is in the developmental stage, it was found to be generally reproducible and easy to perform. areas for further ...19846501873
epidemiological investigations on campylobacter jejuni in households with a primary infection.fifty-four rotterdam patients in which a primary infection with campylobacter jejuni had been detected (index patients) were compared with 54 control subjects with regard to the consumption and preparation of foods 7 days before onset of illness and the keeping of pet animals. significantly more index patients than controls had eaten chicken meat (47 v. 29; p = 0.0002), particularly at barbecues (14 v. 2; p = 0.0015). marginally more index patients had eaten pork (47 v. 39; p = 0.048) or inadequ ...19846501878
a search for the source of campylobacter jejuni in milk.samples of milk from 1501 cows with mastitis were negative for campylobacter jejuni. the faeces of 74 healthy friesian cows were screened for c. jejuni: 13% of the samples were positive during the summer when the cows were on pasture, and 51% were positive in the winter when the cows were housed. positive samples contained on average 1 x 10(4) campylobacters per g faeces. it is concluded that faecal contamination rather than udder infection is the means by which campylobacters enter milk and the ...19846501879
a comparison of biotypes and serotypes of campylobacter sp. isolated from patients with enteritis and from animal and environmental sources.the origin of sporadic campylobacter infections has been investigated by means of a collaborative study. from a total of 1152 cases reported in north west england in 1982, campylobacter strains isolated during one month in each quarter of the year were biotyped and serotyped. for comparison, 875 strains of campylobacter isolated from environmental and animal sources were similarly examined. most strains from human beings were campylobacter jejuni; about half of them were of three serotypes. thos ...19846501895
chronic diarrhea and failure to thrive in an infant with campylobacter jejuni.we report the case of an infant with chronic diarrhea and failure to thrive. campylobacter jejuni was isolated from stools and treatment with erythromycin resulted in eradication of infection and prompt resolution of symptoms. a 22-month-old girl was referred to our university hospital because of weight loss and chronic diarrhea, which did not respond to repeated dietetic trials that excluded milk, gluten, and other foodstuffs. microscopic examination of the jejunal biopsy specimen revealed a mi ...19846502384
[etiological evaluation of acute diarrhea in children hospitalized in casablanca].a prospective study of pediatric diarrhea was conducted in casablanca. an etiologic agent was found in 67,8% of 87 ill participants. rotavirus was the most common cause while campylobacter jejuni, reported as rotavirus for the first time in morocco, was isolated in 11% of the patients.19846504575
comparison of antimicrobial susceptibility patterns of campylobacter jejuni and campylobacter coli.to determine whether employing antibiograms is useful to separate campylobacter jejuni and campylobacter coli, we determined the mics of 12 antibiotics for 104 human clinical strains and 74 swine strains. of 74 swine strains, 5 (7%) were hippurate positive, as were 93 (89%) of 104 human strains. the 12 antimicrobial agents tested were ampicillin, amoxicillin, clindamycin, chloramphenicol, erythromycin, furazolidone, norfloxacin, nalidixic acid, rosoxacin, rosaramicin, tetracycline, and sch 32063 ...19846508265

campylobacter jejuni associated diarrhea in commercially reared beagles.campylobacter jejuni was isolated from nine of ten (90%) juvenile beagles with diarrhea, compared with an isolation rate of five of eight (63%) from beagles which remained asymptomatic during the 2 month study. in four dogs, the diarrhea was recurrent and characterized by watery, mucoid, bile-streaked feces with occasional blood. elevated temperature and leukocytosis were noted in three of these dogs. two dogs with diarrhea also had giardia canis trophozoites.19846727288
comparative in vitro activity of ciprofloxacin against campylobacter spp. and other bacterial enteric pathogens.a comparison was made of the in vitro activity of ciprofloxacin (bay o 9867) with nine other antibiotics against isolates of campylobacter jejuni, salmonella spp., shigella spp., yersinia enterocolitica, clostridium difficile, vibrio spp., and escherichia coli. minimum inhibitory concentrations of ciprofloxacin were the lowest of any compound tested for all organisms except c. difficile.19846732220
campylobacter jejuni infections in haifa subdistrict, israel, summer 1981.a study investigating the clinical and epidemiological characteristics of campylobacter jejuni infections in an urban community in israel is presented. most of the information was obtained by interviewing 76 patients who constituted a systematic sample out of a total of 215 patients suffering from acute campylobacter jejuni diarrhoea during the summer of 1981. the crude annual incidence rate was 17 per 10 000. age-specific incidence rate in infants up to one year of age was eight times higher th ...19846735568
a study of the spread of campylobacter jejuni in four large kitchens.campylobacters were sought in swabs taken from work surfaces, sinks and floors of four kitchens-i.e. hospital, university, cook-freeze and commercial, processing frozen or fresh chickens. each kitchen was visited on four occasions. in the large commercial kitchen environmental contamination was found on each visit, whereas campylobacters were isolated on six of the twelve visits to the other kitchens. the hands of operatives were contaminated with campylobacters on only two of the 45 swabs taken ...19846736643
campylobacter enterocolitis in a neonatal nursery.during a five-day period, four neonates in a neonatal nursery developed campylobacter entercolitis. investigations suggested that cross-infection or common-source infection were unlikely and that the neonates acquired their infection during delivery from their respective mothers, three of whom were also found to harbour campylobacter jejuni in their stools. this suggestion was confirmed with use of the lior serotyping system in a blind fashion. each neonate was infected with a different serotype ...19846736679

properties of crude campylobacter jejuni heat-labile enterotoxin.the amount of crude campylobacter jejuni enterotoxin present in culture products was quantitated by comparing the response of these preparations with that of pure escherichia coli heat-labile toxin (lt) in the chinese hamster ovary assay and in enzyme-linked immunosorbent assays that used gm ganglioside or antisera to lt or both. maximum c. jejuni enterotoxin production was achieved by growth at 42 degrees c for 24 h under agitation in supplemented gc medium. adding polymyxin separately to eithe ...19846746090
dna relatedness among strains of campylobacter jejuni and campylobacter coli with divergent serogroup and hippurate reactions.eleven strains of campylobacter from earlier fluorescent-antibody studies were examined by dna hybridization to determine their species. three of the strains hydrolyzed sodium hippurate, and eight did not. four of the hippurate-negative strains were in campylobacter jejuni serogroups, and the remaining strains were in both c. jejuni and campylobacter coli serogroups. dna relatedness to type strains of c. jejuni and c. coli indicated that all three of the hippurate-positive strains and two of the ...19846746886
systematic investigation of enrichment media for wild-type campylobacter jejuni strains.of the media examined, thioglycolate broth supplemented with 5% lysed sheep blood, butzler antibiotic mixture, and 0.1% lauryl sulfate was the most sensitive enrichment medium for recovery of wild-type strains of campylobacter jejuni from cecal contents of chickens and chicken livers. it allowed the retrieval of 1 cfu as did solid media but permitted the screening of 50-times larger volumes. double-strength enrichment medium required 5 to 10 cfu for growth. omission of lauryl sulfate reduced the ...19846746890
antibiotic sensitivity patterns of campylobacter jejuni/coli isolated from laboratory animals and pets.fifty-four strains of campylobacter jejuni/coli isolated from a variety of species of laboratory animals as well as pet dogs were tested by an agar dilution technique for susceptibility to each of 12 antimicrobial agents. gentamicin and furazolidone were the most active of the drugs examined. the strains tested frequently were sensitive to two other aminoglycoside antibiotics, neomycin and kanamycin. erythromycin also was effective at levels achievable in serum except in three strains which were ...19846748605
[campylobacter jejuni gastroenteritis].acute gastroenteritis is a major cause of hospital admission with attendant morbidity and occasional mortality. campylobacter jejuni recently has been recognized as a common cause of acute bacterial gastroenteritis in children and adults. its frequency of isolation is comparable to and in many studies exceeds that of salmonella isolations from diarrheal stools of hospitalized patients. medical workers in many parts of the world confirmed that campylobacter jejuni was found more commonly in feces ...19846748977
campylobacter enteritis. a 3-year experience.campylobacter jejuni was isolated from 135 infants and children seen at the oklahoma children's memorial hospital over a 3-year period. the comparative frequency of isolation of c. jejuni, salmonella, and shigella were 1.5 percent, 2.2 percent, and 3.1 percent, respectively. campylobacter enteritis was most prevalent during the warm months from may to october, peaking in july. seventy percent of the afflicted children were 2 years old or younger; only 13 percent were older than 5 years. there we ...19846609793
[sensitivity of campylobacter jejuni/coli to 11 antibiotics].the antimicrobial susceptibility of 106 strains of campylobacter jejuni/coli recovered from animals and humans was studied using broth microdilution panel. human and animal strains exhibit similar susceptibility, with the exception of the strains from pigs which are more resistant to erythromycin and clindamycin. among the hippurate negative strains (c. coli), these strains are also recognizable from those recovered from other hosts.19846611534
