| bovine genital campylobacteriosis (vibriosis): vaccination of experimentally infected bulls. | the therapeutic efficacy of a campylobacter fetus subsp venerealis bacterin was determined in experimentally infected bulls. ten of twelve 5-year-old angus bulls became infected after being infused intrapreputially with c fetus subsp venerealis. of the 10 bulls, 6 were vaccinated with 5 ml of c fetus subsp venerealis vaccine on 2 occasions 4 weeks apart. preputial washings of the vaccinated bulls were culturally negative by the 8th week after primary vaccination. none of the 18 heifers exposed t ... | 1983 | 6194723 |
| [campylobacter infection in children]. | enteritis by campylobacter jejuni/coli is by far the most frequent clinical entity of campylobacter-infection. it may be compared to salmonella-enteritis as for its epidemiologic importance. the course of the disease may be dramatic, but can be successfully treated as soon as the pathogen is known. in prematures and newborn babies infections with campylobacter fetus ssp. fetus are life-threatening and early diagnosis is of life-saving importance. five observations of campylobacter-enteritis in c ... | 1983 | 6352463 |
| value of stool examination in patients with diarrhoea. | findings of stool examinations in 1593 patients with diarrhoea due to a single enteric pathogen--enterotoxigenic escherichia coli rotavirus, shigella, campylobacter jejuni, vibrio cholerae 0:1, entamoeba histolytica, or giardia lamblia--were reviewed to determine how well they predicted the agent associated with the diarrhoea. specimens were examined visually for blood and mucus, tested for ph, and examined under a microscope for the presence of red and white blood cells, parasites, and stool fa ... | 1983 | 6307460 |
| the polymicrobial origin of intestinal infections in homosexual men. | to determine the microbial cause and the clinical and pathologic correlates of anorectal and intestinal symptoms in homosexually active men, we performed comprehensive microbiologic studies, anoscopy, sigmoid-oscopy, and rectal biopsy in men examined in a clinic for sexually transmitted diseases. enteric pathogens were found in 95 of 119 consecutive homosexual men with anorectal or intestinal symptoms and in 29 of 75 randomly selected homosexual men without such symptoms (p less than 0.001). the ... | 1983 | 6308444 |
| application of serotyping and chromosomal restriction endonuclease digest analysis in investigating a laboratory-acquired case of campylobacter jejuni enteritis. | a frequently passaged laboratory strain of campylobacter jejuni was confirmed by serotyping on the basis of thermostable antigens and by bacterial chromosomal restriction endonuclease digests to be the causative agent of enteritis in a laboratory worker. | 1983 | 6317712 |
| nucleic acids in the classification of campylobacters. | the importance of campylobacters in human disease has stimulated improvements in the methods for identification of strains from hospitals and the environment. reliable and accurate identification depends on a sound classification for which nucleic acid analyses provide fundamental information about species relationships. studies on the genus campylobacter show that the genome dna of species have base compositions of 29 to 38 mol% g + c and molecular weights of 1.54 x 10(9) to 2.31 x 10(9). campy ... | 1983 | 6194994 |
| effects of disinfectants on campylobacter jejuni. | because of the increasing recognition that campylobacter jejuni is an important enteric pathogen of humans, we studied the effects of widely used disinfectants on the viability of this organism. at an inoculum size of 10(3) to 10(4) cfu/ml, 1.25 mg of hypochlorite per liter killed three strains within 1 min. at an inoculum size of 10(6) to 10(7) cfu/ml, 5 mg of hypochlorite per liter killed three strains within 15 min. killing of similar concentrations of c. jejuni and escherichia coli by hypoch ... | 1983 | 6305266 |
| a study of the oxygen and carbon dioxide requirements of thermophilic campylobacters. | the oxygen and carbon dioxide requirements of different biotypes of thermophilic campylobacters were investigated by means of (a) quantitative studies, and (b) total growth studies. oxygen tolerance of the five test organisms differed markedly and varied with the carbon dioxide concentration. at most carbon dioxide concentrations tested, campylobacter jejuni strains nctc 11168 and nctc 11392 tolerated 21% oxygen (growth reduced), c coli nctc 11353 tolerated 15% oxygen (growth reduced), and c jej ... | 1983 | 6408142 |
| characterization of tetracycline resistance plasmids from campylobacter jejuni and campylobacter coli. | tetracycline resistance in strains of campylobacter jejuni and campylobacter coli was mediated by plasmids. intra- and interspecies transfer was demonstrated within the genus campylobacter. buoyant densities of plasmid dnas ranged from 1.691 to 1.694 g/cm3 (31 to 33% guanine plus cytosine). restriction enzymes acci, bcli, bglii, and psti were found to be most useful for comparing the plasmids. the molecular weight of c. jejuni plasmid pmak175 was 44.7 kilobases (29 x 10(6), and the other plasmid ... | 1983 | 6318666 |
| biphasic culture system for rapid campylobacter cultivation. | we developed a biphasic culture system consisting of 4 ml of brucella agar (ba) and 6 ml of brucella broth (bb) in 25-cm2 tissue culture flasks, which were incubated in air (bb/baa) or in a gas mixture of 5% o2, 10% co2, and 85% n2 (bb/bag). these media were also used with a supplement consisting of ferrous sulfate, sodium metabisulfite, and sodium pyruvate and incubated as above (fb/faa and fb/fag, respectively). highly satisfactory growth of campylobacter jejuni 301 was obtained with all mediu ... | 1983 | 6401980 |
| 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 |
| serogroups of campylobacter jejuni, campylobacter coli, and campylobacter fetus defined by direct immunofluorescence. | rabbits were inoculated with whole, formalinized campylobacter jejuni, c. coli, and c. fetus cells; the c. jejuni and c. coli immunogens were identified by their dna relatedness at the species level to the type strains of c. jejuni or c. coli. the designation c. coli was not used among the other c. jejuni strains; they were classified as hippurate-positive or hippurate-negative c. jejuni. immunoglobulin g was isolated from the antisera and labeled with fluorescein isothiocyanate. these conjugate ... | 1983 | 6341405 |
| an acid extract as a common antigen in campylobacter coli and campylobacter jejuni strains. | an acid extract prepared from a single strain of campylobacter jejuni reacted with rabbit antisera against 21 strains of c. jejuni and campylobacter coli. the immunogen is resistant to formalin and to exposure to 100 degrees c for 30 min. the antigenic extract may have practical applications in human serology. | 1983 | 6343426 |
| isolation of campylobacter jejuni from an appendix. | campylobacter jejuni skirrow biotype 1, lior serotype 8 was isolated from the appendix of an 11-year-old boy who had a 6-h history of acute abdominal pain. histological diagnosis on the appendix section was early acute appendicitis. dilute carbol fuchsin stain and indirect fluorescent antibody test performed on the appendix section also revealed the presence of campylobacter sp. the patient developed a significant bactericidal antibody titer of 1,024, providing substantial clinical evidence of t ... | 1983 | 6352736 |
| evaluation of transport media for campylobacter jejuni in human fecal specimens. | it is not always possible to culture feces immediately, and appropriate methods for transport of human specimens, unlike those from animals, have not been fully evaluated. therefore, we took serial subcultures in two phases from six transport media inoculated with human diarrheal stools known to be positive for campylobacter jejuni. in phase 1, cary-blair medium and buffered glycerol saline did not preserve c. jejuni as well as did alkaline peptone-water (apw), modified cary-blair medium, thiogl ... | 1983 | 6355160 |

| correlation of an expanded direct fluorescent-antibody system with an established passive hemagglutination system for serogrouping strains of campylobacter jejuni and campylobacter coli. | rabbits were inoculated with whole, formalinized cells from eight passive hemagglutination reference strains of campylobacter. fluorescein isothiocyanate-labeled immunoglobulin g from these antisera defined seven new direct fluorescent-antibody serogroups of c. jejuni and one new serogroup of c. coli. this expanded the campylobacter direct fluorescent antibody system to include 17 serogroups of c. jejuni, 3 serogroups of c. coli, and 2 serogroups of c. fetus. we then compared the passive hemaggl ... | 1983 | 6358249 |
| is enrichment culture necessary for the isolation of campylobacter jejuni from faeces? | the role of enrichment culture for the isolation of campylobacter jejuni from faeces is discussed. it is concluded that enrichment culture is only necessary for those specimens where it is anticipated that the number of organisms is likely to be low. in a trial of a blood free enrichment broth (ccd broth) and the modified preston enrichment broth the latter gave significantly superior results. | 1983 | 6361073 |
| evaluation of filters for recovery of campylobacter jejuni from water. | campylobacter jejuni has been incriminated in several large waterborne outbreaks, but it has rarely been isolated from water itself. better methodology is needed for the isolation of c. jejuni from water. we evaluated three types of 0.45-micron microporous filters and three different pore sizes of positively charged depth filters for their ability to recover c. jejuni from seeded, sterile tap and surface water. the microporous filters tested were millipore ha, gelman gn6, and zetapor. three pore ... | 1983 | 6360048 |
| the microbial evaluation of acute cellulitis. | twenty consecutive patients with acute cellulitis were studied by retrospective chart review. patients with suffusion and edema, with or without vesicles, were included. patients with breaks in the skin, with focal suppurations or with concurrent antimicrobial therapy were excluded. in nineteen of the twenty patients, aspirates (95 percent) failed to grow organisms. pasteurella multocida was grown from subcutaneous aspirate and blood cultures of a single patient; he was immunocompromised by wald ... | 1983 | 6602690 |
| hla-b27-negative arthritis related to campylobacter jejuni enteritis in three children and two adults. | five out of 37 patients with proven campylobacter jejuni enteritis developed arthritis. two adult patients presented with classical reiter's syndrome. one of the three children had reactive arthritis, and clinical suspicion of septic arthritis could not be confirmed in two. the acute synovitis subsided usually without treatment in all patients within 3-7 days, while arthralgia persisted longer in 4 patients. hla-b27 was not present in the 5 patients with arthritis, but was found in 4 others. in ... | 1983 | 6605028 |
| a case of a double infection with salmonella typhi and campylobacter fetus subspecies jejuni. | a case of a double infection with salmonella typhi and campylobacter subspecies jejuni proven by isolation and serology is reported. the patient was effectively treated with erythromycin and chloramphenicol. | 1983 | 6612785 |
| electron microscopy of the coccoid form of campylobacter jejuni. | confluent cultures of campylobacter jejuni incubated for 24 and 48 h each were examined by electron microscopy. although the 24-h-old cells exhibited typical curved morphology, the 48-h-old cells showed rounded morphology with a loss of cell integrity. this appeared to be an autolytic process that occurred very rapidly after the culture became mature. these results confirm previous evidence that the coccoid form of this organism is a degenerate state. | 1983 | 6619291 |
