[who discovered campylobacter jejuni/coli? a review of hitherto disregarded literature].non culturable spiral form bacteria were noted in 1886 by theodor escherich. he found them in stool specimens and large intestinal mucous associated with diarrhoea in neonates as well as in kittens. in the following years till the end of the century a number of mainly german language publications appeared, describing the occurrence of such "spirilla" in cases of "cholera-like" and "dysenteric" disease. these organisms were found mainly in the colon or associated with mucous in diarrheal stool sp ...19863526758
antibody response in patients infected with one common strain of campylobacter jejuni. evidence for production of antibodies against thermostable soluble antigens.antibody production was investigated for ten patients from a group of 20 who had contracted infections with a strain of campylobacter jejuni of serotype pen 6,7. production of antibody was determined by titrating ten sets of paired sera for agglutination of formalin-treated and heat-treated cell suspensions and by passive hemagglutination using both sheep and human o rh-red blood cells sensitized with extracted soluble thermostable antigens. all patients had demonstrable antibodies against the f ...19863528928
[experience in isolating campylobacter jejuni from patients with acute intestinal diseases].erythrite agar, a commercial culture medium produced by the research institute for culture media (makhachkala, ussr), is suitable for the cultivation of c. jejuni after the addition of hemolized sheep blood. the addition of antibiotics to the medium permits its use for the isolation of c. jejuni from feces. by means of this medium c. jejuni has been isolated from the feces of 10% of patients hospitalized on account of acute infectious intestinal diseases.19863529758
[epidemiologic evaluation of a sample of 91 rats (rattus norvegicus) captured in the sewers of lyon].91 rats captured in 1982 in the sewers of lyon (france) have been examined for the presence of some microorganisms implicated in infections transmissible to man, by direct examination, bacteriological culture or detection of specific antibodies. bacteriological results have shown a high proportion of carriers of yersinia enterocolitica and frederiksenii (29%), of pasteurella pneumotropica (29%), of staphylococcus aureus (53%), and of campylobacter jejuni (18%), a low proportion of carriers of sa ...19863532637
direct immunofluorescence microscopy for rapid screening of campylobacter enteritis.diagnostic use of a direct fluorescent-antibody test for detection of campylobacter jejuni and c. coli in human fecal specimens (n = 497) was compared with detection by culturing (specificity, 99.7%; sensitivity, 40%). conjugates were prepared from immunoglobulin g antibody against 22 lior c. jejuni and c. coli reference strains (h. lior, d. l. woodward, j. a. edgar, l. j. laroche, and p. gill, j. clin. microbiol. 15:761-768, 1982). interestingly, the serotypes of cultures tested by the direct f ...19863533990

the comparative activity of pefloxacin, enoxacin, ciprofloxacin and 13 other antimicrobial agents against enteropathogenic microorganisms.in this study, we compared the activity of pefloxacin, enoxacin and ciprofloxacin against 269 enteropathogenic strains (campylobacter jejuni, enteropathogenic escherichia coli, salmonella typhi, shigella spp., vibrio cholerae and yersinia enterocolitica) with that of rosoxacin, flumequin, nifuroxazide, erythromycin, chloramphenicol, ampicillin, cefotaxime, tetracycline, amikacin, netilmicin, sulfamethoxazole, trimethoprim and co-trimoxazole. pefloxacin, enoxacin and ciprofloxacin were always amo ...19863546145
approaches to the detection of enteric pathogens, including campylobacter, using nucleic acid hybridization.a previous study of the detection of campylobacter jejuni in fecal samples spotted directly onto nitrocellulose filters before hybridization revealed a relatively low sensitivity and some false-positive results. we have investigated two factors that interfere with the detection of campylobacter jejuni in fecal samples: interfering substances that create false-positive background signals and nonspecificity of the probe. heterologous deoxyribonucleic acid probes bound nonspecifically to partially ...19863698541
detection of pathogenic campylobacter species in blood culture systems.because differences in recognition of campylobacter fetus and campylobacter jejuni in systemic infections may be due partially to differences in the ability to cultivate these organisms, we studied their growth characteristics in two widely used blood culture systems. in the roche septi-chek system (hoffman-la roche, inc., nutley, n.j.), over a broad range of inocula all strains were detected in broth within 2 days and on paddles within 3 days. in the bactec 6b aerobic bottles (johnston laborato ...19863700626
the protection of infant mice from colonization with campylobacter jejuni by vaccination of the dams.intraperitoneal vaccination of female mice, before mating, with a whole cell, heat-killed (62 degrees c) vaccine of campylobacter jejuni allowed the mother to confer immunity to her young, challenged orally 4-6 days after birth with the homologous strain. there was no protection against a strain of another serotype. heating the vaccine to 100 degrees c destroyed its protective properties. a vaccine prepared from an aflagellate variant of the original strain was as protective as the original vacc ...19863701036
campylobacter jejuni in broilers: the role of vertical transmission.the role of broiler eggs in the transmission of campylobacter jejuni to broiler grow-out flocks was investigated. six breeder flocks supplying broiler eggs to hatcheries were examined for cloacal carriage of c. jejuni. of 240 birds tested, 178 (74%) were c. jejuni-positive. eggs from these birds examined for c. jejuni penetration of the egg shell indicated that 185 of 187 were campylobacter-free. eggs from breeder flocks of unknown c. jejuni status were also examined for c. jejuni shell penetrat ...19863701037
the cellular fatty acid composition of campylobacter species isolated from cases of enteritis in man and animals.the cellular fatty acid composition of 41 strains of suspected campylobacter jejuni, 23 from human cases of gastroenteritis and 18 from animals, was examined by gas-liquid chromatography. three of the 23 human isolates and 2 of 18 animal isolates did not contain 19:0 cyclopropane fatty acid and were identified as c. laridis. the remaining 36 strains had cellular fatty acid profiles consistent with c. jejuni but could be divided into three groups on the ratio of the concentration of 18:1 and 19:0 ...19863701040

persistence of multiply antibiotic-resistant campylobacter jejuni in a patient with the acquired immune deficiency syndrome.chronic diarrhea due to campylobacter jejuni has been described in patients with hypogammaglobulinemia. a patient with the acquired immune deficiency syndrome (aids) and normal total serum immunoglobulins had persistent diarrhea and c. jejuni on stool culture for seven and a half months despite repeated antibiotic therapy. antibiotic sensitivity studies revealed the c. jejuni to be multiply antibiotic-resistant. evaluation of the mechanism of resistance showed the organism harbored a conjugative ...19863706381
susceptibility of campylobacter jejuni to strain-specific bactericidal activity in sera of infected patients.campylobacter jejuni is a common cause of inflammatory enteritis, which in normal hosts is usually self-limited and resolves without antibiotic therapy. c. jejuni bacteremia is very rare. we examined sera for bactericidal activity that might be important in limiting the extent of c. jejuni infection in man. we studied the ability of nonimmune sera and homologous and heterologous immune sera from infected patients to kill different fresh case isolates of c. jejuni in vitro. the reduction of the l ...19863710581
enzyme-linked immunosorbent assays for virulence properties of campylobacter jejuni clinical isolates.to evaluate the capacity of enzyme-linked immunosorbent assays (elisas) to identify pathogenic strains among clinical fecal isolates of campylobacter jejuni, 40 consecutively obtained strains from 39 sick patients and 1 asymptomatic person were tested by respective elisas for enterotoxin production in culture filtrates and for the invasive virulence antigen of bacterial cells. of the 40 strains, 14 produced the enterotoxin; 15 strains, two of which were also enterotoxigenic, were invasive; and 1 ...19863711295
