| a study of campylobacter jejuni and campylobacter coli in a river system. | campylobacter isolates were detected in 82.1% of river water samples moderately polluted with organic wastes. in the majority of the samples less than 10 campylobacter cfu/100 ml were detectable. the presence of waterfowl and the faecal contamination from a poultry-farm resulted in considerable higher campylobacter contents (greater than 240/100 ml). correlation studies showed a high correlation coefficient (p less than 0.05) between the number of campylobacters and that of total coliforms. camp ... | 1989 | 2684204 |
| campylobacter infection in humans. | campylobacter jejuni and campylobacter coli are now recognized as common bacterial cause of enteritis in humans. they infect the healthiest of persons resulting in a self-limiting diarrhoea often accompanied by mucus and blood in the stool. on the other hand c. fetus subsp fetus attacks otherwise debilitated persons whose body defences have been weakened by underlying conditions, and causes extragastrointestinal campylobacteriosis. c. pylori, which is able to survive in the stomach acid environm ... | 1989 | 2693070 |
| population genetics of human and animal enteric campylobacter strains. | a total of 125 strains of campylobacter jejuni and campylobacter coli from human and animal hosts were analyzed by multilocus enzyme electrophoresis. ten genetic loci were characterized by the electrophoretic mobilities of their products, and all were found to be polymorphic. the nine loci considered for genetic analysis had an average allele number of 6.9 and a mean genetic diversity of 0.634. the strains were grouped into 64 electrophoretic types (ets) forming two principal clusters; the first ... | 1989 | 2707852 |
| [antibiotic sensitivity of campylobacter jejuni and campylobacter coli strains with special reference to sensitivity to erythromycin and neomycin]. | 166 strains of c. jejuni and 46 strains of c. coli were typed against 14 antibiotics using the agar diffusion test. all strains were resistant against penicillin g, oxacillin and rifampicin. susceptibility were found against chloramphenicol, erythromycin, neomycin, oxytetracyclin, streptomycin and gentamycin. the minimal inhibition concentration was performed for erythromycin and neomycin. all strains tested were inhibited by less than or equal to 2 micrograms/ml neomycin, one strain was resista ... | 1989 | 2710556 |
| serological analysis of the heat-stable antigens involved in serotyping campylobacter jejuni and campylobacter coli. | analysis with serotyping antisera showed that carbohydrate determinants were the dominant heat-stable antigens of campylobacter jenuni/coli involved, whereas proteins did not contribute to the serological reactions. lipopolysaccharide (lps) along with a polysaccharide extract from whole bacteria (ps(wb] conferred strain serospecificity. in general, analysis with monoclonal antibodies in passive haemagglutination and co-agglutination tests showed the existence of similar antigenic determinants in ... | 1989 | 2713136 |
| evidence for posttranslational modification and gene duplication of campylobacter flagellin. | a gene encoding a flagellin protein of campylobacter coli vc167 has been cloned and sequenced. the gene was identified in a pbr322 library by hybridization to a synthetic oligonucleotide probe corresponding to amino acids 4 to 9 of the n-terminal sequence obtained by direct chemical analysis (s. m. logan, l. a. harris, and t. j. trust, j. bacteriol. 169:5072-5077, 1987). the dna was sequenced and shown to contain an open reading frame encoding a protein with a molecular weight of 58,945 and a le ... | 1989 | 2722741 |
| diversity of serotypes of campylobacter jejuni and campylobacter coli isolated in laboratory animals. | one hundred nineteen isolates of campylobacter jejuni and campylobacter coli from nine laboratory animal species were serotyped using antisera to 20 penner serotypes commonly isolated from cases of human enteric infections. although c. jejuni and c. coli were isolated from laboratory animals with diarrhea, the majority were cultured from asymptomatic animals (81%). seven of twenty-two isolates from animals with diarrhea were serotype 4 (32%) and three were serotype 1 (14%). sixty-one of the 119 ... | 1989 | 2724920 |
| immune response to campylobacter jejuni and campylobacter coli in a cohort of children from birth to 2 years of age. | a cohort of 111 children from bangui, central african republic, was surveyed for enteric campylobacter infections from birth to the age of 2 years; stools were examined biweekly in these children until 6 months of age and at least four times per year thereafter until 2 years of age and after each diarrheal episode. blood samples were obtained at birth and at 3, 6, 9, 12, 18, and 24 months of age. antibodies against glycine-extracted membrane antigens, purified flagella, and cholera toxin (ct) we ... | 1989 | 2744860 |
| in vivo antigenic variation of campylobacter flagellin. | campylobacter coli vc167 cells producing either antigenic phase 1 (p1) or phase 2 (p2) flagellins (as determined by characteristic protein and dna patterns) were used to infect rabbits by the removable intestinal tie-adult rabbit diarrhea (ritard) procedure. rabbits infected with p2 cells shed predominantly p2 cells throughout the infection; in rabbits infected with p1 cells, a transition of fecal isolates from p1 to p2 was observed. | 1989 | 2744863 |
| identification of campylobacter jejuni and c. coli by gel electrophoresis of the outer membrane proteins. | analysis of the electrophoretic profiles of the outer membrane proteins could be used to differentiate campylobacter jejuni (16 strains) from campylobacter coli (10 strains). this observation was confirmed by the study of dna homology obtained by a quantitative filter hybridization method. the hippurate hydrolysis test gave a poor correlation with the results of differentiation obtained by dna homology studies and outer membrane protein profile. | 1989 | 2745680 |
| enterotoxin production and serogroups of campylobacter jejuni and campylobacter coli from patients with diarrhea and from healthy laying hens. | enterotoxin production, a possible virulence factor, was determined in campylobacter jejuni and campylobacter coli by two different techniques, the cho cell test and the gm1 enzyme-linked immunosorbent assay. the frequency of enterotoxigenic campylobacter strains was 32% in strains from both humans with acute enteritis and healthy laying hens, as measured by the cho cell test. the cho cell test was significantly more sensitive than the gm1 enzyme-linked immunosorbent assay in the detection of en ... | 1989 | 2754001 |
| interaction of campylobacter species with antibody, complement and phagocytes. | the opsonisation of four different campylobacter species for human neutrophils was studied using a chemiluminescence system and electron microscopy. opsonisation of campylobacter fetus, campylobacter coli, and campylobacter jejuni was mediated by antibody and enhanced by complement. antibody was not, however, required for the phagocytosis of campylobacter pylori because it activates the classical pathway of complement directly. this unusual property may be important in the pathogenesis of c pylo ... | 1989 | 2788111 |
| in vitro activities of lomefloxacin and temafloxacin against pathogens causing diarrhea. | the in vitro activities of temafloxacin (a63004) and lomefloxacin (sc-47111; ny-198) were compared with those of seven other antibiotics against 146 isolates of bacterial enteric pathogens, including campylobacter jejuni and campylobacter coli. ciprofloxacin was the most active drug against the salmonella, shigella, yersinia, and vibrio spp. tested. lomefloxacin, temafloxacin, and difloxacin were the most active drugs tested against campylobacter spp. (mic for 90% of strains, 0.125 to 0.25 micro ... | 1989 | 2802563 |
