| outer membrane components of campylobacter hyointestinalis. | outer membranes were isolated, by sodium lauryl sulphate extraction, from the american type strain, five australian, and four english isolates of campylobacter hyointestinalis. on sds-page examination, the protein profiles of seven strains (including the type strain) were similar, and were dominated by two major proteins of 47 and 50 kda. three other isolates had unique major protein profiles. the largest of these proteins was heat-modifiable in these isolates, and in the type strain. the flagel ... | 1992 | 1624127 |
| variation in antigenicity and molecular weight of campylobacter coli vc167 flagellin in different genetic backgrounds. | campylobacter coli vc167 has been shown to undergo a reversible flagellar antigenic variation between antigenic type 1 (t1) and antigenic type 2 (t2). vc167 contains two flagellin genes, and the products of both genes are incorporated into a complex flagellar filament in both antigenic types. although there are only minor amino acid changes in the flagellins expressed by t1 and t2 cells, the two antigenic types of flagellins can be distinguished by differences in apparent m(r) on sodium dodecyl ... | 1992 | 1624417 |

| recovery of viable but non-culturable campylobacter jejuni. | suspensions of campylobacter jejuni became non-culturable after storage in sterilized pond water at 4 degrees c for periods between 18 and 28 d, depending on the strain. suspensions of four strains of c. jejuni that had been in water for 6 weeks, and shown to be non-culturable, were fed to suckling mice. colonization of mice was established with two of the strains and failed with the other two strains. examination of these suspensions under the electron microscope showed some cocci having the ap ... | 1991 | 1770362 |
| electron microscopic appearance of the chronic campylobacter jejuni enteritis of mice. | campylobacter jejuni is a major cause of human enteritis which mimics the inflammatory bowel disease (ibd). in this study, microstructural changes on the surfaces of the murine gastrointestinal tract persistently colonized by campylobacter jejuni, strain gj-s131, were investigated by using scanning electron microscopy (sem) and transmission electron microscopy (tem). the results revealed that the appearance of the gastrointestinal mucosa in both balb/c and km mice resembled that in human with in ... | 1991 | 1782809 |
| identification, purification, and characterization of major antigenic proteins of campylobacter jejuni. | evidence from developing countries and volunteer studies indicates that immunity to campylobacter jejuni and campylobacter coli may be acquired, but the antigenic basis for this protection is poorly defined. we have purified to homogeneity four proteins with molecular weights of 28,000 (peb1), 29,000 (peb2), 30,000 (peb3), and 31,000 (peb4) from epidemic c. jejuni strain 81-176 using acid extraction and sequential ion-exchange, hydrophobic interaction, and gel filtration chromatography. the rela ... | 1991 | 1885571 |

| phagocytosis and intracellular killing of campylobacter jejuni by elicited chicken peritoneal macrophages. | in vitro phagocytosis and intracellular survival of campylobacter jejuni (strains b540 and clin 1) in chicken peritoneal macrophages were studied. macrophages were induced with sephadex g-50 and harvested 48 hr later by peritoneal lavage. the extent of phagocytosis over time was determined by enumerating the intracellular c. jejuni after removal of extracellular c. jejuni with gentamicin. pre-incubation of c. jejuni with antiserum generally enabled the macrophages to ingest greater numbers of ce ... | 1991 | 1786008 |
| childhood diarrhoea in a low-income urban community in bangkok: incidence, clinical features, and child caretaker's behaviours. | a one-year surveillance study of childhood diarrhoea in a low-income urban community in bangkok revealed an annual incidence of 2.2 episodes per child among infants, and that the overall annual incidence among children under five years of age was 0.9 per child. rotavirus, salmonella and campylobacter jejuni were common aetiologic agents. in children less than one year, diarrhoea was caused mostly by rotavirus and salmonella. in 1-2 year old children, the major causative agent was rotavirus while ... | 1991 | 1787280 |
| [in vitro antimicrobial activity of rokitamycin, a macrolide antibacterial agent, against clinically isolated strains of campylobacter and other enteritis-causing bacteria]. | we determined the minimum inhibitory concentrations (mics) of rokitamycin (tms-19-q, rkm), a macrolide antimicrobial agent, against strains of various bacterial species isolated from enteritis patients, and compared them with those of josamycin (jm), erythromycin (em) and ofloxacin (oflx). mic90 of rkm against 147 strains of campylobacter jejuni, and each 25 strains of shigella spp., salmonella spp. and diarrheagenic escherichia coli were 1.56, 200, 800 and 200 micrograms/ml, respectively. there ... | 1991 | 1791330 |

| [bacterial ileocecitis: a "new" disease]. | in cases of clinical suspicion of an acute appendicitis sonography uncovers another disease as the real cause of the symptoms in about one-quarter of such cases. bacterial ileocaecitis is most frequently diagnosed (11.6% of n = 786). in special bacteriological stool cultures, yersinia enterocolitica and campylobacter jejuni were identified, whereas salmonella enteritidis was a rarer finding. the typical sonographic manifestation of bacterial ileocaecitis compared against crohn's disease of the i ... | 1991 | 1796286 |
| comparison of the survival of campylobacter jejuni and campylobacter coli in culturable form in surface water. | six campylobacter jejuni and six campylobacter coli strains were isolated from cows and pigs, and their survival in lake water was compared by viable counts. campylobacter jejuni survived longer in culturable form than c. coli in untreated and membrane-filtered water both at 4 and 20 degrees c. this difference in survival time may be a reason why c. jejuni is generally isolated from surface waters more frequently than c. coli. both species survived better in filtered than in untreated water. thi ... | 1991 | 1913357 |
| [the adhesive properties of bacteria of intestinal origin]. | differences between strains of nonpathogenic escherichia and lactobacilli, as well as some pathogenic bacteria of enteric origin (escherichia, shigella, campylobacter), in their capacity to adhesion to rat enteric and colonic cells have been shown in vitro. the strains under study have been found to possess more pronounced adhesiveness with respect to colonic cells, which is indicative of their higher receptive capacity in comparison with enteric cells. in the absence of normal microflora lactob ... | 1991 | 1801491 |

| the effect of lactic acid sprays on campylobacter jejuni inoculated onto poultry carcasses. | spraying poultry carcasses with 1% lactic acid 10 min after inoculation with campylobacter jejuni, resulted in a significant reduction in the number of the bacteria after 4 h at 4 degrees c. some of the inoculated cells, however, survived for at least 144 h. spraying 10 min after inoculation with 2% lactic acid, totally eliminated all inoculated c. jejuni within 24 h. on the other hand, spraying 24 h after inoculation, with either 1% or 2% lactic acid did not eliminate all the bacteria. inoculat ... | 1991 | 1818508 |
| intestinal colonization of rats following experimental infection with campylobacter jejuni. | oral infection of rats with 10(6)-10(8) colony forming units per ml of campylobacter jejuni resulted in prompt intestinal colonization. campylobacter jejuni was recovered from rat faecal samples for four months post infection. the colonized rats did not succumb to clinical diarrhoea or pyrexia. the resistance of rats to c. jejuni clinical infection and their ability to shed the organism for protracted periods, make rats potential source of zoonotic campylobacteriosis. | 1991 | 1935728 |
| [resistance to chemotherapy of campylobacter jejuni strains]. | sensitivity to 22 different chemotherapeutic agents against 31 campylobacter jejuni strains, isolated from children was determined. most of the investigated strains were sensitive to doxycycline, chloramphenicol and nitrofurantoin (90-100) and 84-87% of them to oxy-tetracycline augmentation, ofloxacin, erythromycin. all the strains were resistance to: cephalotin, cephadrin, cefuroxime and cefoperazone and 77-87% to ceftazidime, colistin and vancomycin. | 1991 | 1819812 |
