genome map of campylobacter fetus subsp. fetus atcc 27374.a physical map of the chromosome of campylobacter fetus subsp. fetus was constructed by using pulsed-field gel electrophoresis of restriction fragments generated by sali, smai and noti. digestion of the type strain atcc 27374 with these restriction endonucleases resulted in generating 4-14 fragments. the order of the fragments was deduced from hybridization of these restriction fragments to southern blots of pulsed-field gel electrophoresis gels generated by the other two enzymes. the estimated ...19957590179
in vivo pefloxacin-resistant campylobacter fetus responsible for gastro-intestinal infection and bacteremia associated with arthritis of the hip.the authors report a case of campylobacter fetus subsp. fetus gastro-intestinal infection and bacteremia with poly-arthritis, mainly of the hip, in a french patient simultaneously suffering from cirrhosis of the liver. the outcome was eventually favorable, however only after a trial of ineffective pefloxacin-gentamicin therapy. the authors suggest: (i) gentamicin should not be given alone in c. fetus subsp. fetus infections, and (ii) pefloxacin should not be given if antibiotic sensitivities dat ...19957618366
iatrogenic compressive lumbar myelopathy and radiculopathy in adult cattle following injection of an adjuvanted bacterin into loin muscle: histopathology and ultrastructure.compressive lumbar myelopathy is a recognized iatrogenic complication of injecting water-in-oil vaccines into paravertebral sites of laboratory animals and chickens. herein, we report the histologic and ultrastructural features of a similar complication in a herd of cattle. iatrogenic posterior paresis developed over 34 days in 56 of 610 cows (9.2%) following injection of a commercial bacterin 11-34 days earlier into m. longissimus lumborum. the bacterin was composed of inactivated escherichia c ...19957619907
analysis of strains of campylobacter fetus by pulsed-field gel electrophoresis.campylobacter fetus chromosomal dna from 21 strains was analyzed by pulsed-field gel electrophoresis. the fingerprint patterns generated with smai and sali were distinctive. using the profiles obtained by pulsed-field gel electrophoresis, we established the phylogenetic dendrogram of c. fetus to identify the genetic relationship of the strains.19957650215
a survey of campylobacter bacteremia in three danish counties, 1989 to 1994.over a 5-year period (april 1989 to march 1994) bacteremia caused by campylobacter species was diagnosed in 15 patients in a population of 1.3 million in three counties in jutland province, denmark. the incidence was 0.2/100,000/year and the ratio of blood to fecal isolates, was 0.008. campylobacter coli and campylobacter jejuni accounted for 6 cases each, campylobacter fetus for 2, and in 1 case the species diagnosis was uncertain. seven patients were males and 8 females; median age was 42 (ran ...19957660078
shift in s-layer protein expression responsible for antigenic variation in campylobacter fetus.campylobacter fetus strains possess regular paracrystalline surface layers (s-layers) composed of high-molecular-weight proteins and can change the size and crystalline structure of the predominant protein expressed. polyclonal antisera demonstrate antigenic cross-reactivity among these proteins but suggest differences in epitopes. monoclonal antibodies to the 97-kda s-layer protein of campylobacter fetus subsp. fetus strain 82-40lp showed three different reactivities. monoclonal antibody 1d1 re ...19937688715
protein shift and antigenic variation in the s-layer of campylobacter fetus subsp. venerealis during bovine infection accompanied by genomic rearrangement of sapa homologs.campylobacter fetus subsp. venerealis isolated from a case of human vaginosis was inoculated into the uterus of a c. fetus-negative heifer. isolates obtained weekly from the vaginal mucus exhibited variations in high-molecular-mass-protein profiles from that of the original inoculum, which had a dominant 110-kda s-layer protein. immunoblots of the weekly isolates with monoclonal antibody probes against the 110-kda s-layer protein and other c. fetus s-layer proteins demonstrated antigenic shifts. ...19957721688
interleukin-8 response of gastric epithelial cell lines to helicobacter pylori stimulation in vitro.gastric infection with helicobacter pylori activates a mucosal inflammatory response by mononuclear cells and neutrophils that includes expression of cytokines interleukin-1 beta (il-1 beta), il-6, tumor necrosis factor alpha, and il-8. in this study, we analyzed the il-8 response of human gastric cancer cell lines (kato iii, ags, and mkn28) to h. pylori infection in vitro. il-8 mrna expression was detected by reverse transcription-pcr amplification of rna extracted from epithelial cells after i ...19957729872
[campylobacter fetus subspecies fetus endoaortitis on a bentall tube prosthesis. apropos of a case].campylobacter fetus is a rare cause of endocarditis and endoaortitis: the authors believe this to be the second reported case of infection of an intracardiac prosthesis. the patient was a man who had already undergone replacement of the aortic valve and ascending aorta, and a gastrectomy, which were predisposing factors. the portal of entry was not found. the diagnosis was confirmed by positive blood cultures and transoesophageal echocardiography. the outcome was rapidly fatal despite antibiotic ...19947771897
segmental conservation of sapa sequences in type b campylobacter fetus cells.campylobacter fetus cells may exist as either of two defined serogroups (type a or b) based on their lipopolysaccharide (lps) composition. wild-type strains contain surface array proteins (s-layer proteins) that have partial antigenic cross-reactivity but bind exclusively to lps from homologous (type a or b) cells. type a cells possess 8 homologs of sapa, which encodes a 97-kda s-layer protein; the gene products of these homologs have a conserved n terminus of 184 amino acids. to further explore ...19957797493
good's syndrome with a block in the early stage of b cell differentiation and complicated by campylobacter fetus sepsis.a 63-year-old man was admitted for campylobacter fetus sepsis and immunodeficiency syndrome with thymoma (good's syndrome). serological examination demonstrated hypoimmunoglobulinemia. analysis of lymphocyte subsets in the peripheral blood and bone marrow showed marked decreases in the proportion of cells bearing b cell markers. however, there were no abnormalities of cellular immunity. this is a rare case of good's syndrome in japan in which the pathogenic mechanism involved a block in the earl ...19947803919

[campylobacter fetus, an infrequent microbe, as a cause of spontaneous bacterial peritonitis in cirrhosis].campylobacter fetus has been implicated in the etiology of sepsis and bacteriemias in immunosupressed subjects. in a few cases, it has also been reported to be responsible for spontaneous bacterial peritonitis in cirrhotic patients. we describe the clinical picture of a woman with terminal liver cirrhosis who had bacteriemia and spontaneous bacterial peritonitis caused by this agent. we argue about the history of cleansing enemas and their probable role in the development of the infection. we st ...19947848698
localization of the sapa gene on a physical map of campylobacter fetus chromosomal dna.we constructed a physical map of campylobacter fetus tk(+) chromosomal dna digested by either smai, sali, or noti using pulsed-field gel electrophoresis and southern hybridization data. the genome size of c. fetus tk(+) is 2016kb, larger than that reported by the others. to locate the sapa gene, which encodes the surface array protein (sap), on the physical map, we performed southern hybridizations with probes based on the conserved region of the sapa gene. the results showed that more than seve ...19947872836
high-frequency s-layer protein variation in campylobacter fetus revealed by sapa mutagenesis.campylobacter fetus utilizes paracrystalline surface (s-) layer proteins that confer complement resistance and that undergo antigenic variation to facilitate persistent mucosal colonization in ungulates. c. fetus possesses multiple homologues of sapa, each of which encode full-length s-layer proteins. disruption of sapa by a gene targeting method (insertion of kanamycin (km) resistance) caused the loss of c. fetus cells bearing full-length s-layer proteins and their replacement by cells bearing ...19947885229
a lipopolysaccharide-binding domain of the campylobacter fetus s-layer protein resides within the conserved n terminus of a family of silent and divergent homologs.campylobacter fetus cells can produce multiple s-layer proteins ranging from 97 to 149 kda, with a single form predominating in cultured cells. we have cloned, sequenced, and expressed in escherichia coli a sapa homolog, sapa2, which encodes a full-length 1,109-amino-acid (112-kda) s-layer protein. comparison with the two previously cloned sapa homologs has demonstrated two regions of identity, approximately 70 bp before the open reading frame (orf) and proceeding 550 bp into the orf and immedia ...19957896695
campylobacter fetus diarrhea in a hutterite colony: epidemiological observations and typing of the causative organism.following a case of campylobacter fetus sepsis and meningitis in a 4-month-old female member of a hutterite colony, an epidemiological investigation revealed at least 18 cases of diarrhea in other members of the colony. c. fetus was isolated from 7 of 15 fecal samples submitted from affected persons. a case control study suggested that persons who worked in the abattoir were 2.03 times more likely to have had diarrhea, but none of the risk factors studied were significant. the epicurve of the ou ...19947910829
[campylobacter fetus subsp. fetus in a patient with liver cirrhosis].campylobacter fetus subsp. fetus infections are very rare in adults but can occur in immunocompromised elderly people and in patients with chronic disease. we describe the clinical case of a 52-year-old woman with alcoholic liver cirrhosis, where we isolated c.fetus subsp. fetus from blood culture.19947927478
persistence of campylobacter fetus bacteremia associated with absence of opsonizing antibodies.campylobacter fetus causes systemic infections in immunocompromised hosts. we describe a case in which c. fetus bacteremia apparently relapsed after 7 years in a patient with hypogammaglobulinemia and characterize the serum resistance of the patient's c. fetus strain and the inability of the patient's serum, with and without commercial intravenous immunoglobulin, to opsonize this and another c. fetus strain effectively. the probable presence of a sequestered site of infection in bone, the intrin ...19947929763
