| clinical evaluation of the efficacy of inoculating cattle with a vaccine containing tritrichomonas foetus. | to test the efficacy of a polyvalent tritrichomonas foetus vaccine, 130 nulliparous heifers were randomly assigned to either receive the test t foetus vaccine or to serve as nonvaccinated controls. the polyvalent test vaccine consisted of a campylobacter fetus/leptospira canicola-grippotyphosa-hardjo-icterohaemorrhagiae-pamona bacterine containing 5 x 10(7) killed t foetus/dose. the polyvalent control vaccine consisted of the aforementioned formulation without t foetus. heifers were administered ... | 1992 | 1466496 |
| structural studies of peptidoglycans in campylobacter species. | peptidoglycans (pg) from campylobacter coli, campylobacter jejuni, and campylobacter fetus were composed of muramic acid, glucosamine, alanine, glutamic acid, and diaminopimelic acid in a molar ratio of 1.1:1:1.7:1.1:09. thirty percent of the amino groups of diaminopimelic acid were involved in cross-linkages between peptides. during cultivation, c. coli and c. jejuni changed from a spiral to a coccoid form. in c. coli, we could isolate pg only from the spiral forms in yields of 0.8-1.2% by dry ... | 1992 | 1461153 |
| anti-enterobacteria antibodies in psoriatic arthritis. | the occurrence of certain antibacterial antibodies was studied in the sera of 22 healthy donors (hd) and 66 patients with different diseases. the cases investigated included 22 rheumatoid arthritis (ra), 22 non-arthritic-psoriasis (nap), and 22 psoriatic arthritis (pa) patients. a complement fixation test was used with yersinia enterocolitica 0:3 type (yec), yersinia pseudotuberculosis (ypt), campylobacter jejuni (cj), and campylobacter fetus (cf) antigens; the detection of anti-chlamydia tracho ... | 1992 | 1458698 |
| nosocomial meningitis due to campylobacter fetus subspecies fetus in a neonatal intensive care unit. | we experienced a nosocomial outbreak of campylobacter fetus subspecies fetus (c. fetus) meningitis in a neonatal intensive care unit. a cluster of three infants developed meningitis approximately 1-1.5 months after the index patient was admitted. two asymptomatic intestinal carriers of c. fetus were detected during the outbreak. our experience indicates that c. fetus can cause nosocomial meningitis in neonates, and asymptomatic carriers may play a role in the transmission of the organism. | 1992 | 1442025 |
| specific detection of campylobacter jejuni and campylobacter coli by using polymerase chain reaction. | development of a routine detection assay for campylobacter jejuni and campylobacter coli in clinical specimens was undertaken by using the polymerase chain reaction (pcr). an oligonucleotide primer pair from a conserved 5' region of the flaa gene of c. coli vc167 was used to amplify a 450-bp region by pcr. the primer pair specifically detected 4 strains of c. coli and 47 strains of c. jejuni; but it did not detect strains of campylobacter fetus, campylobacter lari, campylobacter upsaliensis, cam ... | 1992 | 1400961 |
| nucleotide sequence analysis of the gene encoding the caulobacter crescentus paracrystalline surface layer protein. | the entire nucleotide sequence of the rsaa gene, encoding the paracrystalline surface (s) layer protein (rsaa) of caulobacter crescentus cb15a, was determined. the rsaa gene encoded a protein of 1026 amino acids, with a predicted molecular weight of 98,132. protease cleavage of mature rsaa protein and amino acid sequencing of retrievable peptides yielded two peptides: one aligned with a region approximately two-thirds the way into the predicted amino acid sequence and the second peptide correspo ... | 1992 | 1393820 |
| differentiation of the subspecies of campylobacter fetus by genomic sizing. | campylobacter fetus subsp. fetus and c. fetus subsp. venerealis are currently differentiated by tolerance to glycine and by their epidemiology. analysis of c. fetus dna by pulsed-field gel electrophoresis, after digestion with the restriction endonucleases smai and sali, was used to differentiate between the subspecies. all strains presently identified as c. fetus subsp. fetus had a genomic size of 1.1 mb, whereas the majority of the c. fetus subsp. venerealis strains had a genomic size of 1.3 m ... | 1992 | 1354478 |
| [neonatal campylobacter fetus septicemia: a case secondary to maternal-fetal contamination]. | a favourable outcome of a severe cambylobacter fetus sepsis in a neonate is reported. the transmission was probably vertical. his mother experienced diarrhoea 15 days before birth. no infecting organism was isolated from maternal stools, but maternal antibody response was significant. such a perinatal infection with meningitis and septicemia is uncommon. bacteriological diagnosis requires an enriched medium and a long incubation. the diagnosis should be evoked in view of an anamnestic context, a ... | 1992 | 1319039 |
| [evaluation of antimicrobial drugs and atmospheres for the isolation of campylobacter fetus subspp. from the bovine genital tract]. | growth of 3 reference bovine c. fetus strains in media with and without antibiotics and bacteriostats active against the most common contaminant bacteria in the bovine genital tract was evaluated. in addition, 2 regional bovine c. fetus strains and 1 reference c. sputorum biovar bubulus strain were used in some experiments. reference strain c. fetus subsp. venerealis was completely inhibited by polymyxin (> or = 0.25 iu/ml) whereas the other c. fetus strains were not inhibited. in shepler's medi ... | 1992 | 1302865 |
| ovine campylobacterosis: preliminary studies of the efficacy of the in vitro serum bactericidal test as an assay for the potency of campylobacter (vibrio) fetus subsp intestinalis bacterins. | an in vitro serum bactericidal test was developed to assess the efficacy of campylobacter fetus bacterins. four experimental monovalent bacterins (either serotype c or a-2) and 2 commercial bivalent bacterins (a "suspect" and an "efficacious" bacterin) with aluminum hydroxide adjuvant were administered to sheep and rabbits from which antiserums were then prepared. the different vaccines were evaluated by comparing the in vitro bactericidal activity of the sheep and rabbit antiserums. results of ... | 1976 | 1267237 |
| cystine aminopeptidase activity (oxytocinase) in pregnant guinea pigs: normal and infected with campylobacter fetus. | the cystine aminopeptidase (cap) activity was determined in plasma from guinea pigs at various stages of gestation and in pregnant guinea pigs infected with campylobacter fetus subspecies intestinalis. the cap activity decreased with length of gestation, which is in contrast to the changes in activity in persons. infected guinea pigs near the time of abortion can be distinguished from normal guinea pigs on the basis of plasma cap activity, if the plasma samples are taken 1 to 2 days before abort ... | 1976 | 1259230 |
| studies on veneral transmission of campylobacter fetus by immunised bulls. | temporary contamination of the penis and prepuce with campylobacter fetus subsp. venerealis and campylobacter fetus subsp. venerealis biotype intermedius may occur when immunised bulls mate with infected heifers. however, 2 experiments showed that this contamination was not a significant cause of genital infection in susceptible heifers that subsequently mated with bulls. | 1975 | 1243730 |

| vaccination against vibrio (campylobacter) fetus infection in sheep in late pregnancy. | a single injection of vaccine containing disrupted formol-killed vibrio (campylobacter) fetus var intestinalis serotype v was shown to give good protection against abortion from an oral challenge of the same serotype administered simultaneously. protection was also afforded by vaccination at the time of the first abortion in sheep infected orally one month previously. these results suggest that vaccination subsequent to an abortion might be of value in preventing a proportion of further abortion ... | 1975 | 1119063 |
| bovine veneral vibriosis: cure of genital infection in females by systemic immunization. | cure of female cattle with venereal vibriosis by systemic immunization with killed campylobacter fetus cells in incomplete freund adjuvant was investigated. heifers infected in the cervicovaginal area with a cloned population of c. fetus venerealis were vaccinated subcutaneously 14 and 24 days thereafter with the infecting strain in incomplete freund adjuvant. six of eight vaccinated heifers were free of infection 25 to 48 days postinfection. one of the cured animals had an intercurrent infectio ... | 1975 | 1112614 |
| bilateral deep brachial vein thrombophlebitis due to vibrio fetus. | a patient had bilateral deep brachial vein thrombophlebitis in which vibrio fetus was recovered from six blood cultures of the six drawn. fever and phlebitis continued with treatment with intravenous doses of heparin and oxacillin but rapidly improved with treatment change of oxacillin to clindamycin. in vitro antibiotic disk susceptibility testing confirmed resistance to oxacillin and susceptibility to clindamycin. vibrio fetus infection is associated with the vascular endothelium in this and p ... | 1975 | 1041482 |
| [the bacteriological diagnosis of vibrio fetus infection in man (author's transl)]. | a synopsis of the present classification of vibrio fetus is given (tab. 1, 2). besides the presentation of the importance of these bacteria in veterinary medicine, 97 human infections have been published up to now. the geographic, age and sex distribution of these cases and the material out of which the pathogens were isolated is presented (tab. 3, 4). the clinical picture is summarized. for the culture of vibrio fetus liver broth as described by tarozzi incubated for at least 3-4 days was suita ... | 1975 | 1041142 |
| vibrio fetus endocarditis in a patient with systemic lupus erythematosus. | vibrio fetus endocarditis occurred in a patient with systemic lupus erythematosus receiving azathoprin and prednisone. blood cultures required 14 days to become positive. the fastidious growth requirement of this organism is reviewed because lack of appreciation of these may result in failure to make the diagnosis. this is the first reported case of vibrio fetus endocarditis occurring in the setting of a connective tissue disorder and immunosuppressive therapy. | 1976 | 1015513 |
| a simple technique for mass cultivation of campylobacter fetus. | studies using 86 media for maximum growth of campylobacter fetus for antigen production showed that a diphasic medium (solid base with liquid overlay) was most suitable. the solid base was double strength cystine heart agar. the liquid overlay was thioglycollate medium of brewer (135-c) without agar. this medium yielded maximum growth of c. fetus in six days with good motility, less clumping and less filament formation than all other media tried. | 1976 | 1000394 |

| campylobacter fetus associated with pulmonary abscess and empyema. | an unusual case of community-acquired necrotizing aspiration pneumonia with pulmonary abscess and empyema associated with campylobacter fetus (formerly vibrio fetus) in mixed culture is reported. this microaerophilic gram-negative curved bacillus has been increasingly associated with human disease. unlike most pathogens associated with community-acquired aspiration pneumonia, this organism is usually resistant to penicillin. infection associated with this organism is characteristically relapsing ... | 1977 | 830489 |
| antibody-mediated immobilization of campylobacter fetus: inhibition by a somatic antigen. | immobilization tests were conducted on a wild-type strain of campylobacter fetus subsp. intestinalis and on a mutant lacking an antiphagocytic cell surface component. highly effective immobilization of the mutant, both as single cells and clumps of cells, was produced with an antiserum containing antibodies specific for the flagellar hook and filament and for the o antigen. damage to flagellar hooks after reaction with this antiserum was observed only with cells of the mutant. single-cell immob ... | 1976 | 819375 |
| major outer membrane protein of campylobacter fetus: physical and immunological characterization. | the outer membrane proteins of campylobacter fetus have been isolated by extraction of cell envelopes both in triton x-100 and ethylenediaminetetraacetate (edta) and in sodium dodecyl sulfate (sds). each method yielded a major protein component, which migrated identically in sds-polyacrylamide gel electrophoresis (sds-page) and proved comparable in electrophoretic and molecular weight characteristics to the analagous protein from escherichia coli. in addition, the surface of sds-extracted c. fet ... | 1976 | 819374 |
| infections associated with ovine perinatal mortality in victoria. | the occurrence of infections associated with perinatal mortality was investigated. in 1970, carcasses from 94 flocks distributed throughout victoria were examined by microbiological and histopathological techniques. carcasses from 4 of the same flocks were similarly examined in 1971. widespread occurrence of listeria monocytogenes and campylobacter fetus was demonstrated with l. monocytogenes being recognised in 25% of the flocks examined. no other bacterial pathogens commonly associated with ov ... | 1975 | 809028 |
| in-vitro effect of edta-tris-lysozyme solutions on selected pathogenic bacteria. | the in-vitro effect of edta-tris-lysozyme solution on 16 pathogenic bacteria of medical or veterinary importance was determined. marked decreases in bacterial count occurred with pseudomonas aeruginosa, escherichia coli, moraxella osloensis and campylobacter fetus, and smaller decreses with salmonella typhimurium, shigella boydii, aeromonas hydrophila, proteus mirabilis, listeria monocytogenes and erysipelothrix insidiosa. the test solution had no effect on klebsiella ozaenae, brucella canis, co ... | 1975 | 805241 |
| flagellar ultrastructure and flagella-associated antigens of campylobacter fetus. | ultrastructural examinations of the flagellum of compylobacter (vibrio) fetus were performed throughout the growth cycle. filament diameters, exceeding 17.6 nm during the exponential phase, were substantially greater than those reported for unsheathed flagella of other genera with the exception of pseudomonas fluorescens. filament diameters increased during growth, reaching a mean width of 21.2 nm in middle to late stationary phase. internal flagellar structure, principally of the parallel lined ... | 1975 | 804471 |
| [isolation of campylobacter fetus in two herds of sheep in sweden (author's transl)]. | in two herds of sheep with numerous abortions campylobacter fetus subspecies intestinalis was isolated from fetuses, fetal membranes, and faecal specimens. in herd a, with good hygiene, 12 ewes out of 250 aborted. in herd b, with poor hygiene, 54 out of 171 ewes aborted and 14 of them died; for a further 9 ewes the lambs died postnatally. the clinical course in both herds shows that proper supervision and possibilities of prompt isolation of aborting ewes can substantially reduce the spread of i ... | 1976 | 790309 |
| spontaneous peritonitis of cirrhosis due to campylobacter fetus. | an unusual case of spontaneous peritonitis of cirrhosis associated with campylobacter fetus is reported. this microaerophilic gram-negative bacillus has been increasingly associated with human disease recently, particularly in patients with cirrhosis. the infection is characteristically relapsing in nature and requires protracted antimicrobial therapy. | 1976 | 780182 |
| [type differentiation of v. fetus and v. bubulus by using fluorescent antisera]. | obtained were type-specific fluorescent vibrionic antisera for the laboratory identification of vibrio fetus strains. they produced positive fluorescence only with the homologous strains, and did not react with the heterologous strains. this showed that the sera were strongly specific. their use is suggested for the differentiation typing of the vibrio strains. | 1975 | 766378 |
