gram-negative endocarditis caused by campylobacter fetus.campylobacter fetus is a rare cause of endocarditis that is difficult to diagnose because of the fastidiousness of the organism. the source of infection is unknown and it may involve a normal or previously damaged aortic valve. the onset is insidious, and if there is a prior history of recent onset of fever, thrombophlebitis, and diarrhea, infection caused by this organism should be considered. echocardiography may be useful. the organism is sensitive to a variety of antibiotics, including the c ...1978705408
campylobacteriosis in man: pathogenic mechanisms and review of 91 bloodstream infections.five patients with campylobacter fetus(previously called "vibrio fetus") bacteremia are presented with enteric symptoms in four patients, a self-limited course in three, and with possible nosocomial infection in one patient who had disseminated malignancy. the clinical syndromes of 91 bacteremic patients with campylobacteriosis and c. fetus taxonomy and pathogenicity are reviewed. studies of potential pathogenic mechanisms in enteric infections failed to reveal the production of either heat-stab ...1978707518
effect of interval between booster vaccination and time of breeding on protection against campylobacteriosis (vibriosis) in cattle.thirteen heifers (group a) given a booster vaccination with campylobacter fetus 4 1/2 months before breeding to bulls infected with the homologous strain had a pregnancy rate of 54%, compared with a pregnancy rate of 92% for 12 heifers (group b) given a booster vaccination 10 days before the 63-day breeding period began. none of 7 nonvaccinated heifers became pregnant, and all remained infected for at least 136 days. all three groups of heifers were bred by the same infected bulls. nine of the h ...1978711587
evaluation of a transport medium for campylobacter (vibrio) fetus.a quantitative assessment was performed on a serum enrichment medium for campylobacter (vibrio) fetus, to test its effectiveness as a transport medium. abundant yields of c fetus were obtained with an inoculum size of 10(4), even after keeping the medium in air at 22 to 23 c for 4 days prior to incubation at 37 c under microaerophilic conditions. the organism could be isolated from the medium kept in air at 22 to 23 c for at least 2 days, with an inoculum as small as 100 organisms. it was conclu ...1978711588

campylobacter enteritis associated with canine infection.campylobacter fetus ss. jejuni has recently been recognised as a human enteric pathogen. five cases of campylobacter enteritis are described. all five patients had abdominal pain and diarrhoea. two of the five patients had bloody diarrhoea and relapses. all the patients had been in contact with young dogs which had had diarrhoea. campylobacter fetus ss. jejuni was isolated from these dogs or from their litter-mates. canine infection with campylobacter fetus ss. jejuni may be an important source ...197882001
[diagnosis of vibriosis in bulls at breeding stations through lavages of the artificial vagina].the objective of the study was to test the suitability of lavages of artificial vaginas which are used for collecting ejaculate for diagnosing the campylobacter fetus subsp. fetus germs. according to the results of the investigation this method may be considered equal to the method of lavages of the prepuce. however, it is important to point out the advantages: it eliminates the danger of an accident, it enables quality lavage in the laboratory. to caputure the campylobacter fetus the filtration ...197896573
influence of seminal additives and packaging systems on fertility of frozen bovine spermatozoa.the following recommendations and conclusions are based upon results of fertility and laboratory studies, and general trends from field investigations. fertility results due to the addition of enzymes have been variable and contradictory. flushing of ampules with dry, gaseous nitrogen prior to filling has become a routine practice in processing semen to be frozen. for control of vibrio fetus and leptospira pomona, 2,000 micrograms of streptomycin and 1,000 u polymyxin b sulfate should be added p ...1978162535
susceptibility of campylobacter fetus to twenty-two antimicrobial agents.in vitro susceptibility of 11 recent clinical isolates of campylobacter fetus to 22 antimicrobial agents was determined by an agar dilution technique. unlike most obligate anaerobic gram-negative bacilli, c. fetus isolates tested were relatively resistant to penicillin and cephalosporins, but exquisitely susceptible to tetracyclines and aminoglycosides. all strains were also inhibited at concentrations achievable in serum by clindamycin, chloramphenicol, metronidazole, carbenicillin, ticarcillin ...1978263884
isolation of campylobacter fetus from recent cases of human vibriosis.campylobacter fetus was isolated from five recent cases of human vibriosis, of which two were adults and three were children. one adult presented with pericarditis and the other with recurrent pyrexia. campylobacter fetus subsp. intestinalis which resembled cattle strains serologically, was isolated under co2 or anaerobic conditions from blood cultures of these patients. two of the three children had kwashiorkor and the third was only 8 days old. isolates identified as campylobacter fetus subsp. ...1977270524
blastogenic transformation by lipopolysaccharide of blood leukocytes from immunized but not normal cattle.escherichia coli lipopolysaccharide produced blastogenic transformation in whole-blood leukocytes from heifers that had been infected and immunized with campylobacter fetus, but not in cells from control animals. this suggests that lipopolysaccharide dose not function as a b-cell mitogen in cattle and that its stimulation of cells from immunized animals occurred through another mechanism.1977330414
the isolation and nature of campylobacters (microaerophilic vibrios) from laboratory and wild rodents.faeces voided by eight species of laboratory or feral rodents were cultured for campylobacters by means of selective methods. campylobacters were isolated from bank voles and from rats, but not from rabbits, laboratory mice, hamsters, guinea-pigs, field mice or field voles. in routine biochemical tests isolates from bank voles resembled a type of campylobacter fetus that causes infectious infertility in cattle; isolates from rats resembled campylobacter coli associated with swine dysentery. elec ...1977330861
the effect of the nitroimidazole drug dimetridazole on microaerophilic campylobacters.dimetridazole, a nitroimidazole drug reported to act only on obligately anaerobic micro-organisms, is widely used for the prevention and treatment of swine dysentery. forty-four strains of the microaerophilic bacterium campylobacter coli isolated from either healthy or diseased pigs, and a strain of campylobacter fetus, were all sensitive to dimetridazole. the sensitivities (minimal inhibitory concentration less than 10 microng per ml) were similar to those of anaerobic bacteria. dimetridazole i ...1977558335
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 ...1977830489

a dual vaccine for the immunisation of cattle against vibriosis.single subcutaneous injections of a mineral oil adjuvant vaccine containing 20 mg dry weight of campylobacter fetus subsp fetus biotype venerealis cells and 20 mg dry weight of c. fetus subsp fetus biotype intermedius cells per 5 mil dose protected 2- and 3-year-old heifers and 3- and 4-year-old cows against genital infection with either organism.1977612316
comparison of three sampling methods for the diagnosis of genital vibriosis in the bull.three different methods of collecting preputial material for bacteriological examination were compared using 3 bulls infected with campylobacter fetus subsp. fetus. the first method utilised a specially designed instrument to scrape the preputial and penile mucosa, int he second method plastic pipettes were used to aspirate material and the third method involved washing the preputial cavity with sterile peptone water. bacteriological examination of the samples showed conclusively that scraping w ...1977612318
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.1976780182
[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 ...1976790309
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 ...1976819374
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 ...1976819375
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 ...19761259230
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 ...19761267237
[biochemical and serological investigations of flagellae of campylobacter fetus (author's transl)].flagellae of campylobacter fetus group o, types 1, 2 and 7 were prepared. first they were separated from cell bodies using an ultramix. the suspension was then centrifuged for 20 mins. at 10000 rpm and the supernatant frozen at -40 degrees c. this is a simple method for the enrichment of preparations of flagellae, as they become tangled up and accumulate in the inferior third part of the frozen liquid. the physicochemical basis of this phenomenon was discussed. after thawing and spinning for 20 ...1976936824

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.19761000394
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.19761015513
[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 ...19751041142
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 ...19751041482
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 ...19751112614
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 ...19751119063

effects of mycoplasma spp, trichomonas fetus, and campylobacter fetus on ciliary activity of bovine uterine tube organ cultures.microscopic observations were made of sections of normal bovine uterine tube (oviduct) and fimbriae maintained in vitro and exposed to agents known to localize in the bovine genital tract, i.e., mycoplasma, trichomonas fetus, and campylobacter fetus (vibrio fetus). only c fetus stopped ciliary activity. scanning electron microscopy (sem) revealed loss of most cilia. sterile filtrate of c fetus culture had no effect.19751155827
perinatal lamb mortality in western australia: 5. vibrionic infection.vibrionic abortion was diagnosed in sheep on 48 occasions between 1963-65 and 3 of these were associated with other major abortion pathogens. the outbreaks were scattered throughout the agricultural area of western australia. time-of-death of 91 infected lambs was: ante-parturient death 50.5%, parturient death 13.2% and post-parturient death 36.3% (deaths occurring immediately after death 28.6%, deaths delayed after death 2.2%, and late post-parturient death 5.5%). the majority of lambs had gros ...19751164266
the influence of age on the susceptibility of bulls to campylobacter fetus subsp venerealis.observations were carried out on 22 hereford bulls to determine the age at which they bacame carriers of c. fetus. during preliminary investigations, 5 bulbs were repeatedly exposed to the organism by artificial or natural means from the age of 18 months. all animals became longterm carriers on reaching an age of between 40 and 70 months. prior to this, a temporary carrier state lasting from 4 to 29 days was produced in 4 bulls. in a subsequent experiment, 17 bulls of 3 different age groups were ...19751167135
bovine venereal vibriosis: activity of inflammatory cells in protective immunity.the capability of bovine polymorphonuclear (pmn) and mononuclear phagocytes to kill campylobacter (vibrio) fetus venerealis was tested under various conditions in order to judge their roles in protective immunity. bovine pmn killed c fetus in the presence of immunoglobulin g (igg) but not immunoglobulin a (iga) antibodies. some phagocytosis occurred in the absence of antibody in glass-adherent cultures, but not in suspension cultures--indicating that surface phagocytosis by the neutrophils norma ...19751173209
immunisation of cattle against vibriosis with vaccines prepared from campylobacter fetus subsp fetus.subcutaneous administration of vaccines prepared from cells of campylobacter fetus subsp fetus strain a28 to heifers gave substantial protection against infertility due to c. fetus subsp venerealis strain b6. strains a28 and b6 had different heat-stable antigens and conformed respectively to serotype b and serotype a of berg et al (1971). the results suggested that the protective antigens were heat-labile antigens common to both strains. although vaccines prepared from serotype b strains of c. f ...19751180771

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.19751243730
gram-negative bacillary endocarditis. interpretation of the serum bactericial test.although the serum bactericidal test is commonly used in the management of infective endocarditis, little has been written about its validity or limitations. we report three cases of gram-negative bacillary endocarditis (pseudomonas aeruginosa, vibrio fetus and serratia marcescens) encountered in 1 year at a veterans administration hospital. serum bactericidal titers were considered necessary to identify inadequate antibiotic regimens or to avoid unnecessary drug toxicity. the limitations of the ...1975234679
superficial antigens of campylobacter (vibrio) fetus: characterization of antiphagocytic component.a glycoprotein responsible for the antiphagocytic properties of campylobacter fetus has been identified by comparing cells of a wild-type strain with those of a mutant lacking this substance. the antiphagocytic component is demonstrable through electron microscopy as a discrete, negatively charged structure on the periphery of the cell. clt is readily removed from the cell by mild extraction procedures and contributes to the inagglutinability in o antiserum normally displayed by c. fetus. cells ...197546843
[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.1975766378
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 ...1975804471
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 ...1975805241
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 ...1975809028

bovine venereal vibriosis: variations in immunoglobulin class of antibodies in genital secretions and serum.the immunoglobulin classes of antibodies to campylobacter (vibrio) fetus in cervicovaginal mucus (cvm) were determined by the indirect fluorescent antibody test at sequential periods, since the order of class appearance has not been established for specific secretory immune responses. in the local immune response to c. fetus immunoglobulin m (igm) antibodies appeared first, immunoglobulin a (iga) antibodies next, and immunoglobulin g (igg) last. igm antibodies were quite transient, but igg antib ...197416558094

lytic activity of vibrio phages on strains of vibrio fetus isolated from man and animals.five phages isolated from lysogenic strains of vibrio fetus var. venerealis and two from v. fetus var. intestinalis were tested for lytic activity on 95 v. fetus strains from various animal and human hosts. in addition, virion and plaque morphology of the seven phages were compared. electron micrographs showed that all were the kite-tailed variety with minor variations in head and tail dimensions. plaques of v45 and v2 were small, clear and irregular; those of v3, v8, and v19 were large, clear a ...19734201644

vibrio fetus infection in man: a serological test.antigen preparations derived from a typical human strain of vibrio fetus were employed in four tests. of these, the indirect bacterial hemagglutination test proved most sensitive. by this test, antibodies titering 320 to 3,200 were found in five of eight patients with confirmed infections. two patients without antibodies were on antimetabolites. antigenic relationship with other compounds, and in particular with brucella organisms, was not observed. no sero-reactors were found among 184 apparent ...19724673792
natural and immune antibodies for vibrio fetus in serum and secretions of cattle.naturally occurring antibodies for vibrio fetus with whole-cell and o antigen specificities were detected in sera of mature cattle by means of the agglutination and indirect immunofluorescence reactions. o antibodies occurred in each of 21 sera examined, and whole-cell antibodies, in lower concentrations, occurred in 15 of the 21 sera. natural antibodies were detected in the immunoglobulin g, m, and a (igg, igm, iga) classes. parenteral immunization with whole cells in freund's complete adjuvant ...19724564880
