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
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 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
[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 ...19921302865
[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 ...19921319039
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 ...19921354478
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 ...19921393820
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 ...19921400961
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.19921442025
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 ...19921458698
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 ...19921461153
