bovine veneral vibriosis: antigenic variation of the bacterium during infection.host parasite relationships in the female genital tract were studied in bovine venereal vibriosis by investigating agglutinin production and alterations in superficial antigens of the bacterium during the course of infection in two heifers. cervicovaginal mucus (cvm) steamed cell agglutinins were shown to appear earlier and remain at consistently higher levels than whole-cell agglutinins. whole-cell agglutinin titers fluctuated much more than steamed cell titers, suggesting possible changes in w ...197546214
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
haemophilus somnus complex: antigenicity and specificity of fractions of haemophilus somnus.five haemophilus somnus type 8025 preparations (whole cell, sonicate, crude polysaccharide, purified polysaccharide, and protein) were produced for studies of their antigenicity in rabbits. bacterial agglutination and passive hemagglutination tests were used to assess the level of antibody produced in rabbits inoculated with the different antigenic preparations. cross-reactions were seen between the antiserums against the h sumnus 8025 antigens and a variety of related and unrelated bovine patho ...197550755

[human campylobacteriosis. apropos of 6 cases].campylobacteriosis, first described as a disease of cattle where it is very common and causes sterility or abortion, appears to occur in man mainly in predisposed subjects with debility or some constitutional defect. the nature of the background should make one consider campylobacter as pathogenic. antibiotic treatment is necessary in all cases in order to avoid decompensation of the congenital disease. it is probable that campylobacter infections are more common than the small number of reporte ...1977190686
incomplete anaerobiosis as a cause of metronidazole 'resistance'.clostridium welchii, used as a control, was found to grow well in a microaerophilic jar used for campylobacters but appeared resistant to a metronidazole disc although the campylobacter was sensitive. minimum inhibitory concentrations for six strains of cl. welchii were up to 64-fold higher in these conditions than when grown anaerobically. zones of inhibition with both cl. welchii and bacteroides fragilis varied with the amount of air admitted to anaerobic jars.1978213449
superoxide dismutase and hydrogen peroxide formation in campylobacter sputorum subspecies bubulus.cell-free extracts of campylobacter sputorum subspecies bubulus contained superoxide dismutase. the enzyme was located in the cytoplasmic fraction and insensitive to cyanide. after centrifuging a cell-free extract at 144000 x g for 1.5 h the total activity in the supernatant fraction was threefold higher than in the crude cell-free extract. the pellet fraction thus obtained was shown to have a lowering effect on superoxide dismutase activities from different sources in the assay method used here ...1978214049
[infectious causes of perinatal mortalities in ruminants (author's transl)].the advantages and disadvantages of the different diagnostic techniques e.g. pathological and microbiological studies, immunoglobulin and specific antibody determinations and fluorescent antibody studies in relation to these mortalities are discussed. the most important pathological lesions in the placentas and foetuses are described.1978215769
studies of the microaerophilic nature of campylobacter fetus subsp. jejuni. ii. role of exogenous superoxide anions and hydrogen peroxide.the addition of bovine superoxide dismutase to brucella broth or brucellar agar greatly echanced the oxygen tolerance of campylobacter fetus subsp. jejuni strain h840 (atcc 29428). catalase also enhanced oxygen tolerance, but to a lesser extent. these enzymes must act externally to the bacteria. all of the diverse compounds which enhance oxygen tolerance of c. fetus, including nor-epinephrine and a combination of ferrous sulfate, sodium metabisulfite, and sodium pyruvate, share the ability to qu ...1979218715
etiology of infantile enteritis in south africa.infantile enteritis constitutes a major health problem in developing countries. several investigations into the etiology of this condition among various south african populations have been undertaken during the past few years. recent studies of black urban infants have revealed that salmonellae, shigellae, enterotoxigenic enterobacteriaceae, and rotaviruses play a relatively minor role in infantile enteritis. on the other hand, all studies, including a number performed several years ago, have de ...1979221438

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
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
microbiota of gingivitis in man.a study on the predominant cultivable microorganisms inhabiting gingival crevices affected with a chronic gingivitis was carried out using the roll tube culture technique. samples were obtained from nine individuals 25--42 years of age. gram-positive rods make up 29.1% of the isolates and included mainly actinomyces naeslundii, actinomyces israelii, and actinomyces viscosus. streptococcus mitis and streptococcus sanguis together made up 26.8% of the cultivable organisms. peptostreptococcus avera ...1978276916

pathology of proliferative haemorrhagic enteropathy in pigs.examination of the small intestine of pigs with proliferative haemorrhagic enteropathy showed changes consistent with defects in vascular permeability. early in the disease there were many eosinophils and distension of lacteals and intercellular spaces with proteinaceous material. later the predominant features were red blood cells and exudate in tissue spaces. this was most severe and extensive at the tips of villi which were covered by a cast of cells and fibrinous exudate. adenomatous intesti ...1979313620
proliferative haemorrhagic enteropathy.this study indicates that viable campylobacter sputorum subsp mucosalis are not present or are present in small numbers in the mucosa of pigs dying of proliferative haemorrhagic enteropathy. the changes present in the mucosa are similar to those seen in pigs recovering from adenomatosis and the evidence obtained indicates that the intracellular organisms observed in this condition are indeed mucosalis. the presence of large amounts of iga in the altered tissue of both proliferative haemorrhagic ...1979315603

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
