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
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
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
susceptibility of campylobacter fetus to twenty-two antimicrobial 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
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
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
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
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
[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
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
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
