| germination of heat- and alkali-altered spores of clostridium perfringens type a by lysozyme and an initiation protein. | the normal system functioning in the utilization of metabolizable germinants by both heat-sensitive and heat-resistant spores of clostridium perfringens was inactivated by heat or by treatment of the spores with alkali to remove a soluble coat protein layer. altered spores were incapable of germination (less than 1%) and outgrowth (less than 0.0005%) in complex media without the addition of either lysozyme or an initiation protein produced by c. perfringens. the addition of either of these agent ... | 1972 | 4333607 |
| use of dogs as an assay for clostridium perfringens enterotoxin. | three techniques for using the dog as an assay organism for clostridium perfringens enterotoxin are described. these are believed to be more convenient than ligated ileal-loop procedures. | 1972 | 4333896 |

| sialic acids on the plasma membrane of cultured human lymphoid cells. chemical aspects and biosynthesis. | from 61 to 92% of the total sialic acid of a variety of human lymphoid cell lines maintained in tissue culture is present on the cell surface as measured by its susceptibility to cleavage by clostridium perfringens neuraminidase. these cells contain from 1.22 x 10(8) to 6.99 x 10(8) molecules of surface sialic acid per cell. in synchronized cultures synthesis of surface sialic acid occurs only during a limited time in the late g(2) phase of the cell cycle. the amount and density of surface siali ... | 1972 | 4502785 |
| hyperbaric oxygen exposures at 3 and 4 atmospheres absolute pressure for experimental gas gangrene: succinate protection against oxygen toxicity. | the concurrent effect of succinate administration to protect against oxygen toxicity and of hyperbaric oxygen (hbo) exposures to treat model gas gangrene in mice was tested to determine whether succinate would interfere with the therapeutic efficacy of hbo. hbo (seven 90-min exposures) at 3 atmospheres absolute pressure (ata) had been shown to reduce significantly the mortality of mice injected with clostridium perfringens suspended in 10 mug of adrenalin. when succinate was tested with this sys ... | 1972 | 4670508 |

| assessment of the sanitary effectiveness of holding temperatures on beef cooked at low temperature. | beef cubes cooked at low temperature were surface inoculated and incubated at 43.3 through 53.3 c to establish temperature limits for growth of staphylococci, salmonellae, and clostridium perfringens. a greater than 99% reduction in staphylococci was achieved after 6 hr at 48.8 c, of salmonellae at 51.1 c, and of c. perfringens at 53.3 c. there were no survivors of a mixed inoculum of staphylococcus aureus, salmonella enteritidis, and c. perfringens after 12 hr at 51.1 c. | 1972 | 4343865 |

| immunochemistry of the capsular polysaccharides from clostridium perfringens: selected hobbs strains 1, 5, 9, and 10. | the properties of the immunochemically distinct substances isolated from four strains of clostridium perfringens, mucoid variants of hobbs 1, 5, 9, and 10, were shown to be compatible with the hypothesis that polysaccharides are generally responsible for the "type-specificity" of these organisms. the presence of "group-specific" substance was demonstrated by the cross-reaction of recent preparations of hobbs 5 antisera with the isolated polysaccharides. the cross-reactions were not observed with ... | 1972 | 4343932 |

| purification and biochemical properties of clostridium perfringens type a enterotoxin. | the sporulation-specific enterotoxin of clostridium perfringens type a, which is the toxin active in human food poisoning, has been purified from extracts of sporulating cells. highly purified enterotoxin was obtained by treatment of crude cell extract with ribonuclease for 30 min, followed by sequential chromatography on sephadex g-100, cellex t cellulose, and hydroxylapatite. recovery was 65 to 75% of the initial activity. enterotoxin purity was > 99% as indicated by sedimentation velocity, se ... | 1972 | 4344364 |

| chemically defined medium for growth and sporulation of clostridium perfringens. | a chemically defined medium was developed that could support sporulation and growth of clostridium perfringens strains atcc 12916 and h9. this medium consisted of a modification of the basal medium of boyd et al. plus 0.1% sodium thioglycolate and 0.5% monosodium glutamate. five other strains grew, but did not sporulate, in this medium. with the addition of more vatamins into the medium, two more strains grew but did not sporulate. the effects of glucose, monosodium glutamate, ammonium glutamate ... | 1972 | 4344959 |
| quantitation of clostridium perfringens type a enterotoxin by electroimmunodiffusion. | conditions for quantitation of clostridium perfringens type a enterotoxin by electroimmunodiffusion are described. as little as 0.01 mug of enterotoxin could be detected. electroimmunodiffusion was more sensitive than either single gel diffusion or quantitation based on erythemal activity of the toxin in guinea pig skin. | 1972 | 4344960 |

| bile acids: a ph dependent antibacterial system in the gut? | bile acids are secreted in the bile in the form of conjugates and many species of intestinal bacteria can rapidly deconjugate them. studies have shown that an unconjugated bile acid may have bactericidal and bacteriostatic effects, which are ph dependent. it is proposed that unconjugated bile acids may be involved in a homoeostatic mechanism, preventing bacterial growth in the small intestine. | 1972 | 4342502 |
