| location of bacterial polysaccharide during various phases of growth. | polysaccharide-containing material was located by histochemical staining on ultrathin sections of bacillus cereus and several clostridial species during various phases of growth. these components were located along the cell wall in young vegetative cells and along the developing cortex in sporulating cells. in b. cereus any carbohydrate-containing material present along the forespore membrane was too small to be detected by direct staining. however, in three clostridial species such material was ... | 1969 | 4182530 |

| direct enzymatic repair of deoxyribonucleic acid single-strand breaks in dormant spores. | with the alkaline sucrose gradient centrifugation method, it was found that dormant spores of clostridium botulinum subjected to 300 krads of gamma radiation showed a distinct decrease in deoxyribonucleic acid (dna) fragment size, indicating induction of single-strand breaks (ssb). a two- to threefold difference in radiation resistance of spores of two strains of c. botulinum, 33a (37% survival dose [d(37)] = 110 krads) and 51b (d(37) = 47 krads), was accompanied by relatively larger dna fragmen ... | 1974 | 4206867 |

| rapid detection of clostridium botulinum toxin by capillary tube diffusion. | a micro capillary agar-gel diffusion system for the detection of botulinal toxin in foods and cultures was developed and evaluated. toxins types a, b, and e, produced in culture broth with and without added trypsin, and type e toxin, produced in inoculated canned clams, were tested with this system and with the mouse bioassay procedure. with nontrypsinized toxin, the capillary diffusion system detected as little as 100 minimal lethal doses (mld) per ml but was effective only at higher levels, 10 ... | 1974 | 4208636 |

| antigen and antibody in aleutian disease in mink. ii. the reaction of antibody with the aleutian disease agent using immunodiffusion and immunoelectroosmophoresis. | aleutian disease viral (adv) antigen was prepared by fluorocarbon extraction of spleen, liver, and lymph nodes from mink experimentally infected ten days previously. using a potent adv antigen, antibody was detected by immunodiffusion (id) and immunoelectroosmophoresis (ieop). utilizing these precipitin tests, antibody was detected in all the mink sera tested as early as seven days after experimental infection. titer of antibody increased throughout the infection period. titers of more than 100 ... | 1973 | 4270428 |

| antagonistic effect on clostridium botulinum type e by organisms resembling it. | a bacteriocin-like substance, active against strains of clostridium botulinum type e, is produced by certain nontoxic organisms whose biochemical properties and morphological characteristics are similar to type e. the substance, for which the name "boticin e" is proposed, is bacteriolytic for vegetative cells and bacteriostatic for spores of type e. its spectrum of activity is somewhat strain-specific. of the clostridial species tested, only c. botulinum type e and, to a lesser extent, c. perfri ... | 1966 | 4288828 |
| agar concentration in counting clostridium colonies. | decreasing the agar concentration of a counting medium from the usual 1.5% resulted in larger colonies with less interference from gas in clostridium botulinum 115b and c. sporogenes pa 3679. optimal agar concentration was 0.65% for c. botulinum with 24-hr incubation and 0.50% for c. sporogenes with 48-hr incubation. lower concentrations yielded growth too diffuse for counting. motility was considered the explanation for increased colony size in softer agar. the greater the degree of motility, t ... | 1967 | 4291671 |

| proline as an intermediate in the reductive deamination of ornithine to delta-aminovaleric acid. | fresh extracts of cells of clostridium botulinum reduced a limited amount of ornithine to delta-aminovaleric acid, but at high substrate concentrations a considerable amount of an amino compound accumulated which was neutral at ph 4.2. aging of the extracts at -10 c or freezing and thawing resulted in the loss of the ability to produce delta-aminovaleric acid, but the ability to produce the neutral compound was retained. this compound was separated by column chromatography, and was found to be i ... | 1968 | 4301045 |
| collagenolytic activity of bacteria. | actively growing aerobic and anaerobic bacteria were screened by a plate assay, with reconstituted guinea pig collagen as a substrate, for their ability to produce a collagenolytic factor. collagenolytic activity was not demonstrated among the aerobic organisms tested, with the exception of one strain of staphylococcus aureus (only when grown under anaerobic conditions). collagenolytic activity, however, was detected in cultures of clostridium tetani and bacteroides species other than b. melanin ... | 1969 | 4306539 |

| inhibition of protease production of various bacteria by ammonium salts: its effect on toxin production and virulence. | production of protease by many bacteria was found to be inhibited by ammonium salts, and the enzyme production was more sensitive to the salts than was growth of the organisms. inhibition of protease production by some pathogenic bacteria may result in the recognition of an exotoxin which otherwise would have been digested by the protease. in the case of pseudomonas aeruginosa, qualitatively different toxicities could be demonstrated in the culture fluids, depending on the presence or absence of ... | 1969 | 4309097 |

| fine structure of protoplasts and l-forms of clostridium botulinum types a and e. | spherical bodies, that are obtained by adding penicillin and lysozyme to clostridium botulinum types e and a cultures which are growing in an osmotically stabilized medium, are shown to be protoplasts by electron microscopy. the l-forms of these two culture types have morphologically different inclusion bodies. | 1971 | 4323294 |

| activation of a toxic component of clostridium botulinum types c and d by trypsin. | when the stockholm and 468c strains of type c and the 1873 strain of type d clostridium botulinum are "cured" of their prophages, they simultaneously discontinue the production of their dominant toxins (c(1) and d), but they continue to produce a second antigenically monospecific toxin (c(2)). these "cured" strains of types c and d therefore become indistinguishable with respect to the toxin produced. fifteen type c cultures received from other laboratories discontinued to produce the dominant t ... | 1972 | 4560464 |
