method for estimating the presence of clostridium perfringens in food.the methods currently used for the enumeration of clostridium perfringens in food are often inadequate because of the rapid loss of viability of this organism when the sample is frozen or refrigerated. a method for estimating the presence of c. perfringens in food which utilizes the hemolytic and lecithinase activities of alpha toxin was developed. the hemolytic activity was measured in hemolysin indicator plates. lecithinase activity of the extract was determined by the lecithovitellin test. of ...19704321712

polysaccharide from dry navy beans, phaseolus vulgaris: iits isolation and stimulation of clostridium perfringens.a microbiological assay is described for determining gas produced by clostridium perfringens (veilon and zuber) holland from materials believed to be flatulent. a rationale for its use is given and analyzed. the fractionation and the results of the assay for several components of lima beans, phaseolus lunatus l., and navy beans, p. vulgaris l., are given. in particular, a polysaccharide was isolated from dried p. vulgaris seeds. only about one-seventh as much could be isolated from green p. luna ...19704320862

oxidation-reduction potential and growth of clostridium perfringens and pseudomonas fluorescens.a new apparatus was developed for measuring changes in e(h), ph, and cell numbers. with this apparatus, the relationships of these parameters were studied at initial e(h) levels of 200 and 40 mv (ph 7.0), by using clostridium perfringens and pseudomonas fluorescens. one of the strains of c. perfringens grew more luxuriantly at the higher e(h), in the presence of small quantities of oxygen, than at the lower one in the absence of oxygen. p. fluorescens could grow at a relatively low e(h) (40 mv, ...19704320922

hydrolysis of conjugated bile acids by cell-free extracts from aerobic bacteria.by means of an aerobic enrichment culture technique, several bacteria that hydrolyze conjugated bile acids and modify the formed deconjugates were isolated from feces of man, rat, and chicken and from soil. hydrolase activity was intracellular and extractable, and the yield of the enzymes was increased by adding the conjugated bile acids to the culture media. the hydrolase from bacterium of human origin was stable, having a ph optimum at about 7.0. all bile acid conjugates were hydrolyzed linear ...19704314376
pathogenicity of clostridium perfringens for germ-free guinea pigs after oral ingestion.germ-free guinea pigs died with signs and lesions of acute enterotoxemia after oral ingestion of c. perfringens types b, c, d, and e. the signs and lesions observed resembled those seen in acute enterotoxemia of sheep and cattle and the naturally occurring disease seen in "ex-germ-free" guinea pigs. c. perfringens type a was found to be innocuous. conventional guinea pigs did not become ill after ingestion of any of the five toxigenic types.19704314377
growth from spores of clostridium perfringens in the presence of sodium nitrite.the method by which sodium nitrite may act to prevent germination or outgrowth, or both, of heat-injured spores in canned cured meats was investigated by using clostridium perfringens spores. four possible mechanisms were tested: (i) prevention of germination of the heat-injured spores, (ii) prior combination with a component in a complex medium to prevent germination of heat-injured spores, (iii) inhibition of outgrowth of heat-injured spores, and (iv) induction of germination (which would rend ...19704314380

unusual sphaerophorus species from the large intestine of man.an obligately anaerobic, gram-negative microorganism identified as a sphaerophorus species was recovered from the fecal material of two cancer (chronic myelogenous leukemia and idiopathic thrombocythemia) patients receiving cobalt radiation therapy. the organism, isolated on sheep blood-agar, exhibited extreme pleomorphism (rods, filaments, and spheroids) and was a major component of the anaerobic fecal microflora. in one patient the numbers of sphaerophorus species (designated as isolate 6-13-6 ...19704314840
evaluation of a new incubation-type indole strip test.a total of 189 of enterobacteriaceae and three strains of clostridium perfringens were tested with a new incubation-type indole paper strip. this 4-hr incubation test gave the same results as a standard 48-hr indole test, except with some strains of proteus rettgeri. results with p. rettgeri varied somewhat according to the medium upon which the organisms had been grown.19704314843

endo-n-acetyl-glucosaminidase from clostridium perfringens, lytic for cell wall murein of gram-negative bacteria.an endo-n-acetyl-glucosaminidase which degrades the murein (peptidoglycan) sacculi of the cell walls of escherichia coli and spirillum serpens, but not those of micrococcus lysodeikticus and sarcina lutea, is present as a contaminant in a "phospholipase c" from clostridium perfringens. the specificity of enzyme action was elucidated by reduction of liberated glycosidic groups with nabh(4) and identification of glucosaminol as the reduction product. this finding contradicts previous reports assoc ...19704315891

bacteriological examination of commercial precooked eastern-type turkey rolls.studies were conducted to ascertain the bacteriological condition of commercially cooked eastern-type (foil-wrapped-oven roasted) turkey rolls during processing and storage. after 2 weeks at 5 c, numbers of aerobes on the surface of rolls, in slices, and in whole rolls reached levels of from 1 to 10 million per cm(2) or per g. in stored whole rolls, coliform and enterococcus counts ranged, respectively, from about 10,000 to more than 1 million per g and from < 100 to more than 1 million per g. p ...19704316271

influence of water activity on the growth of clostridium perfringens.each of four strains of clostridium perfringens was grown in modified fluid thioglycolate medium which was adjusted to yield selected water activity (a(w)) levels. the adjustments to secure the desired a(w) levels were made with nacl, kcl, or glucose. at each a(w) level, further modification was effected to produce four ph values. cultures were incubated at either 37 or 46 c. the solute used to achieve the reduced a(w) levels appeared to have a definite effect on the magnitude of growth achieved ...19704318452

action of bacterial growth on the sarcoplasmic and urea-soluble proteins from muscle. i. effects of clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, streptococcus faecalis, and kurthia zopfi.comparisons of the starch-gel patterns of uninoculated aseptic control samples from rabbit and pig muscle with similar samples inoculated and incubated with clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, and kurthia zopfii were made. results indicated that c. perfringens caused extensive alteration in the proteins or enzymes, or both, of the sarcoplasmic fraction of porcine muscle, whereas s. enteritidis and s. faecalis caused complete breakdown of only myoglobin. n ...19704318570
characterization of clostridia by gas chromatography differentiation of species by trimethylsilyl derivatives of whole-cell hydrolysates.trimethylsilyl (tms) derivatives prepared from whole-cell hydrolysates of 36 strains, representing 10 species of clostridium were examined by gas-liquid chromatography (glc). the tms profile of each species contained a group of peaks which characterized the species. variation among strains within a species was much lower than variation between species. some of the closely related clostridia could be differentiated by comparing their tms profiles. strains of clostridium botulinum were distinguish ...19704318575

effect of bile acid deconjugation on the fecal excretion of steroids.the effect of microbiological deconjugation of bile acids on total bile acid and neutral sterol fecal excretion by adult male rats has been studied. a screening method utilizing mice allowed selection of a clostridium perfringens type a strain, which accelerated cholesterol catabolism in mice. when this species of bacteria was associated with germfree rats, the fecal bile acids were excreted as free bile acids (deconjugated), however the quantities of bile acids excreted were not increased compa ...19704318910
