improved medium for enumeration of clostridium perfringens.an improved selective medium, tryptose-sulfite-cycloserine (tsc) agar, for the enumeration of clostridium perfringens is described. it consists of the same basal medium as shahidi-ferguson-perfringens (sfp) agar, but with 400 mug of d-cycloserine per ml substituted for the kanamycin and polymyxin. tolerance of c. perfringens for d-cycloserine, its production of lecithinase, and its ability to reduce sulfite were used as the basis for development of this medium. comparisons were made between tsc ...19714331774
chemically defined medium for the growth of clostridium perfringens.a defined medium which supports growth of clostridium perfringens at low inoculum levels was developed. generation time for strain 8797 was 1.5 times greater than previously reported for growth in purged fluid thioglycolate medium.19714331776
clostridium perfringens. i. sporulation in a biphasic glucose-ion-exchange resin medium.a biphasic culture medium suitable for cultivation and sporulation of clostridium perfringens, c. botulinum, and c. sporogenes was devised. the medium designed for use in a disposable, compartmented, plastic film container contained peptones, yeast extract, minerals, an anion exchange resin, and glucose in 4% agar as the solid phase and (nh(4))(2)so(4) and 0.1% agar as the liquid phase. with the biphasic system, it was not necessary to use active cultures as inocula. growth was at least equal to ...19714332043
analysis of clostridium botulinum toxigenic types a, b, and e for fatty and carbohydrate content.lyophilized, 48-hr log-phase vegetative cells were extracted with chloroform-methanol (2:1, v/v) and ethanol-ether (3:1, v/v) and then saponified with methanolic koh. gas-liquid chromatography of the methyl esters of extractable fatty acids revealed distinctive "pattern profiles" of clostridium botulinum toxigenic types "a," "b," and "e." c. perfringens type "a" and escherichia coli strain "b" were also studied in a similar manner and were found to give pattern profiles which were distinct even ...19714324194
new quantitative, qualitative, and confirmatory media for rapid analysis of food for clostridium perfringens.a selective and differential medium, shahidi-ferguson perfringens agar (sfp agar), and a confirmatory medium, lactose-motility agar (lm agar), were developed for the enumeration and identification of clostridium perfringens in foods. these media provide a rapid, specific, and direct diagnosis of c. perfringens. sfp agar contains sodium metabisulfite and ferric ammonium citrate to demonstrate h(2)s production and egg yolk to demonstrate lecithinase production by c. perfringens. on sfp agar, c. pe ...19714324195

identification of isolates of clostridium perfringens types c and d by agglutination and fluorescent-antibody methods.agglutination and fluorescent-antibody methods were employed for screening clostridium perfringens types c and d from 393 isolates of this organism. all of 50 strains which were isolated in japan and were agglutinable with an antiserum prepared against a stock strain of type c no. 3182 toxigenically belonged to type c, but the antiserum showed no cross-agglutination with any of type c strains isolated in denmark. all of the latter strains, however, were agglutinated by an antiserum prepared agai ...19714324883
medium for toxin production by clostridium perfringens in continuous culture.a tryptone-salts medium for continuous growth and alpha toxin production of clostridium perfringens type a in an adapted chemostat is described. in such steady-state cultures, fermentative and biochemical activity of c. perfringens remained unchanged. toxigenic ability to produce alpha, theta, and nu toxins was preserved.19714324884
comparison of media for the enumeration of clostridium perfringens.for the enumeration of viable vegetative cells and spores of clostridium perfringens, noncommercial (laboratory prepared) sulfite-polymyxin-sulfadiazine (sps) agar, tryptone-sulfite-neomycin (tsn) agar, and shahidi-ferguson-perfringens (sfp) agar were statistically compared to sps agar without antibiotics. the selectivities of these four media were also evaluated on the basis of their ability to inhibit the growth of pure cultures of a variety of other organisms. the average recovery of vegetati ...19714324885

lecithin-agar assay for lecithinase antibodies in serum.a technique for assay of lecithinase antibodies in serum was developed in this laboratory by using a lecithin-agar plate diffusion procedure based on a combination of described plate assays. egg yolk lipoprotein composed primarily of lecithin was used as a substrate for reaction with free or non-neutralized lecithinase c after incubation of known amounts of lecithinase c with various dilutions of control and test sera. it was found that the size of the reaction zone was a function of enzyme conc ...19714322282

mechanism of action of the enteropathogenic factor of clostridium perfringens type a.cell extract of an enteropathogenic strain of clostridium perfringens type a was administered intravenously to lambs, rabbits, and guinea pigs. lambs developed transitory diarrhea, lacrimation, salivation, nasal discharge, lassitude, and dyspnea in 1 to 5 hr after inoculation. large doses of the inoculum caused rapid onset of the clinical signs and subsequent death. examination of dead animals revealed intensely hyperemic small intestinal mucosa and some congestion in the liver, lungs, spleen, a ...197116557924
clostridium perfringens type a food poisoning i. response of the rabbit ileum as an indication of enteropathogenicity of strains of clostridium perfringens in monkeys.diarrhea and vomiting have been experimentally produced in monkeys after oral challenge with viable cells or culture filtrates of certain strains of clostridium perfringens that previously had been shown to produce either fluid accumulation in the ligated ileum or overt diarrhea in the nonligated ileum of the rabbit, or both. strains (or their culture filtrates) which did not produce a response in the rabbit likewise produced no symptoms in monkeys.197116557936
clostridium perfringens type a food poisoning ii. response of the rabbit ileum as an indication of enteropathogenicity of strains of clostridium perfringens in human beings.the effect of feeding human beings individual strains of clostridium perfringens or culture filtrates thereof was examined. the strains selected for challenge included both those which had previously been shown to produce fluid accumulation in the ligated ileum or overt diarrhea when injected into the nonligated ileum of the rabbit, or had produced both, and those which did not regularly produce these responses. challenge doses prepared by allowing each strain to grow in beef stew for 3 hr at 46 ...197116557937
intestinal strangulation in clostridium perfringens-monocontaminated rats.ischemic and hemorrhagic strangulation of closed intestinal segments was studied in germ-free rats individually contaminated with one of seven separate strains of clostridium perfringens type a. the principal findings were that (i) the monocontaminated rats with ischemic or hemorrhagic intestinal strangulation died at the same rapid rate; (ii) intraintestinal blood did not augment the action of c. perfringens in the presence of ischemic strangulation; (iii) although some strains were more toxic ...197116557999

effect of intramuscular or intrahepatic injections of clostridium perfringens on rabbit serum lactate dehydrogenase.serum lactate dehydrogenase (ldh) activity, ldh isoenzyme pattern, phospholipase c activity, phosphorous level, hemoglobin, and erythrocyte osmotic fragility were followed in rabbits after intramuscular (im) or intrahepatic (ih) injections of clostridium perfringens. on the first day after im injection, there was a drop in ldh activity; this was followed by an increase of ldh activity on the third and sixth day. on the seventh day, ldh activity began to decline, and by the ninth day it had almos ...197016557808
