rearing of germfree and monocontaminated chicks in rigid plastic isolators.a plexiglas isolator for rearing germfree vertebrates is described. plastic components were precut and finished by a plexiglas supplier. this equipment is relatively inexpensive; moreover, neither special facilities nor skills are required in their construction. advantages of this type of isolator are: readily dismantled for cleaning, durable, excellent visibility of the interior, and minimal maintenance. in 30 separate groups of animals, 27 of these yielded germfree chicks. many of these chicks ...196214486221

the relationship of toxic fractions of a filtrate of clostridium perfringens type a to the pathogenesis of clostridial myonecrosis.a crude filtrate from a culture of clostridium perfringens, type a, was fractionated by a heavy metal-alcohol technique, and some degree of concentration of biologically active factors was achieved. both the crude material and the fractions obtained were characterized in terms of their alpha toxin, theta toxin, hyaluronidase, and collagenase activities. the filtrate and fractions were tested for their effect on the peripheral circulation of the rat, using the epinephrine threshold technique. the ...195514367682

pouch method for the isolation and enumeration of clostridia.an anaerobic film-pouch method has been developed for the isolation and enumeration of clostridia. fabrication of the pouch is described. counts of spore suspensions of putrefactive anaerobe 3679 and of clostridium botulinum strains 41-b and 33-a in pouches were compared with those obtained by anaerobic-jar and agar-deep techniques. statistical analysis revealed a significant difference in favor of the pouch over the tube and anaerobic-jar methods. tests performed with c. welchii, both in spore ...196514325895
resistance of clostridium perfringens type a spores to gamma-radiation.the radiation resistance of the spores of a classical strain and of an atypical, heat-resistant strain of clostridium perfringens was determined. spores were produced in ellner's and in a trypticase broth medium. approximately 10(6) viable spores per milliliter were suspended in 0.06 m phosphate buffer and irradiated with gamma rays from cobalt-60; the survivors were counted in tryptone-yeast extract-agar by the prickett-tube technique. radiation d values for spores of the atypical strain in pho ...196514325887
clostridium perfringens in meat and meat products.a total of 262 specimens of meat and meat dishes were examined for the presence of clostridium perfringens. of this total, 161 were raw, unprocessed beef, veal, lamb, pork, or chicken; 101 were processed meats and meat dishes. c. perfringens was isolated from 113 (43.1%) of these specimens. the highest percentage of contamination (82%) was found in veal cuts, and the lowest (4.7%) in sliced sandwich meats and spreads. only 2 of the 113 isolates were shown to produce heat-resistant spores, which ...196514325274
