response and specificity of antibodies for shigella flexneri: demonstration of type-specific factors in immunoglobulin g fraction of antiserum.considerable amounts of immunoglobulin g (igg) antibody appeared in hyperimmune rabbit serum at a late period during a course of immunization with several injections of shigella flexneri o antigens. high yields of igg antibody possessing homogenous specificity could be fractionated from crude gamma-globulin solution on a diethylaminoethyl-sephadex column with 0.02 m phosphate buffer (ph 6.6) containing 0.1 m nacl. specificities of igg antibodies for six serotypes of s. flexneri were demonstrated ...19695788700

polynucleotide sequence relationships among members of enterobacteriaceae.polynucleotide relationships were examined among many representatives of the enterobacteriaceae by means of agar, membrane filter, and hydroxyapatite procedures. the amount of deoxyribonucleic acid (dna) that reassociated was dependent, especially in interspecific reactions, on the annealing temperature. in only three cases: escherichia coli-shigella flexneri, salmonella typhimurium-s. typhi, and proteus mirabilis-p. vulgaris, was relative interspecific duplex formation 80% or higher. in most ca ...19694891264

translocation of mrna codons. ii. properties of an anti-translocase antibody.a purified preparation of translocase, one of several enzymes required for protein biosynthesis, has been used to prepare a specific anti-translocase antibody. this antibody provides an extremely useful tool not only for detecting the enzyme independent of its activity, but for inhibiting the translocase-mediated reaction and, thus, protein biosynthesis. though the antibody very rapidly inhibits elongation of the peptide chain, it fails to effect initiation, binding, or peptide bond formation, w ...19694895218

inhibition of shigella flexneri by the normal intestinal flora. ii. mechanisms of inhibition by coliform organisms.of 15 strains of coliform bacteria, all isolated from human feces, 14 inhibited the growth of shigella flexneri in mixed culture. in every case, when inhibition occurred, exponential growth of shigella was interrupted in the mixed culture and the organisms entered into either a stationary or a death phase. none of the test coliform strains produced colicines active against shigella. an analysis of mixed-culture environments at the time shigella inhibition occurred revealed that the inhibition wa ...19694886281

carrier discretionary practices and physician payment under medicare part b: a preliminary report.although medicare is a national program, administration of part b payments to physicians is in the hands of insurance organizations in ten medicare regions. the carriers follow varying practices in using actual charges within localities as the basis for determining reasonable charges for physicians' services. while some of these practices have already been shown to influence fee levels, reasonable charge determination involves many more whose influence has not been systematically studied. this p ...1970376967

polyribosomes from bacillus subtilis during amino acid starvation in the presence and in the absence of actinomycin.polysomes were extracted from bacillus subtilis cells starved for a required amino acid. the monosome peak appeared soon after starvation; no difference in the rate of degradation was detected when the cells were starved for arginine or tryptophan in a double auxotroph. rna production during starvation was not inhibited by actinomycin, but the molecular weight of the product made in the presence of the antibiotic was much lower. indications that stable messenger ribonucleic acid is present for u ...19704191320

persistence of an escherichia coli-shigella flexneri hybrid in the intestinal tract of macaca mulatta.a live oral vaccine prepared from an escherichia coli-shigella flexneri 4b hybrid was administered by gavage to macaca mulatta. in the three main studies involving 160 monkeys, three doses were used, generally consisting of 5 x 10(9) to 60 x 10(9) cells per dose, with an interval between doses of 6, 7, or 14 days. rectal swab cultures at the time of the last vaccine dose, and 14 to 58 days later, revealed that the hybrid persisted in the intestinal tract for at least 7 days in 16%, and for at le ...19704987199

species differences in the aromatization of quinic acid in vivo and the role of gut bacteria.1. the fate of (-)-quinic acid has been investigated in 22 species of animals including man. 2. in man and three species of old world monkeys, i.e. rhesus monkey, baboon and green monkey, oral quinic acid was extensively aromatized (20-60%) and excreted in the urine as hippuric acid, which was determined fluorimetrically. 3. in three species of new world monkeys, i.e. squirrel monkey, spider monkey and capuchin, in three species of lemurs, i.e. bushbaby, slow loris and tree shrew, in the dog, ca ...19704985157

studies on vaccination against bacillary dysentery. 5. studies in erythrocebus patas.in earlier studies in man it has been demonstrated that streptomycin-dependent shigellae, if given orally in 5 sufficiently large doses, confer a very high type-specific protection against bacillary dysentery.in the present study, 2 groups of erythrocebus patas monkeys were immunized with live streptomycin-dependent shigella flexneri 2a, and a third group was not vaccinated. one of the vaccinated groups was given streptomycin with each dose of the live vaccine. the animals that received streptom ...19704993182

action of diethylstilbestrol on staphylococci: further observations on the effect of resting cells.diethylstilbestrol (ds) has been shown to be active against staphylococci and other gram-positive bacteria but not against gram-negative microorganisms. the present study extends these findings. standardized suspensions of (14)c-labeled staphylococcus aureus serotypes iii and iv and shigella flexneri were prepared and exposed to pharmacological concentrations of ds (1 to 20 mug/ml) under diverse environmental conditions; the cells were removed by membrane filtration and the presence of radioacti ...19704909354
