| the occurrence of folic acid (pteroyl-l-monoglutamic acid) in human blood serum after small oral doses. | human serum folates analysed by bioautography after oral doses of 0.5 mg folic acid (pteroyl-l-monoglutamic acid) show folic acid to be present. | 1972 | 4625432 |
| trimethoprim-sulphamethoxazole in urinary tract infection due to streptococcus faecalis. | in-vitro sensitivities were performed on 140 specimens of urine which grew streptococcus faecalis of more than 100 000 organisms/ml between march 1970 and february 1971. although the combination of trimethoprim and sulphamethoxazole definitely appeared to be more effective than sulphonamide alone and as effective as ampicillin, its use for more than two weeks in 14 cases of uncomplicated urinary tract infection due to streptococcus faecalis led to development of resistance. as in these cases org ... | 1972 | 4625437 |

| the combination of trimethoprim and sulfamethoxazole in the treatment of urinary tract infection. | in a series of 52 patients the combination of trimethoprim and sulfamethoxazole was used for the treatment of urinary tract infection and the results are analyzed with respect to the clinical diagnosis and bacterial etiology. there was complete agreement between in vitro sensitivity and clinical response except in the case of one strain of streptococcus fecalis. the combination of drugs was effective against some bacterial strains which were resistant to the commonly used antimicrobial agents. | 1972 | 4626767 |
| evaluation and standardization of an agglutination test for human listeriosis. | human sera from patients with culturally confirmed listeriosis were tested for immunoglobulin m (igm) and immunoglobulin g (igg) agglutinating antibodies with trypsinized antigens of listeria monocytogenes, streptococcus faecalis, and staphylococcus aureus. the response of humans to listeria infections is mainly igm rather than igg as found in animals. the antigens prepared from l. monocytogenes serotypes 1a, 1b, 2, 4b, and 4d were evaluated for specificity with normal sera, sera from patients w ... | 1972 | 4626902 |

| folate metabolism in streptococcus faecalis. | the possibility that the inability of streptococcus faecalis to utilize 5-methyltetrahydropteroylglutamate or pteroyltriglutamate might be due to permeability was investigated. whereas the former was taken up by s. faecalis cells growing on pteroylglutamic acid, the latter was not. no subsequent conversion of the 5-methyltetrahydropteroylglutamate took place and accumulation, which was against a considerable concentration gradient, was inhibited by fluoride. it would thus appear to be an active ... | 1972 | 4627689 |
| the lipid-teichoic acid complex in the cytoplasmic membrane of streptococcus faecalis n.c.i.b. 8191. | 1. a lipid-teichoic acid complex was isolated from streptococcus faecalis n.c.i.b. 8191. the covalent nature of the linkage between teichoic acid and lipid was established. 2. the complex exhibits macromolecular properties in solution, and ultracentrifugation studies show that these are due to micelle formation. 3. from chemical studies it is concluded that the teichoic acid is a poly(glycerol phosphate) in which some of the glycerol hydroxyl groups possess kojibiosyl [2-o-alpha-d-glucopyranosyl ... | 1972 | 4627730 |
| quantitative sputum culture as a means of excluding false positive reports in the routine microbiology laboratory. | a relatively simple technique for sputum homogenization and dilution is described. results show that this technique is reliable for isolation and quantitative culture of organisms from cases of chest infection. the technique has resulted in significant reduction in false positive reports, particularly when a system of interpretative reporting is utilized based on 10(7) organisms per millilitre of sputum being accepted as evidence of significant infection. | 1972 | 4627746 |

| function of various intestinal bacteria in converting germfree mice to the normal state. | earlier work had shown that a collection of anaerobic bacteria, in conjunction with facultative anaerobes, may be implanted into germfree mice, thereby rendering the animals "normal" with respect to a variety of parameters tested. the present experiments indicate that a different collection of anaerobic bacteria, isolated from the cecum of normal mice, was necessary to convert germfree mice to the "normal" state when the animals were fed a crude diet, rather than the refined food which had been ... | 1972 | 4631910 |
| experimental shigella infections in laboratory animals. i. antagonism by human normal flora components in gnotobiotic mice. | germfree mice were associated with selected species of human intestinal bacteria and then challenged with a streptomycin-resistant shigella flexneri strain. antagonism against shigella was most pronounced in mice associated with escherichia coli and least pronounced in mice associated with bacteroides fragilis. a moderate degree of antagonism could be demonstrated in mice associated with either streptococcus faecalis or bifidobacterium adolescentis. shigella persisted in the cecal contents of e. ... | 1972 | 4631914 |
| growth of streptococcus faecium in the presence of lysozyme. | streptococcus faecium can grow normally in the presence of lysozyme, despite the observation that cell suspensions of the organism are lysed readily by the enzyme. growth in the presence of lysozyme is not due to resistant cells, and the culture is lysed after growth if the ph of the medium is not allowed to drop too low for lysozyme activity. growth followed by lysis in the presence of lysozyme was not exhibited by other organisms tested which were either significantly more resistant or more se ... | 1972 | 4631915 |
