| shigellosis in the united states: ten-year review of nationwide surveillance, 1964-1973. | in the 10 years 1964-1973, 105,832 isolations of shigellae were reported to the center for disease control through a nationwide surveillance system. the number reported increased by approximately 13% annually, from 5852 in 1964, when only 17 centers reported all 4 quarters; to 16,797 in 1973, when 52 centers reported each quarter. the rate of reported isolations varied from 4.6 per 100,000 persons in 1965 to 9.1 per 100,000 in 1973. shigella sonnei accounted for 64% of all these isolates and for ... | 1976 | 790947 |

| studies on the energetic metabolism of shigella flexneri x escherichia coli hybrids devoid of penetration ability. iv. growth characteristics in the presence of some tricarboxylic acid cycle intermediates. | the dynamics of avirulant lac+kcp- hybrids sh. flexneri multiplication was investigated in minimal medium in the presence of some tricarboxylic acid cycle intermediates (fumarate, succinate, malate) and pyruvate. it was established that in spite of the loss of virulence in the rate of the multiplication of the hybrid strains, in comparison with that of the virulent recipient strains of sh. flexneri, considerable differences were not observed. | 1976 | 793258 |
| [free amino acid content in the blood and urine from the use of monomycin on children with dysentery]. | the progress of acute dysentery in 73 children at the age of 1 to 14 years treated with monomycin and the levels of free amino acids in the blood and urine in dynamics were studied. it was found that the blood levels of 6 amino acids in the children treated with the antibiotics significantly decreased, while those of 3 amino acids increased as compared to the levels of the same amino acids in the children treated without the antibiotics. it was concluded that the diet of dysentery children treat ... | 1976 | 793513 |
| [change in the sensitivity of dysentery bacteria to certain antibiotics, furazolidone and antifungal preparations when cultured together with candida albicans]. | the effect of candida albicans (2 collection cultures and 1 freshly isolated culture) on sensitivity of dysentery bacteria (5 zonne strains, 4 flexner strains and 2 newcastle strains) to antibiotics, furazolidone and their combinations with nystatin or decamine was studied by the method of serial dilutions. a total of 937 tests were performed with the use of 10 concentrations in each test. it was found that sensitivity of the shigella to levomycetin succinate, monomycin and furazolidone decrease ... | 1976 | 793515 |
| studies on the relationships between the immunogenicity and catabolism of antigens and their binding to the surface of macrophages. | the relationship between immunogenicity of shigella paradysenteriae, the branched synthetic polypeptide poly-l (tyr, glu)-polylpro-polyllys [(t, g)-pro--l] and human albumin (hsa) interacting with macrophages and kinetics of antigen degradation and degree of binding to the cell surface was studied. following thioglycollate inoculation into c57bl/6 mice, the peritoneal-stimllated macrophages had higher levels of hydrolases as compared to unstimulated cells. the lysates of the stimulated macrophag ... | 1976 | 793850 |
| [formation of f'-episomes in flexner shigellae]. | genetic characteristics of shigella flexneri virulent donor strain 3s, isolated in the laboratory, are studied. the data obtained showed that sh. flexneri 3s 6832 is of f'protype it did not transmit even closely located chromosome markers, except pro+. the transition of pro+ marker was reproduced in reca- strain. f'pro plasmid was eliminated with a frequency similar to that of f'lac factor in the control strain of escherichia coli. the study of virulence by means of keratoconjunktival test revea ... | 1976 | 793929 |
| phage-dependent changes in shigella flexneri type antigen synthesis. | lysogenic conversion of shigella flexneri type antigens was studied with the aid of wild-type and thermosensitive mutant phages. with all wild-type phages, the appearance of glycosylated antigen was accompanied by the appearance of polyprenyl phosphate glucose synthetase activity. with some of the mutant phages, the appearance of glycosylated antigen was not followed by the formation of lipid-linked glucose in the enzyme assay. the reverse has also been observed, i.e., the high rate of formation ... | 1976 | 793990 |
