| mutation in shigella flexneri 2a resulting in increased electrophoretic mobility. | an avirulent mutant of shigella flexneri 2a, when grown in broth containing calcium ions, was found to have a three- to fourfold increase in electrophoretic mobility toward the anode when compared to its virulent parent. under these same growth conditions, it was found that the avirulent strain was made more electronegative in the presence of ethylenediaminetetraacetic acid (edta). edta had no effect on the electrophoretic mobility of the virulent strain. in the absence of added calcium in the g ... | 1972 | 4629253 |

| 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 |

| virulence of shigella flexneri hybrids expressing escherichia coli somatic antigens. | the genes controlling either escherichia coli somatic antigen 8 or 25 were conjugally transferred to virulent shigella flexneri 2a recipients to determine whether the aquisition of these antigens would affect the virulence of the resulting hybrid. a high proportion of such hybrids were found to be rough and hence were avirulent. some smooth s. flexneri hybrids which replaced their native group antigens with e. coli factor 25 were still virulent in the animal models employed. all s. flexneri o-8 ... | 1972 | 4569915 |

| factors affecting virulence of shigella flexneri: strain with relaxed control of ribonucleic acid synthesis. | an escherichia coli-shigella flexneri hybrid strain which produces an abortive, nonfatal experimental dysentery has inherited relaxed control of ribonucleic acid synthesis from its e. coli parent. this property, coupled with a partial methionine requirement, has been used to explain its long lag phase in vitro, relative to its shigella parent. it was suggested that such characteristics may contribute to the hybrid's poor survival in the gut resulting in the abortive infection. | 1972 | 4570983 |

| behavior of coliphage lambda in shigella flexneri 2a. | the insensitivity of wild-type shigella flexneri 2a to coliphage lambda is a consequence of its native genetic defect in the mala gene cluster. the "smooth" s. flexneri 2a lipopolysaccharide layer affects the efficient adsorption of lambda. derivatives, capable of serving as functional hosts for lambda, were obtained by repairing the mala lesion, enabling the expression of the malb-lambdarcp region of s. flexneri. introduction of a mutation into s. flexneri causing a "rough" lipopolysaccharide c ... | 1972 | 4563593 |

| factors affecting virulence of shigella flexneri: defective methionine synthesis in an escherichia coli-shigella hybrid. | an escherichia coli-shigella flexneri hybrid of intermediate virulence was studied to determine whether its shorter survival in host cells might be due to a metabolic defect. investigation of its growth in minimal glucose medium showed that the hybrid, like its e. coli parent, had a longer lag phase and a slower growth rate than its virulent shigella parent. methionine was found to increase the growth rate of the hybrid. the shigella parent of the hybrid can synthesize methionine normally, but t ... | 1972 | 4562393 |
| transfer among erwinia spp. and other enterobacteria of antibiotic resistance carried on r factors. | antibiotic resistance carried on r factors was transferred by conjugation from escherichia coli b/r and shigella flexneri 1a to erwinia spp. tetracycline resistance (tetr) carried on r factor r100 drd-56 was transferred from e. coli b/r to strains of erwinia amylovora, e. aroideae, e. atroseptica, e. chrysanthemi, e. cytolytica, e. dissolvens, e. herbicola, e. nigrifluens, and e. nimipressuralis, but not to strains of erwinia carotovora, e. carnegieana, e. dieffenbachiae, e. oleraceae, and e. qu ... | 1972 | 4562410 |
| importance of facilitated diffusion for effective utilization of glycerol by escherichia coli. | wild-type escherichia coli possesses an inducible permeation system which catalyzes facilitated diffusion of glycerol into the cell. a spectrophotometric method can be used to assess the presence of this mechanism. the structural gene for the facilitator (glpf) and the structural gene for glycerol kinase (glpk) apparently belong to a single operon. the glpf(+) allele permits effective glycerol utilization by the cells, and, at millimolar concentrations of glycerol, cells carrying the glpf(+) all ... | 1972 | 4563976 |
