Résumé :

Abstract This study examines the intrinsic fitness burden associated with RNA polymerase (rpoB) mutations conferring rifampin resistance in Escherichia coli K12 (MG1655) and explores the nature of adaptation to the costs of resistance. Among 28 independent Rifr mutants, the per-generation fitness burden (in the absence of rifampin) ranged from 0 to 28%, with a median of 6.4%. We detected no relationship between the magnitude of the cost and the level of resistance. Adaptation to the costs of rif resistance was studied by following serial transfer cultures for several Rifr mutants both in the p

Résumé :

Abstract Chimeras of RNA and DNA have distinctive physical and biological properties. Chimeric oligonucleotides that contained one, two or three ribonucleotides whose phosphodiester backbone was covalently continuous with DNA were synthesized. Site-directed mutagenesis was used to assess genetic information transfer from the ribonucleotide positions. Transfer was scored by the formation or reversion of an ochre site that also corresponded to a restriction cleavage site. This allowed physical as well as genetic assay of mutational events. Bases attached to the ribonucleotides were able to accur

Résumé :

Abstract Homologous recombination in Escherichia coli is enhanced by a cis-acting octamer sequence named Chi (5′-GCTGGTGG-3′) that interacts with RecBCD. To gain insight into the mechanism of Chi-enhanced recombination, we recruited an experimental system that permits physical monitoring of intramolecular recombination by linear substrates released by in vivo restriction from infecting chimera phage. Recombination of the released substrates depended on recA, recBCD and cis-acting Chi octamers. Recombination proficiency was lowered by a xonA mutation and by mutations that inactivated the RuvABC

ABSTRACT Searches for alkylation-inducible (aid) genes of Escherichia coli have been conducted by screening random fusions of the Mu-dl(ApR lac) phage for fusions showing increased β-galactosidase activity after treatment with methylating agents, but not after treatments with UV-irradiation. In this report we describe gene fusions that are specifically induced by alkylation treatments. Nine new mutants are described, and their properties are compared with the five mutants described previously. The total of 14 fusion mutants map at five distinct genetic loci.

Résumé :

The isolation and description of Bacillus coli commune by Escherich a hundred years ago marked the start of a series of scientific investigations which have led to some of the most important discoveries in microbial pathogenicity and genetics that have been made since that time. It is not difficult to find the reasons why so much effort has been concentrated on this organism. Escherichia coli is present in the gut of all warm-blooded animals generally forming the predominant aerobic flora; it is of medical and veterinary importance being responsible for a variety of infections in the human and

Résumé :

Abstract The nucleotide sequences of the gapA and pabB genes (separated by approximately 32.5 kb) were determined in 12 natural isolates of Escherichia coli. Three analyses were performed on the data. First, the levels of polymorphism at the loci were compared within and between E. coli and Salmonella strains relative to their degrees of constraint. Second, the gapA and pabB loci were analyzed by the Hudson-Kreitman-Aguadé (HKA) test for selective neutrality. Four additional dispersed genes (crr, putP, trp and gnd) were added to the analysis to provide the necessary frame of reference. Finally

Colonization of gut mucosal surfaces by enteropathogenic Escherichia coli (EPEC) elicits a severe persistant diarrhoea in infants and young children without elaboration of enterotoxins or tissue invasion. The formation of a distinct ultrastructural lesion involving intimate adherence to cell surfaces, loss of microvilli and membrane perturbations, however, has for some time been recognized as an important component of pathogenesis, but the processes involved in lesion formation and its relevance to the disease state remained obscure.

Résumé :

The expression of genes is tightly controlled, predominantly at the point of transcription. RNA polymerase (RNAP) must first bind to a deoxyribonucleic acid (DNA) promoter upstream of a gene to transcribe it. However, the ability of RNAP binding is dictated by the core promoter DNA sequence, the presence of transcription activator or repressor proteins and numerous other factors. The strength of promoters has been indirectly measured. Only a few studies have attempted to directly address the RNAP flux through transcription units, and further studies are still required. In the current study, th

Previous genetic evidence suggested that RecA was required in SOS mutagenesis for its regulatory role and perhaps some other nonregulatory role (Mount, 1977; Blanco et al., 1982). I undertook a genetic study which confirmed the above studies and provided further evidence that RecA protein appeared to have a dual "role in mutagenesis; first, the cleavage of LexA repressor for the derepression of specific SOS genes and second, one or more additional role(s). For these studies a new phage mutagenesis assay was developed which allows rapid scoring of SOS mutagenesis in a large number of host mutan

Shiga toxin-producing E. coli (STEC) including E. coli O157:H7 are potential food and water borne zoonotic bacterial pathogens capable of causing outbreaks of severe illness in humans. The virulence of E. coli O157:H7 strains may be related to the type of Stx produced and several Stx2 variants have been identified which appear to differ in their ability to cause disease. Two lineages exist within O157 strains where lineage I is associated mainly with human and bovine isolates and lineage II is associated mainly with bovine isolates.

Résumé :

Genetic engineering is an actively developing branch of modern biotechnology. Using the methods of genetic engineering, it is possible to construct new forms of microorganisms that can synthesize a variety of substances, including enzymes. Xanthosine phosphorylase is the second purine nucleoside phosphorylase (PNP-II) in E. coli. This enzyme performs both reactions of phosphorolysis and the synthesis of purine deoxy / ribonucleosides. Due to this ability, xanthosine phosphorylase can catalyze the reaction of the formation of nicotinamide riboside. This substance is a precursor of the most impo

Subsequently, genetic techniques cure applied to localize the mutation, while the nature of the impairedfunction could be determined using biochemical methods.
