Abstract (sommario):

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. In this study intimate adherence of EPEC to surfaces of cult

Abstract (sommario):

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

Abstract (sommario):

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

Abstract (sommario):

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. The goal of this study was to identify and characterize a lin

Abstract (sommario):

Expansion of the genetic code through engineering of the translation machinery has vastly increased the chemical repertoire of the proteome. Incorporation of non-canonical amino acids (ncAAs) entails use of engineered aminoacyl-tRNA synthetase (AARS)•transfer RNA (tRNA) pairs that do not interact with the canonical aminoacylation machinery. Although engineered AARSs are selected for their ability to utilize ncAAs and discriminate against the twenty canonical amino acids, many utilize other ncAAs – a phenomenon known as polyspecificity. Specific incorporation of multiple ncAAs in a single polyp

Recently, comparative genomics studies revealed that the ompW gene is a core regulon of the global transcription factor FNR (Fumarate Nitrate Reduction) which mediates the transition from aerobic to anaerobic lifestyle of facultative bacteria.

Abstract (sommario):

Escherichia coli (E.coli) 0157:H7, a pathogen belonging to the enterohemorrhagic group of E.coli, has long been a concern to human health. The pathogen causes a myriad of symptoms in humans, ranging from diarrhea and malaise to renal failure. Human infection with the spread of the pathogen is mainly attributed to consumption of contaminated food material such as meat. Decontamination of meat via sprays have to date been the most commonly practiced method to reduce contamination, which now has little relevance in the face of developing resistance by the pathogen.

Several genes, essential for cell growth and division in Escherichia coli, have been mapped to the 76 minute region of the chromosome. DNA sequencing of part of this region revealed three cell division genes (ftsY, ftsE, and ftsX) in a putative operon. A fourth gene (orf4) was also identified that was transcribed in the opposite direction to the putative operon. The genes rpof, f am, dnaM and ftsS have also been mapped to this region, but their location, relative to the putative operon, was unknown. In this study the fam and rpoU genes were independently cloned and shown to be allelic. The dna

Abstract (sommario):

To maintain genomic integrity, all cells must accurately duplicate their genetic material in order to provide intact and complete copies to each daughter cell following cell division. Successful inheritance of chromosomal information without changing even a single nucleotide requires accurate and robust DNA replication. This requires that cells tightly control replication initiation from the origin(s), processive elongation of the replisome, and the completion of DNA replication by resolving convergent replication forks ensuring that each sequence is duplicated without alteration.

Abstract (sommario):

Mutations in the ruv gene of Escherichia coli K-12 result in an increased sensitivity to agents that damage DNA. Studies presented in this thesis demonstrate that the ruv gene product is required for conjugational recombination in certain genetic backgrounds. From this it was inferred that the role of the ruv gene product was in the recombination repair of daughter strand gaps and double strand breaks in damaged DNA. In addition, the ruv gene product is shown to be required for the efficient recovery of F' transconjugants in certain genetic backgrounds, suggesting that recombination between tr
