"February 2003." Addendum and corrigenda inserted at back Includes bibliographical references (leaves 249-272) Aims to identify and characterise potential virulence-associated factors from the locus of enterocyte effacement-negative shiga-toxigenic Escherichia coli O113:H21 strain 98NK2 which was responsible for an outbreak of haemolytic uremic syndrome. Particular attention was focused on putative virulence genes encoded on the megaplasmid of this strain.

Abstract (sommario):

Most bacterial infections can be correlated to contamination of consumables such as food and water. Upon contamination, boil water advisories have been ordered to ensure water is safe to consume, despite the evidence that heat-killed bacteria can induce genomic instability of exposed (intestine) and distal cells (liver and spleen). We hypothesize that exposure to components of heat-killed Escherichia coli O157:H7 will induce genomic instability within animal cells directly and indirectly exposed to these determinants. Mice were exposed to various components of dead bacteria such as DNA, RNA, p

Abstract (sommario):

Enterohaemorrhagic E. coli (EHEC) has been the causative agent of diarrhoeal outbreaks for decades. EHEC virulence relies on a type 3 secretion system (T3SS), which directly translocates T3SS effectors into the host cell cytoplasm. Once translocated, T3SS effectors alter various host cell functions, including manipulating the cell death response, in order to facilitate bacterial colonisation. EHEC is equipped with at least 40 effector proteins; however, not all identified effectors are fully characterised. This study set out to investigate the role of EspO during EHEC infection. EHEC O157:H7 s

Abstract (sommario):

Urinary tract infections (UTI) are one of the most common bacterial infections in hospital and community settings requiring antimicrobial treatment. Escherichia coli (E. coli), a bacterium frequently implicated in UTI, is becoming increasingly resistant to antimicrobials. Antimicrobial resistance (AMR) reduces the effectiveness of antimicrobial agents, leading to difficulty in treatment of patients, with the potential to prolong the duration of illness and increase mortality in patients. To date in Australia, there is a paucity of data comparing resistance patterns over time for hospital- and

Studies of extraintestinal infections caused by genetically related strains of Escherichia coli among unrelated people have demonstrated the epidemic potential of this group of bacteria. These related extraintestinal pathogenic E. coli (ExPEC) may have a common source. Our group recently described how retail meat, particularly chicken, may be a reservoir for ExPEC causing human urinary tract infections (UTIs). By moving upstream on the farm to fork continuum, this study tests whether the reservoir for ExPEC is in food animals themselves. A total of 824 geographically and temporally matched E.

Escherichia coli are usually regarded as a harmless human colonic flora. However, pathogenic strains of E. coli have been associated with infections that could range from infected mucosal surfaces by intestinal pathogenic E. coli to the more severe cases of disseminated infections throughout the body by the extraintestinal pathogroups. The main focus of this project was to investigate the genomic contents of pathogenic bloodstream infection (BSI)-associated E. coli strains. This is because the genome contents of the E. coli BSI-associated isolates have not been well studied, with only few repo

Abstract (sommario):

Enterohemorrhagic E. coli (EHEC) is a major cause of food borne diarrheal illness worldwide. While disease symptoms are usually self-resolving and limited to severe gastroenteritis with bloody diarrhea, EHEC infection can lead to a life threatening complication known as Hemolytic Uremic Syndrome (HUS), which strikes children disproportionately and is the leading cause of kidney failure in children. Upon infection of gut epithelia, EHEC produces characteristic lesions called actin pedestals. These striking formations involve dramatic rearrangement of host cytoskeletal proteins. EHEC hijacks mam

Abstract (sommario):

Abstract Urinary tract infections (UTIs) are among the most common bacterial infections in childhood and have a tendency to recur. The ability of uropathogens to form biofilm may be important in the pathogenesis of UTI. Although childhood UTIs are thought to increase the risk of chronic kidney disease (CKD), evidence showing this association is scarce. Cranberry juice has been shown to prevent UTIs in women, but evidence of its efficacy in children is lacking. The aim of this work was to evaluate the significance of biofilm formation for the clinical presentation of UTI, the long-term conseque
