Amoxicillin therapy of poultry flocks: effect upon the selection of amoxicillin-resistant commensal Campylobacter spp. (2009)

Elviss, Nicola C., Williams, Lisa K., Jørgensen, Frieda, Chisholm, Stephanie A., Lawson, Andrew J., Swift, Craig, ...

Background The aim of this study was to investigate the effect of amoxicillin therapy of poultry flocks upon the persistence of commensal Campylobacter spp. and the incidence of antibiotic...

Mutations in Helicobacter pylori rdxA gene sequences may not contribute to metronidazole resistance (2003)

Chisholm, Stephanie A., Owen, Robert J.

Metronidazole resistance in Helicobacter pylori reportedly occurs by mutational inactivation of the oxygen-insensitive nitroreductase gene rdxA. Nucleotide sequences of rdxA were determined in a set...

PCR-Based Diagnosis of Helicobacter pylori Infection and Real-Time Determination of Clarithromycin Resistance Directly from Human Gastric Biopsy Samples

Chisholm, Stephanie A., Owen, Robert J., Teare, E. Louise, Saverymuttu, Seth

A novel PCR detection assay that amplifies the Helicobacter pylori-specific vacuolating cytotoxin gene (vacA) and thus enables rapid diagnosis of infection is described. Additionally, a real-time...

Identification of cagA Tyrosine Phosphorylation DNA Motifs in Helicobacter pylori Isolates from Peptic Ulcer Patients by Novel PCR-Restriction Fragment Length Polymorphism and Real-Time Fluorescence PCR Assays

Owen, Robert J., Sharp, Sally I., Chisholm, Stephanie A., Rijpkema, Sjoerd

Cag pathogenicity island-containing Helicobacter pylori (type I) induces signal transduction pathways resulting in tyrosine phosphorylation of proteins adjacent to the site of bacterial adhesion on...
