Escherichia coli Strain Diversity in Humans: Effects of Sampling Effort and Methodology
… investigating <em>Escherichia coli</em> strain diversity and demographics in human hosts are frequently inconsistent regarding sampling effort and methodology while current strain typing methods are often expensive or laborious. To rectify these inconsistencies, sampling effort was …

Genetic diversity in Neospora caninum
… were used successfully to genotype different strains of N. caninum which were isolated from bovine and canine hosts and from different geographical regions of the world. Several mini- and microsatellites were identified that detected differences among different isolates of this parasite. A …

Molecular epidemiology, susceptibility profiles, outcomes and transmission dynamics in patients with extensively drug-resistant tuberculosis (XDR-TB) in two provinces of South Africa
… October 2012 and followed up till October 2014. Strain typing and drug susceptibility testing were performed and treatment-related outcomes were determined. In-depth interviews were conducted with therapeutically destitute patients from cohort B (n=12) and were home-discharged from hospital back …

Streptococcus equi subsp. zooepidemicus in New Zealand horses
… within the New Zealand horse population through strain-associated genomic and phenotypic characteristics. Retrospectively, S. zooepidemicus is the second most frequently isolated bacterium in New Zealand horses, being mainly associated with respiratory and urogenital tract infections. However, it …

Demographics and Transfer of Escherichia coli Within Bos taurus Populations
… the United States, symptoms caused by pathogenic strains of <em>Escherichia coli</em> are on the rise. A major source of these pathogenic strains is the <em>E. coli</em> in the digestive tract of cattle. The purpose of this project was to determine if <em>E. coli</em> are transferred between …

Integrative Genomic Approaches for Plant Trait Discovery, Fungal Pathogen Identification and Taxonomy
… surveillance, yet its application remains constrained by incomplete detection of complex genetic variation, difficulty recovering pathogen genomes directly from diseased tissues, and inconsistent reference resources for fungal and oomycete identification. This dissertation integrates long-read …

Use of molecular and bioinformatics tools for developing methods of epidemiological identification of trypanosomes
… at all levels (species, subspecies, populations, strains and isolates). Commonly, field samples are collected and stored using Whatman FTA cards. Many molecular epidemiological tools are available for detection and strain typing in trypanosomes. These tools include nested ITS-PCR, which is based …

Regulation of to xin Synthesis By Clostridium Difficile
… exponentially in the last decade. Virulent strains of <em>C. difficile</em> produce either toxin A and/or toxin B, which are essential for the pathogenesis of this bacterium. Current methods for diagnosing CDI are mostly qualitative tests that detect the bacterium, the toxins, or the toxin …

Population genetic frameworks and functional genomics of Mycobacterium bovis
… national and international surveillance of strain distribution dynamics in the population. To date, piecemeal analysis of Mycobacterium bovis genomes and conventional genotyping methods have not themselves lent to a comprehensive resolution of its genetic diversity to explain the wide range …
