Innovative molecular methods for fish species differentiation
This thesis presents the results of a proof-of-principle study in which a rapid screening method for various market-relevant fish species have been developed. A DNA microarray was established using a set of 100 universal oligonucleotide probes. DNA probe signal patterns were observed to be …

Authentication of Species in Bison Products Using Molecular Methods
<p>American bison (<em>Bison bison</em>) meat is vulnerable to species substitution due to its high value and similar appearance to less expensive meats, such as beef from domestic cattle (<em>Bos taurus</em>). DNA barcoding of the cytochrome <em>c </em>oxidase subunit 1 (CO1) gene is a commonly …

Investigation of bacteria associated with Australian wine grapes using cultural and molecular methods
… species using a combination of cultural and molecular methods. Red (Shiraz, Cabernet Sauvignon, Merlot) and white (Chardonnay, Semillon, Sauvignon Blanc) grape varieties were examined. Factors affecting the bacterial ecology of grapes were considered. The bacterial populations of mature …

Use of Molecular Methods to Authenticate Animal Species and Tissue in Bovine Liver Dietary Supplements
… to fraud due to the lack of modern detection methods available for processed animal tissues and premium pricing for dietary supplements. Therefore, the objective of this research was to use molecular methods to authenticate dietary supplements claiming to contain “bovine liver” or “beef liver” …

Investigation into the use of molecular methods to distinguish between species of Caladenia subgenus Calonema
The phylogeny of typical spider orchid (Caladenia subgenus Calonema) is investigated for the first time. The analyses were performed using 17 RAPD and 10 ISSR primers on 30 taxa representing the three spider orchid groups (the dilatata, patersonii and reticulata groups) yielding 135 RAPD and 63 …

Applying molecular methods to investigate potential anthropogenic impacts on ageing in a free-living bat species
… sensitive to disturbance, subtle changes at the molecular and microbial level may provide an early indication of population-level impacts. This thesis examines whether diAerences in ageing and gut microbiome between two colonies of Bechstein’s bat (Myotis bechsteinii), a long-lived woodland …

Geomicrobiology of nitrogen in a coastal aquifer : isotopic and molecular methods to examine nitrification and denitrification in groundwater
… groundwater systems. Here we use isotopic and molecular biological methods to identify the populations of nitrifiers and denitrifiers, where they occur, and what levels of activity are present through the upper four meters of a coastal groundwater system. This work shows two different …

Molecular methods for the detection of TEM- and SHV-related beta lactamase genes in members of the Enterobacteriaceae
… primary aim of this study was to evaluate two molecular techniques for the detection of SHY and TEM-related genes in clinical isolates. The study sample consisted of 209 clinical isolates of enteric Gram negative bacilli, isolated at Groote Schuur Hospital microbiology laboratory. The isolates …

An Alternative Method to Concentrate E. coli O157:H7 from Meat Homogenates to Facilitate Detection by Cultural and Molecular Methods
… illness per year. Sensitive and efficient methods to detect this organism are crucial. Current bacterial concentration methods from foods, such as centrifugation and filtration, are problematic, often co-precipitating or becoming clogged with food particulates. Metal hydroxide concentration …

Detection of the calreticulin type 1 and type 2 mutations in a group of myeloproliferative neoplasm patients using molecular methods
The myeloproliferative neoplasms (MPN), formerly referred to as chronic myeloproliferative disorders, are a group of haematopoietic stem cell disorders that are characterized by clonal proliferation of one or more mature myeloid lineages. The group of disorders, now classified as the classic MPNs, …
