Abstract:
Johne’s disease, caused by Mycobacteria avium subsp. paratuberculosis (MAP), plagues cattle and dairy farmers worldwide. Infected animals suffer from chronic granulomatous enteritis, reduced fertility, decline in milk production and emaciation. It is spread through colostrum, milk and faeces. Johne’s disease has also become strongly associated with human Crohn’s disease due to the similarity in symptoms and the presence of MAP in samples taken from Crohn’s disease patients. Currently there is not cure for Johne’s disease, therefore, routine testing and isolation or culling of diseased animals

Abstract:
Current studies of koalas in the wild mainly rely on information gathered by traditional field methods, such as community sightings, spotlighting, radiotracking, animal trappings, ear tagging and faecal pellet incidence. Collection of faeces is potentially the most reliable source of non-invasively obtaining DNA samples, which can be used to identify specific individuals. This thesis demonstrated a simple, rapid and reproducible method of extracting DNA from Koala faecal pellets using a commercially available DNA extraction kit, shows the maximum age of pellets from which DNA can be reliably e

The National Monitoring Program for Large Carnivores monitors the Swedish lynx population (species Lynx lynx) by surveying family groups, non-invasive sampling and genetic analysis. Ten microsatellite regions were used as genetic markers to retrieve unique individual genotypes, through polymerase chain reactions (PCR) with specific primer-pairs and capillary-electrophoresis. Complete genotypes were matched using an internal database. The aim of this degree project was to show ho

Abstract:
O gênero Mazama é composto por cinco espécies no Brasil. São animais de visualização dificultada por causa de comportamentos evasivos, o que torna as capturas e os estudos comportamentais quase impossíveis. Assim, o uso de metodologias não invasivas para estudos ecológicos e genéticos destas espécies se torna necessário. A análise do DNA fecal está dentro das técnicas mais promissoras para esse fim. Este estudo objetivou genotipar amostras fecais, de uma população de veado-mateiro (Mazama americana) para a obtenção de informações genéticas e ecológicas. Para tanto, foram coletadas, com auxílio

O veado-mão-curta (Mazama nana) é uma espécie de cervídeo que ocupa a região Sul do Brasil, norte da Argentina e leste do Paraguai, tendo sido severamente afetada pela redução drástica das áreas florestadas. Trata-se, também, da espécie de cervídeo neotropical menos estudada pela ciência. Frente a essa situação, o presente projeto propôs-se a entender como essa espécie se distribui em sua área de ocorrência, propôs áreas prioritárias para sua conservação e estimou a densidade de duas populações. Dada a raridade e a alta elusividade da espécie, propôs-se o uso de metodologias indiretas para se

Abstract:
The field of conservation genetics, in combination with non-invasive sampling, provides a powerful set of tools for investigating the conservation status and natural history of rare species that are otherwise difficult to study. A systematic literature review demonstrated that this is certainly the case for many forest associated antelope species, which are poorly studied and yet constitute some of the most heavily hunted wildlife in Africa. The aim of the present study was to use non-invasive sampling to investigate genetic patterns in forest antelope populations in the high-biodiversity Udzu

Abstract:
Recent metagenomic studies have shown that there is a higher diversity of ssDNA viruses in the environment than previously thought. While some viral families are well characterised, novel ssDNA isolates discovered with sequence-independent molecular techniques are often too divergent to fit within the currently established viral taxonomy. Several factors have contributed to the gap in knowledge, including: the (previously) high cost of sequencing, the disproportionate amount of research that occurs after a threat is identified, and the use of sequence-based molecular techniques to isolate vira
