Abstract:

Parasites can impose fitness effects on host populations: there may be seasonal and geographic variation in the interaction as well as over a longer time scale, host-parasite cospeciation. I investigate the Leucocytozoa parasites of birds as a model system to try to understand the role of diversity of infection, dispersal and scale on the nature of the coevolutionary process between the hosts and parasites. Leucocytozoa had effects on the breeding success of a population of the blue tit, Cyanistes caeruleus. Number of infections was important, and old birds infected with mixed lineage infectio

Abstract:

The development of a vaccine is essential for the elimination and eventual eradication of malaria. However, despite many years of effort, a successful malaria vaccine has not yet been achieved. Many of the subunit vaccine candidates tested in clinical trials have provided limited efficacy; therefore, efforts to develop an effective vaccine against malaria need to continue. The development of a whole parasite blood-stage vaccine would maximise the number of blood-stage antigens presented to the immune system, including conserved parasite antigens. Chemical treatment has been used to develop att

Abstract:

<p>Leishmaniasis is a disease affecting more than 12 million people worldwide. It is caused by the protozoan parasite Leishmania, which is transmitted to humans and dog hosts through bites of infected sand flies belonging to genus Phlebotomine. Several studies have shown Polymerase Chain Reaction (PCR) to be effective for the diagnosis of VL in clinical samples compared to the classical methods. The aims of this study were first to compare four different sample preparation methods for the PCR diagnosis of visceral leishmaniasis (VL) using peripheral blood samples and furthermore to find a meth

Abstract:

Malaria was identified as one of the first infectious diseases recognised to spread through blood transfusion. Although transfusion acquired malaria is rare, nevertheless it can be lethal if it not diagnosed or treated immediately. It is a continuous challenge for the blood services to identify and exclude asymptomatic malaria infected donors, while minimising the exclusion of uninfected donors. The diagnostic tests in current use present certain limitations which include the use of inherently antigenically variable vaccine candidate proteins that have limited sensitivity against all human mal

Tasmania’s apex predator the Tasmanian devil (Sarcophilus harrisii) is under threat from multiple sources including devil facial tumour disease (DFTD) and as a result is now classified as endangered.

The present study analysed ticks and tick-borne protozoal pathogens of devils to gain an understanding of what haemoprotozoan pathogens are present in devils and ticks collected from them.

Abstract:

Historically, diagnosis has relied on clinical signs of disease, microscopy and serological testing. However, these approaches have a number of drawbacks for example, differential diagnosis, low sensitivity (microscopy) and the inability to differentiate past from current infections (serology). In the past decade the use of molecular techniques, such as the polymerase chain reactions (PCR) have gained favour. Many research groups have used these techniques to study the molecular epidemiology of diseases in sub-Saharan Africa. Such methodologies rely on the detection of genetic materials and as

Abstract:

Drug resistance is one of the most medically relevant forms of pathogen evolution. To date, vaccines have not failed with the same depressing regularity as drugs. Does that then make vaccines evolution-proof? In the face of vaccination, pathogens are thought to evolve in two ways: by evolving epitope changes at the antigenic target of vaccination (epitope evolution); or by evolving changes at other antigenic loci, some of which may involve virulence (virulence evolution). The fundamental difference between these two forms of evolution is that virulence evolution could lead to disease outcomes

Abstract:

Life-history is the study of all the different stages of life that affect reproductive success and survival between the birth and death of an organism. The reproductive output of an organism is constrained by many things including time, resource, disease agents and environmental conditions. In addition, lineage-specific traits and the limitations of the physiological systems can limit how an organism responds to ecological processes, and thus constrains the variation of life histories represented in nature. Central to the theory of life history are the trade-offs that organisms make during the

Abstract:

This thesis examined the molecular mechanisms that are at the basis of parasite-host interactions during malaria infection, specifically focussing on antibody function and interactions during inflammation. Plasmodium parasites were recently discovered to grow slower during acute infection. This project built on that evidence and identified a role for inflammation as well as detected an initial response by the parasite to inflammation.

Master of Science<br>Department of Biology<br>David A. Haukos<br>Abstract–Duckling Survival Lesser scaup (scaup) populations have been experiencing continent-wide decline since the 1980s. It is important to have complete understanding of the critical factors influencing population change (e.g., duckling survival, nesting success, and health) to advance our understanding of population dynamics and improving species conservation. Duckling survival is a primary driver of scaup demography. I conducted a capture-mark-recapture study using Cormack-Jolly-Seber models in Program MARK to compute appar

Abstract:

A favorable outcome of blood-stage malaria infection requires immune responses that effectively eliminate the infection with minimum pathology to the host. There is strong evidence that the innate immune system is critical for initiating and shaping the subsequent adaptive immune response to blood-stage Plasmodium parasites. As sentinels of infection and potent activators of immunity, dendritic cells (DCs) are pivotally positioned to control the immune response to malaria and thereby influence the outcome of infection. Experiments performed in this thesis work aimed to determine the role of DC

Abstract:

Argulus foliaceus (Linnaeus, 1758) is a member of the branchiuran family Argulidae and has a worldwide distribution, causing major economic impacts for freshwater aquacultured fish species worldwide. In the UK, it has economic impacts for both aquaculture and sports fishing industries. Previous studies observed haemorrhagic and inflammatory responses after Argulus infection, which has been taken to support the idea that the parasite secretes chemicals during the feeding process to assist with the ingestion of blood and epithelial tissue. The present study suggests that the blood-feeding ectopa

Abstract:

Ma thèse s'inscrit dans l'étude des modifications du globule rouge humain induites par P. falciparum. Ces modifications qui représentent une remarquable adaptation du parasite à un environnement plus complexe qu'il n'y paraît au premier abord et expliquent sa persistance chez l'Homme sont détaillées dans une revue et un chapitre de livre dont je suis co-auteur. Mes travaux de recherche ont porté sur la caractérisation fonctionnelle des structures de Maurer, un compartiment membranaire exporté par le parasite dans le globule rouge parasitaire et directement lié à la physiopathologie du paludism

Abstract:

Chronic stress can result in elevated circulating levels of glucocorticoid hormones in vertebrates, which can affect their stress response, their immune function, and eventually their fitness. I tested the effect of chronic corticosterone (CORT) elevation on the acute stress responsiveness, immune function, and body condition of free-living painted turtles (Chrysemys picta) in Gatineau Park, using slow-release exogenous CORT administration. While Silastic implants did not predictably elevate circulating CORT concentrations in painted turtles, injections of CORT-laden cocoa butter kept circulat
