Abstract:

Expression of acquired immunity to gastrointestinal parasites usually breaks down during the periparturient period, which is characterised by an increased worm burden and nematode egg excretion. It is believed that this breakdown of immunity may have a nutritional basis, and that by reducing nutrient scarcity the lactating animal will be able to reduce her worm burden. Therefore, the aim of this thesis was to carry out four experiments to investigate the potential use of metabolisable protein as an alternative way to control gastrointestinal parasitism in periparturient animals.

Abstract:

Brood parasitic birds lay eggs amongst the clutches of other species, which then assume all costs of parental care on their behalf. This thesis addresses several puzzles of avian brood parasitism, using field studies and theoretical modelling of the generalist parasite, the shiny cowbird (Molothrus bonariensis) and select hosts in Argentina. Key findings and conclusions were: • High parasitism intensity in a host population can result in a cost to hosts of removing parasite eggs from their clutches, and so help to maintain host’s acceptance of parasite eggs in evolutionary equilibrium.

Abstract:

Vertebrate males frequently carry higher numbers of parasites than females. This bias in parasite loads could be a consequence of sexual selection. Grouping species are also assumed to be afflicted with larger numbers of parasites than solitary animals and associated costs of this parasitism could vary with group size or structure. I examined sex-biased parasitism and the influence of group size on parasite loads in Cape ground squirrels (Xerus inauris), a highly social species that occurs in the arid regions of southern Africa. Males carried three times as many ectoparasites as females, but f

Abstract:

The pathogenic fungi Cryptococcus neoformans and Cryptococcus gattii are two of the main causes of life-threatening meningoencephalitis in immunocompromised and immunocompetent individuals respectively. Following inhalation, cryptococci are engulfed by phagocytic cells in the lung and previous studies by our group and others have demonstrated that they are then able to survive inside these cells (especially macrophages), thus acting as intracellular parasites. This intracellular phase is thought to underlie the ability of the pathogens to remain latent for long periods of time within infected

Abstract:

Parasites are important drivers of ecological and evolutionary processes in their hosts. However, hosts often differ in how they are affected by parasitism, which can be important in how parasite effects on individuals scale up to the population level. Hosts may differ intrinsically in their susceptibility to parasitism, and extrinsic factors may impose constraints on how hosts allocate resources between immunity, maintenance and reproduction, thereby further affecting their ability to cope with infection. These extrinsic factors include the host’s ecological environment, for example food avai

Cyst nematodes in the genus Heterodera are sedentary endoparasites that induce elaborate feeding cells within host roots by secreting proteins produced within nematode esophageal glands into plant cells.

Homologs of four parasitism genes initially isolated from Heterodera glycines, including Hg4F01 (annexin-like protein), HgSYV46 (CLAVATA3-like plant peptide mimic), Hg4E02 and Hg5D08 (novel proteins with putative host nuclear localization) were isolated from

Of the four most diverse insect orders, the Lepidoptera contain remarkably few predatory and/or parasitic taxa, and while species with carnivorous life histories have evolved independently numerous times in moths and butterflies, this has rarely led to diversification. As a rule, aphytophagous taxa seem prone to extinction. In this dissertation, I explore the ecological and evolutionary consequences of entomophagy in the butterfly family Lycaenidae using several approaches: natural history observation, phylogenetics, population genetics and stable isotope chemistry.

Many studies of evolution adopt a unifactorial approach, where a single causal force appearing to account for a majority of the phenotypic variation becomes the focal point of investigation. However, it seems certain that no single force acts to the complete exclusion of other forces, and so multi-factorial studies can make a crucial contribution to our understanding of the evolution of phenotypic variation. In the Trinidadian guppy system, natural selection acting via predation has long been recognized as playing an important role in shaping trait variation. However, other environmental facto

Many bumblebee species are suffering from the effects of habitat fragmentation and population isolation. In some cases, populations have lost genetic diversity due to genetic drift and it is possible they are now at heightened risk of extinction. Inbreeding may be particularly costly to bumblebees because, as Hymenoptera, their complementary sex determination system can lead to the production of sterile or inviable diploid males. However, little is known about the effect that diploid male production has on bumblebee colony fitness. Here, the consequences of brother-sister mating in the bumbleb

A presente pesquisa teve como objetivo registrar o parasitismo em A. pyrrhogularis procedentes de quatro áreas do Ceará. É apresentado um inventário das espécies de helmintos, o qual foi constituído de nove taxa: Oo

Abstract:

The natural resistance associated macrophage protein gene (<I>Nramp1</I>) influences susceptibility to several intracellular infections. To investigate the mechanism of this effect, congenic <I>Nramp1</I> wild type (infection resistant) and mutant (infection susceptible) mice were infected with <I>Leishmania donovani</I>. The <I>Nramp1</I> mutant mice developed more severe infection. Quantitative RT-PCR and fluorescence microscopy demonstrated that the mutant mice had attenuated hepatic chemokine and pro-inflammatory cytokine innate immune responses, reduced hepatic cellular infiltrate, reduce

Abstract:

Every aspect of an individual’s behaviour is, to some extent, mediated by parasite exposure. Potential hosts can, for example, initiate evasive behaviours towards infected conspecifics to reduce infection risk. If infected, individuals may exhibit adaptive behavioural responses aimed at reducing pathological symptoms. In addition to infection-mediated behavioural modifications, hosts behaviourally adapt to the environment in which they reside. Disentangling the effects of parasitism from environmental variables on host behaviour can be challenging. In a series of self-contained experiments, th

Celem rozprawy Pasożyt i pasożytnictwo w wiktoriańskiej nauce i literaturze jest ukazanie, w jaki sposób nauka (rozumiana tu jako nauka biologiczna) i literatura (w rozumieniu prozy) okresu wiktoriańskiego wzajemnie na siebie wpływały. Te powiązania są analizowane na przykładzie pasożyta i pasożytnictwa, które to zjawiska rozpatrywane są na czterech płaszczyznach: biologicznej, ekologicznej, zwyczajowej i literackiej. Zawarte w rozprawie teksty literackie i naukowe traktowane są równorzędnie: jako fikcyjne i niefikcyjne opowieści (stories). Rozdział I ukazuje, jak zależności pomiędzy na

Abstract:

Salmonella est un pathogène intracellulaire dont la virulence dépend de la fonction de deux systèmes de sécrétion du type trois (T3SS). Les T3SSs sont responsables pour la transduction de protéines effectrices dans le cytoplasme de la cellule hôte afin d'initier l'invasion de la cellule et de former la vie intracellulaire de Salmonella. Plusieurs effecteurs forment la SCV et induisent un réseau de tubules qui est impliqué dans la stabilisation de la SCV. Il consiste de trois différents genres de tubules. Nous avons pu montrer que les protéines effectrices SseF et SseG sont responsables pour la
