Abstract (sommario):

Candida pathogenic yeasts represent a global healthcare problem. They comprise phylogenetically diverse species, including newly emerged pathogens. How human-Candida interactions vary across species, and what processes underlie the emergence of novel pathogens are poorly understood. Current thesis addresses these issues using comparative transcriptomics and bioinformatics. We established the global patterns of host-pathogen interactions between human host and the main Candida species, providing novel mechanistic insights into their interplay. We also explored lncRNAs of these pathogens, assess

Abstract (sommario):

Aptamers are biomolecular ligands composed of nucleic acids. They can be selected to bind specifically to a range of target molecules and subsequently exploited in a fashion analogous to more traditional biomolecules such as antibodies. In this study a method for selecting new aptamers which specifically bind whole live bacterial cells is described. A non-pathogenic strain of Escherichia coli K12 was used to develop the method. A DNA library containing 100 bases long random nucleotide sequences was produced and the aptamer selection process was repeated nine times. An enzyme-linked technique w

Abstract (sommario):

Cellular and extracellular host-pathogen interactions are important in the progression of infection. Extracellular survival and growth can be significant for pathogen dissemination. Equally, intracellular pathways, such as autophagy, can be employed in host cell defence. Autophagy is a cellular self-degradation process that recycles cellular components through lysosomal degradation. Primarily for regulating starvation and housekeeping pathways, autophagy is also important for degradation of invading intracellular pathogens. Selective autophagy receptors can also target pathogens for autophagic

Abstract (sommario):

Candida species are among the most important fungal pathogens. Although Candida albicans is the most common cause of Candida infections, many other Candida species have emerged as pathogens. How pathogenicity is evolutionary acquired is unknown, but previous studies point to a role of hybridization in its development. This thesis studied the genomic features of Candida pathogens, with a special focus on hybrids and their evolution. Specifically, it asked the questions of how spread are hybrids among Candida species, and what are the processes that drive the evolution of their genomes. To this

It is a known fact that the whole agriculture system is suffering from the diseases caused by plant pathogens, affecting negatively the crop yield production, food security, biodiversity, agricultural ecosystem and hence agricultural economy. In many countries, the containment strategies of plant pathogens are still depending on chemical pesticides that cause adverse effects in the long term. According to the implementations reinforced by European council 2009/128/EC, biocontrol strategies are considered as the most profound and integrated approach for sustainable disease management.

Abstract (sommario):

The ability to mount an efficient immune response should be an important life-history trait as parasitism can impact upon an individual's fecundity and survival prospects, and hence its fitness. However, immune function is likely to be costly as resources must be divided between many important traits. Whilst many studies have examined host resistance to particular parasite types, fewer have considered general immune responses. Studies that have considered general immune responses tend to do so in vertebrate models. However, the complexity of the vertebrate immune system makes the examination o

Abstract (sommario):

Many microbial pathogens are able to evade killing by phagocytes of the innate immune system. This thesis focuses on two pathogens: the fungal pathogen \(Cryptococcus\) \(neoformans\) and the bacterial pathogen \(Streptococcus\) \(agalactiae\). \(C\). \(neoformans\) causes severe cryptococcal meningitis in mostly immunocompromised hosts, such as those with HIV infection. In contrast, \(S\). \(agalactiae\) is the leading cause of neonatal sepsis and meningitis.

Populations of many bacterial pathogens are structured into discrete strains despite frequent genetic exchange. Although insights from several studies suggest that different selection pressures operate in different areas of the genome, few theoretical and conceptual frameworks of bacterial population structure examine the effects of distinct competitive processes acting on different loci in the genome, and fewer still have considered the metabolic genes despite their increasingly-recognised importance in virulence.

Abstract (sommario):

Infections with multi-drug resistant bacteria are an urgent health security threat and bacteriocins such as the subclass of lantibiotics represent a promising alternative source to traditional antibiotics. The gut intestinal tract ecosystem has a complex set of bacteria with a huge bacteriogenic potential and it can be explored as a source for new lantibiotic peptides. Using a genome mining approach, a clos gene cluster that has the potential to encode for novel lantibiotics was previously discovered in a strain of Blautia isolated from the human gut. This clos operon may encode two nisin-like

Abstract (sommario):

Bivalve molluscs are an important food source for living beings, humans included. They are obligated filter feeders, that feed on microalgae, bacteria and organic particles present in the aquatic environment. Accordingly, they could accumulate chemical compounds, marine biotoxins, bacteria and viruses, including human and animal pathogens (Molloy et al., 2013; Serratore et al., 2014), influencing the epidemiology of animal and human infectious diseases (Skär & Mortensen, 2007). This topic has been long investigated for human pathogens. On the other hand, poor studies were available for finfis
