Hitting bacteria with a Bam: Lectin-Like Antimicrobials as New Antibiotics. Antibiotic resistance in disease-causing bacteria is a rapidly growing problem, making the development of new antibiotics of critical importance. This project aims to develop naturally produced lectin-like protein antibiotics as novel antimicrobial agents. To achieve this, the project will produce an extensive library of these antibiotics and test them for potency and specificity. Using cutting-edge techniques, it will d ....Hitting bacteria with a Bam: Lectin-Like Antimicrobials as New Antibiotics. Antibiotic resistance in disease-causing bacteria is a rapidly growing problem, making the development of new antibiotics of critical importance. This project aims to develop naturally produced lectin-like protein antibiotics as novel antimicrobial agents. To achieve this, the project will produce an extensive library of these antibiotics and test them for potency and specificity. Using cutting-edge techniques, it will determine how these antibiotics kill cells on a molecular and cellular level. It is anticipated this research will create the tools and knowledge required to exploit lectin-like protein antibiotics to fight bacterial infection, which will lead to their use in the prevention of crop and livestock losses due to disease.Read moreRead less
Mechanism of secretion of large clostridial toxins . This project aims to investigate how the large clostridial toxins are secreted from important animal bacterial pathogens. This project expects to generate new knowledge about how bacteria interact with hosts through protein secretion, using a collaborative and interdisciplinary approach and cutting-edge techniques.

This project aims to investigate how the large clostridial toxins are secreted from important animal bacterial pathogens. This project expects to generate new knowledge about how bacteria interact with hosts through protein secretion, using a collaborative and interdisciplinary approach and cutting-edge techniques. Expected outcomes of this project include building a deep understanding of the role of export machinery in toxin secretion from bacteria, and the identification of new systems by which this is achieved. This should provide significant benefits, such as gaining new insights into new bacterial protein export mechanisms, with the aim of identifying targets for future veterinary disease interventions or biotechnological applications.Read moreRead less
How bacteria form resistant aggregates and biofilms. This research aims to use interdisciplinary approaches to advance fundamental knowledge on bacterial aggregates and biofilms. These bacterial clusters are a significant problem as they have extraordinary resistance to disinfectants and antibiotics, and currently no effective methods are available to disrupt them. The expected outcomes of this project are to dissect how autotransporters, the most common group of bacterial cell-surface proteins, ....How bacteria form resistant aggregates and biofilms. This research aims to use interdisciplinary approaches to advance fundamental knowledge on bacterial aggregates and biofilms. These bacterial clusters are a significant problem as they have extraordinary resistance to disinfectants and antibiotics, and currently no effective methods are available to disrupt them. The expected outcomes of this project are to dissect how autotransporters, the most common group of bacterial cell-surface proteins, promote aggregation and biofilm formation, and to develop inhibitors that prevent the formation of these damaging bacterial clusters. Ultimately, this new knowledge will help address the increasing economic and social burden of industrial, environmental and biomedical biofilms.Read moreRead less
Autotransporter assembly: new insights and biotechnological potential. The objective of this project is to improve our understanding of a fundamental biological problem: how autotransporters are assembled into cellular membranes. Autotransporters are a large family of bacterial proteins that play key roles in the pathogenesis of several infectious diseases. Currently, the precise mechanism by which disease-causing molecules are assembled into the outer membranes of bacteria and mitochondria is p ....Autotransporter assembly: new insights and biotechnological potential. The objective of this project is to improve our understanding of a fundamental biological problem: how autotransporters are assembled into cellular membranes. Autotransporters are a large family of bacterial proteins that play key roles in the pathogenesis of several infectious diseases. Currently, the precise mechanism by which disease-causing molecules are assembled into the outer membranes of bacteria and mitochondria is poorly understood. The knowledge that the project develops may inform future strategies aimed at the rational treatment of bacterial and mitochondrial diseases.Read moreRead less

Summary
Understanding nutritional interactions for targeted microbiome manipulation. This project aims to identify how microbial communities, known as microbiomes, can be effectively manipulated to the benefit of their host. Microbiome manipulation has been in the spotlight as a potential solution to maintain or improve the health of several hosts, from threatened coral species to livestock and humans, but the development of industry-scale strategies has been slow. This project proposes to chart the nut ....Understanding nutritional interactions for targeted microbiome manipulation. This project aims to identify how microbial communities, known as microbiomes, can be effectively manipulated to the benefit of their host. Microbiome manipulation has been in the spotlight as a potential solution to maintain or improve the health of several hosts, from threatened coral species to livestock and humans, but the development of industry-scale strategies has been slow. This project proposes to chart the nutritional interactions among microorganisms and to identify cascade effects of microbiome manipulation. This will generate fundamental knowledge on the biological processes underlying community stability and malleability, which will ultimately help engineering optimised microbiomes.Read moreRead less
Bacterial vesicles transport their bioactive cargo to the host nucleus. This project aims to investigate how bacterial membrane vesicles transport their cargo to the nucleus of cells and its impact on host cell functions. Bacteria use membrane vesicles as a means of communication with the host, but the full extent of their effects on host cells has yet to be fully elucidated. This project expects to generate new knowledge in the field using cutting-edge imaging and molecular biology approaches. ....Bacterial vesicles transport their bioactive cargo to the host nucleus.
