Summary
Fungal infections represent a major health burden, with loss of lives that parallels malaria. Only a handful of antifungal therapeutics is available, and mortality remains very high (30% or more). By using molecular biology approaches and animal infection models, this project aims to characterize a new class of promising antifungal drug targets in the major human fungal pathogen Candida albicans. The outcomes will provide the knowledge foundation for future antifungal drug discovery.
An Investigation Into Mitochondrial Dynamics In The Human Pathogen Candida Albicans

Summary
Our goal is to find new therapies to treat infections with Candida albicans, a major human pathogen that causes highly fatal hospital-associated disease. We have identified the mitochondrion, the cellular powerhouse, as a promising target for the development of new anti-candida drugs. We will use innovative imaging and molecular approaches, together with experimental animal infection models to understand how mitochondria could be inhibited to treat life-threatening infections with Candida.
An Investigation Into Pathogen-specific Factors Required For Drug-resistance And Viability Of Candida Albicans

Funding Amount
$337,614.00
Summary
We identified proteins required for growth and drug resistance of the fungus Candida albicans, a major hospital-acquired human pathogen. Candida infections target the immunocompromised and mortality is huge (?30-50%). We will use cell biology, genetics and biochemistry to characterise these proteins. Importantly, these factors are present in fungi, but absent from humans. Therefore our study will help development of new strategies for antifungal treatments.
Fungal Determinants And Host Cell Death Signals In Fatal Candida Infections

Summary
Fungal pathogens are a major burden in hospital settings as they evade the immune system and cause lethal sepsis. This project will determine the molecular factors utilized by the fungal pathogen Candida to kill host immune cells. We will investigate whether immune cell death contributes to the high fatality rate, commonly associated with systemic Candida infections, and whether this can be targeted by novel therapeutics.
Mechanisms Of Interaction And Therapeutic Strategies For Polymicrobial Biofilms

$607,231.00
Summary
A public health crisis is brewing with regard to hospital-acquired infections. The ability of bacterial and fungal organisms to attach and bind tightly to the surface of invasive medical devices is the root-cause of the majority of hospital-acquired infections. This research will study how bacteria and fungi interact in communities attached to medical devices, and devise strategies for their combined treatment.
Characterizing The Molecular Mechanisms Of Clinically Important Bacterial-fungal Interactions; The Potential To Uncover Novel Therapeutic Targets

Summary
In hospitals and in nature, diverse microbes, such as bacteria and fungi, often live in close proximity to each other. Their interactions can either be helpful or detrimental to one another, and such interactions are likely important for their ability to cause human disease. This proposal aims to study the mechanisms by which bacteria interact with fungi and by doing so, will identify important mechanisms of how microbes cause human illness and also uncover new targets for antibiotic development ....In hospitals and in nature, diverse microbes, such as bacteria and fungi, often live in close proximity to each other.

Targeting Acetohydroxyacid Synthase To Discover New Antifungal Agents.

Summary
Invasive fungal infections are increasingly being recognized as a major life threatening risk to hospitalized patients. The efficacy of the current medications is sub-optimal due to the emergence of resistance and the high dosage regimes that are required to treat these infections. We propose to develop a new class of antifungal agent that target an enzyme, acetohydroxyacid synthase, whose activity is required for the survival of pathogenic fungi in mammals.
