Understanding The Development And Spread Of Pan Resistance In Acinetobacter Baumannii

Funding Amount
$2,339,215.00
Summary
Resistance to all antibiotics available for treatment of bacterial infections is a cause for global concern (Word Health Organization, US Centres for Disease Control) as it also compromises therapies relying on antibiotics such as transplantation and cancer chemotherapy. Extensively antibiotic resistant Acinetobacter baumannii, mainly causes hospital-acquired infections. This project will seek to track different types of these bacteria as they repeatedly spread around the world.
Molecular Epidemiology Of Antibiotic Resistant Salmonella Enterica Strains Causing Human Disease

Summary
Salmonella infections are responsible for a substantial proportion of reported food poisoning cases caused by bacteria and many of these infections are due to antibiotic resistant strains. Infections caused by antibiotic resistant organisms are hard to treat and generally more severe, of longer duration, and result in longer hospital stays. These strains are mostly acquired from foods, e.g. meats, dairy products, poultry, eggs, and other contaminated food products but can also be derived from ot ....Salmonella infections are responsible for a substantial proportion of reported food poisoning cases caused by bacteria and many of these infections are due to antibiotic resistant strains. Infections caused by antibiotic resistant organisms are hard to treat and generally more severe, of longer duration, and result in longer hospital stays. These strains are mostly acquired from foods, e.g. meats, dairy products, poultry, eggs, and other contaminated food products but can also be derived from other sources. Salmonella strains harboured by food-producing animals are the source of most of the food contamination.Tracing the source of individual resistant strains is essential for eradication and as there are many Salmonella types, some of which are found associated only with specific animals or birds, accurate identification is needed. The proposed work will make this process more accurate by using molecular techniques to unequivocally establish suspected connections and reveal further ones that are difficult to discern using current data and methods. This should decrease the number of infections due to resistant strains.Read moreRead less
Antibiotic resistance increases mortality and costs in the Intensive Care Unit (ICU), but the impact of antibiotic therapy has not been adequately studied. We propose to characterise the behaviour of key elements of the bacterial microflora (resistant bacteria and major resistance genes) in response to antibiotics. We have developed new rapid diagnostics to harness these data and this proposal has the potential to greatly improve diagnostic speed and accuracy and thus clinical outcomes.
Plasmodium Knowlesi As A Genetic Model For Plasmodium Vivax Drug Resistance

Summary
Two different Plasmodium parasites cause the majority of malaria worldwide. However, one type, P. vivax, is unable to be cultured in the laboratory and therefore has been poorly studied. Drug resistance has been observed but the underlying causes are poorly understood. We propose to use a closely related parasite, P. knowlesi, as a model to understand drug resistance mechanisms. This knowledge will be used to follow resistance in the field and direct policy of the most appropriate treatment.
Novel Membrane-targeted Antibiotics Against Drug-resistant Gram-positive Bacterial Infections
Funder
National Health and Medical Research Council
Funding Amount
$1,351,496.00
Summary
This project aims to develop a best in class antibiotic, Vancapticin, with superior efficacy, broader spectra of action and improved therapeutic index than existing therapies for Gram-positive (G+ve) bacterial infections. The research team has identified lead candidates that offer equivalent &/or superior potency, efficacy & pharmacokinetic profiles compared to several clinical comparators. NHMRC Development funding is required to select a candidate for an Investigative New Drug application.
A New Mechanism For Transposition Of Antibiotic Resistance Genes
Funder
National Health and Medical Research Council
Funding Amount
$501,839.00
Summary
Understanding how antibiotic resistance genes are acquired by bacteria is important if we are to understand how bacteria become resistant in so many antibiotics, limiting treatment options. This project will investigate the way a family of insertion sequences captures and then moves resistance genes. This mechanism contributes to resistance in many bacterial pathogens including ones that are resistant to many different antibiotics.
Antimicrobial Stewardship - Establishing Effective Programs For Australian Hospitals
Funder
National Health and Medical Research Council
Funding Amount
$1,232,361.00
Summary
This project will examine strategies to improve the use of antimicrobial drugs in Australian hospitals. It will evaluate the impact of antimicrobial stewardship programs on antibiotic prescribing practices in Victorian tertiary hospitals and determine the organisational factors associated with success. It will also examine the needs, and establish models for antimicrobial stewardship beyond the tertiary hospital setting, in private hospitals, small metropolitan and rural hospitals.
Potent Antibiotics Against Drug-resistant Tuberculosis

Funding Amount
$531,410.00
Summary
Tuberculosis (TB) is a significant killer and caused 1.7 million deaths in 2009. The disease affects all countries, including Australia, in which the incidence in the indigenous population is 14 times higher than that in the non-indigenous population. We will develop a new anti-TB drug that can replace or enhance the current drugs that are not effective against drug resistant TB.
Structure-based Design Of Novel Therapeutics For Multi-drug Resistant Neisseria Gonorrhoeae
Funder
National Health and Medical Research Council
Funding Amount
$669,148.00
Summary
Multiple drug resistance (MDR) in bacteria represents one of the most intractable problems facing modern medicine. The recent superbug, MDR-Neisseria gonorrhoeae (MDR-Ng), causes the sexually transmitted infection gonorrhoeae. A multi disciplinary team with expertise in structural biology, medicinal chemistry and bacteriology will establish a comprehensive knowledge base aimed at developing new antibiotics to treat MDR-Ng by targeting a bacterial protein virulence factor.
