Associate Professor Anthony Kicic is working alongside local Indigenous communities to search land and water for naturally occurring bacteriophages.
Pulmonary bacterial infections present a significant health risk to those with chronic respiratory diseases including cystic fibrosis and chronic-obstructive pulmonary disease. With the emergence of antimicrobial resistance, novel therapeutics are desperately needed to combat the emergence of resistant superbugs.
Aspergillus is increasingly associated with lung inflammation and mucus plugging in early cystic fibrosis disease during which conidia burden is low and strains appear to be highly diverse. It is unknown whether clinical Aspergillus strains vary in their capacity to induce epithelial inflammation and mucus production.
Persistent respiratory bacterial infections are a clinical burden in several chronic inflammatory airway diseases and are often associated with neutrophil infiltration into the lungs. Following recruitment, dysregulated neutrophil effector functions such as increased granule release and formation of neutrophil extracellular traps (NETs) result in damage to airway tissue, contributing to the progression of lung disease.
Bacteriophage (phage) propagation has traditionally relied on bacterial culture media containing animal-derived ingredients; however, safety concerns with animal-derived materials for production of phages for therapeutic use limit their acceptability. We compared animal-free and traditional media formulations, and evaluated effects on phage yield, bactericidal activity, and genomic characteristics, hypothesizing no significant differences would be observed.
Antimicrobial resistance is a current global health crisis, and the increasing emergence of multidrug resistant infections has led to the resurgent interest in bacteriophages as an alternative treatment.
Respiratory disease is a leading cause of hospitalisations in children with cerebral palsy (CP). Over 40% of individuals with CP are born preterm; however, the relationship between prematurity, CP and respiratory disease is unknown.
Neuromuscular disorders include many rare conditions, such as Duchenne Muscular Dystrophy and Spinal Muscular Atrophy, that adversely impact respiratory health.
Flare-ups of asthma are usually brought on by respiratory infections, such as the common cold, and are one of the most common reasons for a child to miss school or require emergency care.
The Wal-yan Respiratory Research Centre is a global epicentre for paediatric respiratory research, informing clinical practice and driving a new research agenda for childhood lung health.
