Researchers at University of Akron Have Reported New Data on Cystic Fibrosis (Mathematical modelling of Pseudomonas aeruginosa biofilm growth and treatment in the cystic fibrosis lung)

By a News Reporter-Staff News Editor at Gastroenterology Week -- A new study on Lung Diseases and Conditions is now available. According to news reporting originating from Akron, Ohio, by NewsRx correspondents, research stated, "Lung failure due to chronic bacterial infection is the leading cause of death for patients with cystic fibrosis (CF). It is thought that the chronic nature of these infections is, in part, due to the increased tolerance and recalcitrant behaviour of bacteria growing as biofilms."

Our news editors obtained a quote from the research from the University of Akron, "Inhalation of silver carbene complex (SCC) antimicrobial, either encased in polymeric biodegradable particles or in aqueous form, has been proposed as a treatment. Through a coordinated experimental and mathematical modelling effort, we examine this proposed treatment of lung biofilms. Pseudomonas aeruginosa biofilms grown in a flow-cell apparatus irrigated with an artificial CF sputum medium are analysed as an in vitro model of CF lung infection. A 2D mathematical model of biofilm growth within the flow-cell is developed. Numerical simulations demonstrate that SCC inactivation by the environment is critical in aqueous SCC, but not SCC-polymer, based treatments."

According to the news editors, the research concluded: "Polymer particle degradation rate is shown to be an important parameter that can be chosen optimally, based on environmental conditions and bacterial susceptibility."
