Cough-generated aerosols of Pseudomonas aeruginosa and other Gram-negative bacteria from patients with cystic fibrosis
BACKGROUND Pseudomonas aeruginosa is the most common bacterial pathogen in patients with cystic fibrosis (CF). Current infection control guidelines aim to prevent transmission via contact and respiratory droplet routes and do not consider the possibility of airborne transmission. It was hypothesised that subjects with CF produce viable respirable bacterial aerosols with coughing. METHODS A cr...
متن کاملViability of Pseudomonas aeruginosa in cough aerosols generated by persons with cystic fibrosis
BACKGROUND Person-to-person transmission of respiratory pathogens, including Pseudomonas aeruginosa, is a challenge facing many cystic fibrosis (CF) centres. Viable P aeruginosa are contained in aerosols produced during coughing, raising the possibility of airborne transmission. METHODS Using purpose-built equipment, we measured viable P aeruginosa in cough aerosols at 1, 2 and 4 m from the s...
متن کاملAntibiotic Susceptibility of Pseudomonas Aeruginosa Isolated from Cystic Fibrosis Patients
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
متن کاملIsolation and Genetic Fingerprinting of Pseudomonas aeruginosa from Iranian Patients with Cystic Fibrosis Using RAPD-PCR
Sixty four Iranian patients with cystic fibrosis (CF) were studied for colonization with Pseudomonasaeruginosa. The patient’s age ranged between 2 months to 18 years old. Twenty one patients werecolonized, 15 with non-mucoid and 6 with mucoid strains of P. aeruginosa. The colonization rateincreased with age and the mucoid phenotype was only recovered from the older patients. A...
متن کاملAbility of device to collect bacteria from cough aerosols generated by adults with cystic fibrosis
Background: Identifying lung pathogens and acute spikes in lung counts remain a challenge in the treatment of patients with cystic fibrosis (CF). Bacteria from the deep lung may be sampled from aerosols produced during coughing. Methods: A new device was used to collect and measure bacteria levels from cough aerosols of patients with CF. Sputum and oral specimens were also collected and measure...
