Antibiotic resistant bacteria such as MRSA and pseudomonas aeruginosa are becoming more
prevalent. When a disinfectant containing benzalkonium chloride was applied to lab cultures of pseudomonas
aeruginosa, the microbe adapted to survive not only the disinfectant but also a common antibiotic.
"In principle this means that residue from incorrectly diluted disinfectants left on hospital surfaces could promote
the growth of antibiotic-resistant bacteria," said lead researcher Gerard Fleming of the National University of
Ireland in Galway. "What is more worrying is that bacteria seem to be able to adapt to resist antibiotics without
even being exposed to them."

benzalkonium chloride on the competitiveness of
Pseudomonas aeruginosa
grown in continuous culture.”

Prevalence of pediatric asthma in Canada is 13% and has increased over time.1 Asthma often begins early in childhood, and lifelong complications, including airway remodelling, can begin as early as the preschool years.2,3 As a result, focus on possible means of asthma prevention has increased.
Comprehensive longitudinal studies are important for understanding the complex risk factors, pathways, exposures and interactions that lead to the development and persistence of asthma. We aimed to examine associations between use of household cleaning products in early life and childhood respiratory and allergic disease using data from the Canadian Healthy Infant Longitudinal Development (CHILD) Cohort Study
