Activity of Hospital #Disinfectants against Vegetative Cells and Spores of #Clostridioides difficile Embedded in Biofilms
Clostridioides difficile spores can survive in the environment either in mono- or mixed-species biofilms. However, no previous studies have investigated chemical disinfection of C. difficile spores embedded in biofilms.. C. difficile vegetative cells and spores were recovered from biofilms regardless the type of biofilm growth or biofilm growth time. No disinfectant was able to completely… Continue reading Activity of Hospital #Disinfectants against Vegetative Cells and Spores of #Clostridioides difficile Embedded in Biofilms
Association of Occupational Exposure to #Disinfectants With Incidence of Chronic Obstructive #Pulmonary Disease Among US Female Nurses
Exposure to disinfectants in health care workers has been associated with respiratory health outcomes, including asthma. Weekly use of disinfectants to clean surfaces only (16 786 [22.9%] of participants exposed) and to clean medical instruments (13 899 [19.0%] exposed) was associated with COPD incidence, with adjusted hazard ratios of 1.38 (95% CI, 1.13-1.68) for cleaning… Continue reading Association of Occupational Exposure to #Disinfectants With Incidence of Chronic Obstructive #Pulmonary Disease Among US Female Nurses
