Inactivation of norovirus by chlorine disinfection of water.
In an effort to validate previous research suggesting remarkable resistance of norovirus to free chlorine disinfection, we characterized the disinfection response of purified and dispersed Norwalk virus (NV) by bench-scale free chlorine disinfection using RT-PCR for virus assays. The inactivation of NV by two doses of free chlorine (1 and 5mg/L) at pH 6 and 5 degrees C based on two RT-PCR assay...
متن کاملChlorine in water disinfection
Disinfection of drinking-water is one of the main achievements of our time in the protection of public health. The use of chlorine for the destruction of microbiological pathogens is essential to protect the public from outbreaks of waterborne disease. Chlorine, as well as other disinfectants, produces a variety of chemical by-products. The risk from the presence of microbial pathogens in drink...
متن کاملTomato Seed Disinfection with Chlorine
Chlorine is a commonly used disinfectant for tomato seed contaminated with the bacterial pathogens causing canker, spot, and speck diseases. Previous research has attempted to determine chlorine effectiveness by testing for the presence of the pathogen after treatment of infected seed lots. Even with the most advanced techniques, the accuracy of these methods is questionable, and can underestim...
متن کاملCharacterization of ozone disinfection of murine norovirus.
Despite the importance of human noroviruses (NoVs) in public health, little information concerning the effectiveness of ozone against NoVs is available. We determined the efficacy of ozone disinfection using murine norovirus (MNV) as a surrogate of human NoV. MNV in ozone demand-free buffer was exposed to a predetermined dose of ozone at two different pHs and temperatures. The virus remaining i...
متن کاملThe synergistic effect of Escherichia coli inactivation by sequential disinfection with low level chlorine dioxide followed by free chlorine.
To the best of our knowledge, there was little information available on pathogen removal using low level disinfectant followed by free chlorine in sequential disinfection (SD). This study investigated Escherichia coli inactivation by four types of disinfection: single step disinfection (SSD), SD, traditional sequential disinfection (TSD) and mixed disinfectant disinfection (MDD). Results indica...
