The author presents details on the cleaning and disinfection of specialised farrowing accommodation within an intensive pig unit. Procedures are described for use in two quite different sets of circumstances, as follows: in the event of the occurrence of one of the major notifiable epizootic diseases; routine cleaning and disinfection as part of normal management procedures. In the former case,...

ASBSTRACT Disinfection should be required for all skin penetrative procedures including parenteral administration of vaccines. This review analyses medically attended infectious events following parenteral vaccination in terms of their microbiological aetiology and pathogenesis. Like 'clean' surgical site infections, the major pathogens responsible for these events were Staphylococcal species, ...

Previous studies modeled NDMA formation during chlorine disinfection as arising from the oxidation of an unsymmetrical dimethylhydrazine intermediate formed from the reaction of monochloramine and dimethylamine. However, chlorination of wastewater effluents indicated that this mechanism could not account for a significant portion of the observed NDMA formation. Laboratory studies indicated that...

background: it is thought that the transmission of hepatitis b virus (hbv) through the endoscopic procedures is a very rare event. the aim of this study is to evaluate the effect of the standard disinfection procedure of the endoscopes and accessories versus conventional disinfection in the transmission of hbv. materials and methods: a prospective survey, comprising 520 consecutive upper gastro...

Bacterial contamination of gastrointestinal fibre-endoscopes is a potential source of clinically significant infection. Aqueous 2% alkaline glutaraldehyde adequately disinfects fibre-endoscopes but may cause serious sensitivity reactions among endoscopy staff. A new 'closed-system' disinfecting apparatus is described that disinfects with glutaraldehyde for 30 minutes before an endoscopy session...

Antibiotic resistance is a growing problem in the hospital setting. Organisms that cause hospital-acquired infections are generally highly resistant, requiring expensive antibiotics and further hospitalization. As a result, many owners of infected pets choose euthanasia. Appropriate hospital disinfection and staff hygiene practices can prevent such infections by reducing the pathogen load in a ...

BACKGROUND: The practice of using disinfectants to safeguard against the acute effects of waterborne disease are well established and regulated in the United States. New regulations designed to minimize the risks associated with chronic exposure to disinfection by-products (DBPs), however, are changing the current regulatory framework. Changes in disinfection practices meant to comply with thes...

Ozone is a powerful drinking water disinfectant that is effective in treating chlorine resistant organisms, such as Cryptosporidia. For bottled water, ozonation is generally preferred over other available disinfection treatment methods because it does not leave a taste or residual disinfectant, due to ozone’s short lifetime. However, ozonation of drinking water containing bromide can result in ...
