Campylobacter is responsible for human bacterial enteritis and poultry meat is recognised as a primary source of infection. In slaughterhouses, cleaning and disinfection procedures are performed daily, and it has been suggested that disinfectant molecules might select for antibiotic resistant strains if shared targets or combined resistance mechanisms were involved. The aim of the study was to ...

Blankets may be disinfected in steam at subatmospheric pressures by temperatures below boiling point inside a suitably adapted autoclave chamber. The chamber and its contents are thoroughly evacuated of air so as to allow rapid heat penetration, and steam is admitted to a pressure of 10 in. Hg below atmospheric pressure, which corresponds to a temperature of 89 degrees C. Woollen blankets treat...

Several issues concerning endoscope reprocessing remain unresolved based on currently available data. Thus, further studies are required to confirm standard practices including safe endoscope shelf life, proper frequency of replacement of some accessories including water bottles and connecting tubes, and microbiological surveillance testing of endoscopes after reprocessing. The efficacy and cos...

Output water from dental unit waterlines (DUWLs) may be a potential source of infection for both dental healthcare staff and patients. This study compared the efficacy of different disinfection methods with regard to the water quality and the presence of biofilm in DUWLs. Five dental units operating in a public dental health care setting were selected. The control dental unit had no disinfectio...

Despite the low nutrient level and constant presence of secondary disinfectants, bacterial re-growth still occurs in drinking water distribution systems. The molecular mechanisms that starved bacteria use to survive low-level chlorine-based disinfectants are not well understood. The objective of this study is to investigate these molecular mechanisms at the protein level that prepare starved ce...

OBJECTIVE. Effective disinfection of hospital rooms after discharge of patients with Clostridium difficile infection (CDI) is necessary to prevent transmission. We evaluated the impact of sequential cleaning and disinfection interventions by culturing high-touch surfaces in CDI rooms after cleaning. DESIGN. Prospective intervention. SETTING. A Veterans Affairs hospital. INTERVENTIONS. During a ...

The influence of hexachlorophane disinfection on the bacterial hand flora of hospital personnel has been examined. Hexachlorophane effectively reduced the total number of bacteria and the staphylococcal carriage. Gram-negative bacilli were isolated from 18.8% of the personnel, and 13% of the carriers continued to carry Gram-negative bacilli for more than six months. The carrier rate was signifi...

BACKGROUND The aim of this study was to evaluate and compare microwave disinfection with chemical disinfection of dental gypsum casts. MATERIALS AND METHODS A total of 120 casts were prepared from a silicone mold using Type III dental stone. Of the 120 casts, 60 casts were contaminated with 1 ml suspension of Staphylococcus aureus and 60 casts were contaminated with 1 ml suspension of Pseudom...

The main transmission mechanism of COVID-19 is through close contact, aerosols, droplets, and fomites the disease in closed spaces. In this study, importance ventilation preventing expansion reviewed. total, 20 articles are obtained results show that has a crucial role indoor air environments. However, it should be used properly; otherwise, will cause further disease, as suggested for SARS. App...

Cleaning and disinfection of surfaces which have been in contact with animals, poultry or organic material is a vital element in controlling bacterial and viral diseases, and ensuring the wholesomeness and safety of foods. The thoroughness of pre-disinfection cleaning is the most important determinant of the efficacy of disinfection processes. Disinfectant users and officials responsible for th...
