 Review the detection methods for organic chloramine described in the literature  Evaluate the formation of organic chloramine from reactions between extracellular polymer substances (EPS), a component of biofilms, and disinfectants (free chlorine or monochloramine)  Evaluate the formation of organic chloramine by reaction between heterotrophic plate count (HPC) bacteria (as planktonic bacte...

OBJECTIVE To evaluate the direct and transdentinal (indirect) agar diffusion antibacterial activity of different commercially available antibacterial dental gel formulations against Streptococcus mutans. MATERIALS AND METHODS The commercially available dental gel formulations were Corsodyl® (COG, 1% chlorhexidine), Cervitec® (CEG, 0.2% chlorhexidine + 0.2% sodium fluoride), Forever Bright® (F...

The purpose of this study was to investigate and compare the efficacy of various disinfectants on planktonic cells and biofilm cells of Listeria monocytogenes, Staphylococcus aureus and Escherichia coli. Numbers of viable biofilm cells decreased after treatment with all tested disinfectants (iodine, biguanide, quaternary ammonium compounds, peracetic acid and sodium hypochlorite). Sodium hypoch...

Cleaning and Disinfecting  The efficacy of most disinfectants against SVV is not clearly known.  Because vesicular diseases are clinically indistinguishable, disinfection protocols for FMDV should be followed even if SVV is suspected. This includes use of: sodium hydroxide, sodium carbonate, 0.2% citric acid, aldehydes, and oxidizing disinfectants including sodium hypochlorite.  Below are EP...

Spore-forming pathogenic bacteria, such as Clostridium difficile, are associated with nosocomial infection, leading to the increased use of sporicidal disinfectants, which impacts socioeconomic costs. However, C. difficile can be prevented using microorganisms such as Bacillus amyloliquefaciens, a prophylactic agent that has been proven to be effective against it in recent tests or it can be co...

Background Sensitivity to disinfectants plays a major role in the everyday lives of many people. Allergies, however, are far less common. Taking a detailed medical history and appropriate diagnostic allergy testing including skin test and if available in vitro tests are crucial in the professional workup of allergic responses to disinfectants. Here we present a case of a classic type-I reaction...

the effective use of disinfectants constitute an important factor in preventing hospital acquired infections. this study was undertaken to compare the effects of three newly introduced disinfectants in a number of tertiary care hospitals in India, namely superoxidized water (SOW) and two quaternary ammonium compounds (QACs), against the effects of 70% ethyl alcohol as one of the most commonly u...

Listeria monocytogenes is a food-borne human pathogen that causes listeriosis, a relatively rare infection with a high fatality rate. The regulation of virulence gene expression is influenced by several environmental factors, and the aim of the present study was to determine how disinfectants used routinely in the food industry affect the expression of different virulence genes in L. monocytoge...

The present study investigated the effectiveness of three different disinfectants: preparation H1 (two-component preparation based on hydrogen peroxide); Pedox (multi-component preparation based on peroxyacetic acid) and Savo hypochlorite preparation) against Malassezia pachydermatis. The antifungal activity of disinfectants was tested by quantitative suspension method according to STN EN 1650....
