The influence of sublethal concentrations of two sanitizers, liquid iodophor and liquid hypochlorite (LH), on the growth rates and toxicity of food-borne pathogenic Escherichia coli strains grown in the presence of spoilage yeast Zygosaccharomyces bailii was assessed. When grown in combination with Z. bailii both E. coli O113 and E. coli O26 exhibited slower growth rates, except when E. coli O1...

Despite advances in care, infection in total joint arthroplasty remains a serious problem that has yet to be solved. Reported infection rates range from <0.5% in highly specialized centers to a high of 2% as reported at a national level. The epidemiology of total joint arthroplasty remains challenging because of the relatively low, but significant, incidence of infection. Still, there are varia...

A putative link between Salmonella persistence in the agricultural sector and resistance to disinfectants has been sparsely investigated. Therefore, minimum inhibitory concentration (MIC) tests against five disinfectants commonly used in poultry premises (formaldehyde, glutaraldehyde/benzalkonium chloride compound, oxidising compound, tar oil phenol, iodophor) were performed on 286 Salmonella i...

Fifteen volunteers lay supine for 3 hours in an empty operating theatre. Five rectangular areas were marked on the abdomen of each volunteer and a different antiseptic preparation was applied to four of the five areas. These were: 3 min painting with chlorhexidine in 70 per cent alcohol; 3 min painting with povidoneiodine in 70 percent alcohol; I min painting with 70 percent isopropyl alcohol a...

The recent report of poor iodine status in the UK is a wake-up call to health authorities in industrialized countries who have been slow to grasp that iodine deficiency (ID) is not confined to developing countries. Australia, New Zealand, Belgium, Norway and now the UK are all mildly iodine deficient. In the US, iodine intakes have fallen, and it is uncertain whether status is adequate in pregn...

BACKGROUND Although rare, infectious sequelae of epidural analgesia can occur. A recently marketed antiseptic solution (DuraPrep) which contains an iodophor in isopropyl alcohol, may provide enhanced and longer-lasting antimicrobial activity and thus be useful in the obstetric setting. The purpose of this study was to evaluate the antisepsis achieved with DuraPrep compared with povidone iodine ...

Iodine deficiency is not only a problem in developing regions; it also affects many industrialised countries. Globally, two billion individuals have an insufficient iodine intake, and approximately 50% of continental Europe remains mildly iodine deficient. Iodine intakes in other industrialised countries, including the USA and Australia, have fallen in recent years. Iodine deficiency has reappe...

A quantitative assay using a neutralization medium was developed to evaluate fungicidal activity of disinfectants. Concentrated Dey-Engley neutralizing broth was used in this study and was demonstrated to inactivate various chemical agents within 5 min when disinfectant concentrations were reduced to specific levels. Addition of this Dey-Engley broth to test tubes containing fungal cells and di...

Because of the increasing recognition that Campylobacter jejuni is an important enteric pathogen of humans, we studied the effects of widely used disinfectants on the viability of this organism. At an inoculum size of 10(3) to 10(4) CFU/ml, 1.25 mg of hypochlorite per liter killed three strains within 1 min. At an inoculum size of 10(6) to 10(7) CFU/ml, 5 mg of hypochlorite per liter killed thr...
