The Association of Official Analytical Chemists bacterial use-dilution test for evaluating liquid surface disinfectants was modified to determine the efficacy of three common environmental germicide compounds against representatives of four virus groups. Modifications were made to conform to the Environmental Protection Agency guidelines on virucidal testing procedures. Alterations included: th...

Haematologica vol. 84(11):November 1999 nation of blood products. In this case, the transmission of a strain of P. rettgeri originated from the same donor, resulted in the death of two patients. Although Gram negative bacilli have been described as contaminants of blood products, we have not found any references concerning P. rettgeri.2,3 In the present case, the donor could not be studied, but...

Vulvovaginal candidasis is a significant gynaecological infection, which causes extreme discomfort, such as vulvovaginal itching. Using modified agar well-diffusion method, this study therefore, investigates in vitro inhibitory / cleansing potentials of soaps, germicides and disinfectants on vulvovaginal Candida species, especially with regards to vulvovaginal itching. Crusader oil (100%), Meri...

C hemical disinfection of surfaces and instruments is an important aspect of infection control as routinely practised in dental units and elsewhere. The timing and method of chemical disinfection, the factors affecting the efficacy of germicides and the hazards posed by their use are important considerations in selecting disinfectants. The terminology used for such chemicals is often confusing,...

We propose a tool for a rapid high-resolution detection of calcium ions which can be used in parallel with other techniques. We have applied a new approach by  photo-oxidation of diaminobenzidine in presence of the emission of an excited fluorochrome specific for calcium detection. This method combines the selectivity of available fluorophores to the high spatial resolution offered by transmiss...

A variety of chemicals are used in medical imaging as developer and fixer ingredients, germicides, and cleaning agents. Glutaraldehyde, a potent sensitizer, may cause occupational skin and respiratory diseases in exposed individuals. Poor ventilation, unsafe practices, and lack of hazard recognition may contribute to occupational asthma and other respiratory disease in susceptible medical imagi...
