PURPOSE To evaluate the effectiveness of peracetic acid in the microbiological sterilisation of dental materials. METHODS Peracetic acid solution was evaluated at concentrations of 800, 1500 and 2500 ppm. At these concentrations, it was determined whether peracetic acid caused corrosion to dental instruments and induced cellular mutagenicity and cytotoxicity. In addition, the minimum inhibito...

Inherently, confined animal farming operations (CAFOs) and other intense fecal-rich environments are potential sources of groundwater contamination by enteric pathogens. The ubiquity of microbial matter poses unique technical challenges in addition to economic constraints when sampling wells in such environments. In this paper, we evaluate a groundwater sampling protocol that relies on extended...

OCCASIONAL infections in sites of venous cutdowns and an episode of fever in a patient following cardiac catheterization caused us to review the procedures used in this laboratory for preparation of catheterization equipment. Materials not susceptible to damage by wet heat (surgical instruments, syringes and needles, drapes) are sterilized in a steam autoclave. Polyethylene catheters, cuvette o...

background: to determine the efficacy of different antiseptic solutions (control group (i), antibiotic solution (ii), chlorhexidine 0.4% (iii), and povidone – iodine 10% (iv)) in sterilizing contaminated osteochondral plugs. methods: under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. a total of 200 osteochondral specimens ...
