| This study investigated the effectiveness of detergent and aqueous solutions of 2% chlorhexidine digluconate in decontaminating gutta-percha cones (gpc) contaminated with bacteria, yeast, or bacterial spores. Gutta-percha cones were contaminated with 10(7)-10(8) colony-forming units per milliliter (cfu/ml) of the following test organisms: Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, or Candida albicans. Spores of Bacillus subtilis were also tested. Contaminated gpc were treated with the chlorhexidine solutions for 1, 5, 10, or 15 min. Each cone was then transferred to a tube containing saline and the micoorganisms were recovered after homogenization for cfu determination. Both detergent and aqueous chlorhexidine solutions were effective... |

| We compared the effectiveness of alcohol gel with that of the traditional hand-cleansing agents in removing clinical strains of Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa, and Candida albicans from artificially contaminated hands. The fingertips of 6 volunteers were contaminated with approximately 10(6) of microbial cells, and then were washed with: plain liquid soap, alcohol gel, 70% ethyl alcohol (by weight), 10% povidone-iodine liquid soap (PVP-I), and 4% chlorhexidine gluconate detergent. The experiments were performed using a Latin square statistical design, with six 6 x 5 randomized blocks, and the results were estimated by ANOVA. The products reduced from... |

| Biofilm bacterial infections are common in patients undergoing treatment with haemodialysis. This study involved 16 patients (7 males, 9 females; ages from 22 to 81 with an average age of 50) who had had a total of 25 temporary haemodialysis polyurethane catheter insertions into the subclavian vein (22 dual-lumen and 3 triple-lumen). The catheters remained in place from 3 to 91 days, on an average of 47 days. The reasons for catheter removal were: bad functioning (44%), suspicion of catheter-related infection (20%), availability of permanent access (16%), accidental removal (12%), signs and symptoms of infection at the site of catheter insertion (4%), and exogenous contamination (4%). Positive tip cultures were observed on seven of the catheters (28%),... |
