Fungicidal activity of copper-sputtered flexible surfaces under dark and actinic light against azole-resistant Candida albicans and Candida glabrata

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

Candida spp. are able to survive on hospital surfaces and causes healthcare-associated infections (HCAIs). Since surface cleaning and disinfecting interventions are not totally effective to eliminate Candida spp., new approaches should be devised. Copper ( ...

Bactericidal activity and mechanism of action of copper-sputtered flexible surfaces against multidrug-resistant pathogens

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

Using direct current magnetron sputtering (DCMS), we generated flexible copper polyester surfaces (Cu-PES) and investigated their antimicrobial activity against a range of multidrug-resistant (MDR) pathogens including eight Gram-positive isolates (three me ...

In Vitro and In Vivo Effectiveness of an Innovative Silver-Copper Nanoparticle Coating of Catheters To Prevent Methicillin-Resistant Staphylococcus aureus Infection

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

In this study, silver/copper (Ag/Cu)-coated catheters were investigated for their efficacy in preventing methicillin-resistant Staphylococcus aureus (MRSA) infection in vitro and in vivo. Ag and Cu were sputtered (67/33% atomic ratio) on polyurethane cathe ...
