Investigation of antimicrobial activity and morphological properties of metal coated textile surfaces

The results of investigation antimicrobial and surface properties of the textiles metal coated by means of magnetron or the cleaning-deposition system, which is based on sequentially arranged DC anode layer accelerator and hollow cathode, are presented. The antimicrobial properties against bacteria E. coli and S. aureus of cotton and polyester/cotton textiles coated by Cu, Ti and Ag with the use of two different systems were examined and compared.Представлены результаты исследования антимикробных и поверхностных свойств тканей с металлическими напылениями, созданными при помощи магнетрона или чистяще-распылительного устройства на базе последовательно расположенных ускорителя с анодным слоем и полого катода. Определены и сопоставлены антимикробные свойства тканей из хлопка и смеси хлопок/полиэстер с напылениями из Cu, Ti и Ag, созданными с использованием двух этих устройств, против бактерий E. coli и S. aureus.Представлено результати досліджень антимікробних і поверхневих властивостей тканин з металевими напиленнями, створеними за допомогою магнетрона та чистяче-розпилювального пристрою на базі послідовно розташованих прискорювача з анодним шаром та порожнистого катода. Визначені та співставлені антимікробні властивості тканин з бавовни та суміші бавовна/поліестер з напиленнями з Cu, Ti та Ag, створених за допомогою цих пристроїв, проти бактерій E. coli та S. aureus

International nosocomial infection control consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).
