Two experiments (EXP), utilizing the skin attachment model (SAM), were conducted to determine the bactericidal activity of six potential carcass disinfectants [EXP 1: 20, 400, and 800 ppm sodium hypochlorite; EXP 2: 5% acetic acid (AA), 8% trisodium phosphate (TSP), and 1% sodium metabisulfite (SS)] during simulated scalder (50 C for 2 min), chiller (0 C for 60 min), or post-process dip (23 C f...

Biofilm formation on equipment surfaces is a potential food safety hazard, providing increased resistance and persistence of pathogens spoilage microorganisms in production environments. The issue preventing the biofilm extremely important, since wide range disinfectants does not always provide proper effect. article discusses antimicrobial effectiveness with various active ingredients (based c...

This study aims to determine the effectiveness of disinfection 0.5% chlorine and 2.5% didecyldimethylammonium chloride against Staphylococcus aureus Klebsiella pneumoniae in operating room. The method used is a quasi-experimental post-only group design with total sample 40 samples room environment. results showed no difference between two types disinfectants, namely reducing number bacteria (p-...

benzalkonium chloride is a quaternary ammounium compounds derivative under different names such as afxhang, hamoon, mahan etc, which have great and expanded use in sanitation and medical affairs. bactericidal activity of these disinfectants was fulfilled according to national standard method no.2842 on staph. aureus, sal. typhimouium and e. coli. this laboratory test showed that, except mahan t...

BACKGROUND Many of the healthcare associated infections (HCAIs) are transmitted by healthcare workers' hands, which actively contributes to transferring pathogens from patient to patient and within the healthcare environment. Hand hygiene is the easiest and cheapest method for preventing HCAIs. The article presents the compliance with hygiene procedures in a group of medical students of the Wro...

The interpretation of blood culture results has become a day-to-day problem in hospitals. The minireview by M. Weinstein provides excellent insights into the problem in a short, precise, clinically applicable form (3). The reason for the increased rate of contamination is explained in part by the difficulty of sterilizing the skin at the insertion site and/or the catheter. It is implied that on...

background: acinetobacter baumannii plays an important role in some types of nosocomial infections as an opportunist microorganism which increases levels of resistance to antibacterial drugs and disinfectants. objectives: the aim of this study was to determine the resistance and sensitivity of a. baumannii to different antibiotics and evaluate the minimal inhibitory concentration (mic) for cipr...
