conclusion silver nanoparticles had appropriate effects in all three types of dilutions and allowing for a more protracted contact time has given significantly better results. patients and methods we have selected nine patients' metal file covers and following sterilizing, we have infected them with one of these bacteria; staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus. t...
INTRODUCTION AND OBJECTIVE The presence of airborne bacteria in hospital environments is of great concern because of their potential role as a source of hospital-acquired infections (HAI). The aim of this study was the determination and comparison of the concentration of airborne bacteria in different wards of four educational hospitals, and evaluation of whether particle counting could be pred...
Survey of hospital environment regarding the presence of Staphylococcus aureus producing β-lactamase
Staphylococcus aureus is a common cause of hospital-acquired infections. This bacterium is resistant to β-lactam antibiotics. The aim of this study was to evaluate the prevalence of S. aureus strains producing enzymes capable of destroying β-lactam antibiotics in a hospital environment. This descriptive and analytic study was performed in Besat Hospital, Sanandaj, Iran, 2016, on 158 swabs colle...
Free-living amoebae can harbour bacteria inside their cysts giving them a microhabitat and protecting them from disinfectants. The aim of this study was to evaluate the potential importance of "Limax amoebae" as vectors for environmental and nosocomial bacteria in a hospital. It was shown that free-living amoebae are ubiquitous in the investigated hospital, occur syntopically with facultative h...
Large quantities of disinfectants are used in hospitals, externally on human skin or to eliminate microorganisms from inanimate objects. After use, residual quantities of these products reach the wastewater, exposing the bacteria that survive in hospital wastewaters to a wide range of biocides that could act as a selective pressure for the development of resistance. Increasing attention has bee...
INTRODUCTION Insects have been described as mechanical vectors of nosocomial infections. METHODS Non-biting flying insects were collected inside a pediatric ward and neonatal-intensive care unit (ICU) of a Brazilian tertiary hospital. RESULTS Most (86.4%) of them were found to carry one or more species of bacteria on their external surfaces. The bacteria isolated were Gram-positive bacilli ...
