conclusions the study showed that elevator buttons could lead to transmission of pathogenic bacteria. it is necessary to clean and disinfect elevator buttons daily, especially in departments with high contamination potential such as laboratories, particularly in biological laboratories and pilot plant rooms. methods the study was a across sectional research. samples were taken from elevator but...
This study was conducted to investigate the bacterial contamination of air and the surface of equipment and facilities in hatchery. In addition, the inhibitory effects of formaldehyde application methods on aerosol bacterial counts in the hatchers were also investigated. In the operating hatchers, the contamination of air by aerobic bacteria, coliform, and fungi was high, measuring over 300 cfu...
PURPOSE Prevention of multidrug resistant (MDR) bacterial contamination remains a major challenge in ICUs. Many hospital outbreaks involving MDR transmitted through environmental contamination have been reported. Bedside high-density EEG allow for dynamic cognitive evaluation in brain-injured patients and is used more and more frequently in clinical practice to evaluate brain function and predi...
background: various reasons accounted for the infection of infants kept at neonatal intensive care unit (nicu). expressed breast milk may be regarded as a source of infection in infants. this study investigated the source of bacterial contamination and the impact of educational interventions on the contamination of mothers’ expressed breast milk (ebm) level whose infants are hospitalized at nic...
