BACKGROUND Airborne transmission of pathogenic resistant bacteria is well recognized as an important route for the acquisition of a wide range of nosocomial infections in hospitals. The aim of this study was to determine the prevalence of airborne vancomycin and gentamicin (VM and GM) resistant bacteria in different wards of four educational hospitals. MATERIALS AND METHODS A total of 64 air ...

The technology of airborne remote sensing encompasses a broad class of airborne platforms and a wide suite of remote sensing instruments. Usable platforms range from airships (Hamley, 1994; Windischbauer and Hans, 1994), UAVs (Unmanned Airborne Vehicles, Miller et al., 1999; Petrie, 2001), and helicopters (Gade et al., 1998; Matthews et al., 1997; Schaepman et al., 1997), to standard and high-a...

Background In Japan, information of daily airborne Japanese cedar pollen counts is made public during pollen season. If symptoms severity and treatment outcome are predictable according to these pollen counts, management of seasonal allergic rhinitis may become more precise. Aims of the study To evaluate the relationship between airborne pollen counts, symptoms severity and treatment outcome in...

OBJECTIVE An Asian dust storm (ADS) contains airborne particles that affect conditions such as asthma, but the mechanism of exacerbation is unclear. The objective of this study was to compare immune adjuvant effects and airway inflammation induced by airborne particles collected on ADS days and the original ADS soil (CJ-1 soil) in asthma model mice. METHODS Airborne particles were collected o...

Ground-based pseudolite systems have some limitations, such as low vertical accuracy, multipath effects and near-far problems. These problems are not significant in airborne-based pseudolite systems. However, the monitoring of pseudolite positions is required because of the mobility of the platforms on which the pseudolites are mounted, and this causes performance degradation. To address these ...

Dobeic M., Kenda E., Mičunovič J., Zdovc I. (2011): Airborne Listeria spp. in the red meat processing industry. Czech J. Food Sci., 29: 441–447. The aim of this study was to determine the potential presence of the airborne Listeria spp. and its correlation with the aerobic mesophilic bacteria and Listeria carcass contamination in three red meat slaughtering and three processing plants. Airborne...

This paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. The study area located in Semnan province of Iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...

Size-fractionated aerosol particles were collected in a hospital emergency department to test for airborne influenza virus. Using real-time polymerase chain reaction, we confirmed the presence of airborne influenza virus and found that 53% of detectable influenza virus particles were within the respirable aerosol fraction. Our results provide evidence that influenza virus may spread through the...

BACKGROUND Airborne mouse allergen has not previously been measured in inner-city homes, and its relationship to settled dust mouse allergen levels is unknown. OBJECTIVE To quantify airborne and settled dust Mus m 1 levels in homes of inner-city patients with asthma and to identify risk factors for mouse allergen exposure. METHODS One hundred inner-city school-age children with asthma in Ba...

We identified home characteristics associated with the level of airborne endotoxin in 111 Boston-area homes enrolled in a cohort study of home exposures and childhood asthma, and we developed a predictive model to estimate airborne endotoxin. We measured endotoxin in family-room air and in dust from the baby's bed, family room, bedroom, and kitchen floor. Level of airborne endotoxin was weakly ...
