Evaluation of a shoe sole UVC device to reduce pathogen colonization on floors, surfaces and patients

Conclusion A UVC decontamination device was shown to reduce the colony-forming unit counts of relevant pathogenic organisms from shoe soles with subsequent decreased colonization of floors, healthcare equipment, furniture, beds and a patient dummy.

Few studies explore how diarrhoeal mortality varies subnationally, especially by cause, which is important for targeting investments. Even fewer examine indirect effects of diarrhoeal morbidity on child mortality. We estimated the subnational d...

Authors: Christensen LFB, Schafer N, Wolf-Perez A, Madsen DJ, Otzen DE Abstract Functional amyloid (FuBA) is produced by a large fraction of all bacterial species and represents a constructive use of the stable amyloid fold, in contrast to the pathological amyloid seen in neurodegenerative diseases. When assembled into amyloid, FuBA is unusually robust and withstands most chemicals including denaturants and SDS. Uses include strengthening of bacterial biofilms, cell-to-cell communication, cell wall construction and even bacterial warfare. Biogenesis is under tight spatio-temporal control, thanks to a simple but eff...

Conclusion: Some Lactobacillus strains exhibit anti-CRE activity, which suggests potential applications for controlling or preventing CRE colonization or infection. Introduction Although Enterobacteriaceae are normal flora of the human intestinal system, they are also common pathogens causing human infections in the setting of both community-acquired and healthcare-associated infections (Hsueh et al., 2010; Toh et al., 2012; Lai et al., 2014; Jean et al., 2016). In this era of widespread antibiotic resistance, Enterobacteriaceae are no exception. Recently, the emergence of carbapenem-resistant Enterobacteriaceae (C...

In conclusion, we demonstrated that the selective boosting of lung innate immunity is a conceptually advantageous approach for improving the effectiveness of antibiotic treatment and fighting antibiotic-resistant bacteria. Introduction Pneumonia constitutes a major cause of death, morbidity and health resource use worldwide. The main causative agents identified in adult patients hospitalized for community-acquired pneumonia (CAP) are viruses (in 27–30% of cases, the most common being rhinovirus, influenza and coronavirus) and bacteria (14–23% of cases, with a marked predominance of Streptococcus pneumonia...

as R, Wood TK, Tomás M Abstract SUMMARYPathogens that infect the gastrointestinal and respiratory tracts are subjected to intense pressure due to the environmental conditions of the surroundings. This pressure has led to the development of mechanisms of bacterial tolerance or persistence which enable microorganisms to survive in these locations. In this review, we analyze the general stress response (RpoS mediated), reactive oxygen species (ROS) tolerance, energy metabolism, drug efflux pumps, SOS response, quorum sensing (QS) bacterial communication, (p)ppGpp signaling, and toxin-antitoxin (TA) systems of ...

CONCLUSION Surfaceskins doorplates were efficient at reducing surface contamination by S. aureus, E. faecalis and E. coli. Reducing microbial contamination of frequently touched door surfaces, and so bacterial transfer via hands, could feasibly reduce the risk of healthcare associated and other infections.
