Could we predict airborne Aspergillus contamination during construction work?

Background: Aspergillus fumigatus is a major opportunistic pathogen causing nosocomial infection. Hospital outbreaks of invasive aspergillosis have been associated with demolition and building construction. This study was designed to examine the impact of meteorologic factors and different periods of work on outdoor fungal airborne concentrations.

Environmental contamination with extended-spectrum β-lactamases: is there any difference between Escherichia coli and Klebsiella spp?

Background: The hospital environment contributes to the spread of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-PE) during outbreaks. We aimed to assess the rate of environmental contamination in rooms occupied by ESBL carriers or infected children and to identify risk factors associated with contamination.

Methods: Five environmental surface samples were systematically performed in rooms occupied by ESBL-PE carrier or infected children.
