Nursing staffing and skill mix in nursing homes in Italy: An observational cross-sectional study.

Introduction/objective: The relationship between staffing levels and skill mix in nursing homes is poorly documented in Italy. This study aimed to investigate nursing staffing levels and skill mix in Northern Italian nursing homes.

Methods: A cross-sectional observational study was conducted using a questionnaire sent to several nursing homes.

The highly toxic oxyanion tellurite (TeO (3) (2-) ) enters the phototrophic bacterium Rhodobacter capsulatus via an as yet uncharacterized monocarboxylate transport system.

The facultative phototroph Rhodobacter capsulatus takes up the highly toxic oxyanion tellurite when grown under both photosynthetic and respiratory growth conditions. Previous works on Escherichia coli and R. capsulatus suggested that tellurite uptake occurred through a phosphate transporter.
