Abstract

Legionella and Pseudomonas aeruginosa are pathogens that live and multiply in water systems and resist disinfection through biofilm formation. As suggested by some studies, we wanted to verify whether the presence of P. aeruginosa can lead to a less frequent presence of Legionella in water systems of retirement homes and group homes. We collected 123 hot water and biofilm samples from showerheads.

ABSTRACT

Background

Hospitals have undergone important that changes that have led, in recent decades at the international level, to the need for greater integration between hospitals and local healthcare services. The main institutional networks that have been developed in Italy are, as commended by the institutional levels, of 4 main types: the Emergency-Urgency Network, the Time-Dependent Networks, the Oncological Networks, and the Networks with primary care settings. It was important to assess the state of the art and analyze it in relation to possible future developments.

Abstract

At the international level, it is necessary to apply urban health strategies that can integrate concrete actions to protect and promote health in urban and architectural planning. In cities, the “urban fauna” mostly consists of synanthropic birds (sparrows, starlings, swallows, martins, jackdaws, crows, hawks, gulls, pigeons) that have adapted to a continuous relationship with humans.
