How are climate change and environmental pollution affecting the spread of pathogens in water? This isn’t fully understood yet, which is why a team from the Istituto Superiore di Sanità (ISS) in Italy is researching the potential spread of pathogens (PSP).Their test site is Lake Paola, also known as Lake Sabaudia. It’s a coastal brackish lake in Lazio, with an area of about 3.9km2. The study will focus particularly on the antibiotic-resistant profiles of pathogens, which is of great concern to public health.
