Copper (Cu) is a reddish-brown chemical element, a ductile and malleable metal. It is normally found in the environment both in a wide variety of mineral salts and organic compounds and in metallic form. Over the years, the use of metals has increased significantly and the likelihood of their accumulation and impact at various trophic levels is exp...

Reptile-associated salmonellosis (RAS), Salmonella infection in humans, is acquired through contact with reptiles. Reptiles have become popular pet animals, and RAS is likely to be an underestimated but growing problem. No epidemiological data about RAS are routinely collected in Italy. In order to estimate the occurrence of RAS in the Italian huma...

Fish mycobacteriosis is a widespread global problem caused by species of non-tuberculous mycobacteria (NTM). Mycobacterium marinum is one of the species most often involved in disease episodes of aquarium and farmed fish. Since there is currently no available effective therapy or vaccine, a prompt search for routes of entry is key to limiting the d...
