Search for diffuse fluxes of cosmic neutrinos with the ANTARES telescope

The ANTARES neutrino telecope is the largest operating underwater telescope. Searches for high-energy cosmic sources of neutrinos have been conducted looking at data collected from 2007 to 2013. Good sensitivity is reached in searching for diffuse fluxes of cosmic neutrinos, both in all sky and in defined regions. The most recent results of these searches are reported in this contribution
