We summarize the most recent results of observations and investigations concerning the host galaxies and the environment of Quasars and Seyfert galaxies. The results show that most of Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) belong to interacting systems, confirming the expectation that most RLQ are in elliptical galaxies, while contradict the conventional wisdom that RQQ occur in spiral galaxies. Starburst galaxies show strong evidence that they are interacting or merging systems, while for what concerns Seyfert galaxies, the situation is not so clear as for starburst galaxies, mainly because of the criteria used to define the samples.

Abstract
We summarize the most recent results of observations and investigations concerning the host galaxies and the environment of Quasars and Seyfert galaxies. The results show that most of Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) belong to interacting systems, confirming the expectation that most RLQ are in elliptical galaxies, while contradict the conventional wisdom that RQQ occur in spiral galaxies. Starburst galaxies show strong evidence that they are interacting or merging systems, while for what concerns Seyfert galaxies, the situation is not so clear as for starburst galaxies, mainly because of the criteria used to define the samples.Pubblicazioni consigliate
