Bath trounced Mogliano to extend their lead at the top of Pool Two.
The hosts had the bonus point wrapped up inside 30 minutes, with a Matt Garvey brace and further scores by Matt Banahan, George Ford and a penalty try handing them a 29-0 lead at the break.
Bath continued to dominate after the interval, running in a further six tries to complete an emphatic win.
Banahan took his tally to four, while Carl Fearns and two tries by Olly Woodburn completed the scoring.
Mogliano's failure to register a single point means they have scored fewer than any other team in this season's Challenge Cup and leaves them bottom of their pool.
Bath head coach Mike Ford:
"I'm pleased after what's happened over the last two weeks.
"It was a solid performance over there and I thought we played a little bit better at home.
"It was a good opportunity for us to keep playing - no matter what the score was."
