LAUSANNE, Switzerland —  No drug cheats were found at the recent swimming world championships.

Swimming's international governing body said Wednesday it had completed 391 doping tests conducted in Rome, and all were negative.

FINA said 162 samples were screened for the blood-boosting hormone EPO during the July 15-Aug. 2 championships.

Almost two-thirds of the tests (252) were taken from swimmers, with 65 from water polo players, 33 from divers, 30 from athletes in open water races and 11 from synchronized swimmers.

FINA does not store samples for future analysis using newly developed doping tests, but said it was considering the policy.

The championships were notable for 43 world records set in the swimming events, largely because of high-tech, water-resistant body suits. The suits will be banned at the end of the year.

Michael Phelps of the United States was selected the best male swimmer for winning five gold medals and one silver, while setting individual world records in the 100- and 200-meter butterfly.

Federica Pellegrini of Italy, who won two golds and set three world marks in the 200 and 400 freestyle events, was best female swimmer.
