It was a new experience for him. “Prior to that time,” he said in an interview, “Infection and Immunity had only retracted nine articles over a 40-year period.”

And it soon became clear that Infection and Immunity was hardly the only victim of Dr. Mori’s misconduct. Since then, other scientific journals have retracted two dozen of his papers, according to the watchdog blog Retraction Watch.

The studies were retracted because they used pictures from older papers, rather than from the experiments described in the studies. “I think this reuse is not a scientific misconduct,” Dr. Mori wrote.

He and his colleagues studied the response of human cells to infection by bacteria and viruses.
