Antibacterial soaps sold with messages about protecting you from disease doesn't kill any more bacteria than regular soaps, researchers say in a new study.

Researchers from the University of Michigan reviewed 27 previous studies from the past 26 years. They found that soaps with triclosan -- the commonly used biocide -- were no more effective at preventing illness or at reducing bacteria levels on hands.

They said that there was also evidence that some studies showed that different species of bacteria have also been shown to develop resistance to triclosan, which could make them harder to kill later.
