New evidence suggests that “super­colonizers” form seeable clusters(丛)on the plastic in minutes.Other findings indicate that some types of harmful bacteria favor plastics more than others.And，scientists are exploring if fish or other ocean animals may be helping these pathogens(病原体)develop quickly by taking in the plastic.That could allow bacteria to acquire additional nutrients as they pass through the guts(肠子)of the fish，said Tracy Mincer，an associate scientist at Woods Hole Oceanographic Instiution in Woods hole，Mass.

　　Showing this information could help scientists better understand how much of a potential threat these harmful bacteria cause and the role the Plastisphere plays in the largest ocean ecosystem，including its potential to change nutrients in the water.That information could also help reduce the impact of plastic pollution in the ocean，Mincer said.
