SINGAPORE/U.S.A — New research has found that flies hold more harmful bacteria than scientists previously believed. <br /> <br />Details of the findings were published in the journal Scientific Reports. The research team involved an international team of scientists from Singapore and the U.S.A. <br /> <br />Scientists found over 600 bacteria inside an analysis of 116 flies. House flies were laden 351 different kinds of bacteria while the blowfly was found to contain 316 types. <br /> <br />Scientists believe that flies bred with no germs could be used as a means to observe and measure public health. These would be released into the environment, before being captured at a later date for analysis.
