WASHINGTON: Direct test for detecting disease-causing E. coli bacteria developed - (Thaindian News)
February 19, 2008 – 7:27 pmJapanese biochemists have developed a novel direct test needed for detecting the presence of E. coli bacteria that enters water and food due to faecal contamination.
Every year, millions of cases of food poisoning and other gastrointestinal illness around the world have been reported due to such contamination.
The discovery has been credited to Yasunori Tanji and colleagues, who indicated in their report that existing tests do not directly identify E. coli. On the other hand, they detect coliform bacteria, used by health use as indicators for faecal contamination.
However, Coliforms can originate from natural sources, and are not always reliable indicators of faecal contamination. So, there exists direct tests for E. coli, but they take a lot of time and are too complex for general use.
