> So far, the CDC has collected and tested more than 100 samples of products, soil, and water from the four patients' homes, but none has turned up positive for B. pseudomallei. The agency noted that tracking down a source of B. pseudomallei can sometimes be difficult as the bacteria can take two to three weeks to develop into an infection, broadening the window of possible exposure times and testing patients' memories.
