Biohazard sensors showed the presence of small amounts of potentially dangerous tularemia bacteria in the Mall area last weekend as huge crowds assembled there, but health officials said they believed the levels were too low to be a threat.
Health authorities in the Washington area were notified yesterday that the bacteria were found in and near the area between the U.S. Capitol and the Lincoln Memorial, where crowds gathered Saturday for an antiwar rally and a book festival.

The germ that causes tularemia is considered a biohazard because it is highly infectious and
