WASHINGTON (AP) — The same federal scientist who recently found forgotten samples of smallpox at a federal lab also uncovered over 300 additional vials, many bearing the names of highly contagious viruses and bacteria.

Food and Drug Administration officials said Wednesday the undocumented collection contained 327 carefully packaged vials, listing pathogens like dengue, influenza and rickettsia. Last week the government only disclosed that it had recovered six glass vials of smallpox dating from the 1950s.
