Researchers also found samples found in Europe show more of a problem with mutation than the samples taken in the U.S.<\/p>\n<p>\u201cIn Europe, we know they at least have 23 different kinds of mutations,\u201d said Wang. \u201cHere, we only found four mutations in the population.\u201d<\/p>\n<p>Wang recommends implementing non-toxic rodent control measures.
