buy gabapentin cheap The sample came from a Hungarian woman, Terézia Hausmann, who died aged 28 on 25 December 1797. Her mummified remains were recovered from a crypt in the town of Vác, Hungary.

The beauty of metagenomics is that it provides a simple but highly informative approach that works in a wide variety of contexts.
Professor Pallen added, “It was fascinating to see the similarities between the TB genome sequences we recovered and the genome of a recent outbreak strain in Germany. In this case, metagenomes revealed that some strain lineages have been circulating in Europe for more than two centuries.”
