New bacteria species found in Rome's tombs
Rome | October 01, 2008 12:01:13 AM IST
Italian scientists say they have discovered two new species of bacteria growing on the walls of some of Rome's ancient tombs. Professor Clara Urzi from the University of Messina said the bacteria was found in the Catacombs of Saint Callistus -- part of a massive graveyard that covers 37 acres. The underground tombs were built at the end of the 2nd Century A.D. and were named after Pope Callistus I. More than 30 popes and martyrs are buried in the catacombs. Bacteria can grow on the walls of these underground tombs and often cause damage, said Urz. We found two new species of bacteria on decayed surfaces in the catacombs and we think the bacteria, which belong to the Kribbella group, may have been involved in the destruction. By studying bacteria that ruin monuments, the researchers hope to develop methods of protecting cultural heritage sites such as the catacombs in Rome. The research is detailed in the September issue of the International Journal of Systematic and Evolutionary Microbiology. (UPI)
