Uncovering The History Of Medieval Leprosy With Genomics
2013-06-14 14:24:28

Lee Rannals for redOrbit.com — Your Universe Online Scientists are using thousand-year-old remains to help reconstruct the genomes of the medieval leprosy pathogen and uncover the history of the disease. Researchers wrote in Science magazine about how they used the remains of skeletons to successfully reconstruct a dozen medieval and modern genomes of the leprosy-causing bacteria Mycobacterium leprae. They were able to create a genome from archaeological finds for the first time...

Leprosy cases reported in the US only number around 150 per year and the majority of these cases can be attributed to travel to places such as Angola, Brazil and India. However, Scientists have identified a source for some of the unexplained cases that appear in the southern US - the nine-banded armadillo. DNA samples were taken from 33 wild armadillos in Arkansas, Alabama, Louisiana, Mississippi and Texas. Armadillos are one of the very few mammals that can carry the bacteria causing the...

(Ivanhoe Newswire) -- A new study published in the New England Journal of Medicine reveals a new strain of leprosy has surfaced in the Southern United States. Leprosy is a chronic, mildly contagious disease of tropical and subtropical regions with a long and extensive history. Until the 20th century, infected people were ostracized from society or at best segregated and cared for in isolated leper colonies. Today, the disease is entirely curable through multidrug therapy, though tissue damage...

Largest genome-wide association study of an infectious disease In the first genome-wide association study (GWAS) of leprosy and the largest GWAS on an infectious disease, scientists at the Genome Institute of Singapore (GIS) and 26 institutes in China identified seven genes that increase an individual's susceptibility to leprosy. The discovery of these genes, reported in the 16 Dec. 2009 New England Journal of Medicine, highlights the important role of the innate immune response in the...

For thousands of years an undesirable and persistent companion has been traveling with man wherever he goes. Mycobacterium leprae, the bacterium that causes leprosy, has only one known natural host "“ mankind. And because of man's many travels, this bacillus has colonized the entire earth. Its history is therefore intimately tied to our own, and it is this migratory relationship that Stewart Cole, EPFL professor of Microbial Pathogenesis, and his team have analyzed in a study to be...

Researchers claim to have discovered the earliest evidence of leprosy in a 4,000-year-old skeleton from India. Gwen Robbins, an anthropologist at Appalachian State University, and a team of archaeologists from Deccan College in Pune, India, found the skeleton at the site of Balathal in Rajasthan. The region was thriving from about 3700 to 1800 B.C., they reported in the peer-reviewed journal PLoS One. Robbins' team reported that the skeleton shows evidence of erosion caused by leprosy. It...

A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology.All cases of leprosy, an ancient disease that still maims and kills in the developing world, previously had been thought to be caused by a single species of bacterium, said lead author Xiang-Yang Han, M.D., Ph.D., associate professor in Laboratory Medicine at The...

Mycobacterium leprae, mostly found in warm tropical countries, is a bacterium that causes leprosy (Hansen's disease). It is an intracellular, pleomorphic, acid-fast bacterium. M. leprae is an aerobic rod-shaped surrounded by the characteristic waxy coating unique to mycobacteria tuberculosis. Due to its thick waxy coating, M. leprae stains with a carbol fuscin rather than with the traditional Gram stain. Gerhard Armauer Hansen first discovered it in 1873. It was the first bacterium to be...
