By what common name is Hansen's Disease better known
Gerhard Armauer Hansen epidemiological studies that leprosy was a specific disease with a specific cause. In 1870–71 Hansen travelled to Bonn and Vienna to gain the training necessary for him to prove his hypothesis. In 1873, he announced the discovery of "Mycobacterium leprae" in the tissues of all sufferers, although he did not identify them as bacteria, and received little support. The discovery was made with a "new and better" microscope. In 1879 Hansen gave tissue samples to Albert Neisser, who then successfully stained the bacteria and announced his findings in 1880, claiming to have discovered the disease-causing organism. There was some dispute
Common disease-common variant to common diseases. Research has linked common SNPs to diseases such as type 2 diabetes, Alzheimer's, schizophrenia and hypertension. Common disease-common variant The common disease-common variant (often abbreviated CD-CV) hypothesis predicts that common disease-causing alleles, or variants, will be found in all human populations which manifest a given disease. Common variants (not necessarily disease-causing) are known to exist in coding and regulatory sequences of genes. According to the CD-CV hypothesis, some of those variants lead to susceptibility to complex polygenic diseases. Each variant at each gene influencing a complex disease will have a small additive or multiplicative effect on the
