In medieval treatises speculated about the parasitic nature of scabies.Credible
evidence of the role of scabies mites in the development of the disease
appear only after the creation of an optical microscope. In
1687, the Italian physician Giovanni Cosimo Bonomo and pharmacist
Dyachinto Cheston first described the link between scabies and typical
skin symptoms that develop after infection. It was the first time they have found that the disease can be caused by microscopic organisms.Full and accurate description of the etiology and pathogenesis gave in 1844 a German dermatologist Ferdinand Hebra. This manual was in 1876 translated into Russian Polotebnevym AG.
Angina (from the Latin. Ango - squeeze, soul), an acute infectious disease with a primary lesion of the tonsils. The causative agent - usually strep.
