Sahachiro Hata
was a prominent Japanese bacteriologist who researched the bubonic plague under Kitasato Shibasaburō and assisted in developing the antisyphilitic drug arsphenamine in 1909 in the laboratory of Paul Ehrlich. Hata received three unsuccessful nominations for the Nobel Prize, one from Swiss surgeon Emil Kocher for Chemistry in 1911 and two by Japanese colleagues Hayazo Ito and G Osawa for Physiology or Medicine in 1912 and 1913, respectively. Early life Hata was born in Tsumo Village, Shimane prefecture (now part of Masuda City) as the eighth son of the Yamane family. At the age of 14, he was adopted by the Hata family, whose male members were doctors from generation to generation. Hata completed his medical education in Okayama at the Third Higher School of Medicine (now Okayama University School of Medicine). In 1897, he became an assistant at Okayama Prefectural Hospital where he learned internal medicine from Zenjiro Inoue and biochemistry from Torasaburo Araki. Plague re ...

Trypanosomatida
Trypanosomatida is a group of kinetoplastid unicellular organisms distinguished by having only a single flagellum. The name is derived from the Greek ''trypano'' (borer) and ''soma'' (body) because of the corkscrew-like motion of some trypanosomatid species. All members are exclusively parasitic, found primarily in insects. A few genera have life-cycles involving a secondary host, which may be a vertebrate, invertebrate or plant. These include several species that cause major diseases in humans. Some trypanosomatida are intracellular parasites, with the important exception of ''Trypanosoma brucei''. Medical importance The three major human diseases caused by trypanosomatids are; African trypanosomiasis (African trypanosomiasis, sleeping sickness, caused by ''Trypanosoma brucei'' and transmitted by Tsetse fly, tsetse flies), South American trypanosomiasis (Chagas disease, caused by ''Trypanosoma cruzi, T. cruzi'' and transmitted by Triatominae, triatomine bugs), and leishmanias ...

Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification.

Erich Hoffmann
Erich Hoffmann (25 April 1868 – 8 May 1959) was a German dermatologist who was a native of Witzmitz, Pomerania. He studied medicine at the Berlin Military Academy, and was later a professor at the Universities of Halle and Bonn. Hoffmann is remembered for his research performed with zoologist Fritz Schaudinn (1871-1906) at the Charité Clinic in Berlin. In 1905 Schaudinn and Hoffmann discovered the bacterium that was responsible for syphilis, a spiral-shaped spirochete called ''Treponema pallidum'', which they first called ''Spirochaeta pallida''. The organism was removed from a papule in the vulva of a woman with secondary syphilis. The two doctors documented their findings in a treatise called ''Vorläufiger Bericht über das Vorkommen von Spirochaeten in syphilitischen Krankheitsprodukten und bei Papillome''.Fritz Richard Schaudinn, Erich Hoffmann: Vorläufiger Bericht über das Vorkommen von Spirochaeten in syphilitischen Krankheitsprodukten und bei Papillomen.

Fritz Schaudinn
Fritz Richard Schaudinn (19 September 1871 – 22 June 1906) was a German zoologist. Born in Röseningken (now in Ozyorsky District) in the Province of Prussia, he co-discovered, with Erich Hoffmann in 1905, the causative agent of syphilis, ''Spirochaeta pallida'' (also known as ''Treponema pallidum''). The work was carried out at the Berlin Charité. Among Schaudinn's other contributions to medicine include his work in the field of amoebic dysentery, sleeping sickness and his confirmation of the work of Sir Ronald Ross and Giovanni Battista Grassi (1854–1925) in the field of malaria research. He also demonstrated that human hookworm infection is contracted through the skin of the feet. He made noted contributions to zoology and was one of the developers of protozoology as an experimental science. Schaudinn was a graduate in zoology of the Friedrich Wilhelm University in Berlin. Since 2002 an annual medical prize has been awarded in his name. In 1898 with zoologist F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treponema Pallidum
''Treponema pallidum'', formerly known as ''Spirochaeta pallida'', is a Microaerophile, microaerophilic, Gram-negative bacteria, gram-negative, spirochaete bacterium with subspecies that cause the diseases syphilis, bejel (also known as endemic syphilis), and yaws. It is known to be transmitted only among humans and baboons. ''T. pallidum'' can enter the host through mucosal membranes or open lesions in the skin and is primarily spread through sexual contact. It is a helically coiled microorganism usually 6–15 μm long and 0.1–0.2 μm wide. ''T. pallidum'''s lack of both a Citric acid cycle, tricarboxylic acid cycle and processes for oxidative phosphorylation results in minimal metabolic activity. As a Chemoorganoheterotrophic, chemoorganoheterotroph, ''Treponema pallidum'' is an obligate parasite that acquires its glucose carbon source from its host. Glucose can be used not only as a primary carbon source but also in glycolytic mechanisms to generate ATP needed to power the ...

Spirochaete
A spirochaete () or spirochete is a member of the phylum Spirochaetota (also called Spirochaetes ), which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled (corkscrew-shaped or spiraled, hence the name) cells. Spirochaetes are chemoheterotrophic in nature, with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm. Spirochaetes are distinguished from other bacterial phyla by the location of their flagella, called endoflagella, or periplasmic flagella, which are sometimes called ''axial filaments''. Endoflagella are anchored at each end (pole) of the bacterium within the periplasmic space (between the inner and outer membranes) where they project backwards to extend the length of the cell. These cause a twisting motion which allows the spirochaete to move. When reproducing, a spirochaete will undergo asexual transverse binary fission. Most spirochaetes are free-living and anaero ...

Portrait Of Paul Ehrlich And Sahachiro Hata Wellcome M0013258
A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face is always predominant. In arts, a portrait may be represented as half body and even full body. If the subject in full body better represents personality and mood, this type of presentation may be chosen. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, to most successfully engage the subject with the viewer, but portrait may be represented as a profile (from aside) and 3/4. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in the Middle East ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plague takes three main forms: Pneumonic plague, pneumonic, Septicemic plague, septicemic, and bubonic plague, bubonic. ''Y. pestis'' is a facultative anaerobic organism, facultative anaerobic Parasitism, parasitic bacterium that can infect humans primarily via its host the Oriental rat flea (''Xenopsylla cheopis''), but also through airborne transmission , aerosols and airborne droplets for its pneumonic form.
