Scientific career
Fields zoologist, protozoologist, microbiologist

Fritz Richard Schaudinn (19 September 1871 – 22 June 1906) was a German zoologist.

Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek ζῷον, zōion, i.e. "animal" and λόγος, logos, i.e. "knowledge, study".

Born in Röseningken, East Prussia, he co-discovered, with Erich Hoffmann in 1905, the causative agent of syphilis, Spirochaeta pallida (also known as Treponema pallidum). [1] The work was carried out at the Berlin Charité.

East Prussia province of Prussia

East Prussia was a province of the Kingdom of Prussia from 1773 to 1829 and again from 1878 ; following World War I it formed part of the Weimar Republic's Free State of Prussia, until 1945. Its capital city was Königsberg. East Prussia was the main part of the region of Prussia along the southeastern Baltic Coast.

Erich Hoffmann was a German dermatologist who was a native of Witzmitz, Pomerania.

Syphilis Sexually transmitted infection

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents. The primary stage classically presents with a single chancre though there may be multiple sores. In secondary syphilis, a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. In latent syphilis, which can last for years, there are few or no symptoms. In tertiary syphilis, there are gummas, neurological problems, or heart symptoms. Syphilis has been known as "the great imitator" as it may cause symptoms similar to many other diseases.

Among Schaudinn's other contributions to medicine include his work in the field of amoebic dysentery and sleeping sickness, 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.

African trypanosomiasis parasitic disease

African trypanosomiasis, also known as sleeping sickness, is an insect-borne parasitic disease of humans and other animals. It is caused by protozoa of the species Trypanosoma brucei. There are two types that infect humans, Trypanosoma brucei gambiense (TbG) and Trypanosoma brucei rhodesiense (TbR). TbG causes over 98% of reported cases. Both are usually transmitted by the bite of an infected tsetse fly and are most common in rural areas.

Ronald Ross Indian-born British medical doctor and Nobel laureate

Sir Ronald Ross was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on the transmission of malaria, becoming the first British Nobel laureate, and the first born outside Europe. His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease. He was a polymath, writing a number of poems, published several novels, and composed songs. He was also an amateur artist and natural mathematician. He worked in the Indian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. After resigning from his service in India, he joined the faculty of Liverpool School of Tropical Medicine, and continued as Professor and Chairman of Tropical Medicine of the institute for 10 years. In 1926 he became Director-in-Chief of the Ross Institute and Hospital for Tropical Diseases, which was established in honour of his works. He remained there until his death.

Giovanni Battista Grassi Italian zoologist

Giovanni Battista Grassi was an Italian physician and zoologist, most well known for his pioneering works on parasitology, especially on malariology. He was Professor of Comparative Zoology at the University of Catania from 1883, and Professor of Comparative Anatomy at Sapienza University of Rome from 1895 until his death. His scientific contributions covered embryological development of honey bees, on helminth parasites, the vine parasite phylloxera, on migrations and metamorphosis in eels, and on termites. He was the first to describe and establish the life cycle of the human malarial parasite, Plasmodium falciparum, and discovered that only female anopheline mosquitoes are capable of transmitting the disease. His works in malaria remain a lasting controversy in the history of Nobel Prizes, because a British army surgeon Ronald Ross, who discovered the transmission of malarial parasite in birds was given the 1902 Nobel Prize in Physiology or Medicine. But Grassi, who demonstrated the complete route of transmission of human Plasmodium, and correctly identified the types of malarial parasite as well as the mosquito vector, Anopheles claviger, was denied.

In 1898 with zoologist Fritz Römer (1866–1909), he participated on a scientific trip to Svalbard. Results of the expedition led to publication of Fauna Arctica, a project on Arctic fauna begun by Schaudinn and Römer and continued by August Brauer (1863–1917) and Walther Arndt (1891–1944).

Svalbard Archipelago in the Arctic Ocean

Svalbard is a Norwegian archipelago in the Arctic Ocean. Situated north of mainland Europe, it is about midway between continental Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and Edgeøya. Administratively, the archipelago is not part of any Norwegian county, but forms an unincorporated area administered by a governor appointed by the Norwegian government. Since 2002, Svalbard's main settlement, Longyearbyen, has had an elected local government, somewhat similar to mainland municipalities. Other settlements include the Russian mining community of Barentsburg, the research station of Ny-Ålesund, and the mining outpost of Sveagruva. Ny-Ålesund is the northernmost settlement in the world with a permanent civilian population. Other settlements are farther north, but are populated only by rotating groups of researchers.

Arctic polar region on the Earths northern hemisphere

The Arctic is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska, Finland, Greenland (Denmark), Iceland, Northern Canada, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost -containing tundra. Arctic seas contain seasonal sea ice in many places.

Schaudinn died during his journey back to Germany from an International Medicine Meeting in Lisbon, when he underwent an urgent surgery aboard due to gastrointestinal amoebian abscesses. Such amoebian infection had probably been voluntarily acquired when he did research on amoebas. Schaudinn was a little under 35 years of age when he died in Hamburg.

Amoeba polyphyletic group including different eucariot taxons

An amoeba, often called amoeboid, is a type of cell or unicellular organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebas do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals.

Abscess localized collection of pus that has built up within the tissue of the body

An abscess is a collection of pus that has built up within the tissue of the body. Signs and symptoms of abscesses include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. The area of redness often extends beyond the swelling. Carbuncles and boils are types of abscess that often involve hair follicles, with carbuncles being larger.

Amoebiasis human protozoa disease

Amoebiasis, also known amoebic dysentery, is an infection caused by any of the amobae of the Entamoeba group. Symptoms are most common during infection by Entamoeba histolytica. Amoebiasis can be present with no, mild, or severe symptoms. Symptoms may include abdominal pain, diarrhea, or bloody diarrhea. Complications can include inflammation and ulceration of the colon with tissue death or perforation, which may result in peritonitis. People affected may develop anemia due to loss of blood.

Sporotrichosis primary systemic mycosis that results in a systemic fungal infection, has material basis in Sporothrix schenckii in animals and humans and results in formation of red papule at the site of inoculation

Sporotrichosis is a disease caused by the infection of the fungus Sporothrix schenckii. This fungal disease usually affects the skin, although other rare forms can affect the lungs, joints, bones, and even the brain. Because roses can spread the disease, it is one of a few diseases referred to as rose-thorn or rose-gardeners' disease. The species was named for Benjamin Schenck, a medical student who in 1896 was the first to isolate it from a human specimen.

Trichodysplasia spinulosa skin disease found in immunocompromised patients, caused by TSPyV

Trichodysplasia spinulosa is a rare cutaneous condition that has been described almost exclusively in immunocompromised patients, usually organ transplant recipients, on regimens of immunosuppressive drugs. As of early 2016, a total of 32 cases had been reported in the medical literature. Despite its rarity, TS is believed to be underdiagnosed, and the growing population of patients on immunosuppressive drug regimens suggests its incidence may rise. TS has been described as an emerging infectious disease.

Pilomatricoma Human disease

Pilomatricoma, is a benign skin tumor derived from the hair matrix. These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5-3.0 cm, but the largest reported case was 24 cm.

Linear atrophoderma of Moulin is an acquired unilateral dermatitis localized along the Blaschko lines. It affects children or adolescents of both genders, involving the trunk and the limbs. It is, presumably, a rare cutaneous form of mosaicism. This disease was first referred to as Atrophoderma of Moulin after Dr.Moulin who first reported it in 1992 then was renamed as linear atrophoderma of Moulin. Only a few dozen cases have been described; for this reason, LAM is considered to be a very rare disorder.
