Louis Manceaux
Louis Herbert Manceaux (1865–1934) was a French physician, parasitologist, and co-discover of ''Toxoplasma gondii'' with Charles Nicolle in 1908. Biography Manceaux's life is not well known, but he was physician-scientist recruited by Charles Nicolle to study at the Pasteur Institute of Tunis. He assisted Nicolle with capturing gundi in the Djerid Desert to study a parasite associated with a disease known as oriental sore in North Africa. The parasite observed in the tissue samples rodents was originally named Leishmania gondii in 1908. Upon further analysis, they concluded that the parasite was a newly discovered genus, so it was renamed to Toxoplasma gondii in 1909. After his discovery, Manceaux served as a French military doctor and was on active duty with medical corps during World War I. After retiring from the Army An army (from Old French ''armee'', itself derived from the Latin verb ''armāre'', meaning "to arm", and related to the Latin noun ''arma'', meaning ...

French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in Brittany, Occi ...

Parasitologist
Parasitology is the study of parasites, their hosts, and the relationship between them. As a biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of life. This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology, immunology, genetics, evolution and ecology. Fields The study of these diverse organisms means that the subject is often broken up into simpler, more focused units, which use common techniques, even if they are not studying the same organisms or diseases. Much research in parasitology falls somewhere between two or more of these definitions. In general, the study of prokaryotes falls under the field of bacteriology rather than parasitology. Medical The parasitologist F.E.G. Cox noted that "Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa, some derive ...

Toxoplasma Gondii
''Toxoplasma gondii'' () is an obligate intracellular parasitic protozoan (specifically an apicomplexan) that causes toxoplasmosis. Found worldwide, ''T. gondii'' is capable of infecting virtually all warm-blooded animals, but felids, such as domestic cats, are the only known definitive hosts in which the parasite may undergo sexual reproduction. ''T. gondii'' has been shown to alter the behavior of infected rodents in ways that increase the rodents' chances of being preyed upon by felids. Support for this "manipulation hypothesis" stems from studies showing that ''T. gondii''-infected rats have a decreased aversion to cat urine. Because cats are the only hosts within which ''T. gondii'' can sexually reproduce to complete and begin its lifecycle, such behavioral manipulations are thought to be evolutionary adaptations that increase the parasite's reproductive success. Rats that do not avoid cat habitations will more likely become cat prey. ''Toxoplasma gondii'' infection i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Nicolle
Charles Jules Henri Nicolle (21 September 1866 – 28 February 1936) was a French bacteriologist who received the Nobel Prize in Medicine for his identification of lice as the transmitter of epidemic typhus. Family Nicolle was born to Aline Louvrier and Eugène Nicolle in Rouen, France and was raised as part of a middle class family that valued education. He had two other siblings – his older brother, Maurice Nicolle (a medical microbiologist, professor at the Pasteur Institute in Paris, and Director of the Bacteriological Institute of Constantinople), and his younger brother, Marcel Nicolle (an art critic). Nicole later married Alice Avice in 1895, and had two children, Marcelle (b. 1896) and Pierre (b. 1898), both of whom also went on to enter the medical field. Studies and career The earliest educational influences on Nicolle were from his father, a doctor at a Rouen hospital. Nicolle later received his education from the '' Lycée Pierre Corneille'' in Rouen, followe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasteur Institute Of Tunis
The Pasteur Institute of Tunis (Arabic: معهد باستور بتونس), located in Tunis, Tunisia is one of the main research centers of the International Network of Institutes Pasteur. History Foundation Founded in 1893 by Adrien Loir, it was initially made to be a rabies vaccine center. Located in rue des Tanneurs in Tunis, and now the laboratory currently does research on winemaking and diseases of the vine. A large part of the institutions prestige can be contributed to Charles Nicolle, a bacteriologist and the director between 1902-1936, who discovered the cause of typhus ( ''Rickettsia spp''.) during this period of time. Nobel Prize for Charles Nicolle Nicolle is rewarded for his discoveries by the Nobel Prize in Physiology or Medicine in 1928 and the Pasteur Institute is honored on this occasion.

Gundi
Gundis or comb rats (family Ctenodactylidae) are a group of small, stocky rodents found in Africa. They live in rocky deserts across the northern parts of the continent. The family comprises four living genera and five species ( Speke's gundi, Felou gundi, Val's or desert gundi, common or North African gundi and Mzab gundi), as well as numerous extinct genera and species. They are in the superfamily Ctenodactyloidea. Local people in northern Africa have always known about gundis, however they first came to the notice of western naturalists in Tripoli in 1774, and were given the name ''gundi mice''. While they are not regarded as pests, some people hunt gundis for food. Description Gundis are from 17 to 18 cm in body length, with compact bodies covered in soft fur, short legs, and large eyes. They have only four toes on all feet and the middle toes of the hind feet carry comb-like bristles, which earned them the name "comb rat". Gundis have short tails, which in some ...

Cutaneous Leishmaniasis
Cutaneous leishmaniasis is the most common form of leishmaniasis affecting humans. It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sand fly. There are about thirty species of ''Leishmania'' that may cause cutaneous leishmaniasis. This disease is considered to be a zoonosis (an infectious disease that is naturally transmissible from animals to humans), with the exception of ''Leishmania tropica'' — which is often an anthroponotic disease (an infectious disease that is naturally transmissible from humans to vertebrate animals). Signs and symptoms Post kala-azar dermal leishmaniasis Post-kala-azar dermal leishmaniasis (PKDL) is a recurrence of kala-azar that may appear on the skin of affected individuals months and up to 20 years after being partially treated, untreated or even in those considered adequately treated. In Sudan, they can be demonstrated in up to 60% of treated cases. They manifest as hypopigmented ski ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Army
The French Army, officially known as the Land Army (french: Armée de Terre, ), is the land-based and largest component of the French Armed Forces.

Pasteur Institute
The Pasteur Institute (french: Institut Pasteur) is a French non-profit private foundation dedicated to the study of biology, micro-organisms, diseases, and vaccines. It is named after Louis Pasteur, who invented pasteurization and vaccines for anthrax and rabies. The institute was founded on 4 June 1887, and inaugurated on 14 November 1888. For over a century, the Institut Pasteur has researched infectious diseases. This worldwide biomedical research organization based in Paris was the first to isolate HIV, the virus that causes AIDS, in 1983. Over the years, it has been responsible for discoveries that have enabled medical science to control diseases such as diphtheria, tetanus, tuberculosis, poliomyelitis, influenza, yellow fever, and plague. Since 1908, ten Institut Pasteur scientists have been awarded the Nobel Prize for medicine and physiology—the 2008 Nobel Prize in Physiology or Medicine was shared between two Pasteur scientists.
