John Ashburton Thompson
John Ashburton Thompson (1846 – 16 September 1915) was a British-Australian physician and an international authority on plague and leprosy. Thompson, the eldest son of John Thompson, solicitor, was born in England in August 1846. He was educated at St Paul's School, and University College London, and qualified for the diplomas of the Royal College of Surgeons and Physicians. In 1878 he obtained the degree of M.D. with distinction at the Brussels University. From 1872 to 1878 he was surgeon at King's Cross to the Great Northern Railway Company, and also had a private practice. His health breaking down towards the end of 1878 from overwork, he went first to New Zealand and then to New South Wales. He led an open-air life until his health was completely restored, and in 1883 was sent to Mackay to investigate an epidemic of dengue. Returning to Sydney in 1884 he was given the post of temporary medical officer to the Board of Health, and a year later was appointed its chie ...

British People
British people or Britons, also known colloquially as Brits, are the citizens of the United Kingdom of Great Britain and Northern Ireland, the British Overseas Territories, and the Crown dependencies.: British nationality law governs modern British citizenship and nationality, which can be acquired, for instance, by descent from British nationals. When used in a historical context, "British" or "Britons" can refer to the Ancient Britons, the indigenous inhabitants of Great Britain and Brittany, whose surviving members are the modern Welsh people, Cornish people, and Bretons. It also refers to citizens of the former British Empire, who settled in the country prior to 1973, and hold neither UK citizenship nor nationality. Though early assertions of being British date from the Late Middle Ages, the Union of the Crowns in 1603 and the creation of the Kingdom of Great Britain in 1707 triggered a sense of British national identity.. The notion of Britishness and a shared Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Islands
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul-Louis Simond
Paul-Louis Simond (30 July 1858 – 3 March 1947) was a French physician, chief medical officer and biologist whose major contribution to science was his demonstration that the intermediates in the transmission of bubonic plague from rats to humans are the fleas '' Xenopsylla cheopis'' that dwell on infected rats. Early life Paul-Louis Simond was born in Beaufort-sur-Gervanne, ( Drome, France) on 30 July 1858. His father was a pastor of the Reformed Church. From 1878 to 1882 Simond was an assistant in Medical and Biological Sciences at the School of Medicine and Pharmacy in Bordeaux, and he began his medical training there. From 1882 to 1886 he served as director of the leprosarium in Acarouany near Saint-Laurent-du-Maroni, French Guiana, where he contracted an attenuated form of yellow fever. He returned to Bordeaux in 1886 and the following year he received his medical doctorate with a prize-winning thesis on leprosy. Career In 1895 he began work at the Pasteur Institute in ...

Insects
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Diseases
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths). The branch of medicine that focuses on infections is referred to as infectious disease. Types Infections are caused by infectious agents (pathogens) including: * Bacteria (e.g. ''Mycobacterium tuberculosis'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Medicine
The field of social medicine seeks to implement social care through # understanding how social and economic conditions impact health, disease and the practice of medicine and # fostering conditions in which this understanding can lead to a healthier society. Social medicine as a scientific field gradually began in the early 19th century, the Industrial Revolution and the subsequent increase in poverty and disease among workers raised concerns about the effect of social processes on the health of the poor. The field of social medicine is most commonly addressed today by public health efforts to understand what are known as social determinants of health. Scope The major emphasis on biomedical science in medical education, health care, and medical research has resulted into a gap with our understanding and acknowledgement of far more important social determinants of public health and individual disease: social-economic inequalities, war, illiteracy, detrimental life-styles (smoki ...

Fleas
Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by ingesting the blood of their hosts. Adult fleas grow to about long, are usually brown, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers. They lack wings; their hind legs are extremely well adapted for jumping. Their claws keep them from being dislodged, and their mouthparts are adapted for piercing skin and sucking blood. They can leap 50 times their body length, a feat second only to jumps made by another group of insects, the superfamily of froghoppers. Flea larvae are worm-like, with no limbs; they have chewing mouthparts and feed on organic debris left on their hosts' skin. Genetic evidence indicates that fleas are a specialised lineage of parasitic scorpionflies (Mecoptera) ''sensu lato'', most closely related to the family Nannochorist ...

Yersinia Pestis
''Yersinia pestis'' (''Y. pestis''; formerly '' Pasteurella pestis'') is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both ''Yersinia pseudotuberculosis'' and ''Yersinia enterocolitica''. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea (''Xenopsylla cheopis''). It causes the disease plague, which caused the first plague pandemic and the Black Death, the deadliest pandemic in recorded history. Plague takes three main forms: pneumonic, septicemic, and bubonic. ''Yersinia pestis'' is a parasite of its host, the rat flea, which is also a parasite of rats, hence ''Y. pestis'' is a hyperparasite. ''Y. pestis'' was discovered in 1894 by Alexandre Yersin, a Swiss/French physician and bacteriologist from the Pasteur Institute, during an epidemic of the plague in Hong Kong. Yersin was a member of the Pasteur school of thought. Kitasato Shibasaburō, a Japanese bacteriologist who practised Koch's me ...

Plague (disease)
Plague is an infectious disease caused by the bacterium ''Yersinia pestis''. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die. The bubonic and septicemic forms are generally spread by flea bites or handling an infected animal, whereas pneumonic plague is generally spread between people through the air via infectious droplets. Diagnosis is typically by finding the bacterium in fluid from a lymph node, blood or sputum. Those at high risk may be vaccinated. Those exposed to a case of pneumonic plague may be treated with preventive medication. If infected, treatment is with antibiotic ...
