Campylobacter Coli
''Campylobacter coli'' is a Gram-negative, microaerophilic, non-endospore-forming, S-shaped bacterial species within genus '' Campylobacter''. In humans, it ''C. coli'' can cause campylobacteriosis, a diarrhoeal disease which is the most frequently reported foodborne illness in the European Union. ''C. coli'' grows slowly with an optimum temperature of 42 °C. When exposed to air for long periods, they become spherical or coccoid shaped. History In the year 1886, Theodor Escherich established that spiral form bacteria were noted in the stool specimen and large intestinal mucous of neonates (an infant less than 4 weeks), and kittens. However, it was not until 1957, as widely spread as the bacteria were, '' Campylobacter'' was still not implicated in the human diarrhea. Further to this, in 1973, ''Campylobacter'' was proposed as a novel genus. Pathogenicity and transmission ''Campylobacter coli'' are thought to be mainly transmitted to humans via handling and eating ra ...

Doyle L
Doyle is a surname of Irish origin. The name is a back-formation from O'Doyle, which is an Anglicisation of the Irish (), meaning "descendant of ''Dubhghall''". There is another possible etymology: the Anglo-Norman surname ''D'Oyley'' with agglutination of the French article ''de'' (cf. Disney). It means 'from Ouilly', name of a knight who originated from one of the places named Ouilly in Normandy, such as Ouilly-le-Tesson (Calvados, ''Oylley'' 1050), Ouilly-le-Vicomte (Calvados, ''de Oilleio'' 1279), etc. The relationship with the family D'Oyly is unknown. The personal name ''Dubhghall'' contains the elements ''dubh'' "black" + ''gall'' "stranger". Similar Scottish and Irish surnames, derived from the same personal name are: ''MacDougall'' / '' McDougall'' and '' MacDowell'' / '' McDowell''. During the Viking Age the term '' Dubhghoill'' was used to describe the Vikings—usually Danes—and the term ''Fionnghoill'' ("fair foreigners") was used to describe Norwegians. There ...

Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microaerophilic
A microaerophile is a microorganism that requires environments containing lower levels of dioxygen than that are present in the atmosphere (i.e. < 21% O2; typically 2–10% O2) for optimal growth. A more restrictive interpretation requires the microorganism to be obligate in this requirement. Many microaerophiles are also capnophiles, requiring an elevated concentration of (e.g. 10% CO2 in the case of '' Campylobacter'' ). The original definitio ...

Endospore
An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. The name "endospore" is suggestive of a spore or seed-like form (''endo'' means 'within'), but it is not a true spore (i.e., not an offspring). It is a stripped-down, dormant form to which the bacterium can reduce itself. Endospore formation is usually triggered by a lack of nutrients, and usually occurs in gram-positive bacteria. In endospore formation, the bacterium divides within its cell wall, and one side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries. There are many reports of spores remaining viable over 10,000 years, and revival of spores millions of years old has been claimed. There is one report of viable spores of ''Bacillus marismortui'' in salt crystals approximately 250 million years old. When the environment becomes more favorable, the endospore can reactivate itself into a vegetative state. Mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiral Bacteria
Spiral bacteria, bacteria of spiral (helical) shape, form the third major morphological category of prokaryotes along with the rod-shaped bacilli and round cocci. Spiral bacteria can be subclassified by the number of twists per cell, cell thickness, cell flexibility, and motility. The two types of spiral cells are spirillum and spirochete, with spirillum being rigid with external flagella, and spirochetes being with internal flagella. Spirillum A spirillum (plural spirilla) is a rigid spiral bacterium that is Gram-negative and frequently has external amphitrichous or lophotrichous flagella. Examples include: * Members of the genus ''Spirillum'' * '' Campylobacter'' species, such as ''Campylobacter jejuni'', a foodborne pathogen that causes campylobacteriosis * ''Helicobacter'' species, such as ''Helicobacter pylori'', a cause of peptic ulcers Spirochetes A spirochete (plural spirochetes) is a very thin, elongate, flexible, spiral bacteria that is motile via internal peripla ...

Campylobacter
''Campylobacter'' (meaning "curved bacteria") is a genus of Gram-negative bacteria. ''Campylobacter'' typically appear comma- or s-shaped, and are motile. Some ''Campylobacter'' species can infect humans, sometimes causing campylobacteriosis, a diarrhoeal disease in humans. Campylobacteriosis is usually self-limiting and antimicrobial treatment is often not required, except in severe cases or immunocompromised patients. The most known source for ''Campylobacter'' is poultry, but due to their diverse natural reservoir, ''Campylobacter'' spp. can also be transmitted ''via'' water. Other known sources of ''Campylobacter'' infections include food products, such as unpasteurised milk and contaminated fresh produce. Sometimes the source of infection can be direct contact with infected animals, which often carry ''Campylobacter'' asymptomatically. At least a dozen species of ''Campylobacter'' have been implicated in human disease, with ''C. jejuni'' (80–90%) and '' C. coli'' (5-10%) b ...

Campylobacteriosis
Campylobacteriosis is an infection by the '' Campylobacter'' bacterium, most commonly ''C. jejuni''. It is among the most common bacterial infections of humans, often a foodborne illness. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, mostly including cramps, fever and pain. Symptoms and signs The prodromal symptoms are fever, headache, and myalgia, which can be severe, lasting as long as 24 hours. After 1–5 days, typically, these are followed by diarrhea (as many as 10 watery, frequently bloody, bowel movements per day) or dysentery, cramps, abdominal pain, and fever as high as 40 °C (104 °F). In most people, the illness lasts for 2–10 days. It is classified as invasive/inflammatory diarrhea, also described as bloody diarrhea or dysentery. There are other diseases showing similar symptoms. For instance, abdominal pain and tenderness may be very localized, mimicking acute appendicitis. Furthermore, ''Helicobacter pylori'' is closely ...

Foodborne Illness
Foodborne illness (also foodborne disease and food poisoning) is any illness resulting from the spoilage of contaminated food by pathogenic bacteria, viruses, or parasites that contaminate food, as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes. Symptoms vary depending on the cause but often include vomiting, fever, and aches, and may include diarrhea. Bouts of vomiting can be repeated with an extended delay in between, because even if infected food was eliminated from the stomach in the first bout, microbes, like bacteria (if applicable), can pass through the stomach into the intestine and begin to multiply. Some types of microbes stay in the intestine. For contaminants requiring an incubation period, symptoms may not manifest for hours to days, depending on the cause and on quantity of consumption. Longer incubation periods tend to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Escherich
Theodor Escherich (; 29 November 1857 – 15 February 1911) was a Germans, German-Austrians, Austrian pediatrics, pediatrician and a professor at universities in University of Graz, Graz and University of Vienna, Vienna. He discovered and described the bacterium ''Escherichia coli''. Life and achievements Family and education Theodor Escherich was born in Ansbach, as the younger son of ''Kreismedizinalrat'' (District Medical Officer) Ferdinand Escherich (1810−1888), a medical statistician, and his second wife, Maria Sophie Frederike von Stromer, daughter of a Bavarian army colonel. When Theodor Escherich was five, his mother died, and five years later Ferdinand Escherich moved to Würzburg to take up his former position as ''Kreismedizinalrat'' and married his third wife. When Theodor was 12, he was sent to a boarding school run by Society of Jesus, Jesuits in Feldkirch, Vorarlberg, Feldkirch, Austria for three years. Later, he finished secondary education in Würzburg, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antiseptics) ...
