Campylobacter Coli
''Campylobacter coli'' is a Gram-negative, microaerophilic, endospore, non-endospore-forming, spiral bacteria, S-shaped bacterial species within genus ''Campylobacter''. In humans, ''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 mucus 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 ha ...

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 language, Irish (), meaning "descendant of ''Dubhghall''". There is another possible etymology: the Anglo-Norman language, Anglo-Norman surname ''D'Oyley'' with agglutination of the French article ''de'' (cf. Disney family, Disney). It means 'from Ouilly', the name of a knight who originated from one of the places named Œuilly (other), Ouilly in Normandy, such as Ouilly-le-Tesson (Calvados, ''Oylley'' 1050), Ouilly-le-Vicomte (Calvados, ''de Oilleio'' 1279), etc. The relationship with the family Robert D'Oyly, D'Oyly is unknown. The personal name ''Dubhghall'' contains the elements ''dubh'' "black" + ''gall'' "stranger". Similar Scottish surnames, Scottish and Irish surnames, derived from the same personal name are: ''MacDougall'' / ''McDougall (other), McDougall'' and ''MacDowell (other), MacDowell'' / ''McDowell (surname), McDowell''. ...

Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

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 ...

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 25 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
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped (bacillus). But, there are also other morphologies such as helically twisted cylinders (example ''Spirochetes''), cylinders curved in one plane (selenomonads) and unusual morphologies (the square, flat box-shaped cells of the Archaean genus ''Haloquadratum)''. Other arrangements include pairs, tetrads, clusters, chains and palisades. Types Coccus A coccus (plural ''cocci'', from the Latin ''coccinus'' (scarlet) and derived from the Greek ''kokkos'' (berry)), is any microorganism (usually bacteria) whose overall shape is sphere, spherical or nearly spherical. Coccus refers to the shape of the bacteria and can contain multiple genera, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campylobacter
''Campylobacter'' is a type of bacteria that can cause a diarrheal disease in people. Its name means "curved bacteria", as the germ typically appears in a comma or "s" shape. According to its scientific classification, it is a genus of gram-negative bacteria that is motile. The germ is common in nature and in domestic animals. It is frequently found in raw food of vegetable and animal origin. Its numbers can be very high in some foods, like raw poultry. Due to their diverse natural reservoir, some ''Campylobacter'' can also be detected in the air, although not at an epidemiologically significant level. The disease that some of the species of the bacteria can cause is called campylobacteriosis. At least a dozen species of ''Campylobacter'' have been implicated in human disease, with ''C. jejuni'' (80–90%) and '' C. coli'' (5–10%) being the most common. '' C. jejuni'' is recognized as one of the main causes of bacterial foodborne disease in many developed countries. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campylobacteriosis
Campylobacteriosis is among the most common infections caused by a bacterium in humans, often as a foodborne illness. It is caused by the '' Campylobacter'' bacterium, most commonly '' C. jejuni''. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, and usually 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 ...

Foodborne Illness
Foodborne illness (also known as foodborne disease and food poisoning) is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, 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. While contaminants directly cause some symptoms, many effects of foodborne illness result from the body's immune response to these agents, which can vary significantly between individuals and populations based on prior exposure. Symptoms vary depending on the cause. They often include vomiting, fever, aches, and diarrhea. Bouts of vomiting can be repeated with an extended delay in between. This is 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 microbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Escherich
Theodor Escherich (; 29 November 1857 – 15 February 1911) was a German- Austrian pediatrician and a professor at universities in Graz and 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 Jesuits in Feldkirch, Austria for three years. Later, he finished secondary education in Würzburg, where he attended a ''Gymnasium'' (classical language high school) and took his ''Abitur'' examination in 1876 ...

Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting pathogenic bacteria, bacterial infections, and antibiotic medications are widely used in the therapy, treatment and antibiotic prophylaxis, prevention of such infections. They may either bactericide, kill or bacteriostatic agent, inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the ones which cause the common cold or influenza. Drugs which inhibit growth of viruses are termed antiviral drugs or antivirals. Antibiotics are also not effective against fungi. Drugs which inhibit growth of fungi are called antifungal drugs. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek language, Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against ...
