DNA
Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known aspolynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either guanine (G), adenine (A), thymine (T), or cytosine (C)—as well as a monosaccharidesugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bondsbetween the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA.

Helicobacter pylori
Helicobacter pylori) © Helicobacter pylori are a spiral shaped bacteriabelonging to the Proteobacteria family.It is a pathogenic bacteria living in the mucous membrane of gastrointestinal tract of humans.Helicobacter pylori contain unpolar flagella`s. It was rediscovered in 1983 by the Nobel price winner Barry Marshall and Robert Warren. Helicobacter pylori can couse duodenal-and gastric wounds and cancer. The transmission mode is direct- and indirect contact (fecal-oral). Symptoms are dyspepsia, diarrhoea and abdominal pain.Disease can most of the time be treated effectively with antibiotics. There is no vaccine.
Pseudomonas
Pseudomonas aeruginosa belongs to the Pseudomonas family. It is a Gram negative rod with unipolar flagella’s. Pseudomonas aeruginosa is an opportunistic bacteria and part of the normal flora of the gastrointestinal tract of humansand animals. It is found in soil, water and grow in moist environments. It colonizes skin, gastrointestinal tract and airways of humans and can cause infectionsmostly in immunocompromised patients. Pseudomonas aeruginosa frequently cause nosocomial infections.The transmission mode is direct-and indirect contact. Disease caused by Pseudomonas aeruginosa can be treated with antibiotics.

E.coli
This is a Gram-negative rod belonging to the Enterobacteriaceae family. The bacteria was first detected in 1940 (EPECH).The E. coli are mobile bacteria because of flagellas on the cell surface. It is found in large amounts in the colon of humans and animals,usually not a pathogenic micro-organism. E. coli can cause infections such as urinary tract infections, diarrhoea, and neonatal meningitis and wound infections. The transmission is by direct- and indirect contact (faecal-oral), through contaminated food and poor hygiene. Infections can be treated with antibiotics.

HIV
Human Immunodeficiency Virus(HIV)is a virus in the Retroviridae family. HIV is pandemic and it is estimated that approx 60 million are carriersof the virus globally. The virus is found in blod and bodyfluids that contain blod. The transmission mode is Through sexual contact, inoculation, contactwith infected blod and bodyfluids, perinatal transmission during birth and breast feeding. Symptoms can be flulike, pharyngitis, fever, enlarged lymph nodes, fatigue, rash, headache and diarrhea. If infected with the virus, there is no cure. However, new antivirual Treatment is available .
H1N1
Novel Influenza A (H1N1) © Influenza virus is a circular virus. There are three sero types of influenza virus (A, B, C). Type A is connected to wid- espread epidemics occurring annually. Pandemics (e.g Spanish flu 1918-19) are rare. Influenza type A has several subtypes, classified according to antigenic properties on the surface of the virus glycoproteins (spikes), haemagglutinin (H) and neuraminidase (N). Humans are the primary reservoir for human infections. On June 11, 2009, the (WHO) signaled that a global pandemic of novel influenza A (H1N1) was underway by raising the worldwide pandemic alert level to 6. Transmission mode is airborne, incubation period varies from 1- 7 days. Clinical symptoms are high fever, body aches, headache, sore throat, dry cough, runny or stuffy nose, general fatigue, diarrhea. Secondary bacterial infections, e.g pneumonia,
Tuberculosis
Mycobacterium tuberculosis© Mycobacterium tuberculosis is a Gram- positiv rod belonging to the Mycobacterium family. It was first detected in 1882. The highest incidence in Norway was in 1900.Globally Mycobacterium tuberculosis is pandemic.Approximately 30 % of the world population is infected and a mortality of more then 2 million annually. The transmission mode is droplet and airborne. Symptoms are vague, flulike symptoms, with fever, increased production of airway secretions, weight loss, night sweat, fatigue. The disease can be treated with combination therapy of several antibiotics. Vaccine is available but mostly given to high risk groups.

Ebola
Ebola virus disease (EVD) Ebola hemorrhagic fever (EHF),is a disease of humans and other primates caused by an ebolavirus. Symptoms start two days to three weeks after contracting the virus, with a fever, sore throat,muscle pain, andheadaches. Typically, vomiting, diarrhea, and rash follow, along with decreased function of the liver and kidneys. Around this time, affected people may begin to bleed both within the body and externally.The virus may be acquired upon contact with blood or other bodily fluids of an infected human or otheranimal. Spreading through the air has not been documented in the natural environment.Fruit bats are believed to be a carrier and may spread the virus without being affected. Once human infection occurs, the disease may spread between people as well. Blood samples are tested for viral antibodies, viral RNA, or the virus itself to confirm the diagnosis.[1]No
DNA barcode
DNA barcoding is a taxonomic method that uses a short genetic marker in an organism's DNA to identify it as belonging to a particular species. It differs from molecular phylogeny in that the main goal is not to determine patterns of relationship but to identify an unknown sample in terms of a preexisting classification.Although barcodes are sometimes used in an effort to identify unknown species or assess whether species should be combined or separated,the utility of DNA barcoding for these purposes is subject to debate. The most commonly used barcode region, for animals, at least, is a segment of approximately 600 base pairs of the mitochondrial gene cytochrome oxidase I (COI). Applications include, for example, identifying plant leaves even when flowers or fruit are not available, identifying insect larvae (which may have fewer diagnostic characters than adults and are frequently less well-known),
Grid
A grid cell is a type of neuron in the brains of many species that allows them to understand their position in space.[1][2][3][4][5][6] Grid cells derive their name from the fact that connecting the centers of their firing fields gives a triangular grid. Triangular grids of synchronized neurons were predicted by William H. Calvin in his 1996 monograph The Cerebral Code on the basis of recurrent collateral branches in neocortical pyramidal neurons that had synaptic clusters at a standard spacing.[7] Grid cells were discovered in 2005 by Edvard Moser, May-Britt Moser and their students Torkel Hafting, Marianne Fyhn and Sturla Molden at the Centre for the Biology of Memory (CBM) in Norway. They were awarded the 2014 Nobel Prize in Physiology or Medicine together with John O'Keefe for their discoveries of cells that constitute a positioning system in the brain.
