Bakter Bakterid (Bacteria; kreeka sõnast bakteria 'kepp, sau') on kõige väiksemad (mikroskoopilised) üherakulised eeltuumsed organismid, kes suudavad iseseisvalt paljuneda ja kasvada. Baktereid uurivat teadusharu nimetatakse bakterioloogiaks. Laias mõttes on arvatud bakterite hulka kõik prokarüoodid, see on nii pärisbakterid(Eubacteria) kui ka arhebakterid ehk arhed. Kitsamas mõttes käsitletakse bakteritena vaid pärisbaktereid
composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail. Definition, composition and importance of microflora Saunders Comprehensive Veterinary Dictionary (2007) cited by the online medical dictionary (2013) defines living microorganisms as that small that they can be seen only with a microscope and that maintain a more or less constant presence in a particular area that includes bacteria, viruses, protozoa and fungi. Soil microflora more specifically, consists the following microorganisms (Bhatt et al. 2013): 1. Bacteria a) Heterotrophic bacteria, eg. symbiotic and non - symbiotic N2 fixers, ammonifier, cellulose decomposers, denitrifiers b) Autrotrophic bacteria, eg. nitrosomonas, nitrobacter, sulphur oxidizers, etc; 2. Fungus; 3. Viruses 4. Actinomycetes and stretomyces; 5. Algae eg
Infectious bovine keratoconjunctivitis Kristjan Rannaäär Veterinary medicine, 2. year, 2. group Abstract Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease and big problem in cattle farms worldwide. It is the most common ocular disease of cattle caused by bacteria Moraxella bovis. This study focuses on IBK despite having low mortality rate and complete recovery, it causes significant loss of productivity in the herds affected due to the costs of treatment and considerable impact on afflicted animals, including blindness. This research is focused on the details, such as risk factors, pathogenesis, etiology, clinical signs prevention, transmission, and treatment, which animal handlers should be aware of to minimize the harm caused by IBK
Sauerkraut Sauerkraut is finely shredded cabbage that has been fermented by various lactic acid bacteria, including Leuconostoc, Lactobacillus, and Pediococcus. It has a long shelf-life and a distinctive sour flavor, both of which result from the lactic acid that forms when the bacteria ferment the sugars in the cabbage. It is therefore not to be confused with coleslaw, which receives its acidic taste from vinegar. People of Estonia like sauerkraut very much. They definitely a great dish for Christmas, because it`s really good to eat it with potatoes or something like that. To make sauerkraut yourself you need to have: 1 kg sauerkraut, 700 g slightly salted pork, 100 g barley grits, 2 tomatoes, salt. This is how you can do it: Boil
unhealthy, in a way that is environmentally harmful and abusive of both animals and employees. The main problem is how the animals are raised, how they are slaughtered and how the meat is manufactured. Farms are controlled by big food industries. Cows are fed corn instead of grass, because corn is cheeper and makes cows obese more quickly. Because of the unhealthy environment animals are raised in, they get infected with salmonella and coliform bacteria. Salmonella and coliform bacteria infected food can lead to serious diseases and death. The chickens are raised in dark rooms, where there isn’t even room to move. They live in the middle of their own droppings and they eat each other. They are fed stuff that make them grow faster and bigger. The chickens can’t carry their own weight and fall down. Employees hit and toture them. I find horrifying how the chikens are treated as plain food not living creatures. Cows and pigs are treated in the same way.

Are MRSA infections on the rise? What are the real risks of MRSA infection for you or your child? And what can you do to protect against MRSA infection? James Steckelberg, M.D., an infectious disease specialist at Mayo Clinic, Rochester, Minn., answers these and other common questions about MRSA. What is MRSA, and why is it sometimes referred to as a "superbug"? · MRSA in hospitals. MRSA infection is caused by Staphylococcus aureus bacteria - often called "staph." Many years ago, a strain of staph emerged in hospitals that was resistant to the broad-spectrum antibiotics commonly used to treat it. Dubbed methicillin-resistant Staphylococcus aureus (MRSA), it has been called a "superbug" by the media because of its multiple drug resistance. MRSA can cause serious, sometimes fatal, infections that resist treatment with all but a few drugs - for example, vancomycin, linezolid or daptomycin

Most Meat cattle industry feeds them pellets full of hormones. While low levels of naturally-occurring Has hormones are found in various foods, many Hormones In scientists are concerned that the artificial hormones injected into cows especially cause It health problems in people who eat them. Factory farms are breeding grounds for antibiotic- resistant bacteria, known as "supergerms." On Meat could farms across America, the antibiotics that we depend on to treat human illnesses are now used make you to promote growth in animals and to keep them antibiotic alive in horrific living conditions that would otherwise kill them. Countless new strains of resistant antibiotic-resistant bacteria have developed as a result. Although some historians and anthropologists say

WATER POLLUTION THERE ARE THREE DIFFERENT WAYS THAT WATER CAN BE POLLUTED. ⦿ Surface Water Pollution - Most common type, you can visually see the pollution floating (plastic containers or oil and gasoline spills). ⦿ Ground Water Pollution – This becomes more relevant as it affects our drinking water. It become infected by toxic chemicals. ⦿ Microbial Pollution – Found in the countries who don’t have the facilities to cure the water so the bacteria and viruses grow in the water. The people have no other way of getting water so they are forced to drink it. WHAT CAUSES WATER POLLUTION? ⦿ Wastewater ⦿ Marine dumping ⦿ Industrian waste ⦿ Radioactive waste ⦿ Oli pollution ⦿ Underground storage ⦿ Global warming WHY IS IT A PROBLEM? ⦿ It causes worldwide disasters and deaths. ⦿ It may not damage our health immediately but can be harmful after long time.

than ever before. The government should take some actions and instead of talking about recession, they should improve recycling programs or take into use some new ways. Environment problem in Estonia is also water pollution. Big factories let their waste run into the rivers without cleaning it and farmers use man-made fertilizers. Their action is spoiling groundwater. Garbage wrong recycling also affects groundwater quality, because when it rains then bacteria from landfills will be washed to the groundwater. Before Tallinn citizens can drink their water, it has to pervade 15- hour cleaning process. Environmental problems don't affect our lives yet, but we have to think about it. People think that they can't make a difference, but it is wrong. Every person has to save our environment, because those little things can make a difference. Going to work or to school by bus you already save our environment
against insects and do not need toxic chemicals and productivity of genetically modified organisms is much higher, than of the usual organisms. On the other hand, geneticists recognize that intervention in a genome of live organisms can not completely be safe. In organisms are happening mutagen changes which can have strong negative impact on the human and it can be badly reflected on the human's health. Introduction in a human diet of mutagen food can lead to distribution of new pathogenic bacteria and also to increase the number of people who are suffering from food allergies. Some grades of transgene plants perniciously affect wrecker organisms and, as a result, they affect helpful organisms too. The possibility of escaping of an alien gene in the wild nature is not excluded, and it is difficult to submit what consequences can be. But it is clear that genetic pollution is capable to break natural balance and to lead to the ecological disaster which

THIRD: The market for the industrial sector which interests me is agriculture, more specifically the milk industry. Right now the situation is quite hard because the milk price has gone low which sets many smaller farms in difficult situation which often leads to shutting down the farm business. Also if there are a lot of bacteria in the milk, then the dairy industry (piimatööstus) do not take milk. A lot of help for the farmers comes from the financial support of the European Union. In a conclusion I would like to say that economy is changing all the time so we should develope ourselves all the time.

For example aerobic and anaerobic bacteria are differentiated on the bases of their need for oxygen in the metabolism. The following report is a brief overview of bacterial metabolism, that is mostly concentrated on the diffrence between anaerobic metabolism ja aerobic metabolism. Because of the complexity of bacterial metabolism the report is mainly about the fundamental diffrences in catabolism (enzymes used and energy and products that are gained) and the defenceses that are used against

experience homelessness . Homelessness usually increases during periods of economic recession () and rising unemployment, when people can no longer afford ( ) housing, and governments cut down public housing expenses. Inadequate shelter or housing creates conditions that promote disease. Without decent ( ) protection, many of the poor are exposed ( ) to severe ( ) and dangerous weather as well as to bacteria and viruses carried by other people and animals. They also are more likely to become infected with diseases carried by insects or rodents (). In arid()regions, drought leaves the poor without clean water for drinking or bathing. In temperate climates, including in the major cities of developed countries many of the homeless poor are harmed by or die of exposure ()to extreme winter cold. Inadequate shelter almost always accompanies inadequate sanitation and unhygienic practices

Often polluted water has to be freed from microorganisms. The water is than disinfected, usually by means of chlorination. Removal of dissolved solids Microrganisms are not only a threat to water; they can also be an advantage when it comes to water purification processes. They can convert harmful contaminants to harmless substances. This biological purification process usually takes a long time and it is only used for water that is polluted with contaminants that the microrganisms, usually bacteria, can convert. Physical/ chemical techniques When treatment by microrganisms is not an option we often use different treatment techniques, called physical/ chemical treatment techniques. Chemical treatment often deals with the addition of certain chemicals, in order to make sure that the contaminants change structure and can then be removed more easily. Removal of contaminants can also be done through more difficult specific chemical processes. It takes a lot of education

Microbial culture Microbiological culture is a principal tool used to diagnose infectious disease. In a microbial culture, a growth medium is provided for a specific agent. A sample taken from potentially diseased tissue or fluid is then tested for the presence of an infectious agent able to grow within that medium. Most pathogenic bacteria are easily grown on nutrient agar, a form of solid medium that supplies carbohydrates and proteins necessary for growth of a bacterium, along with copious amounts of water. A single bacterium will grow into a visible mound on the surface of the plate called a colony, which may be separated from other colonies or melded together into a "lawn". The size, color, shape and form of a colony is characteristic of the bacterial species, its specific genetic makeup

Due to its bite-based form of infection, the bubonic plague is often the first step of a progressive series of illnesses. Two other types are pneumonic and septicemic. However, pneumonic plague, unlike the bubonic or septicemic, induced coughing, and was also very infectious and allowed person-to-person spread. Bubonic plague symptoms appear suddenly, usually 25 days after exposure to the bacteria. (Wikipedia homepage: http://en.wikipedia.org/wiki/Bubonic_plague) Symptoms include: chills; general ill feeling (malaise); high fever (102 degrees Fahrenheit / 39 degrees Celsius); seizures; painful lymph gland swelling called a bubo, commonly found in the groin, but may occur in the armpits or neck, most often at the site of the initial infection (bite or scratch); pain may occur in the area before the swelling appears.

creative biogas technology to provide fuel for their citizens and there are a number of interesting applications for this gas which appeal to people who are interested in sustainable energy and the health of the environment. The basis for biogas is organic material such as food scraps and feces which are held in an anaerobic area, which can range from a storage tank which is not ventilated to a device which is specifically designed to produce gases. The conditions attract anaerobic bacteria, which start to break down the organic material, producing methane and carbon dioxide as a by-product. Another type of biogas which includes hydrogen, nitrogen, and carbon monoxide can be obtained through the gasification of biomass such as wood or rice husks, a technique which is used to manufacture gas industrially. The gases produced through anaerobic fermentation or gasification are combustible in addition to having a strong smell which makes them stand out to the human nose

Transposons act somewhat similarly to viruses and in humans are an underlying cause of hemophilia, certain cancers, and other diseases.

Broadleaf trees tend to be nutrient-demanding and their leaves bind the major nutrient bases. The autumn leaf fall provides for an abundant and rich humus which begins to decay rapidly in spring just as the growing season begins. The humus content gives soil horizons a brown colour. Temperate rainforest: This forest has nutrient-rich soil because there is a lot of dead organic matter on the ground. This dead material is being slowly digested by the fungi, insects, and bacteria that live here. Temperate Grasslands: Calcification is the dominant soil-forming process in semiarid regions. When this process works on a loess that itself is rich in calcium, the world's most fertile soils are created, the chernozems (A Russian term meaning black soil). Taiga: The low temperatures inhibit bacterial and fungal action, so the decomposition rate is low and the leaf litter relatively deep.The soil in the taiga is thin, acidic and not very nutrient rich. It also is rocky. 6
Computers help hospitals keep laboratory and medical records. Hospitals use many disposable items for safety such as plastic thermometers, and hypodermic syringes and steel needles. They are used only once, so they cannot spread infection. Scientists have also discovered all kinds of important drugs, such as antibiotics, and certain diseases, including tuberculosis and smallpox, have been almost wiped out. Antibiotics are substances, produced by living things, that are poisonous to harmful bacteria, but no the patient. The most important antibiotic is penicillin. Doctors can now also transplant organs such as the heart and the kidneys. 3. The National Health Service The National Health Service was established in Britain after World War II. The government funds it. All taxpayers contribute to its support through insurance payment. NHS made it possible that the benefits once available only for insured persons, or those who could afford it or as a form of charity, became available to
their systems. Before 1971, the term, biotechnology, was primarily used in the food processing and agriculture industries. Since the 1970s, it began to be used by the Western scientific establishment to refer to laboratory-based techniques being developed in biological research, such as recombinant DNA or tissue culture-based processes, or horizontal gene transfer in living plants, using vectors such as the Agrobacterium bacteria to transfer DNA into a host organism. In fact, the term should be used in a much broader sense to describe the whole range of methods, both ancient and modern, used to manipulate organic materials to reach the demands of food production. So the term could be defined as, "The application of indigenous and/or scientific knowledge to the management of (parts of) microorganisms, or of cells and tissues of higher organisms, so that these supply goods

on a daily basis, secondary methods account for about half, and tertiary recovery the remaining 10 per cent. Extracting oil (or "bitumen") from oil/tar sand and oil shale deposits requires mining the sand or shale and heating it in a vessel or retort, or using "in-situ" methods of injecting heated liquids into the deposit and then pumping out the oil-saturated liquid. Unconventional oil reservoirs Oil-eating bacteria biodegrade oil that has escaped to the surface. Oil sands are reservoirs of partially biodegraded oil still in the process of escaping and being biodegraded, but they contain so much migrating oil that, although most of it has escaped, vast amounts are still present—more than can be found in conventional oil reservoirs. The lighter fractions of the crude oil are destroyed first, resulting in reservoirs containing an extremely heavy form of crude oil, called crude bitumen in Canada, or
absorbs and how much of the light passes through the object. In the science and engineering world, optical density is used to determine the types of materials that make up an object. Engineers and scientists can use optical density to find out more information about the properties of an object, like the components and properties of oil, or in the medical field to examine bacteria and proteins found in a cell. 5.

Mikroevolutsioonilised muutused seisnevad peamiselt uute alleelide tekkes ja levikus. Makroevolutsiooni aluseks on uute geenide teke ja olemasolevate geenide aktiivsuse regulatsiooni muutmine.

Combination of letters( ph, kh, aeu) speak about foreign origin(nt, philology, beautiful). Sometimes it is possible to tell the immediate source of borrowing (ch): maschine is French, echo is Greek; cheese, child is Latin or native. If a word has many syllables and the stress falls on the last one, we have a foreign word (nt, picturesque, magazine, cigarette). Grammatical forms may be strange to English. We mean irregular plural forms of nouns (nt, datum data, bacterium- bacteria) 18. Assimilation. Types of assim. Degree of assim. We mean the changes that borrowings undergo(läbi elama) in English and how they adapt themselves its peculiarities. Types(?):phonetics that is changes in pronounciation. What was strange to English were replaced by other sounds (nt, phneumonia, psycology, ptolemy). Grammatical assimilation Usually borrowings lost their former grammatical features, yet some have kept their original plural inflexion (nt, thesis)
