How do bacteria affect human lives? Essay

bacterium interact and ar a constant in our day to day lives, perhaps more than suspected. bacterium argon often thought of as problematical, besides this is untrue, there is also many types of legal bacterium. Good bacterium bunghole clear us by simply component part our digestive trunk work and percentage us in the process of fermentation. bacterium be extremely helpful in the ware of many things such as fuel and medicine. But bacteria neatway affect our production of food which, consequently, nowadays affects us. Without bacteria we wouldnt have things analogous stop, sour cream and yoghurt. Bacteria are extremely helpful in the dairy farm industry as it works inside food as a decomposer. Bacteria is needed in cheese as a starter destination, the culture grows in the take out, converting the sugar, lactose, into lactic acid giving the cheese the condemn amount of moisture and the correct acidity. Cultures are also customd in yoghurt, where it does a similar job as the one done in cheese. The culture is responsible for its taste, texture and once more, its acidity. The viscosity of the yoghurt is determined by its amount of money of polysaccharide chains.Food products other than dairy which use bacteria in their production are wine, dried meats and health food industries, where yeast, lactic bacteria and starter cultures are used. Bacteria doesnt stop luck us with food there, some bacteria defend against nocent bacteria and advocate digestion. These are all examples of bacteria benefiting forgiving life. Bacteria even help abolish toxins and help the insubordinate system maturate (1) However theyre bad bacteria often found in foods, products ilk take out buns contain less(prenominal)(prenominal) unspoiled bacteria which can be libellous. Most bacteria in milk comes from the skin of the cow and in production, save healthy cows equal less bacteria. This means in third being countries such as Uganda, where they often use unhealthy cows and goats as their briny source of milk, more bacteria is believably to be within the milk fashioning some ill and passing on disease. In places such as Britain, the milk goes through many processes making indisputable all or most damageful bacteria have been removed.An example of when bacteria are really not that beneficial to our lives isdisease causing bacteria. Bacterial pathogens can cause things like salmonella (food poisoning). Bacteria can also cause diseases like epidemic cholera. Cholera is a huge killer, killing 120,000 a year and making many others extremely sick. Its bacterium is Vibrio Cholerae which is often killed by acidic conditions in the stomach, where the hydrochloric acid and digestive juice stay. Vibrio Cholerae is often interpreted in to the body through the using up of water contaminated with fecal issue containing the pathogen and rarely the ingestion of food, also containing faecal matter with the pathogen.Carriers indeed carry t he pathogen therefore it is able to spread making it in truth loosely. Unfortunately, cholera has few or no symptoms, so it is hard to tell if soulfulness has Cholera convey it sometimes spreads unnoticed. A symptom which can be cerebrate with cholera is diarrhoea, meaning many carriers are often left being badly dehydrated. The amount of deaths that Cholera causes really reflects on how much this disease affects our lives. In 2010 and 2011, accredited areas went through the major cholera epidemics, these were Haiti, the friar preacher Republic, Central Africa and the Pacific region with Papua new-fangled wop. The major cholera epidemic started in Haiti in October 2010, and it also affected its scraggy neighbouring country, the Dominican Republic. At the end of 2011 (when the volcanic eruption was still ongoing) there were 522,335 cases of cholera and 7001 deaths had been account by the 25th of December in Haiti (2).Another example of bacteria benefiting us is bacterial v accinums. Bacterial vaccinums are rich of killed or attenuated bacteria. It seems crazy to photograph bacteria which cause very harmful diseases into the body however since they are dead they are not able to harm the body. But they do activate the immune system as it recognises it as opposed so it has to attack the bacteria. The immune system starts to produce antibodies for that particular bacteria and these phase up and build up until there is enough to destroy the bacteria, this bacteria and antibody is then are remembered by memory cells meaning that next time they are septic with that bacteria the immune system straightway recognises the bacteria therefore killing it straight away, preventing the disease and preventing the same bacterial transmittal later.One example of a bacterial vaccine is the Tuberculosis vaccine (3). The BCG vaccine is the most rough-cut vaccine. It gets to over 80% of all new bornchildren in the countries which are part of the national puerility immunisation programme. In 2011, in the countries who were hoping to immunise each and every child, the levels of use of the vaccine ranged from 53% in Equatorial Guinea and 54% in Ethiopia, to more than a much larger 99.5% in India and China, ii largely expanding countries (4). The increase of vaccinations in poorer areas of the man has lead to a much high life expectancy, greatly affecting our lives.Bacteria are majorly affecting every hit one of us in our lives, from common colds or to making cheese. The good and bad bacteria help and harm us. Overall, bacteria affects our lives more than any other and are highly beneficial and dangerous.References(1) http//www.effca.org/content/bacteria-food-production(2) http//www.who.int/gho/epidemic_diseases/cholera/epidemics/en/ (3) http//www.drugs.com/drug-class/bacterial-vaccines.html (4) http//www.tbfacts.org/bcg-tb-vaccine.html(5)
