How do bacteria affect human lives? Essay

Bacteria interact and ar a constant in our mean solar day to day lives, perhaps much than suspected. Bacteria are often mentation of as bad, as yet this is untrue, there is also many a(prenominal) types of good bacterium. well(p) bacteria rump benefit us by simply dowery our digestive body work and helping us in the cultivate of fermentation.Bacteria are extremely helpful in the production of many things such as fuel and medicine. exclusively bacteria directly change our production of food which, therefore, directly affects us. Without bacteria we wouldnt have things standardised cheeseflower, sour cream and yoghourt. Bacteria are extremely helpful in the dairy farm industry as it works within food as a decomposer. Bacteria is needed in cheese as a starter culture, the culture grows in the take out, converting the sugar, lactose, into lactic acid giving the cheese the correct amount of moisture and the correct acidity. Cultures are also utilize in yoghurt, where i t does a similar job as the one through with(p) in cheese. The culture is responsible for its taste, texture and once more, its acidity. The viscosity of the yoghurt is determined by its quantity of polysaccharide chains.Food products other than dairy which exercise bacteria in their production are wine, dried meats and health food industries, where yeast, lactic bacteria and starter cultures are used. Bacteria doesnt stop helping us with food there, some bacteria adjudge against harmful bacteria and aid digestion. These are tout ensemble examples of bacteria benefiting kind-hearted life. Bacteria even help drop off toxins and help the immune system mature (1) However theyre bad bacteria often give in foods, products alike milk can contain less unspoiled bacteria which can be harmful. Most bacteria in milk comes from the skin of the cow and in production, however healthy cows relate less bacteria. This means in third world countries such as Uganda, where they often use un healthy cows and goats as their main fount of milk, more bacteria is likely to be within the milk do some ill and passing on disease. In places such as Britain, the milk goes through many processes make sure all or most harmful 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 Cholera. Cholera is a huge killer, killing 120,000 a year and make many others extremely sick. Its bacterium is Vibrio Cholerae which is often killed by acerbic conditions in the stomach, where the hydrochloric acid and digestive juice stay. Vibrio Cholerae is often interpreted in to the body through the ingestion of water contaminated with fecal matter containing the pathogen and rarely the ingestion of food, also containing faecal matter with the pathogen.Carriers then(prenominal) carry the pathogen therefore it is able to spread making it very deadly. Unfortunately, cholera has few or no symptoms, so it is hard to tell if mortal has Cholera meaning it sometimes spreads unnoticed. A symptom which can be linked with cholera is diarrhoea, meaning many carriers are often remaining being severely dehydrated. The amount of deaths that Cholera causes really reflects on how oftentimes this disease affects our lives. In 2010 and 2011, certain areas went through the major cholera epidemics, these were Haiti, the Dominican Republic, Central Africa and the Pacific region with Papua New Guinea. The major cholera epidemic started in Haiti in October 2010, and it also affected its close neighbouring country, the Dominican Republic. At the end of 2011 (when the outbreak was still ongoing) there were 522,335 cases of cholera and 7001 deaths had been reported by the 25th of December in Haiti (2).Another example of bacteria benefiting us is bacterial vaccines. Bacterial vaccines are full of killed or attenuated bacteria. It seems wacky to inject 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 inappropriate so it has to attack the bacteria. The immune system starts to produce antibodies for that particular bacteria and these build 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 conterminous time they are infected with that bacteria the immune system this instant recognises the bacteria therefore killing it straight away, preventing the disease and preventing the same bacterial infection later.One example of a bacterial vaccine is the terabit vaccine (3). The BCG vaccine is the most common 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 hopi ng to vaccinate 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, two generally expanding countries (4). The increase of vaccinations in poorer areas of the world has lead to a much high life expectancy, greatly affecting our lives.Bacteria are majorly affecting every single 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)
