Bacteria interact and are a constant in our everyday lives, probably more than thought. Bacteria are usually thought of as poor, however this is wrong, there is also a number of ‘good’ bacteria. ‘Good’ bacteria can benefit us by simply assisting our gastrointestinal tract work and helping all of us in the process of fermentation.

Bacteria are extremely helpful in the production of several things such as gasoline and remedies. But bacteria directly affect the production of food which usually, therefore , straight affects all of us.

Without bacteria we wouldn’t have things such as; cheese, bitter cream and yoghurt. Bacterias are extremely helpful in the dairy industry since it works within food as being a decomposer. Bacterias is needed in cheese being a starter culture, the culture grows inside the milk, switching the sweets, lactose, in to lactic acid giving the cheese the correct amount of moisture plus the correct level of acidity. Cultures double in yogurt, where it can do a similar task as the one done in cheese.

The culture is liable for its preference, texture and when more, the acidity. The viscosity with the yoghurt is dependent upon its level of polysaccharide organizations.

Food products aside from dairy designed to use bacteria within their production are; wine, dried meats and health meals industries, where yeast, lactic bacteria and starter ethnicities are used. Bacterias doesn’t quit helping all of us with food there, a lot of bacteria prevent harmful bacteria and aid digestive function. These are most examples of bacteria benefiting individual life. Bacteria even help eliminate toxins that help the immune system adult (1)! On the other hand they’re awful bacteria typically found in food, products like milk can easily contain significantly less beneficial bacterias which can be hazardous. Most bacteria in dairy comes from the skin of the cow and in creation, however healthy and balanced cows equal less bacterias. This means in third world countries such as Uganda, where they often use detrimental cows and goats his or her main supply of milk, even more bacteria will probably be within the dairy making a few ill and passing upon disease. In places including Britain, the milk experiences many techniques making sure any most parasites have been eliminated.

An example of when ever bacteria are actually not that beneficial to our lives is disease creating bacteria. Bacterial pathogens may cause things like salmonella (food poisoning). Bacteria can also cause diseases like Cholera. Cholera will be a major killer, getting rid of 120, 1000 a year and making many more extremely sick. Its bacterium is Vibrio Cholerae which can be often murdered by acidulent conditions inside the stomach, where hydrochloric acid and intestinal juice stay. Vibrio Cholerae is often consumed in to the body through the ingestion of water contaminated with faecal matter that contain the virus and hardly ever the consumption of meals, also that contains faecal matter with the pathogen.

Service providers then take the pathogen; therefore it is able to spread making it extremely deadly. However, cholera offers few or any symptoms, it is therefore hard to see if an individual has Cholera meaning this sometimes spreads unnoticed. An indicator which can be linked with cholera can be diarrhoea, which means many carriers are often remaining being severely dehydrated. The quantity of deaths that Cholera triggers really reflects on how much 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 as well as the Pacific location with Papua New Guinea. The major cholera epidemic were only available in Haiti in October 2010, and it also afflicted its close neighbouring nation, the Dominican Republic. At the end of 2011 (when the outbreak was still ongoing) there was 522, 335 cases of cholera and 7001 deaths had been through the twenty fifth of January in Haiti (2).

One more example of bacterias benefiting all of us is bacterial vaccines. Microbe vaccines are full of killed or attenuated bacteria. It seems crazy to utilize bacteria which cause very dangerous diseases in to the body; on the other hand since they are lifeless they are unable to harm the body. But they do activate immune system as it recognises it since foreign so it has to attack the bacterias. The immune system begins to produce antibodies for that particular bacteria and these increase and build up until there is enough to eliminate the bacterias, this bacterias and antibody is then will be remembered by memory skin cells meaning that the very next time they are afflicted with that bacteria the immune system immediately recognises the bacteria therefore killing this straight away, protecting against the disease and preventing a similar bacterial infection later.

One example of any bacterial vaccine is the Tuberculosis vaccine (3). The BCG vaccine is among the most common shot. It gets to over many of these of all new born children inside the countries which are part of the national childhood prophylaxie programme. This summer, in the countries who were hoping to vaccinate every child, the levels of use from the vaccine went from 53% in Equatorial Guinea and 54% in Ethiopia, to higher than a much larger 99. 5% in India and China, two largely expanding countries (4). The increase of vaccinations in poorer parts of the world offers lead to a much higher life expectancy, greatly impacting our lives.

Bacterias are extremely affecting every one of us inside our lives, coming from common colds or to making cheese. The ‘good’ and ‘bad’ bacteria help and harm all of us. Overall, bacterias affects existence more than some other and are remarkably beneficial and dangerous.
