The bad bacteria are the most common cause of these food borne illnesses. These bacteria are seen clearly under a microscope. The structure and the harmful effect of bacteria can be identified through a microscope. These bacteria are already present on the food we purchase and we are not aware of their existence until we experience the harmful effect such as getting sick. The most common source of these diseases is from the raw food we buy in the market because they are susceptible to contamination. Raw meat and poultry are the most common raw food that is contaminated during slaughter. Seafood and eggs can are also contaminated during harvesting and processing. Fruits and vegetables can also be contaminated with salmonella or E. coli. The contamination of these fruits and vegetables might be from the growing, harvesting, processing, storing, shipping or the final preparation.

We are not aware that even cooked foods that are left for more than two hours can attract more bacteria and can multiply quickly over a short period of time. These bacteria are not easily detected because they do not produce foul odor not change the appearance of the food. When we refrigerate food, the process only slows down the growth of bacteria but does not kill the bacteria. These bacteria are revived when the food is thawed.  The food needed to be thoroughly cooked to destroy the bacteria present on the food.

Because food borne illnesses are from the food we eat so the most common symptoms are abdominal cramps, nausea, vomiting, diarrhea, fever and dehydration. These food borne illnesses pose greater risk on young children, pregnant women and older adults because they have weaker immune system. There are also some complications that can cause serious infections such as abortion and death and they are caused by these micro organisms such as listeria monocytogenes and clostridium botulinium.  E. coli can also cause the disease called Hemolytic uremic syndrome (HUS) and this can lead to kidney infection and sometimes death. HUS usually affects children from ages 1-10. This disease can be from contaminated food and beverages, undercooked beef, contaminated water and even contact with infected person can cause this disease. Children must be observed of the symptoms of HUS. The most common symptoms of HUS are diarrhea which can be bloody, vomiting and abdominal pains. The development of HUS is from 5 to 10 days and this disease can last up to 15 days and can be considered as fatal.

The other symptoms of HUS are fever, lethargy and paleness and this also leads to renal failure. Acute renal failure can cause kidney not able to remove the waste products from the blood and unable to transform them into urine. It is advised that the child should see a doctor if he is experiencing diarrhea for the past 3 days with fever, blood in stools, vomiting, dehydration and shallow breathing. These food borne diseases are diagnosed through laboratory testing and by studying the bacteria under a microscope. Diagnostic test of these bacteria can also suggest cure for the bacterial toxins, viruses and parasites in the body. Some food borne disease can be cured by water therapy or increased fluid intake, but serious cases need medical treatment such as hospitalization.

Prevention is still the best cure for food borne illnesses. To prevent food contamination, food should be cooked properly and must be kept in clean area. Clean foods before you refrigerate them to avoid growth of bacteria. Other cure can be from food irradiation which is in the form of gamma rays and electron beams that kills loving bacteria to prevent food borne illnesses. Food irradiation is used for wheat, potatoes, spices, pork, poultry, fresh fruits and other dehydrated products. According to scientists who study food borne diseases, these food borne pathogens are also caused of chronic diseases that can permanently destroy or organs. They also studied that these food borne illnesses trigger chronic health conditions. These serious health conditions are arthritis, bowel diseases, kidney failure and autoimmune disorders.

Study shows the sources of food borne illnesses, the symptoms and the bacteria that caused these diseases. Raw and undercooked meat and poultry causes abdominal pain, diarrhea, nausea and vomiting and the bacteria present are campylobacter jejuni, e.coli, monocytogenes and salmonella. Unpasteurized milk and dairy products like soft cheese causes nausea, vomiting, fever, abdominal pain and diarrhea which are from the bacteria listeria monocytogenes, salmonella, shigella, staphylococcus aureus, and c. jejuni. Raw and undercooked eggs that are used when we make salad dressing, cake icing and ice cream can cause nausea, vomiting, fever, abdominal pain and diarrhea if contaminated with salmonella enteriditis. Shellfish that are raw and undercooked with the bacteria vibrio vulnificus, vibrio parahaemolyticus can cause shills, fever and can make the person collapse.

Canned goods and smoked or salted fish can also pose threat if C. botulinium is present, symptoms of this can cause double vision, difficulty in swallowing, speaking and breathing. If the following symptoms are experienced it is advised to seek medical help immediately. Contaminated water can cause bloody diarrhea, nausea and vomiting because of the presence of e.coli, monocytogenes, salmonella, shigella, yersinia entercolotica, viruses and parasites. To prevent these food borne diseases from attacking us, we need to keep the food clean all the time. Prevention is still the best cure. Read more on this topic

Bacteria under a microscope are one celled organisms that get their food from the environment to survive. Most bacteria feed on human body. These bacteria are inside our body cause infections and diseases. The most common diseases from bacteria are sore throat, ear infections, cavities and pneumonia. But not all bacteria are bad, there are some bacteria that are good and they keep the environment balance. These good bacteria can be found in our intestines. They help us the digest the food and distribute the nutrients all over our body and out to waste what is not needed by our bodies. Good bacteria are also used by doctors and scientists to make medicines that cure diseases.

Viruses need another living cell in order to survive. These viruses can not survive very long if they do not have a host. The host of these viruses can be from a plant, animal or human beings. The virus inside the body can cause sickness such as chickenpox, measles, flu and other diseases that are transmittable.  To avoid getting sick from these viruses, it is advised to wash regularly because these viruses can be found anywhere.

Fungi are multi celled organisms that look like plants but unlike plants these fungi can not make their own food. These fungi can get their food from plants, animals and human.  Fungi structure can be seen under a microscope. They are so small and they usually live in damp and warm places. Fungi are less harmful compared to bacteria and viruses. Fungi can cause athlete’s foot and molds on our bread.

Protozoa are one celled organisms that can be found in moist area. These kinds of germs spread through water. The most common diseases caused by protozoa are diarrhea, nausea and other stomach pain. The germs inside our body invade us and eat all the nutrients and energy. They also produce body toxins that are poison to the body. These toxins can cause us fever, rashes, cough and diarrhea. Doctors find out about the harmful effects of bacteria by studying the samples sent to the laboratory. Doctors and scientists conduct series of test to the samples submitted to them under a microscope.

Bacteria under a microscope show the damage caused by these germs to our body. The doctors can tell how these tiny organisms cause sickness to humans.  Most germs spread without our notice. When somebody sneezes on the bus, people beside the person might contract the germs from that person. Germs also spread through saliva, sweat and blood. We can easily acquire germs when we come in close contact with people who are sick. To protect ourselves from these germs most doctors advise constant washing and taking vitamins for protection.

Bacteria can also feed on almost everything from sugar, starch, sulfur and iron. There are also some bacteria species that can withstand 1,000 times blast of radiation that can kill human beings.  Bacteria are under prokaryotes which DNA are not enclosed by nucleus. Other organisms are fall under eukaryotes because of the presence of nuclei. The bacteria under a microscope will show us the cell wall, the shape and the movements of these bacteria. By knowing more about bacteria we can figure out how they are able to help us and we can also prevent the dangerous ones to cause us harm. Most of us question the existence of these bacteria. How long have they been on earth? Scientists conduct research that proves bacteria existed before humans.

They might not be visible to the eyes but they existed. Bacteria and Archaea are the earliest inhabitants of this planet. They live for billions of years and they can survive extreme conditions. According to research bacteria play an important role in shaping the planet because they are responsible of developing photosynthesis. Bacteria like dinosaurs leave traces behind. The only difference is the size of the fossils they leave behind. Dinosaur fossils can be dug by geologists and big fossils can be found but bacteria can only be seen through a microscope.

Bacteria under a microscope can distinguish the age of the bacteria found. The existence of bacteria was discovered million of years ago but the study of them was only conducted in the early 1800’s. Cyanobacteria fossils are among the oldest bacteria that live for about 3 million years.Cyanobacteria’s photosynthesis gave way in producing algae and plants. It is believed that cyanobacteria develop in water; they can also produce more oxygen than we breathe. Bacteria are responsible for a lot of things. The cheese we eat everyday is produced by bacteria on the milk.

The beer we enjoy was also a product of bacteria. The good things that we benefit from bacteria are not as popular as the harmful effects the bacteria we all know. The disease causing bacteria that can kill us is usually the main focus. Scientists nowadays are examining more and more bacteria under a microscope to discover more benefits that we can get from bacteria. They are also discovering cure to these harmful diseases that plagues humans. Original article

Some diseases that are caused by bacteria are tetanus, pneumonia, syphilis, tuberculosis and a lot more. Antibiotics can treat these diseases, however there are some bacteria that can’t be killed, they only be prevented. Prevention of these bacteria can be possible by using antiseptics, disinfectants and sterilization.

The beneficial bacteria are also called good bacteria. They are the bacteria that help produce the food we eat. They also help in keeping the soil fertile. Bacteria are also responsible in helping us digest our food.  The role of bacteria in our digestive system is converting the milk protein to lactic acid. The good bacteria in our digestive system also help prevent the growth of harmful bacteria.  Read the entire article

Bacteria can survive in any environment. There are three groups of bacteria. The first group of bacteria under a microscope is called the Aerobic bacteria, they survive because of oxygen and without it, they will not be able to survive and exist. The second group of bacteria under a microscope is called the anaerobic bacteria. These bacteria can be found underwater and they are those can cause food poisoning.  The last group of bacteria under a microscope is called the facultative anaerobes. These bacteria live better with the presence of oxygen, however, without it; they can still continue to exist.

Bacteria can also be identified by their energy source. The Heterotrophs are bacteria under a microscope that obtain their energy from the organic compounds that they acquire from the environment, an example of these bacteria is the saprobic bacteria that we can find in decaying material. Another group of bacteria that are fueled by light energy is called the autotrophs. Autotrophs make their own food by using carbon dioxide.

Bacteria, though most of us perceive to be dangerous, is also considered important in the ecosystem we are living in. Bacteria provide balance in the ecosystem. Our ecosystem survives mainly because of the bacterial activity both on land and on water. Bacteria play an important role in the nutrients cycle of carbon, nitrogen and sulfur.

Bacteria that act as decomposers help deplete the carbon dioxide in the atmosphere by quickly decomposing the dead and rotting organisms. This might sound so simple but without carbon dioxide, photosynthesis won’t exist and plants will have no food to survive. This simple process is very important for the survival of both plants and animals. The carbon dioxide from a dead organism is no longer available for living things. This is where decomposition would take place. Decomposition is breaking down the nutrients available from the dead organism and releasing it back to the environment, and this would not be possible without the help of bacteria. Bacteria, like humans also play an important role in the environment. They might be seen visibly but they do exist. Here is a link to the article
