  • Microbiology is the branch of biology that studies microorganisms, or life too small to be seen with the naked eye.Including bacteria, viruses, fungi, and pathogenic protozoa/parasites, but is not limited to studies of infectious disease-causing microorganisms.

  • Microbes as Guardians of the EarthMicrobes act as guardians of our planet ensuring that key minerals, such as carbon and nitrogen, are constantly recycled. Even though the Earth is now populated with green plants, microbes still play a crucial role in oxygenating the atmosphere and collectively they carry out more photosynthesis than plants. Microbes degrade dead organic matter, converting the organic carbon in their bodies back into carbon dioxide.Microbes are everywhereMicrobiologists have discovered that microbes can be found just about anywhere. Microbes are an incredibly diverse group of organisms and can grow in extreme environments that no other living organisms can tolerate. Bacteria have been found to thrive in volcanic hot springs, where temperatures typically reach near boiling point. At the other extreme, living bacteria have also been discovered in Antarctic deserts, where temperatures range from -15 to -30C. Bacteria can also thrive in salt flats, pools of saturated brine, where salt concentrations range from 120 to 230 grams per litre. Bacteria which live happily in these inhospitable environments have been termed extremophiles (from Latin extremus meaning "extreme" and Greek phili meaning "love").

  • Microbes and Diseases

  • Microbes and DiseaseLarge numbers of children and the elderly succumbed to diseases such as tuberculosis, diphtheria and pneumonia. At this time microbiologists had little idea about how diseases were spread, or how they could be controlled, so epidemics flourished. The "Spanish" influenza pandemic of 19181919, caused 50 million deaths worldwide - more than the total number of deaths recorded in World War One. Diarrhoeal disease was also common since people regularly ate contaminated food and drank contaminated water.Microbiology research has, therefore, been concerned with developing antibiotics and vaccines to protect the population from infectious disease. The discovery of penicillin by Alexander Flemming has saved the lives of many millions of people. The development of vaccines which protect against, diphtheria and pneumonia dramatically reduced the number of childhood deaths caused by these diseases. Children in developed countries are also routinely vaccinated against common viral infections such as measles, mumps, rubella and polio. As a direct result of the efforts of microbiologists, smallpox, once a dreadful scourge, is now officially extinct on the planet. However a vaccine against HIV, which in 2009 was reported to infect approximately 33.3 million people around the world

  • Escherichia coli There are many types of E. coli, and most of them are harmless. But some can cause bloody diarrhea. Some strains of E. coli bacteria (such as a strain called O157:H7) may also cause severe anemia or kidney failure, which can lead to death.

  • Friendly Microorganisms

  • Babies are colonised by bacteria immediately after birth. It has been estimated that the average person is colonised by 200 trillion bacteria, comprising at least 1,000 different species. This doesnt mean that we are teaming with potentially pathogenic bacteria, quite the opposite! The bacteria that call the human body home are often essential for our health and well being. Our intestines contain about 100 trillion bacteria and collectively they make up 60% of the dry weight of faeces. These intestinal bacteria play an essential role in helping us to digest food, they provide us with essential vitamins such as vitamin K and biotin and they help to prevent the growth of harmful pathogenic bacteria. The surface of our skin is also home to millions of friendly bacteria which crowd out potential pathogens and prevent them from growing. One bacterium which is abundant on the skin is Staphylococcus epidermidis which produces chemicals called bacteriocins that kill pathogenic bacteria. Friendly bacteria can also be found in our noses but many of these bacteria also carry a health warning. Neisseria meningnitidis which causes meningitis, lives in the noses of millions of people without causing disease, but if the immune system becomes weakened through ill-health then this bacteria can, almost by accident, cause disease which may result in the death of the human that has become its home.

  • Bacterial endotoxin present in the cell walls of bacteria that is released after the bacteria has died. May cause chills, fever, leukopenia, and shock depending on the bacterial species and the health of the infected person. Endotoxins are lipopolysaccharide complexes that occur in the cell wall a toxin contained in the cell walls of some microorganisms, especially gram-negative bacteria, that is released when the bacterium dies and is broken down in the body. Fever, chills, shock, leukopenia, and a variety of other symptoms result, depending on the particular organism and the condition of the infected person. Pyrogen is a substance, as a thermostable bacterial toxin, that produces a rise in temperature in a human or animal. Results of endotoxin release. From Copstead, 1995.

  • PREVENTION

    Cook Cook food thoroughly, especially meats.

    In the kitchen, wash your hands with hot, soapy water often, especially after you touch raw meat.

    Wash any tools or kitchen surfaces that have touched raw meat.

    Keep all cooking utensils and work surfaces clean

    Use only pasteurized milk, dairy, and juice products.

    Use only treated, or chlorinated, drinking water. Beware of drinking untreated water from streams, rivers and lakes.

    When you travel to countries that may have unsafe drinking water Wash your hands often, and always wash them after you use the bathroom or change diapers.
