what good roles do microorganisms play in diseases?
374140
the best known good role is the normal flora which is the microbes of the skin, intestine.. that are naturally thier some produce antibiotics that kills pathogenic bacteria and some produce vitamins..some lactobacilli produce lactic acid in the vagina and prevent the growth of fungi like Candida albicans

Infants receive "beneficial" bacteria from mother's milk. By keeping a healthy balance of intestinal flora, this will enhance the child's immune system, aid in digestion and regulate the bowel movements.

Although there are many opportunities in these areas, I will only highlight two, since I have experience in those areas.  The first is a Clinical Laboratory Scientist (aka-Medical Technologist).  These are the people who generally work in hospital labs, performing the various tests on body fluids that doctors order.\n\nMed techs can choose to work only in the area of Microbiology in the lab.  They culture patient samples and identify any organisms that may grow from those samples.  They also perform susceptibility testing on organisms to help let the doctor know which drugs would work best to treat the patient.  (Med techs can also specialize in Mycology (fungi) and parasitology.)\n\nImmunology is another area that med techs can work in.  Here, they test patients' blood for antibodies in order to diagnose various (often viral) diseases.\n\nAlso, there is also a demand in the field of infectious disease epidemiology.  In this area, epidemiologists try to find the cause, source, etc. of various infectious agents as well as try to find a way to prevent occurences of infectious disease.\n\nSo, that's about all I can tell you in a nutshell.  I hope that helps.

microbiology is the emerging field of interest.\nIt can and plays a very important role in the pharma as we can force them to produce certain materials of our interest beyond their natural tedencies. \nnow a days genetic engineering and microbiology can both be used together for further increasing the scope.

It is the branch of biology that studies microorganisms and their effects on human.living things too small to be seen with unaided eye are called microorganisms.they are important in the maintenance of an ecological balance on earth.\n        In 1665,Robert hooke introduced the cell.in 1673,Anton van leewenhoek used a simple  microscope to observe microorganisms.in 1668,Francesco redi demonstrated maggots appear on decaying meat only when flies are able to lay eggs on the meat.in 1745,John needham demonstrated that microorganisms could arise spontaneously from heated nutrient broth.in 1765,Lazzaro spallanzani repeated needham's experiment and suggested his results were due to microorganisms in the air entering his broth.in 1858,Rudolf virchow described concept of biogenesis .living cells can  arise only from preexisting cells.in 1861, Louis pasteur demonstrated microorganisms are in the air everywhere and offered proof  of biogenesis.\n          Rapid advances in the science of microbiology were made between 1857 and 1914.Pasteur found that yeast ferment sugars to alcohols and that bacteria can oxidize the alcohol  to acetic acid.A heating process called pasteurization is used to kill bacteria in some alcoholic beverages  and milk.\n\nmodern developments:\n          study of AIDS,analysis of action of interferons and the development of new vaccines is the current research in microbiology.new techniques in molecular biology and electron microscopy have provided tools for advancement of our knowledge of virology.development of rDNA technique ,has helped advance all areas of microbiology.

Blood's role in the body is three fold: First, it acts as a transort system for nurtients and such to reach the different parts of the body. Secondly as a defence system, where lymphocytes are active in controlling pathogens that enter the body (such as bacteria, viruses, fungi, etc). Lastly, the blood acts as a sealant. When there is damage to the body, the platelets in the blood seal up the wound.\n\nBlood is very important to the body. Without it, you wouldn't exist.

bacteria rots milk until it becomes YOGHURT and it can rot further until CHEESE is made!\n\nAlso don't forget VACCINATIONS... these actually contain a small amount of the disease in question so that your body can fight it (without becoming ill).  If ever you get infected for real your body now knows what to do and fights it off!\n\nYEAST is used to make bread and the brewing of beer\n\nhope this helps! :-)

E.\nBecause bacteria can obtain nutrition chemically, they can live in conditions that no-one thought possible, for example in volcanic vents at the bottom of the ocean.

health? . . . diseases and conditions are for infectious bacteris and that sort of fun stuff . . . so i guess health if that helps you.

microbiology is a subject with great potential. Micrbes are being used from everything from "eating up oil" to producing human insulin!\nThough the subject has just too many applications in oil industry, agriculture, pharmacy, chemical industry, biotech etc. etc. perhaps the best applications would be in the pharmacy sector where microbes are  both friends and foes. \n\nOn one hand microbes are used for production of many drugs penicillin, chloromycetin, soframycin, human insulin, botox, many protiens, enzymes and hormones. On the ther hand the harmful ones are carefully studied and screened from the drugs manfactured. So a microbiologist has applications in both R&D, Production and Quality Control aspects.\n\nResearch is also being done in biotech, where microbes are being modified to produce more nitrogen, provide disease resistence, improve vigour  in plants , etc. etc. \n\nBut you must do an M.Sc. then Ph.D.

There are many types of microbiological problems, and more than one solution for each.\n\nFor example, an infection caused to a bacteria (like the flu) is such a problem. A possible solution is an antibiotic from your doctor: it kills the bacteria and you get your health back.

The use of microorganisms, such as bacteria or yeasts, or biological substances, such as enzymes, to perform specific industrial or manufacturing processes. Applications include the production of certain drugs, synthetic hormones, and bulk foodstuffs as well as the bioconversion of organic waste and the use of genetically altered bacteria in the cleanup of oil spills. \n\nThe application of the principles of engineering and technology to the life sciences; bioengineering. \nSee ergonomics.

Fungus is an important element in the decaying process.Fungus with the right moisture and temperature helps to break down organic matter into micro nutrients and these nutrients supply other organisms with nourishment . Fungus also produce other chemical compounds that can be used as medicine ,plus some fungus can be used for food.

Procedures used to prevent the introduction of fungi, bacteria, viruses, mycoplasma or other microorganisms into cell, tissue and organ cultures. Although these procedures are used to prevent microbial contamination of cultures, they also prevent cross contamination of cell cultures as well. These procedures may or may not exclude the introduction of infectious molecules.
