Microbiology is a science that deals with the study of living organisms that cannot be seen by the naked eye such as bacteria, protozoa parasites, viruses and fungi. These organisms can only be seen with the aid of a microscope. Studying about Microbiology is vital for biology related professional fields.
The study of microbiology is very relevant in the present world. Infectious diseases are a leading health-related issue, especially in societies where the population of the elderly is increasing. Through microbiology, new infectious diseases continue to emerge and be identified all the time. Microbiology impacts every facet of daily life including the air we breathe, the food we eat, the hospitals we go for treatment in case of illness or injury and natural disasters that occur without warning.
On all occasions, there has been infections that take advantage a huge part of human health and in this way health experts need to see how pathogens cause sicknesses. For a period, most maladies were thought to be under control. Even though, maladies once thought to be checked are returning. For instance pathogens are becoming more impervious to antibiotics. Enthusiasm for bio-terrorism has advanced from fiction to reality. With these, a major comprehension of microbiology is extremely significant to help check this circumstance.
Only a small fraction of pathogens are behind ailments in humans. The ability of a pathogen to cause an ailment is alluded to as its level of virulence. Pathogens can thus be categorized by the level of virulence they have. Some fungi and most bacteria living organisms are only an integral part of the the biological systems of our bodies. Along these lines the larger part of the times they are absolutely harmless to our bodies. Some of these microorganisms oversee the body with key administrations. However in diverse circumstances they get the chance to be pathogens. Right when this happens, they are considered as opportunistic pathogens and cause damage to a little extent.
Some pathogens are always highly virulent and therefore associated with disease pathogens. They can be looked at from three perspectives. For example Epidemiology, Pathogenesis and host defense. Epidemiology studies factors determining the frequency and distribution of disease. These include how pathogens get into the body, stays in the body, defeat the host defense, damage the host and be transmitted. Providing the best care for infected individuals therefore requires a good understanding of the five requirements for infection.
Pathogenesis refers to the various methods employed by infectious micro-organisms to accomplish infections. For example bacterial pathogens can produce enzymes that can digest and toxins and viral pathogens can kill the host cells. On the other hand, host defense refers to how the host reacts to the entry of pathogens into the body. The outcome of this reaction depends on success or failure of the host's defense. Failure of the host defense therefore leads to infection.
Numerous effective ways are accessible to counter contamination brought about by pathogens. These incorporate use of disinfectants, germicides and antibiotics. Antibiotics act specifically to eliminate the micro-organisms causing the illness while not hurting the patient considering that they are poisonous. Medical treatment for bacterial infections are less demanding in contrast to viral illnesses.
Microbiology is not just about infectious diseases. Some microbes are beneficial to humans as they can recycle vital elements in soil, convert elements in the environment to usable forms and return carbon-dioxide to the atmosphere. Microbes can also be used for bio-remediation. They are also used in recycling waste such as waste water during sewage treatment. In Biotechnology, bacteria can be used to produce new drugs and viruses to gene therapy strategies.
