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.
Concentrating on microbiology is incredibly noteworthy in the present world. Infections are a key health issue today, especially in communities where the numbers of occupants who are the elderly are constantly going up. Through microbiology, new irresistible ailments that develop can be accurately diagnosed. Microbiology influences every part of each day life including the air we breathe in, the foods we take in, the clinics we go for treatment in the occasion of an negative event like sickness or accident and natural related calamities that happen out of the blue.
There has always been infectious diseases that utilizes a large percentage of our health and therefore health care professionals need to understand how pathogens cause diseases. For a time, most infections diseases were thought to be under control. However, diseases thought to be under control are reappearing. For example pathogens are showing increasing resistance to antibiotics. Interest in bio-terrorism has progressed from fiction to fact. With these, a fundamental understanding of microbiology is very relevant to help curb this situation.
Only a fraction of pathogens cause infectious diseases in humans. The potential of a pathogen to cause disease is referred to as degree of virulence. Pathogens can therefore be categorized according to their degree of virulence. Some fungi and most bacteria are part of the normal microbial flora of the body and therefore most of the times they are completely harmless. Some of these organisms provide important services to the body but in other circumstances they become pathogens. When this happens, they are referred to as opportunistic pathogens and posses a mild degree of virulence.
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.
Many successful ways are available to counter infections caused by pathogens. These include antibiotics, disinfectants and antiseptics. Antibiotics act selectively to kill the diseases causing micro-organisms but not harm patient because they are toxic. Treatments are easier for bacterial infections compared to viral diseases.
Microbiology is not all about about infectious illnesses. A few microorganisms are useful to us as they can reuse components of the soil, change elements of the environment to useful products and give back of carbon-dioxide. Microorganisms can also be made use of in bio-remediation. They are additionally utilized as a part of reusing waste, for example, waste water amid sewage treatment. In Biotechnology, microbes can be utilized to create new medications to improve treatment techniques.
