2. MICROBIOLOGY
• The word Microbiology was derived from Greek words mikros –
small, bios – life, logy – science.
• Microbiology is a science which deals with living organisms of
microscopic size.
• Study of microorganisms started after the discovery of
microscope by Antony Van Leeuwenhoek. He is known as father
of microbiology
• The term microbiology was introduced by a French Chemist -
Louis Pasteur, who demonstrated that fermentation was caused
by the growth of bacteria and yeast. He is known as father of
modern microbiology.

6. CHARACTERISTICS OF GROUPS OF MICROORGANISMS
• Unicellular prokaryotic or multicellular eukaryotic organisms. All algal cells contain chlorophyll
and are capable of photosynthesis. It’s study is known as Phycology.
Algae
• Unicellular prokaryotic organisms. Cell multiplication is by binary fission. It’s study is known as
Bacteriology.
Bacteria
• Unicellular or multicellular eukaryotic organisms. It includes single cell yeasts to multicellular
mushrooms. It’s study is known as MycologyFungi
• Unicellular eukaryotic organisms. It’s study is known as ProtozoologyProtozoa
• Acellular organisms. Obligate parasites. They are pathogens of plants, animals and bacteria.
Visualized by electron microscope. Cultivated in living cells. It’s study is known as Virology.

8. IMPORTANCE OF MICROBIOLOGY IN NURSING
 Microbiology is more relevant than anyother in today’s world.
 Live almost everywhere (omnipotent)
 Infectious diseases are a leading health-related issue, especially in a society
where the elderly population is increasing.
 New infectious diseases continue to emerge and be identified all the time.
 Microbiology impacts every facet of daily life

9. THE IMPORTANCE OF MICROBIOLOGY IN NURSING
 Play a major role in recycling essential elements
 Source of nutrients and some carry out photosynthesis
 Benefit society by their production of food, beverages, antibiotics
and vitamins
 Causative agents of diseases
 Global ecosystem depends on their activities
 Influence human society in many ways

10. RELEVANCE OF MICROBIOLOGY TO NURSING
 Microbiology is an essential part of nursing course.
 There has always been disease. For generations, little could be done to treat
or prevent disease.
 Infectious disease utilizes a large percentage of health care.
 Health care professionals need to understand how pathogens cause disease.
 The discovery of antibiotics began to prevent serious infection.
 Vaccination and better sanitation practices reduced the incidence of
infectious diseases.

11. RELEVANCE OF MICROBIOLOGY TO NURSING
 Nurses are involved in controlling infection in hospital, so nurses must know about
microbiology.
 To know about harmful and harmless microorganisms to human being.
 Nurses apply the microbiology knowledge in health care for drug production,
diagnosis and sterilization methods and cleanliness.
 Nurses use hot water or anti-septic as a measure to sterilize the surgical knives,
needles, scissors and other metals instruments
 Microbiology also gives knowledge to nurses on how to handle a patient and his
samples infected with communicable diseases to make free from microbes.
