unit -1 of Microbiology and Introduction

This ppt is covers only the important topic for the microbiology which can be useful for student studying in GNM,B.SC nursing, Post Basic nursing

1. INTRODUCTION

2. MICROBIOLOGY Micro – Small Bio – Living Logy – Study “Microbiology is a specialized branch of biology that deals with the study of organisms which are usually invisible to naked eye.”

3. HISTORY OF MICROBIOLOGY 1. Aristotle : - Father of biology - Living Organisms - Non Living organisms - Many living organisms , we can’t see. 2. Roger Bacon: - Roger Bacon invented the magnifying glass in the 13 th century.

4. 3. Louis Pasteur: - Father of Microbiology - Discovered process of Pasteurization (killing microorganisms by mild heat.) 4. Robert Koch: - Koch proved germ theory of disease (disease is caused by microorganisms) - He developed methods to obtain pure culture of microorganisms. 5. Sir Alexander Fleming: - He discovered first wonder drug antibiotic which named Penicillin.

5. BRANCHES OF MICROBIOLOGY Bacteriology – Study of Bacteria Mycology – Study of Fungi Protozoology – Study of Protozoa Virology – Study of Viruses Parasitology – Study of Parasites

6. SCOPE OF MICROBIOLOGY IN NURSING - By studying microbiology, nurses accumulate knowledge regarding different pathogens and infections, their pathogenicity, clinical feature, transmission modes are known which may be beneficial while working in hospital settings. - By recognizing the symptoms of disease, medical emergencies can be sorted out preliminarily with nursing intervention. - Microbiology helps in understanding the various modes of transmission or spread of infection, sources of infection and procedure to control the spread of these infections. - Microbiology helps in understanding the role of our body’s immunity system in defending various infections.

7. - In nursing general hygiene and cleanliness is based on the principles of microbiology. Hospital infection control practices like aseptic techniques, wound washing or general hygiene are based on principles of microbiology. - Disposal of hospital wastes is again based on principles of medical microbiology. Infection control nurses play major role in such control policies. - Study of microbiology helps nurses know about the surfaces which are susceptible to infectious agent and methods to disinfect or sterilize them.
