TO
NURSING
•Microbiology is a subject which deals with
microbesand theirrelated concepts
•Nurses are involved in controlling infection in
hospital, so nurses must know about
microbiology.

5. PRINCIPLES
OF
MICROBIOLOGY

6. BIOCHEMISTRY

7. Biochemistryand the related
field of molecular biology are
important in understanding the
molecular basis of life and its
role in the disease
process.Microbiologyis the
study of the smallest living
organisms (micro-organisms or
microbes) and includes viruses,
bacteria, fungi, algae and
protozoa.

8. MOLECULAR BIOLOGY

9. Molecular biologyis a branch of
biochemistry which concerns
themolecularbasis
ofbiologicalactivity between
biomoleculesin the various
systems of a cell, including the
interactions between DNA, RNA,
and proteins and their
biosynthesis, as well as the
regulation of these interactions.

10. MICROBIAL GENETICS

11. Microbialgeneticsis a subject
area
withinmicrobiologyandgeneticen
gineering.
Microbialgeneticsstudies
microorganisms for different
purposes. The microorganisms
that are observed are bacteria,
and archaea. Some fungi and
protozoa are also subjects used to
study in this field.

1.Themicroorganismorotherpathogenmustbepresentinall
casesofthedisease.
2.The pathogen can be isolated from the diseased host
andgrowninpureculture.
3.The pathogen from the pure culture must cause the disease
when inoculatedinto ahealthy, susceptiblelaboratoryanimal
4.The pathogen must be reisolated from the new host
and shown to be the same as the originally inoculated
pathogen

21. CONCEPT
OF
MICROBIOLOGY

22. Microbiologyhelps
anursingprofessional to
understand the basicconceptsof
reproduction, morphology,
biochemical characteristics and
genetics.Microbiologymakes
aware about new diseases and
modern molecular identification
methods.
