PREFACE
The textbook of
‘Pharmaceutical Microbiology’
specifically aims at the ever demanding
thoughtful need of an absolutely well-documented compilation of factual details related to : theoritical
principles, classifications, diagramatic profiles, graphic presentations, critical explanation, latest examples
for the Pharmacy Degree (B. Pharm.,) throughout the Indian Universities, SAARC-countries, and similar
curricula adopted abroad.
Modern invigorative society, based on the overwhelming and overemphasized broad-spectrum
importance
vis-a-vis
utilities of
‘Microbiology’
profusely gets benefited from the intricate species of
scores of microorganisms in several ways and means, namely :
antibiotics, vaccines, enzymes, vitamins
etc. Nevertheless, a quantum-leap-forward in the field of
‘Modern Biotechnology’
rests predominantly
upon reasonably sound
microbiological foundation.
Besides, microorganisms do modulate a plethora
of vital and critical functionalities, such as : (
a
) enable completion of cycles of C, O, N and S which
essentially occur in both
terrestrial and aquatic systems ;
(
b
) provide absolutely indispensable
components of prevailing
ecosystem ;
and (
c
) serve as a critical source of
‘nutrients’
occurring at the
grass-root of practically a large segment of
ecological food webs and chains.
The entire course-content presented in
‘Pharmaceutical Microbiology’
has been meticulously
and painstakingly developed and expanded as per the
AICTE-Approved Syllabus–2000.
Each chapter
has been duly expatiated in a simple, lucid, and crisp language easily comprehensible by its august
readers. A unique largely acceptable style of presentation has been adopted,
viz.,
brief introduction,
principles, labeled figures, graphics, diagrams of equipments, descriptions, explanations, pharmaceutical
applications, and selected classical examples. Each chapter is duly elaborated with adequate foot-notes,
references, and ‘further reading references’ at the end.
An exhaustive
‘Glossary of Important Microbiological Terminologies’
has been duly annexed
at the end of the textbook. A fairly up to date computer-generated
‘Index’
in the textbook will surely
enlarge the vision of its readers in gaining an easy access of subject enriched well documented text
materials.
Pharmaceutical Microbiology
consists of
Ten Chapters :
(1) Introduction and Scope ;
(2) Structure
and Function : Bacterial Cells ; (3) Characterization, Classification and Taxonomy of
Microbes ; (4) Identification of Microorganisms ; (5) Nutrition, Cultivation and Isolation : Bacteria-
Actinomycetes-Fungi-Viruses ; (6) Microbial Genetics and Variations ; (7) Microbial Control by Physical
and Chemical Methods ; (8) Sterility Testing : Pharmaceutical Products ; (9) Immune Systems ; and
(10) Mi
crobiological (Microbial) Assays : Antibiotics–Vitamins–Amino Acids.
The text material essentially embodies not only an ample emphasis on the vivid coverage of
fundamental principles of microbiology as a scientific discipline but also maintains a manageable length
for the apprehension of brilliant students.

Methods and specifications
Testing of pharmaceutical products is carried out according to a Pharmacopeia of which there are a few types. For example: In America, the United States Pharmacopeia is used; in Japan there is the Japanese Pharmacopeia; in the United Kingdom there is the British Pharmacopoeia and in Europe the European Pharmacopeia. These contain a test method which is to be followed when testing, along with defined specifications for the amount of microorganisms allowed in a given amount of product.

The specifications change depending on the product type and method in which it is introduced to the body. The pharmacopoeia also covers areas like sterility testing, endotoxin testing, the use of biological indicators, microbial limits testing and enumeration, and the testing of pharmaceutical grade water.

Methods and specifications
Testing of pharmaceutical products is carried out according to a Pharmacopeia of which there are a few types. For example: In America, the United States Pharmacopeia is used; in Japan there is the Japanese Pharmacopeia; in the United Kingdom there is the British Pharmacopoeia and in Europe the European Pharmacopeia. These contain a test method which is to be followed when testing, along with defined specifications for the amount of microorganisms allowed in a given amount of product.

The specifications change depending on the product type and method in which it is introduced to the body. The pharmacopoeia also covers areas like sterility testing, endotoxin testing, the use of biological indicators, microbial limits testing and enumeration, and the testing of pharmaceutical grade water.
