In Pharmaceutical different grades of waters are used and they all must be tested firest before using it for manufacturing any products. Products sometimes get contaminated because of presence of endotoxins so they mus be checked by performing BET test

2. To study importance of different grades of water in veterinary vaccine
manufacturing industry.
To study uses and preparation techniques of different grades of water
used in industry.
To enumerate the number of bacteria present in water samples by
different methods.
3. Water is very widely used in the pharmaceutical, biopharmaceutical and biological industry for
various purpose like as Raw material, Ingredient as a solvent in processing, formulation and
manufacturing of the wide range of the finish products, as API and intermediates and analytical
reagents.
There are many different types of water described in USP monographs that specify uses, acceptable
methods of preparation, and quality attributes. Types of water used in Vaccine Manufacturing industry
are Non-Potable, Potable, Purified and Water for Injection prepared through different techniques such
as distillation, Reverse osmosis, Deionization, Filtration, Softening etc.
Due to its criticality in industry, microbiological control of water is of great importance. Veterinary
vaccines are considered as the sterile parenteral dosage form and water used for the various purpose in
the veterinary vaccine manufacturing facility must have to comply with the regulatory requirements.

11. 3) Bacterial Endotoxin Test
BET tests detect and quantify bacterial Endotoxin which
is extracted from the outer membrane of Gram negative
bacteria.
The critical component of the LAL (Limulus Amebocyte
Lysate) reagents used in Endotoxin tests is derived from
blood cells (amebocytes ) of the horseshoe crab, Limulus
Polyphemus.
It contains the proteins of the blood clotting mechanism,
which is triggered by Endotoxin.
LAL reagents are primarily used to test for Endotoxin in
injectable pharmaceuticals, biological products, and
medical devices.
12. 4) Membrane Filtration Method
The MF Technique was accepted by the U.S. EPA for microbiological
testing of water in the 11th edition of Standard Methods for the
Examination of Water and Wastewater.

13. 5) Pathogen Detection Test
In qualitative estimation the four more commonly found pathogenic bacteria are:
1. Escherichia coli
2. Staphylococcus aureus
3. Pseudomonas aeruginosa
4. Salmonella abony
Initial process:
1. Firstly samples are collected
2. Now aseptically transfer 10 ml of prepare sample into 100ml of Soyabean Casein Digest Media(SCDM).
3. Incubate at 35-37° C for 18-48 hours.
4. Observe after incubation, if growth is present carry out the pathogen testing on selective media.

24. Conclusion
In vaccine manufacturing industry, different grades of water are used for
different purposes. Testing of the Potable water, Purified water and Water for
injection used for the manfuacturing of the veterinary vaccines at the
different stage of the process done for the generation points as well as the user
points to be done using the MPN method, Plate count method and Filtration
method. So as far as the microorganisms are concerned based on the testing
and its respective results reveals that Potable water, Purified water and Water
for injection used for the manfuacturing of the veterinary vaccines comply
with the acceptance limit of the microbiology and states that the control for
the microorganism in water system is there .
