A sterility test may be defined as a test that critically assesses whether a sterilized pharmaceutical product is free from contaminating microorganisms. According to Indian Pharmacopoea the sterility testings are intended for detecting the presence of viable forms of microorganisms in or on the pharmacopoeal preparations.
In actual practice, one invariably comes across certain absolutely important guidelines and vital precautionary measures that must be adhered to strictly so as to accomplish the utmost accuracy and precision of the entire concept of sterility testing for life-saving secondary pharmaceutical products (drugs). A few such cardinal factors, guidelines, and necessary details are as enumerated under:

Irrespective of the very nature and complexity of an organism, the cell designates the fundamental
structural unit of life. In other words, all living cells are basically similar. The ‘cell theory’ i.e., the concept of the cell as the structural unit of life, was duly put forward by Schleiden and Schwann. In short, all biological systems essentially have the following characteristic features in common, namely :
(1) ability for reproduction,
(2) ability to assimilate or ingest food substances, and subsequently metabolize them for energy and growth,
(3) ability to excrete waste products,
(4) ability to react to unavoidable alterations in their environment — usually known as irritability,
(5) susceptibility to mutation.

Bacterium or bacteria refers to a single-celled organism without having a true nucleus or functionally specific components of metabolism that belongs to the kingdom Prokaryotae (Monera). The internal cytoplasm is invariably surrounded by one-or two-layered rigid cell wall composed of phospholipids.
Some bacteria also produce a specific mucoid extracellular capsule for additional protection, particularly from phagocytosis by white-blood cells (WBCs). Bacteria can synthesize nucleic acids (DNA, RNA), other important proteins and can reproduce independently, but may essentially need a host to supply food and also a supportive environment. In reality, millions of nonpathogenic bacteria live on the skin and mucous membranes of the human gastrointestinal tract (GIT) ; these are termed as normal flora. Importantly, bacteria that cause disease are usually known as pathogens.
