Antibiotic sensitivity test procedure

Antibiotic sensitivity test

Antibiotics are natural or semi-synthetic agents which kill bacteria and other microbes at small doses. The number of antibiotics used in present health care system are many yet not all of them are suitable for every kind of infection. For example rifampicin is best for treatment of tuberculous infection while penicillin is best for syphilis. But these two antibiotics are completely ineffective in vice verse manner. This knowledge of selectivity of an antibiotic […]

What is Electrophoresis | 3 Major Types & Principle in detail

What is Electrophoresis

Electrophoresis is one of the widely used techniques in molecular biochemistry, microbiology, biomedical research. It is a type of protein separation method which relies on protein sizes to segregate the mixture. It is one of the highly effective techniques of analysis and sole method for separation of proteins for western blot, RNA studies, etc. But, […]

Microbial Production of Antibiotics by fermentation & synthesis

Production of antibiotics is very critical to meet the market demands of health care system. Antibiotics are secretions from a certain strain of bacteria to restrict the growth of other bacteria around them. So by natural process, their formation is quite small to meet large demands of humans patients worldwide. In the initial phases of discovery, the production […]

Antibiotics Classification | Their Definition, function & mechanism

antibiotics mechanism of action

Antibiotics are the some of the most valuable and indispensable drug molecules in the present world. Many people survive from deadly bacterial infections and communicable diseases like tetanus, septicemia, typhoid, tuberculosis,  etc. due to these antibiotics. Use of antibiotics greatly decreases untimely mortality of many infected patient. There are many types and are selected based on the prior experience or by antibiotic sensitivity test for […]

Recombinant DNA technology (rDNA) and its applications

Recombination DNA technology or rdna technology is a sophisticated molecular biology developed to produce essential biologicals on wide scale to match the demands of the huge population. Rdna technology applications in health care are mind blowing, for instance the insulin required as supplement for diabetic patients was procured previously from cattle and pigs. But the quantity of supply was very small, yet expensive and also not […]

11 Organ Systems | Their Important Functions in the Human Body

Human body has many organs which play an important role in body physiology. These organs are differentiated into organ systems for ease of study. The concept of an organ comes from the fact that a group of tissues are involved in a common function by forming an anatomical structure. This anatomical structure is called an […]

Particle Definition & Importance of Particle Size

Particle Definition

A particle is a fine solid material which is formed either due to condensation of fine solid mass or breakage of large solid mass into smaller single entities. Particle Definition: “Particles are the small and discrete fragments of matter which tend to flow and spread.” They have a set of properties which define the nature of the […]

Insecticides and Pesticides | Their Types Uses & Effects

Insecticides and Pesticides

Insecticides and Pesticides are some of the most toxic chemicals used in present world regularly. Insecticides are agents used to kill or repel the insects present in a vicinity. The insects commonly aimed are mosquitoes, flies, cockroaches, bugs, etc. These insecticides are used regularly in indoors like in homes, hotels, theaters, restaurants, recreation clubs and also to a great extent in outdoors like agriculture farms […]

Atomic Absorption Spectroscopy | Instrumentation & applications

atomic absorption spectroscopy

Atomic absorption spectroscopy (AAS) is another interesting type of spectroscopy. It is specifically designed for the analysis of the metals and metalloids substances. By definition, AAS is a quantitative analytical technique wherein the absorption of a specific wavelength of radiation by the neutral atoms in the ground state is measured. The more the number of […]
