ANTIBACTERIAL AGENTS

Hi bloggers my topic for this month is antibacterial agents. I would like to discuss in brief regarding the classification mechanism of action of several drugs included in this category. First of all antibacterials are the agents that either kill the bacteria i.e bactericidal or block their replication i.e bacteristatic. CLASSIFICATION BASED ON THEIR MECHANISM OF ACTION:

Antibiotic resistance – super bug

Antibiotics are a particular class of anti-microbials. Anti-microbials is a general term used to cover all class of microbes like bacteria, protozoa, fungi and other such organisms. Antibiotic refers to a drug that is generally used against the infections caused due to bacteria. Starting from the pencilins, cephalosporins and other classes, a number of antibiotics that might be natural, semi-synthetic or synthetic ones are being discovered to fight against different type of infections.

PRINCIPLES OF STERILIZATION

Sterilization is the process of killing all forms of microbial life in or on the given object or preparation. Microbiologically, sterile material is one that contains no living organisms at all and the term sterile is therefore an absolute one. Accordingly, an object is sterile or non sterile but it can never be semisterile or almost sterile. [1]

SECONDARY SCREENING PART I

Hello viewers, After a brief introduction to General Screening Techniques in my previous blog (http://www.pharmainfo.net/dr-girija-sankar/blog/introduction-screening-t...) and Primary Screening (http://www.pharmainfo.net/sirisha/blog/primary-screening) we shall now move onto SECONDARY SCREENING.

Biologics Target bad Bugs

Hello my dear Pharmainfo friends, I take this marked space to present my blog entry over this topic. What are bad bugs and why to target bag bugs? Infectious diseases account for almost 25% of mortality and morbidity and are emerging as the second most common cause of deaths worldwide as reported by World Health Organization survey [1].
