A study on the process of extraction of an antibiotic

Abstract Background Guidelines for antibiotics prior to dental procedures for patients with specific cardiac conditions and prosthetic joints have changed, reducing indications for antibiotic prophylaxis. In addition to guidelines focused on patient comorbidities, systematic reviews specific to dental extractions and implants support preprocedure antibiotics for all patients. However, data on dentist adherence to these recommendations are scarce. Methods This was a cross-sectional study of veterans undergoing tooth extractions, dental implants, and periodontal procedures.

A study on the process of extraction of an antibiotic

Antibiotic is one of the most important commercially exploited secondary metabolites produced by bacteria, fungi and Streptomyces and employed in a wide range. Most of the antibiotics used today are from the microbes.

Bacteria are easy to isolate, culture, maintain and to improve their strain. Bacillus species being the predominant soil bacteria because of their resistant endospore formation and production of vital antibiotic like polymyxin, bacitracin etc.

In the present research study, screening of bacteria, fungi and Streptomyces with potential antibiotic activity was carried out. Among the microbes isolated and identified, Bacillus subtilis, Penicillium chrysogenum and Streptomyces spwere selected on the basis of their anti-bacterial activity.

It was observed that Penicillium chrysogenum metabolites showed maximum antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia with a zone of inhibition of 17mm, 11mm, Bacillus subtilis metabolites showed activity against Staphylococcus aureus and Pseudomonas aeruginosa measured as zone of inhibition of Antibiotics, in one form or another, have been in use for centuries.

Although a wide taxonomic range of microbes have the ability to produce antibiotics. With advances in organic chemistry many antibiotics are now also obtained by chemical synthesis, such as the sulfa drugs. Drugs used in the chemotherapy of infectious diseases are classified into two groups.

Drugs that have been synthesized by chemical procedures in the laboratory are called synthetic drugs while those produced by bacteria and fungi are called antibiotics 2. The antibiotics are widely distributed in the nature, where they play an important role in regulating the microbial population of soil, water, sewage, and compost.

Of the several hundred naturally produced antibiotics that have been purified, only a few have been sufficiently non-toxic to be of use in medical practice. Those that are currently of greatest use have derived from a relatively small group of microorganisms belonging to the genera Penicillium, Streptomyces, Cephalosporium, Micomonospora and Bacillus 3.

Antibiotics are low molecular-weight non-protein molecules produced as secondary metabolites, mainly by microorganisms that live in the soil.

Therefore, many species such as Streptomyces, Bacillus and Penicillium have been studied continuously for their ability to produce antibiotics 4. Currently, the target is to produce antibiotics such as polymyxin and bacitracin from Bacillus 5, 6.

The apparent increase of the occurrence of antibiotic resistance among bacteria during the past years and its possible implication in public health has led to an intensified surveillance of bacterial resistance in many countries.

Treatment of infectious diseases caused by pathogenic bacterial and fungal strains was one of the most traditional problems in the clinical field 9, This necessity encouraged the investigators to synthesize novel and more potent inhibitory compounds like azoles and quinolones derivatives 11, 12 to fight them.

However, the adverse effects and also appearance of bacterial or fungal resistances persuaded the investigators to study on natural products from microorganisms or herbal extracts to discover novel and safe lead compounds 9, It was not until with the discovery of penicillin, the first, best-known and most widely used antibiotic 13, 14 in by an English Bacteriologist, late Sir Alexander Fleming that the first clinical trials of penicillin were tried on humans.

This antibiotic was obtained from a blue green mould of the soil called Penicillium notatum. Penicillin was discovered accidentally in by Fleming, who showed its efficacy in laboratory cultures against many disease producing bacteria.

This discovery marked the beginning of the development of antibacterial compounds produced by living organisms.

Another antibiotic, streptomycin was isolated in by Waksman, a Microbiologist, from a species of soil bacteria, called Streptomyces griseus, particularly tubercle bacilli, and has proved to be very valuable against tuberculosis.

A vigorous search for more antibiotics was on at this time and inanother antibiotic, chloromycetin was discovered by Burkholder 14, It was isolated from S. It has a powerful action on a wide range of infectious bacteria both Gram positive and Gram negative.

Most of the peptide antibiotics produced by Bacillus are active against Gram positive bacteria All isolates were purified three times before freezing and were stored in F-broth medium (Bölske, ) at −80 °rutadeltambor.com DNA extraction, the isolates were grown in 50 ml F-broth in closed tubes at 37 °C for 90 h.
