Studies on Nigella sativa black cumin seeds show promising results that it could provide a suitable alternative to antibiotics as growth promoter and safeguard various health issues of animals and humans. The seeds of black cumin with thymoquinone as its main active constituent are mainly used for medicinal purposes and could be used as food spice and nutritional supplements. These have beneficial antinociceptive, antimicrobial, growth enhancing, antiparasitic, immunomoulatory, hepatoprotective, analgesic, anti-inflammatory, antioxidative and bronchodilating effects. Blood pressure regulating as well as bile flow stimulating effects have also been observed.

Scanning electron micrograph of a human neutrophil ingesting methicillin-resistant Staphylococcus aureus MRSA The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy.

The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics.

Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. Horizontal transfer is more likely to happen in locations of frequent antibiotic use.

Additional mutations, however, may compensate for this fitness cost and can aid the survival of these bacteria. Intrinsic antibacterial resistance may be part of the genetic makeup of bacterial strains. Acquired resistance results from a mutation in the bacterial chromosome or the acquisition of extra-chromosomal DNA.

For example, emergent bacterial strains causing tuberculosis that are resistant to previously effective antibacterial treatments pose many therapeutic Thesis antibacterial activity of medicinal plants.

Every year, nearly half a million new cases of multidrug-resistant tuberculosis MDR-TB are estimated to occur worldwide. Antibiotic misuse Per The ICU Book "The first rule of antibiotics is try not to use them, and the second rule is try not to use too many of them.

Self-prescribing of antibiotics is an example of misuse. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections.

[BINGSNIPMIX-3

Other forms of misuse include failure to take the entire prescribed course of the antibiotic, incorrect dosage and administration, or failure to rest for sufficient recovery. Inappropriate antibiotic treatment, for example, is their prescription to treat viral infections such as the common cold.

One study on respiratory tract infections found "physicians were more likely to prescribe antibiotics to patients who appeared to expect them". Food and Drug Administration have advocated restricting the amount of antibiotic use in food animal production. Two federal bills S.

In the United States, the question of emergence of antibiotic-resistant bacterial strains due to use of antibiotics in livestock was raised by the US Food and Drug Administration FDA in Timeline of antibiotics Before the early 20th century, treatments for infections were based primarily on medicinal folklore.

Mixtures with antimicrobial properties that were used in treatments of infections were described over years ago. Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late s.

He then proposed the idea that it might be possible to create chemicals that would act as a selective drug that would bind to and kill bacteria without harming the human host. After screening hundreds of dyes against various organisms, inhe discovered a medicinally useful drug, the first synthetic antibacterial salvarsan [53] [97] [98] now called arsphenamine.

Paul Ehrlich and Sahachiro Hata The era of antibacterial treatment began with the discoveries of arsenic-derived synthetic antibiotics by Alfred Bertheim and Ehrlich in While their early compounds were too toxic, Ehrlich and Sahachiro Hataa Japanese bacteriologist working with Erlich in the quest for a drug to treat syphilisachieved success with the th compound in their series of experiments.

In Ehrlich and Hata announced their discovery, which they called drug "", at the Congress for Internal Medicine at Wiesbaden. This drug is now known as arsphenamine. InEhrlich received the Nobel Prize in Physiology or Medicine for his contributions to immunology.

Research was stimulated apace by its success. The discovery and development of this sulfonamide drug opened the era of antibacterials.

These observations of antibiosis between microorganisms led to the discovery of natural antibacterials. Louis Pasteur observed, "if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics".

In Vincenzo TiberioItalian physician, published a paper on the antibacterial power of some extracts of mold. In his thesis, Duchesne proposed that bacteria and molds engage in a perpetual battle for survival.THE REPORT includes a comprehensive collation of the official FINDINGS OF FACT and Conclusions of the medico-scientific clinical empirical studies conducted by world-respected U.S.
