lot more attention is paid to different food extracts such as green tea extracts, grape seed extracts and ginger extracts as they posed excellent antimicrobial, antioxidant and anti-carcinogenic properties (Martin et al. 2009). These extracts have great potential in improving the quality and shelf life of foods by modifying the physiochemical and biological properties of the food (Martin et al. 2009). Polyphenol (or catechins) extracted from green tea extract have shown an excellent antimicrobial effect against Bacillus Subtilis, Escherichia Coli, Proteus Vulgaris, Pseudomonas Fluorescents, Salmonella sp. and Staphylococcus Aureus (Bancirova 2010). Among all the catechins, epigallocatechin-3-gallate (EGCG) and…

It was initially used by locals as a means to treat the symptoms of colds and flu by inhaling the oil extracted from the tree. In clinical trials, It has been demonstrated to possess strong antimicrobial properties capable of eradicating even the MRSA bacterium. In a study conducted by the Department of dermatology in Australia’s Royal Prince Alfred Hospital, a 5% tea tree oil solution was compared with the efficacy of 5% benzoyl peroxide lotion in a trial conducted on 124 participants. It was…

Antimicrobials, also known as antibiotics, have been used as feed supplements to enhance growth and feed efficiency of food animals (1). These antimicrobials are also used to treat, control or even prevent diseases that are caused by microorganisms such as bacteria (2). This is because they belong this a family of drugs that do not cause significant harm to patients, but they are able to kill or inhibit growth of harmful microorganisms (3). It is believed that antimicrobials pose a hazard to…

1. Introduction Antimicrobials have proved to be one of the most successful medicinal discoveries in history, principally because they have turned bacterial infections which were once the leading cause of death, into controllable conditions.[1, 2] These molecules inhibit the reproduction, prevent vital processes occurring, or destroy the bacterial cell wall to aid in fighting infectious diseases.[3, 4] Antimicrobial therapy is one of the foundation stones of modern medicine, and without…

Many products in Ayurveda have antimicrobial activities against many pathogens. Sindur which is a kulpirasayan also is a broad spectrum antibiotic. Antimicrobial activity of tal sindur : Metallic and mineral preparations are unique preparations in Ayurveda. Along with herbal preparations which includes Bhasmas, herbo-mineral preparations, Kupipakwa Rasayanas which are inorganic mineral preparation, are the base of treatment of various diseases in the Ayurveda. Tal Sindoor contains mercury ,…

Jones,R.D et al (2000) gave a review of effectiveness and safety in health care settings. Triclosan is a widely accepted antimicrobial ingredient because of its safety and antimicrobial efficacy. Triclosan is a unique antimicrobial well suited for use in the health care industry in which mildness is a necessity to protect the health care worker during repeated use and antimicrobial activity is a necessity to protect public health. Triclosan has demonstrated immediate, persistent, broad-spectrum…

Recently, the threat of antimicrobial resistance (AMR) has re-emerged on a global scale. Thankfully, it is not the result of a mass pandemic, but the result of the United Nations issuing a statement that “Antimicrobial resistance poses a fundamental threat to human health, development, and security…” The statements underlies what scientists and medical professionals have been saying for years; that AMR is a serious threat facing the entire world. Since humans first used antimicrobials to treat…

Antimicrobial resistance is gaining momentum in health care as a major cause of concern for the implications it bears on treating patients infected with microbial pathogens. Abbreviated as AMR, Antimicrobial resistance, occurs when bacteria that cause illness can no longer be treated with antibiotics (or other prescription drugs) that previously were able to inhibit the growth of or kill off the microbial infection (Frey, 2003, pg 70). For a health care provider this means treating what was once…

essential element for microorganisms and higher organisms because it is involved in many vital cellular reactions at its low endogenous concentrations, acting as a cofactor needed for catalytic and structural activities [36, 37]. Zn ion concentrations of 10-5-10-7 M are required for optimal bacterial growth of most microorganisms in vitro [38]. However, it is claimed that high zinc ion concentrations may have some antibacterial properties [39]. Zn concentration is regulated under physiological…

Antimicrobial peptides (AMPs) are a class of host defence peptides found in all living organisms. They exhibit significant activity against bacteria, virus, fungi and several other pathogens. AMPs share certain common features. (a) They are small molecules with varying amino acid composition and length. (b) They are cationic, due to the presence of positively charged basic amino acids and (c) amphipathic, since they contain alternate hydrophobic nonpolar and hydrophilic, polar residues. AMPs are…
