Natural antibacterial clays, when hydrated and applied topically, kill human pathogens including antibiotic resistant strains proliferating worldwide. Only certain clays are bactericidal; those containing soluble reduced metals and expandable clay minerals that absorb cations, providing a capacity for extended metal release and production of toxic hydroxyl radicals. Here we show the critical an...

The possibility that normal tissue constituents may be involved in the mechanism of resistance to infection with Bacillus anthracis was first considered in 1890. In that year Hankin reported the isolation of germicidal extracts from the spleen and lymphatic glands of cats. In 1893 Vaughn reported the preparation of germicidal extracts from spleen, brain, thyroid, and testicular tissue. His proc...

Widespread antibiotic resistance among bacterial pathogens is providing the impetus to explore novel sources of antimicrobial agents. Recently, the potent antibacterial activity of certain clay minerals has stimulated scientific interest in these materials. One such example is Kisameet glacial clay (KC), an antibacterial clay from a deposit on the central coast of British Columbia, Canada. Howe...

Abstract Background Bioactive components isolated from composted agricultural biomasses have been receiving progressive attention, because they may improve the antibiotic susceptibility of drug resistant bacterial strains. Here, three different humic substances (HS) were artichoke (HS-CYN) and pepper (HS-PEP) wastes, coffee grounds (HS-COF), characterized by infrared spectrometry, NMR spectrosc...

Salmonella typhi is a gram-negative rod-shaped bacterium, which can cause typhoid fever. Keji Beling (Strobilanthes crispus) medicinal plant that contains metabolic substances such as flavonoids function antibacterial. The aim of this research was to determine the antibacterial activity starch from leaves against inhibition zone thypi. This study consisted an experimental with completely random...

background & aim: secondary metabolites with bioactive and functional properties in essence of aromatic plants can be useful for improvement of quality and persistence of food as natural preservative.  the aim of this study was to evaluate the in vitro antibacterial of essential oils of some of the medicinal plants collected from chaharmahal va bakhtiari province, iran. experimental: the e...

Sheep’s milk is an important source of bioactive substances that have health-promoting functions for the body. The valuable composition sheep’s due to high content fatty acids, immunoglobulins, proteins, hormones, vitamins and minerals. Many biopeptides found in antibacterial, antiviral anti-inflammatory properties. also show anticancer milk, thanks its CLA orotic acid, prevents occurrence type...

Fatty acids are widely occurring in natural fats and dietary oils and they are known to have antibacterial and antifungal properties. However, little is known on the antibacterial and antifungal properties of the blindyour-eye mangrove (Excoecaria agallocha) and this study for the first time determines the fatty acid composition and the antibacterial and antifungal activities of Fatty Acid Meth...
