BACKGROUND Pseudomonas aeruginosa is a notorious multidrug resistant nosocomial pathogen. An efflux pump (MexAB-OprM) is the main contributor to the multidrug resistance in clinical isolates of P. aeruginosa. Epigallocatechin-3-gallate (EGCG), a polyphenolic compound extracted from green tea,

The treatment of bone infection requires drug carriers take large number of cargo, be antibacterial, promote proliferation and differentiation of osteoblasts. Herein, we proposed a strategy of preparing pH responsive, antibacterial, multistage structured microspheres encapsulated with green tea

The aim of this study was to investigate the short-term effects of green tea consumption on selected salivary defense proteins, antibacterial capacity and anti-oxidation activity in taekwondo (TKD) athletes, following intensive training. Twenty-two TKD athletes performed a 2-hr TKD training session.

Bacterial resistance to antibiotics is a persistent and intractable problem. The sapogenin isolated from the seeds of Camellia oleifera can inhibit antibiotic-resistant bacteria after structural modification.

This study aims to improve

This study was conducted to investigate the antibacterial and antiadhesive activities of ethanol extracts from five edible plant parts: cinnamon bark ( Cinnamomum zeylanicum ), licorice root ( Glycyrrhiza radix ), nettle leaves ( Urtica dioica ), green tea leaves ( Camellia sinensis ), and

There is growing interest in the antioxidants and antibacterial activity from natural substances. The purpose of the research was to gain and distinguish phenolic substances and organic acids in the Camellia oleifera cake, and to study their antioxidant and antibacterial activities. The

Extracts of Black tea, Japanese green tea, China tea or Coffee inhibited the growth of various bacteria causing diarrhoeal diseases. Tea or coffee also showed bactericidal activity against Vibrio cholerae, Salmonella typhimurium and Salmonella typhi.

Tea (Camellia sinensis) has been known for its modulation of resistance of methicillin-resistant Staphylococcus aureus (MRSA) to beta-lactam antibiotics in vitro. This study aimed to confirm the in vitro effect of green tea extracts with beta-lactams and to determine whether green tea extracts can

Chitosan is a potential renewable, versatile amino polysaccharide which has been approved by food and drug administration for use in food, cosmetics, pharmaceuticals and other industries. In order to determine if chitosan can be utilized in the development of colourful and multifunctional wool

BACKGROUND In endodontics, most of the commercial intra-canal medicaments have cytotoxic reactions and because of their inability to eliminate bacteria from dentinal tubules, recent medicine has turned its attention to the usage of biologic medication prepared from natural plants. The literature to

The antibacterial activities of 18 naturally occurring compounds (including essential oils and some of their isolated constituents, apple and green tea polyphenols, and other plant extracts) against three strains of Mycobacterium avium subsp. paratuberculosis (a bovine isolate [NCTC 8578], a

An antibacterial compound active against Streptococcus mutans was isolated from Kaempferia pandurata and identified as isopanduratin A using 1H NMR, 13C NMR and EI-MS. The minimum inhibitory concentration (MIC) of isopanduratin A was 4 mg/l which was much lower than that of some other natural

Natural biologically active substances have received continuous attention for the potentially beneficial health properties against chronic diseases. In this study, bacteriostatic active substance from Camellia oleifera meal, which is a major by-product of the Camellia oil processing

Hydroxyapatite-based implant is widely used in the fields of artificial teeth and bones. However, the problem of microbial communities on hydroxyapatite surfaces remain a great challenge. In order to inhibit bacterial adhesion and activity in a long term, a salivary acquired pellicle (SAP)

In this research we evaluated the antibacterial activity of water soluble green tea extracts on isolates of Acinetobacter. A total of 20 strains were collected from burn wounds at different hospitals in Tehran, Iran. The susceptibilities of isolates to different antibiotics were tested using agar
