“…Goto et al (23) demonstrated that tea flavonoids given to elderly women on feeding tubes were found to reduce fecal odor and favorably altered the gut bacteria. Similar results were observed with bedridden patients not on feeding tubes in a separate study with green tea (24). These studies have also raised the possibility of using green tea in other settings where gut bacteria are disturbed, such as after taking antibiotics.…”

Tea that contains many antioxidants is a pleasant and safe drink that is enjoyed by people across the globe. Tea leaves are manufactured as black, green, or oolong. Black tea represents approximately 78% of total consumed tea in the world, whereas green tea accounts for approximately 20% of tea consumed. The concept of "use of tea for promotion of human health and prevention and cure of diseases" has become a subject of intense research in the last decade. Diseases for which tea drinkers appear to have lower risk are simple infections, like bacterial and viral, to chronic debilitating diseases, including cancer, coronary heart disease, stroke, and osteoporosis. Initial work on green tea suggested that it possesses human health-promoting effects. In recent years, the research efforts have been expanded to black tea as well. Research conducted in recent years reveals that both black and green tea have very similar beneficial attributes in lowering the risk of many human diseases, including several types of cancer and heart diseases. For cancer prevention, evidence is so overwhelming that the Chemoprevention Branch of the National Cancer Institute has initiated a plan for developing tea compounds as cancer-chemopreventive agents in human trials. Thus, modern medical research is confirming the ancient wisdom that therapy of many diseases may reside in an inexpensive beverage in a "teapot."

Moreover, Goto et al (1999) who evaluated the effects of tea catechins on faecal contents and metabolites of elderly residents in a long-term care facility, demonstrated that consumption of green tea selectively promoted the growth of Bifidobacterium and Lactobacillus in the gut wall. Known that in our study green tea extract could significantly decrease the survival of Staph.…”

The aim of this study was to assess the effect of a commercial green tea extract (TEAVIGO TM ) on the microbial growth of three probiotic strains (Lactobacillus and Bifidobacterium), as well as three pathogenic bacteria. MIC and co-culture studies were performed. The MICs of the green tea extract against Staphylococcus aureus and Streptococcus pyogenes (100 lg ml -1 ) were considerably lower than those against the probiotic strains tested ([800 lg ml -1 ) and Escherichia coli (800 lg ml -1 ). In co-culture studies, a synergistic effect of the probiotic strains and the green tea extract was observed against both Staph. aureus and Strep. pyogenes. Green tea extract in combination with probiotics significantly reduced the viable count of both pathogens at 4 h and by 24 h had completely abolished the recovery of viable Staph. aureus and Strep. pyogenes. These reductions were more significant than the reductions induced by probiotics or green tea extracts used separately. These results demonstrate the potential for combined therapy using the green tea extract plus probiotics on microbial infections caused by Staph. aureus and Strep. pyogenes. As probiotics and the green tea extract are derived from natural products, treatment with these agents may represent important adjuncts to, or alternatives to, conventional antibiotic therapy.

“…In vivo studies regarding the effects of PEs on gut microbes are less common. In humans, Goto et al (1999) found that consumption of green tea selectively promoted the growth of Bifidobacterium and Lactobacillus in the gut walls of elderly residents in a long-term care facility. Hagmüller et al (2006) did not find any significant differences in the shedding of haemolysing E. coli in weanling piglets fed Thymi herba (Thymus vulgaris, rubbed).…”

The present study evaluated the effects of a novel plant extract (PE) product (Grazix TM ) on the performance and gut health of weaned piglets challenged with Escherichia coli. The PE was a standardised mixture of green tea leaves (Camellia sinensis) and pomegranate fruit (Punica granatum) obtained by using the LiveXtract TM process. A total of 144 piglets were weaned at 24 days and allocated to 8 for a 35-day experiment with a 2 × 2 × 2 factorial design comparing different treatments (water without product (CT) or 8 μl/kg per day PE in drinking water (PE)), feeding regimens (ad libitum (AD) or restricted (RE)) and oral E. coli challenges on day 9 (sham (− ) or infected ( + )). There were six pens per group with three piglets per pen. On day 35, 24 of the RE feeding piglets were slaughtered. It was found that PE supplementation increased the average daily gain (ADG) from day 28 to day 35 ( P = 0.03) and increased the gain to feed ratio (G : F) from day 7 to day 14 ( P = 0.02). RE feeding led to lower feed intake in piglets during the 1 st week ( P < 0.01), 2 nd week ( P = 0.06), 3 rd week ( P = 0.05), and throughout the course of the overall study period ( P = 0.05). E. coli challenge decreased the ADG and G : F ratio from day 7 to day 14 ( P = 0.08 and < 0.01, respectively) and increased the faecal score (higher values indicate more severe diarrhoea) on days 14, 21, 28 and 35 ( P < 0.01). PE supplementation decreased the faecal score in the challenged piglets during the 1 st week post-challenge ( P < 0.01). E. coli challenge increased the faecal E. coli level on day 14 ( P = 0.03) and increased the Enterobacteriaceae level on day 35 ( P < 0.01). Reduced faecal E. coli was observed on days 14 and 35 ( P = 0.05 and 0.02, respectively), and reduced Enterobacteriaceae ( P < 0.01) was found on day 35 in the PE animals. RE feeding increased the faecal Lactobacillus, Enterobacteriaceae and E. coli levels on day 35 ( P = 0.02, < 0.01 and < 0.01, respectively). These results suggest that PE supplementation may improve the gut health status of post-weaning piglets and counteract some of the negative effects that occur when piglets are challenged with E. coli.Keywords: Escherichia coli, gut health, performance, piglet, plant extract ImplicationsThis study investigated the effects of a novel plant extract product that was added to the drinking water for weaned piglets. Different feeding regimens were tested, and the effects of the extract on growth performance, gut health and protection against Escherichia coli challenge were observed. The results showed that the plant extract may represent a useful additive for improving gut health and microbial ecology and reducing the severity of an E. coli challenge. The results may have a significant impact on nutritional management in conventional farms. Use of the plant extract could enable piglets to better withstand the infections that are often associated with weaning.
