Abstract

ANTIBACTERIAL POTENTIAL OF GREEN TEA (CAMELLIA SINENSIS) AGAINST URINARY TRACT INFECTION

J. Ananthi* and R. Sagaya Giri

ABSTRACT

Urinary tract infection is the most common disease in females and males, which is a big threat of kidney failure. In the present study Camellia sinensis (Green tea) leaves extracts were tested against various bacteria isolated from urine samples collected from various hospital in Thanjavur. Isolated bacteria were identified by gram staining and biochemical tests. Tea leaves were collected from Ooty. The natural and commercial green tea extracts were prepared by using standardized protocols. The antibacterial activity of two extracts were tested by disc diffusion method. Significant zone of inhibition was reported in all bacterial isolates of UTI infection. All bacterial pathogens isolated from UTI samples showed maximum growth suppression in natural green tea extracts than the commercial green tea extracts. The methanolic extracts of Camellia sinensis showed the antibacterial activity against the bacteria E.coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, and Proteus mirabilis which cause UTI. The highest susceptibility was observed in Proteus mirabilis and Staphylococcus aureus in both natural and commercial green tea extracts.
