ABSTRACT

ABSTRACT

Alcoholic extract of black tea (Camelia sinensis) was assayed for its antibacterial activity against Salmonella serotypes causing enteric fever viz., Salmonella typhi and Salmonella paratyphi A. While all strains of S. paratyphi A tested were found sensitive, only 42.19% of S. typhi strains were inhibited by this extract. Further minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of black tea extract against S. paratyphi A was less compared with that against S. typhi.
