INDEX Bacillus subtilis

Anti-amoebic activity. Ethanol (80%) extract of the dried rhizome was inactive on Entamoeba histolytica, minimum inhibitory concentration (MIC) greater than 1 mg/ mL The extract, administered intragas-trically to male hamsters at a dose of 800 mg/kg, was active vs experimentally induced hepatic amebiasis . A dose of 250 mg/kg, administered intragastrically to rats on days 1-5, produced weak activity and a dose of 500 mg/kg was active " ". Anti-atherosclerotic activity. Ethanol (50%) extract of the dried rhizome, administered intragastrically to male rabbits at a dose of 500 mg/kg, reduced atherogenic index from 4.7 to 1.2 on the aorta . Antibacterial activity. Decoction of the dried entire plant, on agar plate, was inactive on Proteus vulgaris, Staphylococcus aureus, and Staphylococcus epidermidis MIC 125 mg/mL. Bacillus subtilis, Bordetella...

Bacillus subtilis. The B. subtilis genome also attracts considerable attention from biologists and, like that of E. coli, is being actively studied from the functional perspective. The Subtilist Web site, maintained at the Institute Pasteur, is constantly updated to include the most recent results on functions of new B. subtilis genes. In addition, a convenient index of B. subtilis sporulation genes is maintained at the Royal Holloway University of London.
