The in vitro activity of rifaximin against 84 diarrheagenic Escherichia coli and 11 Shigella sonnei causing traveler's diarrhea was evaluated. The MIC of rifaximin ranged between <0.007 and 32 mg/L; other agents tested had an MIC of >256 mg/L in most cases. The results showed the potential use of rifaximin to treat these infections.

D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas

D000078262 Rifaximin A synthetic rifamycin derivative and anti-bacterial agent that is used for the treatment of GASTROENTERITIS caused by ESCHERICHIA COLI INFECTIONS. It may also be used in the treatment of HEPATIC ENCEPHALOPATHY. 4-Deoxy-4'-methylpyrido(1',2'-1,2)imidazo(5,4C)rifamycin,L 105,L-105,Redactiv,Xifaxan,L105

D054307 Enterotoxigenic Escherichia coli Strains of ESCHERICHIA COLI that produce or contain at least one member of either heat-labile or heat-stable ENTEROTOXINS. The organisms colonize the mucosal surface of the small intestine and elaborate their enterotoxins causing DIARRHEA. They are mainly associated with tropical and developing countries and affect susceptible travelers to those places.

D024881 Drug Resistance, Bacterial The ability of bacteria to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS). Antibiotic Resistance, Bacterial,Antibacterial Drug Resistance
