Microbiology and Infectious Diseases Service, Hospital General Universitario Gregorio Marañón, Madrid, Spain.

We examined the in vitro activity of linezolid against Clostridium difficile, including isolates with reduced susceptibility to metronidazole or vancomycin. The MIC at which 50% of the isolates were inhibited (MIC50) and MIC90 were 0.5 and 2 microg/ml, respectively (range, 0.03 to 4 microg/ml). MICs were always <or= 4 microg/ml, and thus, all isolates were considered susceptible.

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
D004761 Enterocolitis, Pseudomembranous An acute inflammation of the INTESTINAL MUCOSA that is characterized by the presence of pseudomembranes or plaques in the SMALL INTESTINE (pseudomembranous enteritis) and the LARGE INTESTINE (pseudomembranous colitis). It is commonly associated with antibiotic therapy and CLOSTRIDIUM DIFFICILE colonization.

D016360 Clostridioides difficile A common inhabitant of the colon flora in human infants and sometimes in adults. The type species Clostridioides difficile is formerly known as Clostridium difficile. It is a causative agent for CLOSTRIDIOIDES INFECTIONS and is associated with PSEUDOMEMBRANOUS ENTEROCOLITIS in patients receiving antibiotic therapy. Clostridium difficile
D020713 Vancomycin Resistance Nonsusceptibility of bacteria to the action of VANCOMYCIN, an inhibitor of cell wall synthesis.
