| ["in vitro" activity of ten antimicrobial agents against anaerobic bacteria. a collaborative study, 1999-2002]. | the antimicrobial activity of ampicillin, ampicillin-sulbactam, cefoxitin, ceftriaxone, imipenem, piperacillin, piperacillin-tazobactam, clindamycin, metronidazole, and azitromycin was assesed against 166 strains of anaerobic bacteria recovered from eight hospitals in buenos aires. the strains studied were bacteroides fragilis group (65), fusobacterium spp. (26), prevotella spp. (21), porphyromonas spp. (10), clostridium difficile (10), other clostridia (12), and gram-positive cocci (22). the mi ... | 2004 | 15559195 |
| application of multiple-locus variable-number tandem-repeat analysis to determine clonal spread of toxin a-negative clostridium difficile in a general hospital in buenos aires, argentina. | isolates from patients with clostridium difficile infection (cdi) usually produce both toxin a (tcda) and toxin b (tcdb), but an increasing number of reports from europe and asia mention infections with tcda-negative, tcdb-positive (a-/b+) strains, usually characterized as pcr ribotype 017 (type 017). incidence rates of cdi per 10 000 admissions in a 200-bed argentinean general hospital were 37, 84, 67, 43, 48 and 42 for the years 2000 to 2005, respectively. the annual percentages of type 017 cd ... | 2009 | 19438624 |
| [clostridium difficile diarrhea: frequency of detection in a medical center in buenos aires, argentina]. | clostridium difficile has been recognized as the most important enteric pathogen of nosocomial antibiotic-associated diarrhea (cdad) in adults from industrialized countries. the importance of c. difficile as a cause of diarrhea in ambulatory patients appears underestimated or under-recognized. since the 1980's, outbreaks of cdad have been increasingly reported, but there are few data available in argentina. we developed a retrospective study to provide some information about cdad in our country. ... | 2001 | 11494752 |
