Vancomycin-resistant enterococci: 15 years and counting
We review the history of vancomycin-resistant enterococci (VRE) and propose a causal model illustrating the roles of exposure to VRE reservoirs, patient characteristics, antimicrobial exposure, and prevalence of VRE in the progression from potential VRE reservoirs to active disease in hospitalized patients. Differences in VRE colonization and VRE infection are discussed with respect to hospital surveillance methodology and implications for interventions. We further document clonal transmission of VRE in a large, urban, teaching hospital and demonstrate VRE susceptibility to a wide array of antimicrobial agents. This model can guide the identification of mutable factors that are focal points for intervention

Ureaplasma urealyticum as a cause of pneumonia in preterm infants: analysis of the white cell response.
The tracheal isolation of Ureaplasma urealyticum from critically ill infants was investigated to determine if the organism was associated with an inflammatory response. Twenty nine neonates consecutively admitted for acute respiratory disease, with birthweights of < 1301 g and no evidence of viral, chlamydial, or bacterial infections, were identified. Culture results for ureaplasmas were correlated with white cell counts and clinical and radiographic features. Sixteen infants had tracheal aspirates and/or blood specimens positive for U urealyticum. Pneumonia was diagnosed more frequently in the U urealyticum positive infants than in the 13 who were negative for the organism. The mean total white cell count, absolute neutrophil, and band form counts were significantly higher in the U urealyticum positive group than in the negative group. These data suggest that U urealyticum can induce an inflammatory response in selected individuals who present with clinical, radiographic, and, in some instances, histological features of pneumonia
