Escherichia coli O157:H7 can live undetected in the gut of food animals and be spread to humans directly and indirectly. Bacteriophages are viruses that prey on bacteria, offering a natural, nonantibiotic method to reduce pathogens from the food supply. Here we show that a cocktail of phages isolated from commercial cattle feces reduced E. coli O157:H7 populations in the gut of experimentally i...
BACKGROUND Certain bone marrow-derived cell populations, called endothelial progenitor cells, have been reported to possess angiogenic activity. Experimental data suggest that depletion of these angiogenic cell populations may promote atherogenesis, but limited data are available on their relation to subclinical atherosclerotic cardiovascular disease in humans. METHODS AND RESULTS We studied ...
We have identified a molecule expressed by human marrow granulocyte/monocyte colony-forming cells (CFU-GM), erythroid colony-forming cells (CFU-E), and erythroid burst-forming units (BFU-E), but not their precursors detectable in long-term bone marrow culture. This antigen, detected by flow microfluorimetry using monoclonal antibody 7B9, is coexpressed with CD33 on many CD34+ CFCs, although onl...
background and aims. basic periodontal treatment aims at eliminating supra- and sub-gingival plaque and establishing conditions which will allow effective self-performed plaque control. this aim is primarily achieved with sonic and ultrasonic scalers. however, generation of bacterial aerosols during these procedures is of great concern to patients, the dentist and the dental assistant. the aim ...
An inexpensive, rapid, and simple colorimetric test for detection of bacteriuria is described. This test does not require bacterial growth and has the marked advantage of being able to quantify bacteria, even when the organisms are present in the urine of bacteriuric patients who are being treated with antibiotics. The test is carried out with 1 ml of urine, which is processed through a 10-mm-d...
