polymerase chain reaction identification of coagulase-negative staphylococci and of strain diversity and spread of staphylococcus epidermidis in a major medical center in lebanon. | a 2-step polymerase chain reaction (pcr) assay and random amplification of polymorphic dna (rapd) analysis, respectively, were assessed to identify coagulase-negative staphylococci organisms to the species level and to determine the strain diversity and spread of staphylococcus epidermidis, the most frequently isolated species, in a medical center in beirut, lebanon. our data indicated that pcr was faster and was more efficient in identifying s. epidermidis isolates than is conventional biochemi ... | 2006 | 16807861 |
