Efficacy of phage typing epidemiologically related Staphylococcus epidermidis strains.
A total of 118 epidemiologically related Staphylococcus epidermidis strains from hospital patients, staff, and fomites were examined with a provisional set of 18 typing phages. Seventy (59.3%) of these strains were typed using phage concentrations of 100 times routine test dilution. The remainder were nontypable. Thirty-six (30.5%) of the strains were of related phage types, 71/108/275A/459 and...
متن کاملWhole Genome Analysis of Epidemiologically Closely Related Staphylococcus aureus Isolates
The change of the bacteria from colonizers to pathogens is accompanied by a drastic change in expression profiles. These changes may be due to environmental signals or to mutational changes. We therefore compared the whole genome sequences of four sets of S. aureus isolates. Three sets were from the same patients. The isolates of each pair (S1800/S1805, S2396/S2395, S2398/S2397, an isolate from...
متن کاملMolecular typing of environmental and patient isolates of Aspergillus fumigatus from various hospital settings.
Fingerprinting of more than 700 clinical and environmental isolates of Aspergillus fumigatus from four differential hospital settings was undertaken with a dispersed repeated DNA sequence. The analysis of the environmental isolates showed that the airborne A. fumigatus population is extremely diverse, with 85% of the strains being represented as a single genotype isolated once. The remaining 15...
متن کامل"Pseudoclusters" and typing by random amplification of polymorphic DNA of Aspergillus fumigatus.
This short report serves as a warning to the unwary of possible "pseudoclusters" of infection with Aspergillus fumigatus as shown by the typing system, random amplification of polymorphic DNA (RAPD). This was demonstrated by typing 10 epidemiologically distinct isolates of A fumigatus using two different preparations of Taq DNA polymerase. One of the enzymes did not discriminate between the iso...
متن کاملTyping of Aspergillus species and Aspergillus fumigatus isolates by interrepeat polymerase chain reaction.
Polymerase chain reaction amplification of repetitive DNA motifs allows discrimination of Aspergillus species. In a preliminary survey, the DNA fingerprints appear to be identical when isolates of Aspergillus fumigatus are compared. When a primer deduced from a prokaryotic repeat motif is used, Aspergillus fumigatus isolates originating from different patients or different anatomical locations ...
