Evaluation of a new bacteriophage set for typing of Staphylococcus epidermidis strains.
نویسندگان
چکیده
A new set of typing phages was evaluated for typing 821 Staphylococcus epidermidis strains isolated from normal human skin and from acne lesions. This method was compared with two different systems for biochemical differentiation of S. epidermidis. Distinct subgroups of cocci, which differed in phage susceptibility as well as in biochemical properties, were found. A tentative subdivision of S. epidermidis strains by use of 16 phages arranged into four groups is proposed, together with additional biochemical differentiation of non-typable strains.

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 کاملDevelopment of a bacteriophage-typing set for Staphylococcus epidermidis.
Six phages isolated from lysogenic cultures of Staphylococcus epidermidis were used to type cultures in our collection classified previously as "untypable" with our original typing set of 13 phages, new clinical isolates from Missouri, and clinical isolates from Connecticut, Georgia, Pennsylvania, and Virginia. Typability with the new set of 6 phages and with our 13 original phages was compared...
متن کاملPhage typing of Staphylococcus epidermidis.
Thirteen phages were isolated from lysogenic cultures of Staphylococcus epidermidis from a clinical laboratory and used to type 223 clinical isolates of this organism. The 18 phages isolated in The Netherlands were used to type these same cultures. No correlation was observed between phage type, biotype, or clinical source of isolation. At phage concentrations of 100 times the routine test dilu...

The sequences of the ccrAB genes from bovine-, canine- and chicken-originating methicillin-resistant Staphylococcus (S.) epidermidis (MRSE) and bovine methicillin-resistant Staphylococcus (S.) aureus (MRSA) were compared to investigate the frequency of intra-species horizontal transfer of the staphylococcal cassette chromosome mec (SCCmec) complex. Nineteen MRSE strains were isolated from bovin...
متن کاملUse of outer surface protein repeat regions for improved genotyping of Staphylococcus epidermidis.
Staphylococcus epidermidis is an important nosocomial pathogen, but little is known of its epidemiology. Accurate, reproducible typing systems would greatly improve epidemiologic investigations of S. epidermidis. The sequence-based typing technique most recently evaluated, multilocus sequence typing (MLST), often lacks discrimination and can be expensive. PCR and sequence-based analyses of the ...
