Phage 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...

Deoxyribonuclease-positive Staphylococcus epidermidis strains.

Use of the agar plate test for the enzyme deoxyribonucleate 3'-nucleotidohydrolase (deoxyribonuclease) can result in frequent misdiagnosis of Staphylococcus epidermidis as S. aureus.

Pheromone cross-inhibition between Staphylococcus aureus and Staphylococcus epidermidis.

Cross-inhibition by quorum-sensing pheromones between Staphylococcus aureus and Staphylococcus epidermidis was investigated using all known S. aureus agr pheromone subgroups. All S. aureus subgroups were sensitive towards the S. epidermidis pheromone, with the exception of the recently identified subgroup 4. The subgroup 4 pheromone was also the only S. aureus pheromone able to inhibit the S. e...

Susceptibility of Staphylococcus aureus and Staphylococcus epidermidis to 65 antibiotics.

The susceptibilities of 36 recent isolates of Staphylococcus aureus and 35 recent isolates of Staphylococcus epidermidis were determined against each of 65 antimicrobial agents and against two of them in combination. Rifampin was the most active of all the agents tested against both S. aureus and S. epidermidis. Among the penicillins, cloxacillin, dicloxacillin, and nafcillin were most active, ...
