Phage typing of Staphylococcus intermedius.
Staphylococcus intermedius, a coagulase-positive staphylococcal species, is a common canine pathogen and a rare human wound pathogen. A total of 145 strains of S. intermedius (ATCC 29663, 4 reference strains, 4 human isolates, 44 canine infection isolates, and 92 isolates from canine gingiva) were screened for lysogenic phage by a modified Fisk method. Nineteen phage preparations were prepared ...
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...
متن کاملTyping of Staphylococcus aureus by pulsed-field gel electrophoresis, zymotyping, capsular typing, and phage typing: resolution of clonal relationships.
Sixty-nine Staphylococcus aureus isolates from two epidemiologically unrelated sources were typed by pulsed-field gel electrophoresis after SmaI digestion of chromosomal DNA (genome typing), and the results were compared with those obtained by other typing methods: phage typing with the international set of phages, capsular serotyping with monoclonal antibodies against capsular polysaccharides ...
متن کاملReaction difference rule for phage typing of Staphylococcus aureus at 100 times the routine test dilution.
Duplicate phage typing tests of 150 isolates of methicillin-sensitive and -resistant Staphylococcus aureus at 100 times the routine test dilution showed that the existing reaction difference rule remains satisfactory when isolates are tested on the same day; i.e., two or more reactions must differ before isolates should be considered distinct. However, if typing is done on different days, a thr...
متن کاملExperiences and observations with the typing of Staphylococcus aureus phage 94.
During a 28-month period, 5,078 cultures from a variety of anatomical sites were received for staphylococcal phage typing. Of these, 503 (10%) were not suitable for the procedure requested. Of the 4,575 viable cultures, 1,030 (23%) of the microorganisms were nontypable at both the routine test dilution (RTD) and at 100 times RTD. Of the 3,545 typable organisms, 3,061 (86%) were lysed at RTD, wh...
