During a 13-month period, 11 equine patients visiting a veterinary teaching hospital for various diagnostic and surgical procedures developed postprocedural infections from which methicillin (oxacillin)-resistant Staphylococcus aureus (MRSA) strains were isolated. The S. aureus isolates were identified by conventional methods that included Gram staining,(More)
Red clover necrotic mosaic virus (RCNMV; genus Dianthovirus) and Turnip rosette virus (TRoV; genus Sobemovirus) are taxonomically and ecologically distinct plant viruses. In addition, the two genera differ in the role of coat protein (CP) in cell-to-cell movement. However, both are small icosahedral viruses requiring CP for systemic movement in the host(More)
The replication complex of Red clover necrotic mosaic virus (RCNMV) has been shown to possess silencing suppression activity. Here a newly developed viral-based assay for the identification of silencing suppression activity was used to provide evidence for a second, mechanistically distinct method of silencing suppression provided for by the RCNMV movement(More)
Four species of the newly proposed genus Macrococcus, namely macrococcus caseolyticus gen. nov., comb. nov. (formerly Staphylococcus caseolyticus Schleifer, Kilpper-Bälz, Fischer, Faller and Endl 1982, 19VP), Macrococcus equipercicus sp. nov., Macrococcus bovicus sp. nov. Macrococcus carouselicus sp. nov., are described on the basis of a phylogenetic(More)
A new subspecies, Staphylococcus hominis subsp. novobiosepticus, isolated from human blood cultures, a wound, a breast abscess and a catheter tip, is described on the basis of a study of 26 strains isolated between 1989 and 1996. DNA-DNA reassociation reactions, conducted under stringent conditions, and macrorestriction pattern analysis demonstrated that(More)
Introduction The incidence of infectious complications in anorexia nervosa is uncertain. It has been suggested that leucopenia in anorexia nervosa contributes to susceptibility to infection or to immunological deficiencies (Hurd, Palumbo and Gharib, 1977). However, the meaning of isolated laboratory investigations with regard to the clinical state of the(More)
A continuous-culture system was developed to study changes in the structure of Staphylococcus epidermidis populations exposed to subminimum inhibitory concentrations of erythromycin. Continuous-culture experiments were carried out in a dextrose-free, tryptic soy broth medium supplemented with lactic acid and sodium lactate (MTSB-D). The multiresistant(More)
Pulsed-field gel electrophoresis was used to examine the chromosomal polymorphisms existing within and between four closely related members of the Staphylococcus epidermidis species group, S. epidermidis, Staphylococcus caprae, Staphylococcus capitis subsp. capitis, and S. capitis subsp. ureolyticus. SmaI was chosen as the restriction endonuclease for this(More)
OBJECTIVES To investigate the degree of polymorphism in the pulsed-field gel electrophoresis (PFGE) patterns of Staphylococcus intermedius and to assess the value of this typing method for discriminating strains. SAMPLE POPULATION 52 S intermedius isolates from diseased and healthy dogs. PROCEDURE Chromosomal DNA of S intermedius was digested with(More)
The accuracies of the MicroScan Pos ID and Rapid Pos ID panel systems (Baxter Diagnostic Inc., MicroScan Division, West Sacramento, Calif.) were compared with each other and with the accuracies of conventional methods for the identification of 25 Staphylococcus species and 4 subspecies. Conventional methods included those used in the original descriptions(More)
