Strains of Staphylococcus (S.) intermedius from dogs, pigeons, horses and mink were typed by comparison of rRNA gene restriction fragment length polymorphisms (ribotyping) and the resulting ribotypes examined by cluster-analysis. Digestion of whole-cell DNA with HindIII resulted in 9 ribotypes with 3 to 4 bands. Separation of isolates from different host(More)
In order to study the possible clonal relation of Staphyloccocus (S.) intermedius from canine superficial pyoderma and from healthy carriers, isolates from pustular swabs and from vaginal, nasal and normal skin sabs were typed using macrorestriction analysis with Sma I and pulsed-field gel electrophoresis. From the size of the resulting fragments the size(More)
—This paper presents two new structures for six-port reflectometers with very large operating bandwidths of more than three decades, using a combination of lumped reflectors and transmission lines. Circuits working over a range of 2 MHz to 1300 MHz and 2 MHz to 2200 MHz have been built using inexpensive passive surface mount elements and Schottky detector(More)
Staphylococcus intermedius cultures from dogs, pigeons, horses and mink were investigated for the prevalence of the insertion elements IS256 and IS257 in relation to their antibiotic resistance. Copies of IS256 could not be detected in any of the Staph. intermedius isolates tested whereas single copies of IS257 occurred in the isolates from dogs and horses.(More)
A continuously variable transmission type W-band phase shifter based on a single pole bandpass filter tuned by MEMS actuated fingers is reported. Tuning is achieved by means of two half-wavelength long conductive fingers that synchronously rotate upwards in an antiparallel fashion. The fingers deflection results in a distributed variable shunt capacitance(More)
