Recently the isolation of methicillin-resistant Staphylococcus aureus (MRSA) strains from several food-producing animals has been reported. During slaughtering of MRSA-positive animals, contamination of carcasses with MRSA may occur and consequently the meat of these animals may get contaminated. The aim of this study was to estimate the prevalence of MRSA(More)
Since the first report on methicillin resistant Staphylococcus aureus (MRSA) CC398 in pigs, several countries have determined the prevalence of MRSA-positive pig herds using different sampling and laboratory techniques. The objective of the study was to compare three sampling methods for MRSA-classification of herds. Therefore, nasal swabs of pigs and(More)
A young child was admitted to hospital with haemolytic-uraemic syndrome caused by infection with a Shiga toxin 2-producing strain of Escherichia coli (STEC) O157. Five days before he became ill, the child had visited a small petting zoo. STEC O157 strains were isolated from faecal samples from goats and sheep housed on the farm. The human and the animal(More)
The antibiotic oxytetracycline (oxyTC) was administered either by mixing with food or by intraperitoneal injections. On oxyTC treated animals decreased serum immunoglobulin levels were found. The primary anti-sheep red blood cells (SRBC) response was measured by enumerating plaque forming cells (PFC). It was observed that the PFC response was depressed by(More)
Some mariginal notes regarding possible forms of treatment are made with reference to acute urethral obstruction appearing in a male dog. Although this obstruction was due to a rare cause, the procedure adopted may serve as guidance in planning a scheme of treatment in common cases of urethral obstruction caused by urinary calculi in male dogs.
The influence of thymectomy and splenectomy on the frequency and class distribution of homogeneous immunoglobulins (H-Ig) in serum was studied in lethally irradiated (DBA/2 x C57Bl/Rij)F1 mice reconstituted with syngeneic bone marrow. During four follow-up periods in the first 9 months after transplantation, the sham-operated controls and splenectomized(More)
The cystourethroscopic examination with cold light cystoscopes forms an essential part of a complete urological examination and is useful for diagnostic as well as surgical procedures. The fast and non-invasive character of the procedure limits the inconvenience to the patient. With the rigid non-flexible scope its use is, however, limited to female dogs,(More)
In the Rhine-Delta, accumulation of microcontaminants in floodplain foodwebs has received little attention in comparison with aquatic communities. Here, soil and cattle milk samples were taken from three floodplains and analyzed for polychlorinated biphenyls (PCBs), dibenzodioxins (PCDDs) and dibenzofurans (PCDFs). Based on 2,3,7, 8-tetrachlorodibenzodioxin(More)
