The total number of persons infected or colonised with vancomycin-resistant enterococci mandatorily reported to the Swedish Institute for Infectious Disease Control increased dramatically during 2007 and 2008. During a period of twenty months from 1 July 2007 to 28 February 2009, a total of 760 cases were reported compared with 194 cases reported during the(More)
The results of 28 months of surveillance of postoperative wound infection rates in elective abdominal surgery using triple or single dose antimicrobial prophylaxis are reported. No significant differences in infection rates were seen in 217 patients undergoing gastric, biliary and pancreatic surgery who received either triple or single dose cefuroxime.(More)
It was previously found that Arcanobacterium haemolyticum, which can cause tonsillitis with exanthema, is not eradicated from the pharynx by administration of phenoxymethylpenicillin, despite minimum inhibitory concentration values of 0.015-1.0 micrograms/ml. Therefore, recent clinical isolates were studied for penicillin tolerance by using a disk diffusion(More)
We have previously reported that a wild strain of Francisella tularensis is much less efficiently killed by human polymorphonuclear leukocytes than is an attenuated strain. In the present study, the killing of the attenuated strain was found to be strictly oxygen dependent. The wild and the attenuated strains both induced a respiratory burst in the(More)
Drug-resistant coagulase-negative staphylococci (DRCNS) in orthopaedic patients and ward staff were studied. A significant increase in the DRCNS carriage rate was observed among the 16 patients studied after 14 days of hospitalization with levels approaching that of the staff. Patients receiving dicloxacillin prophylaxis (n = 9) were more likely to be(More)
The aim of this study was to evaluate a commercial tube prepared with boric acid, sodium formate and sorbitol (Hemogard Vacutainer tubes, Becton-Dickinson, HG tubes). Fourteen bacterial strains were incubated in urine in HG tubes and conventional tubes. During a 24-h period, most of the microorganisms grew readily in conventional tubes at room temperature,(More)
Two mobile TOUL-400 units (types 1 and 2) that produce an exponential ultra-clean air flow (EUA) via a mobile screen were evaluated (maximum height from floor to centre of screen: type 1, 1.4m; type 2, 1.6m). Bacterial deposition rates were lowered by >60% (P=0.001) over a table area of 1.7 m (length)x1.0m (width) with the TOUL-400 type 1 unit, and the mean(More)
A total of 952 blood and 1543 urine isolates of gram-negative bacilli from hospitalized patients in 1986-1987 were consecutively collected by 10 Swedish laboratories and tested for susceptibility to 8 beta-lactam antibiotics and to gentamicin. The isolates were mostly Escherichia coli (58% and 44%, respectively) and Klebsiella sp. (17% and 18%). Resistance(More)
An open prospective multicenter study was conducted in order to evaluate the Wellcogen Strep B latex agglutination test in the diagnosis of group B streptococcal (GBS) infections in neonates. Twenty-three (5.9%) of 391 urine specimens and 5 (1.2%) of 404 sera assayed were positive. The results of the urine tests corresponded to a sensitivity of 0.78 for(More)
The present investigation was conducted to find out if a relapse of acute purulent otitis media is associated with a decreased sensitivity of nasopharyngeal pathogens to commonly used antimicrobial agents. All but one of 63 children with relapse included in this study yielded one or more of the classical middle ear pathogens (Streptococcus pneumoniae,(More)
