. A retrospective analysis was performed to measure the incidence of pneumococcal bacteremia and to identify risk factors for penicillin resistance and prognostic factors for outcome in adults. A total of 151 cases of pneumococcal bacteremia were identified from 149 adults during the period 1996–2000. The overall rate of penicillin resistance was 49%, ranging from 54.2% in 1996 to 48.5% in 2000 (...
. Toxoplasma infection during pregnancy is widely treated with oral spiramycin to reduce the risk of congenital toxoplasmosis in the infant. Failures of therapy have been observed, however. In this study, a sensitive high-performance liquid chromatography technique was used to measure concentrations of spiramycin and neospiramycin, one of the major metabolites of spiramycin, in maternal serum and...
. Xylitol prevents otitis media when given to children regularly five times per day. To find a more convenient dosing schedule, an enzymatic assay was used to measure xylitol concentrations in the saliva of 65 children after giving them xylitol chewing gum or syrup in doses equal to those used in clinical trials. Although concentrations high enough to have an antimicrobial effect were attained, the...
Abstract. The bactericidal activities and post-antibiotic effects of BMS-284756 (T-3811ME), levofloxacin, and ciprofloxacin were evaluated against a methicillin-susceptible and a methicillin-resistant Staphylococcus aureus strain. Minimum inhibitory concentrations (MICs), minimum bactericidal concentrations, post-antibiotic effects, and post-antibiotic sub-MIC effects were determined and time-kill...
. A rapid, single-step, in-laboratory qualitative test for the detection of IgG antibodies to Helicobacter pylori in serum (TestPack Plus; Abbott Laboratories, Germany) was evaluated. This test may be used as an alternative to enzyme immunoassays (EIAs). Of 153 adult patients, 110 were defined as Helicobacter pylori positive and 43 as Helicobacter pylori negative by the gold standard, a combination...

. The aim of the study presented here was to describe the different epidemiological methods used to investigate an outbreak of Q fever that occurred in the spring of 1996 among inhabitants of Briançon, a small town in the French Alps. Three approaches were used: (i) a comparison between a 2-month exhaustive serological survey among blood donors and a retrospective serological survey performed on...
. Diagnostic assays allowing the quantification of hepatitis B virus (HBV) DNA over a wide range of concentrations are important for monitoring patients during antiviral therapy. The aim of this study was to develop a new real-time method for HBV DNA quantification. Primers and probe were selected in a highly conserved region of the HBV S gene, and a plasmid containing the pre-S/S region was used...
. The epidemiology and clinical features of 46 cases of human leptospirosis diagnosed in Israel between 1986 and 1999 were analysed. The median patient age was 37.5 years (range, 16–85 years), and the male/female ratio was 43/3. The most common serogroup found was Leptospira icterohaemorrhagiae. The disease was associated with jaundice in 71% of cases, acute renal failure in 62%, rhabdomyolysis in...
. During a 3-year period, three cases of bacterial meningitis developing after spinal or epidural anesthesia were observed at one hospital in Germany. The causative organisms were Streptococcus salivarius (2 cases) and Staphylococcus aureus (1 case). In the first two cases, contamination of the needle by oropharyngeal flora of the anesthesiological team was likely but remained unproven. In the third...

. In the study presented here, peripheral blood specimens obtained from patients with atherosclerosis were examined for the presence of Chlamydia pneumoniae to determine whether these specimens can be used for routine testing. Chlamydia pneumoniae DNA was detected in 7 of 56 patients with carotid stenosis and in three of four patients with other atherosclerotic diseases, but it was not detected in...
