Direct latex agglutination testing of selective broth medium for the detection of group B streptococci was evaluated. Results were compared with those obtained by the recommended subculture method. Among the 551 vaginal-rectal specimens tested, 101 (18.3%) were positive by the subculture method. Of these subcultures, latex agglutination testing detected 99 (98%) positive specimens. Agglutination testing...
Between January 1997 and April 2002, 73 consecutive invasive strains of Streptococcus pneumoniae were isolated from children under 16 years of age in four hospitals in suburban Paris. Their genetic diversity was investigated by serotyping and analysis of pulsed-field gel electrophoresis restriction patterns. Antibiotic susceptibility patterns were analysed by disk susceptibility testing and determination...
During the past 8 years, changes in the prevalence and spread of different epidemic methicillin-resistant Staphylococcus aureus (MRSA) have been observed in central Europe, with the emergence of new strains possessing fewer resistance characters. This has also been demonstrated at the level of particular hospitals. Since variation in agr specificity type has been proposed as a possible reason for...
This report describes the case of a 59-year-old woman with a history of non-Hodgkin’s lymphoma who developed bacteremia with Vibrio vulnificus. The patient had been swimming in the unusually warm Baltic Sea in the summer of 2002. She presented with symptoms of septicemia and severe bullous necrotizing skin lesions of the extremities. Blood culture revealed Vibrio vulnificus as the pathogenic organism...
Presented here are two cases of systemic Candida glabrata infection diagnosed in two expectant mothers and their fetuses at 34 and 22 weeks gestation. The underlying risk factors in case 1 were in vitro fertilization and embryo transfer, recurrent yeast vaginitis and two intravenous injections of betamethasone. The risk factors in case 2 were in vitro fertilization and embryo transfer, recurrent yeast...
The aim of the present study was to analyse the clinical and epidemiological characteristics of bronchiolitis caused by respiratory syncytial virus (RSV) in 225 children observed in a paediatric hospital in Lisbon, Portugal, and to determine the clinical, epidemiological, or laboratory parameters that correlate with greater severity of the disease. This prospective study included hospitalised and...
Reported here is an exceptional case of acute retroviral syndrome resembling septic shock that occurred in a chronic HIV-infected patient shortly following planned interruption of antiretroviral treatment. The therapeutic strategy, which is aimed at improving the immunological control of HIV infection, can therefore be deleterious in chronically infected patients and should be avoided outside of closely...
Presented here is a case of monobacterial peritonitis complicating cholecystitis and caused by an uncommon agent of gastrointestinal infections, Haemophilus parainfluenzae. The pathogenic role of this organism in digestive infections, particularly in those of the biliary tract, has been reported increasingly though sporadically. Indeed, it has been shown to be a coloniser of the gastrointestinal tract,...
The ability of extended-spectrum -lactamase (ESBL)-producing and non-ESBL-producing Klebsiella pneumoniae strains to induce a respiratory burst in polymorphonuclear leukocytes (PMNLs) was investigated. Ninety ESBL-producing and 178 non-ESBL-producing Klebsiella pneumoniae isolates were serotyped and their ability to induce a respiratory burst in PMNLs tested by monitoring the cells chemiluminescence...

Among avian influenza viruses and avian paramyxoviruses are the aetiological agents of two of the most devastating diseases of the animal kingdom: (i) the highly pathogenic form of avian influenza, caused by some viruses of the H5 and H7 subtypes, and (ii) Newcastle disease, caused by virulent strains of APMV type 1. Mortality rates due to these agents can exceed 50% in naïve bird populations, and,...
The ability of extended-spectrum β-lactamase (ESBL)-producing and non-ESBL-producing Klebsiella pneumoniae strains to induce a respiratory burst in polymorphonuclear leukocytes (PMNLs) was investigated. Ninety ESBL-producing and 178 non-ESBL-producing Klebsiella pneumoniae isolates were serotyped and their ability to induce a respiratory burst in PMNLs tested by monitoring the cells’ chemiluminescence...
Sixty-six consecutive patients with brain abscesses referred to a department of neurosurgery during a 10-year period and treated with cefotaxime were studied retrospectively by means of a prospectively designed protocol whose main areas of emphasis were duration of antibiotic treatment, sterilization rate, clinical outcome in relation to prognostic factors, and side effects. Sixty-two of these patients...

Toxoplasmosis is a frequent cause of retinochoroiditis. Although the diagnosis relies mainly on ophthalmological examination, biological approaches are particularly useful in patients with atypical lesions. In a prospective study to determine the value of immunoblotting and immune load calculation in the diagnosis of active toxoplasmic retinochoroiditis, aqueous humor samples from 21 patients with...
Two out of five members of one household presented with clinical signs of trichinellosis after their return to the Netherlands. The family had consumed Trichinella-infected pork in Montenegro, formerly Yugoslavia. Serological tests were performed at 1, 2, 6, and 18months after ingestion of the infected meat. Trichinella-specific IgM, IgG, and IgA antibodies measured in sera from symptomatic and asymptomatic...
