The past 2 decades have brought worrying increases in severe Streptococcus pyogenes diseases globally. To investigate and compare the epidemiological patterns of these diseases within Europe, data were collected through a European Union FP-5-funded program (Strep-EURO). Prospective population-based surveillance of severe S. pyogenes infection diagnosed(More)
The incidence of whooping cough in Romania is substantially underestimated, and, as noted by the health authorities, this is mostly due to the lack of both awareness and biological diagnosis. We conducted a 1-year study in Bucharest in order to assess the circulation of Bordetella pertussis, the main etiological agent of whooping cough. Fifty-one subjects(More)
Macrolides, lincosamides and streptogramines are distinct antibiotic (AB) families, with different chemical structure, but with similar antibacterial spectre and mechanisms. Macrolides are natural products of secondary metabolism of several species of actynomyces; they represent a group of compounds with a lactonic ring of variable dimensions (12-22 atoms(More)
Acute Bacterial Meningitis is a medical emergency, which warrants early diagnosis and aggressive therapy, which in most cases must be initiated as an "empirical" treatment. Such an approach needs permanent epidemiological surveillance due to the major variability of the etiological agents depending upon time, geographical areas and demographic(More)
In 2002, the Romanian National Reference Laboratory was invited to join the Strep-EURO project to study invasive Streptococcus pyogenes infections. During 2003 and 2004, a total of 33 isolates recovered from invasive disease were received from eight Romanian counties. For comparison, 102 isolates from non-invasive disease, as well as a collection of 12 old(More)
The prosthodontic treatment must provide for the edentulous patients bio-functional prosthetic restorations, bio-prophylactic for the surrounding tissues. In this aim, an edentulous patient must be submitted to a methodical clinical examination in order to establish the quality of hard and soft tissues, which will indicate the degree of difficulty of the(More)
In the attempt to enrich the local contemporary laboratory data regarding the group B streptococcus (GBS) colonization, isolates obtained from the vaginal swab cultures were characterized for their serotype distribution and antibiotic susceptibility. The 100 GBS isolates analyzed were collected during a four-month period of year 2009 from women screened in(More)
111 neonates with acute respiratory insufficiency and/or severe pneumopathy (pneumonia, bronchopneumonia) occurring in the first 10 hours after birth were investigated during January 1990-September 1991 for the group B streptococci presence. 430 samples from these neonate cases: throat and nose exudates, necroptic material from died neonates (pulmonary,(More)
