OBJECTIVE Hungary has reported one of the highest incidences of penicillin resistance in Streptococcus pneumoniae in Europe since the 1970s and is still cited accordingly. However, since the end of the 1990s the resistance of pneumococci in Hungary has not been investigated. In this study we assessed the current situation, particularly to establish whether(More)
A 19-year-old man had been admitted to the Hospital because of septic shock and large scale suffusions all over the body. The pathogen had proved to be Neisseria meningitidis serogroup C. In his stabilization period two superinfectious attacks arose. One of them was a bacteremia, caused by a vancomycin-sensitive Enterococcus faecium. The second was a wound(More)
BACKGROUND AND AIMS The 7-valent conjugate pneumococcal vaccine (Prevenar) was introduced as a recommended (but not yet obligatory) vaccine in Hungary in April 2009 and there was a sharp increase in the number of children vaccinated. Hence there is an urgent need for in-depth epidemiological data on invasive pneumococci before vaccination becomes(More)
The relatedness of 112 penicillin-non-susceptible isolates of Streptococcus pneumoniae from Hungary was determined by pulsed-field gel electrophoresis (PFGE), serotyping and antibiotic susceptibility tests. The differences in PFGE patterns closely mirrored the changes in resistance. Some genotypes comprised multiple serotypes, and the genetic diversity(More)
Nosocomial infections are the main cause of extra charges in health care and they relate to patient safety, as well. About 30 percent of healthcare-associated infections can be prevented effectively with infection control and adequate screening methods. Currently, meticillin-resistant Staphylococcus aureus is the main nosocomial pathogen. Protective(More)
Thirty-five clinical isolates of coagulase-negative staphylococci with decreased glycopeptide sensitivity were examined by a penicillin-binding protein (PBP2') latex agglutination (LA) test and were compared to the detection of the mecA gene by PCR, and oxacillin susceptibility determined minimum inhibitory concentrations. The latex test demonstrated high(More)
The authors present a case of a 29-year-old woman who was diagnosed with pneumonia in the left side complicated with pleural effusion and hemorrhagic pericarditis one month after she had undergone tonsillectomy. Eikenella corrodens was identified as pathogenic agent when the empyema was removed during thoracotomy. After the patient was given antibiotic(More)
VIM metallo-beta-lactamase-producing serotype O11 or O12 Pseudomonas aeruginosa isolates infecting or colonizing 19 patients from seven hospitals in Hungary were characterized between October 2003 and November 2005. Macrorestriction analysis revealed the involvement of hospitals from three different towns in northwest Hungary in an outbreak caused by(More)
