The Recent Emergence of Infection in Romanian Hospitals is Associated with a High Prevalence of Polymerase Chain Reaction Ribotype 027.

Aims: To investigate the epidemiology of infection in Romanian hospitals.

Methods: A survey was conducted at nine hospitals throughout Romania between November 2013 and February 2014.

Results: The survey identified 393 patients with infection.

[Nosocomial Clostridium difficile diarrhea--adverse effect of antibiotic therapy].

C. difficile is recognised as the main cause for colitis in hospitalised patients which are treated with antibiotics, chemotherapics or other drugs that disturb intestinal microbiota. Thus, a rapid and correct diagnostic of Clostridium difficile infections is essential for preventing nosocomial infection spread.

Microbiological and immunological study of staphylococcus vaccine effects in periodontitis.

The aim of this study was to evaluate the immunomodulatory effect of the staphylococcal vaccine inoculated subcutaneously in 15 patients with chronic periodontitis. Bacteriological investigation of samples collected from the periodontal pocket for aerobic and anaerobic microorganisms was performed by classic bacteriological procedures before and after vaccination. The following immune system parameters were evaluated: C reactive protein (CRP), serum level of C3 complement fraction, IgG, IgA, and IgM by immunodiffusion, PMN granulocytes ROS release after in vitro stimulation with opsonized zymosan (OZ) and Concanavalin A (ConA) by chemiluminescence assay and lymphocytes sets and subsets by flow-cytometry immunophenotyping.

Contributions to the taxonomy and biology of Clostridium difficile.

Clostridium difficile was incriminated by Hughes and Jarvis (1987) as a cause of intestinal infections in USA in the 1980-1984 period in 45 p. 100 of cases, whereas Salmonellae only in 12 p. 100.
