Proteus mirabilis is one of the most important pathogens associated with complicated urinary tract infections (acute pyelonephritis, bladder infections, kidney stones) and bacteremia, affecting patients with anatomical abnormalities, immunodeficiency, and long-term urinary catheterization. For epidemiological purposes, various molecular typing methods, such as pulse-field gel electrophoresis (PFGE) or ribotyping, have been developed for this pathogen. However, these methods are labor intensive and time-consuming. We evaluated the discriminatory power of several PCR-based fingerprinting methods (RAPD, ISSR, ERIC-PCR, BOX-PCR and rep-PCR) for P. mirabilis clinical isolates. Typing patterns and clustering analysis indicated that RAPD, BOX-PCR and ERIC-PCR...

Nosocomial infections constitute an important problem in hospitals, intensive care units (ICU) having the highest incidence of this type of infection. Staphylococci, especially Staphylococcus epidermidis and Staphylococcus aureus, are among the most important microorganisms associated with nosocomial infections. S. epidermidis is a common skin resident, and can be introduced into the clinical environment by patients and hospital staff. The situation in hospitals is aggravated by the emergence of multiresistant strains. We evaluated 98 hospital S. epidermidis isolates collected at neonatal, pediatric and adult ICUs and 20 S. epidermidis control skin resident isolates from healthy volunteers, for resistance to ten antibiotics and chemotherapeutic agents, and...
