The population structure of Staphylococcus aureus carried by healthy humans was determined using a large strain collection of nonclinical origin (n = 829). High-throughput amplified fragment length polymorphism (AFLP) analysis revealed 3 major and 2 minor genetic clusters of S. aureus, which were corroborated by multilocus sequence typing. Major AFLP(More)
We compared multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), and amplified fragment length polymorphism (AFLP) for typing of Staphylococcus aureus and show that the methods yield similar results, although with differences in resolving power and reproducibility. Epidemiological conditions should determine which is the optimal(More)
Comparative genomics were used to assess genetic differences between Staphylococcus aureus strains derived from infected animals versus colonized or infected humans. A total of 77 veterinary isolates were genetically characterized by high-throughput amplified fragment length polymorphism (AFLP). Bacterial genotypes were introduced in a large AFLP database(More)
A newly developed oligonucleotide array suited for multilocus sequence typing (MLST) of Staphylococcus aureus strains was analyzed with two strain collections in a two-center study. MLST allele identification for the first strain collection fully agreed with conventional strain typing. Analysis of strains from the second collection revealed that(More)
Clinical isolates of Staphylococcus aureus (n=276) were collected in 10 different hospitals located in the Southwest (cities of Ibadan and Lagos) and North-Central (city of Jos) parts of Nigeria. Resistance profiling of these strains revealed that the vast majority was still susceptible to methicillin (98.6% MSSA). Pulsed field gel electrophoresis (PFGE)(More)
Sterically stabilized liposomes are able to localize at sites of infection and could serve as carriers of antimicrobial agents. For a rational optimization of liposome localization, the blood clearance kinetics and biodistribution of liposomes differing in poly(ethylene glycol) (PEG) density, particle size, bilayer fluidity or surface charge were studied in(More)
Phenotypically identified methicillin resistant Staphylococcus aureus (MRSA) strains from several hospitals in Romania and Saudi Arabia (n = 103 and 68, respectively) were confirmed to be MRSA by mecA PCR and PBP-2' based latex agglutination. Subsequently, strains were differentiated at the sub-species level using pulsed field gel electrophoresis (PFGE) of(More)
Few data on the molecular characteristics and epidemiology of Staphylococcus aureus from Indonesia are available. The purpose of the present study was to define S. aureus reservoirs in both the Indonesian community and hospital using a collection of 329 nasal carriage isolates obtained during a survey of 3,995 healthy individuals and patients from Java,(More)
OBJECTIVES To determine the prevalence, antimicrobial susceptibility profiles and clonal distribution of either methicillin-resistant Staphylococcus aureus (MRSA) or Panton-Valentine leukocidin (PVL)-positive S. aureus obtained from clinical cultures in Indonesian hospitals. METHODS S. aureus isolates from clinical cultures of patients in four tertiary(More)
BACKGROUND We investigated the impact of staphylococcal carriage among patients on continuous peritoneal dialysis (CPD) in a university hospital. METHODS Patients were screened for Staphylococcus aureus carriage and categorized as persistent, intermittent, or non-S. aureus nasal carriers. Patients were subsequently recultured every 12 weeks for S. aureus(More)
