Multiple-locus variable-number tandem repeat fingerprinting as a method for rapid and cost-effective typing of animal-associated Staphylococcus aureus strains from lineages other than sequence type 398.

In veterinary medicine, Staphylococcus aureus is associated with a range of mild to severe infections. The high density of livestock in intensive farming systems increases the risk of disease spread and hampers its control and measures of prevention, making S. aureus one of the most important animal pathogens. Multiple-locus variable-number tandem repeat fingerprinting (MLVF) has been successfully applied to the characterization of livestock-associated meticillin-resistant Staphylococcus aureus (MRSA) ST398 but not to the characterization of a wide range of other animal isolates. The objective of the current study was to examine the effectiveness of MLVF for studying S. aureus strains isolated from households, farms and exotic animals in three regions of Poland. MLVF, random amplification of polymorphic DNA (RAPD), spa typing and diagnostic microarrays were compared to determine the most suitable combination of methods for veterinary purposes. MLVF generated results consistent with host and geographic origins, reflecting population structures with a high concordance to spa typing results. MLVF has been proven to be a rapid, highly discriminatory and cost-effective method suitable for molecular typing in veterinary settings.

The value of nurses' codes: European nurses' views.

Nurses are responsible for the well-being and quality of life of many people, and therefore must meet high standards of technical and ethical competence. The most common form of ethical guidance is a code of ethics/professional practice; however, little research on how codes are viewed or used in practice has been undertaken. This study, carried out in six European countries, explored nurses' opinions of the content and function of codes and their use in nursing practice. A total of 49 focus groups involving 311 nurses were held. Purposive sampling ensured a mix of participants from a range of specialisms. Qualitative analysis enabled emerging themes to be identified on both national and comparative bases. Most participants had a poor understanding of their codes. They were unfamiliar with the content and believed they have little practical value because of extensive barriers to their effective use. In many countries nursing codes appear to be 'paper tigers' with little or no impact; changes are needed in the way they are developed and written, introduced in nurse education, and reinforced/implemented in clinical practice.
