Pathogenic fungi: an unacknowledged risk at coastal resorts? New insights on microbiological sand quality in Portugal.

Whilst the potential impact on beach users from microorganisms in water has received considerable attention, there has been relatively little investigation into microbial contaminants in sand. Thirty three beaches across Portugal were analyzed during a five year period (2006-2010) to determine the presence of yeasts, pathogenic fungi, dermatophytes, total coliforms, Escherichia coli and intestinal enterococci in sand. Our results showed that 60.

Validation of host-specific Bacteriodales 16S rRNA genes as markers to determine the origin of faecal pollution in Atlantic Rim countries of the European Union.

The recent implementation of the Revised Bathing Water Directive in the European Union has highlighted the need for development of effective methods to differentiate between sources of faecal contamination. It had previously been shown that amplification of 16S rRNA genes of host-specific Bacteriodales species using the HF183F and CF128F primers could be used as markers for human and bovine faecal contamination in the United States. This paper determined the sensitivity and specificity of these markers in four Atlantic Rim countries (France, Ireland, Portugal and the United Kingdom) to evaluate their usefulness in determining the origin of faecal contamination.
