Abstract: Nos últimos anos, o interesse na compreensão do papel dos microrganismos que colonizam superfícies patrimoniais e nas metodologias para a sua caracterização aumentou significativamente. O desenvolvimento de técnicas avançadas de sequenciação de DNA e análises metagenómicas permitiu uma compreensão mais profunda das comunidades microbianas e dos seus impactos. Além disso, técnicas de microscopia e microanálise avançadas têm sido empregadas para visualizar e estudar estas comunidades microbianas em detalhe.&#xD;
Paralelamente, surgem novas soluções biotecnológicas ecológicas para a mitigação dos efeitos nocivos dos microrganismos no património cultural.</summary>

Abstract: The understanding of purple biodeterioration, or the appearance of purple tinged stains in parchment, has seen a sharp evolution in the last few years. Modern molecular analysis of the DNA, using Next-Generation Sequencing, have made it possible to hypothesize a chain of events triggered by the presence of Archaeobacteria in the parchment, a succession theory that builds on the presence of complex biological communities to explain the appearance of such stains. A few of the codices in the Alcobacense collection display such a disease – termed measles – and this paper tells of the results obtained after the analysis performed on one of them, Alcobacense 338.</summary>
