To increase our knowledge of the origin and evolution of S. aureus, genetic studies of historical microorganisms may be beneficial. Thus, the aim of this study was to investigate whether osteomyelitic skeletal material (autopsy specimens collected from the mid 19th century until the 1920s) is suitable for detecting historical S. aureus DNA sequences. We established a PCR-based analysis system targeting two specific genes of S. aureus (nuc and fib). We successfully amplified the historical S. aureus nuc and fib sequences for six and seven pre-antibiotic, osteomyelitic bone specimens, respectively. These results encourage further investigations of historical S. aureus genomes that may increase our understanding of pathogen evolution in relation to anthropogenically introduced antibiotics."],["dc.identifier.doi","10.3390/d9040043"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14836"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59047"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1424-2818"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","570"],["dc.title","Staphylococcus aureus Sequences from Osteomyelitic Specimens of a Pathological Bone Collection from Pre-Antibiotic Times"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

An earlier study in this department showed that it was possible to analyze Alu presence/absence in 3000-year-old skeletal human remains from the Bronze Age Lichtenstein cave in Lower Saxony, Germany. We developed duplex Alu screening PCRs with flanking primers for two Alu elements, each combined with a single internal Alu primer. By adding an internal primer, the approximately 400–500 bp presence signals of Alu elements can be detected within a range of less than 200 bp. Thus, our PCR approach is suited for highly fragmented ancient DNA samples, whereas NGS analyses frequently are unable to handle repetitive elements. With this analysis system, we examined remains of 12 individuals from the Lichtenstein cave with different degrees of DNA degradation. The duplex PCRs showed fully informative amplification results for all of the chosen Alu loci in eight of the 12 samples. Our analysis system showed that Alu presence/absence analysis is possible in samples with different degrees of DNA degradation and it reduces the amount of valuable skeletal material needed by a factor of four, as compared with a singleplex approach."],["dc.identifier.doi","10.3390/d9040048"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14840"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59049"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.publisher","MDPI"],["dc.relation.eissn","1424-2818"],["dc.relation.issn","1573-501X"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","570"],["dc.title","Duplex Alu Screening for Degraded DNA of Skeletal Human Remains"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
