Abstract
Objective
To investigate how lifestyle may have impacted the risk of contracting intestinal parasites in medieval England . Regular clergy (such as those living in monasteries) and the lay population form interesting groups for comparison as diet and lifestyle varied significantly. Monasteries were built with latrine blocks and hand washing facilities, unlike houses of the poor.
Materials
Sediment samples from the pelvis, along with control samples from feet and skull, of 19 burials of Augustinian Friars (13th-16th century), and 25 burials from All Saints by the Castle parish cemetery (10th-14th century), Cambridge.
Methods
We analysed the sediment using micro-sieving and digital light microscopy to identify the eggs of intestinal parasites.
Results
Parasite prevalence (roundworm and whipworm) in the Augustinian friars was 58%, and in the All Saints by the Castle parishioners just 32% (Barnards Test score statistic 1.7176, p-value 0.092).
Conclusions
It is interesting that the friars had nearly double the infection rate of parasites spread by poor hygiene, compared with the general population. We consider options that might explain this difference, and discuss descriptions and treatment of intestinal worms in medical texts circulating in Cambridge during the medieval period.
Significance
This is the first study to compare prevalence of parasite infection between groups with different socioeconomic status from the same location.
Limitations
Quality of egg preservation was suboptimal, so our data may under-represent the true prevalence.
Suggestions for further research
Larger studies with greater statistical power, covering different time periods and regions.
期刊介绍：
Paleopathology is the study and application of methods and techniques for investigating diseases and related conditions from skeletal and soft tissue remains. The International Journal of Paleopathology (IJPP) will publish original and significant articles on human and animal (including hominids) disease, based upon the study of physical remains, including osseous, dental, and preserved soft tissues at a range of methodological levels, from direct observation to molecular, chemical, histological and radiographic analysis. Discussion of ways in which these methods can be applied to the reconstruction of health, disease and life histories in the past is central to the discipline, so the journal would also encourage papers covering interpretive and theoretical issues, and those that place the study of disease at the centre of a bioarchaeological or biocultural approach. Papers dealing with historical evidence relating to disease in the past (rather than history of medicine) will also be published. The journal will also accept significant studies that applied previously developed techniques to new materials, setting the research in the context of current debates on past human and animal health.
