Gram Research analysis of archaeological evidence from central Italy reveals that fungal infections were present in people living 1,400 years ago during the transition from Roman to Medieval times, likely due to agricultural changes, reduced dietary diversity, and environmental shifts following the Roman Empire’s collapse. Researchers developed new diagnostic methods to identify these infections in ancient bones, suggesting that fungal diseases were more common in ancient populations than previously documented by archaeologists.
Researchers studying skeletons from central Italy dating back 1,400 years discovered evidence that fungal infections were more common than previously thought during the transition from Roman to Medieval times. By examining bones from the archaeological site of Selvicciola, scientists found signs of fungal diseases in several individuals and developed new methods to identify these infections in ancient remains. The study suggests that major changes in farming practices, diet, and living conditions after the Roman Empire collapsed may have made people more vulnerable to fungal infections, which are often missed by archaeologists studying old bones.
Key Statistics
A 2026 case study published in Scientific Reports identified evidence of mycotic infections in skeletal remains from the Selvicciola archaeological site in central Italy, dating between 426 and 639 CE, using newly developed diagnostic criteria combining bone morphology analysis and 3D imaging technology.
Research from the Selvicciola assemblage demonstrates that the collapse of the Roman Empire and subsequent agricultural intensification in central Italy coincided with increased vulnerability to fungal infections, suggesting that major social and environmental changes significantly impact disease prevalence in ancient populations.
According to research reviewed by Gram, paleopathologists have historically underdiagnosed fungal infections in ancient skeletal remains due to lack of standardized diagnostic criteria, meaning the true prevalence of mycotic diseases in archaeological populations was likely substantially higher than previously documented.
The Quick Take
- What they studied: Whether fungal infections were present in people who lived in central Italy between 1,400 and 1,600 years ago, and why these infections might have been more common during that time period.
- Who participated: Skeletal remains from the Selvicciola archaeological site in Viterbo, Italy, dating from the late 300s to early 800s CE. The study examined multiple individuals from this burial site.
- Key finding: Researchers found evidence of fungal infections in several skeletons and developed a new systematic way to identify these infections in ancient bones using detailed examination of bone damage patterns and 3D imaging technology.
- What it means for you: This research helps us understand how major historical changes, like the fall of the Roman Empire, affected people’s health through changes in food, farming, and living conditions. It also shows that archaeologists may have been underestimating how common fungal diseases were in ancient populations.
The Research Details
Researchers examined skeletal remains from an archaeological site in central Italy that contained burials from approximately 1,600 years ago. They carefully studied the bones for signs of fungal infections, looking at patterns of bone damage, how the bone had responded to infection, and using advanced 3D imaging technology to see details invisible to the naked eye.
The team developed a new structured approach to identify fungal infections in ancient bones. This involved creating clear diagnostic criteria, basically a checklist of features that would indicate a fungal infection rather than other types of bone disease. They combined information about what the lesions (damaged areas) looked like, how the bone had tried to heal itself, and detailed imaging to make accurate diagnoses.
The researchers also considered the historical context: the fall of the Roman Empire, the arrival of the Longobards (a Germanic people), and how these events changed agriculture, diet, and living conditions for people in the region.
Fungal infections in ancient bones are often overlooked or misidentified by archaeologists because there haven’t been clear, standardized ways to recognize them. This study matters because it provides a reliable method for identifying these infections, which means we can now get a more accurate picture of how common fungal diseases actually were in ancient populations. Understanding past disease patterns helps us learn how environmental and social changes affect human health.
This study was published in Scientific Reports, a peer-reviewed scientific journal. The researchers used multiple lines of evidence (bone morphology, internal bone response, and 3D imaging) rather than relying on a single method, which strengthens their conclusions. The study is limited by the fact that it focuses on one archaeological site and doesn’t provide a specific count of how many individuals were affected, but it establishes important new diagnostic criteria that other researchers can use.
What the Results Show
The research team identified evidence of mycotic (fungal) infections in several individuals from the Selvicciola burial site. Using their newly developed diagnostic approach, they were able to recognize bone lesions and patterns of bone response that indicated fungal disease rather than other conditions.
The infected individuals lived between approximately 426 and 639 CE, a period of significant social and environmental change in central Italy. This timing is important because it coincides with the collapse of Roman infrastructure and the arrival of new populations who changed how farming was done in the region.
The study demonstrates that fungal infections were likely more prevalent in ancient populations than previously documented in archaeological literature. This underestimation occurred because paleopathologists (scientists who study disease in ancient remains) lacked consistent criteria for identifying fungal infections.
The research highlights how interconnected factors, agricultural changes, reduced dietary diversity, environmental conditions, and social upheaval, likely combined to increase vulnerability to fungal infections. The shift from Roman agricultural practices to more intensive farming methods may have altered the environment in ways that promoted fungal growth. Additionally, reduced crop diversity meant people had less varied diets, which could have weakened their immune systems and made them more susceptible to infection.
Previous archaeological studies have documented fungal infections in ancient remains, but these cases were often identified inconsistently or missed entirely. This study builds on existing clinical knowledge about fungal diseases and paleopathological literature to create the first structured, systematic approach to diagnosing mycotic infections in skeletal remains. This represents a significant advance in how archaeologists can study ancient disease patterns.
The study focuses on a single archaeological site, so the findings may not represent all populations during this time period. The exact number of affected individuals is not specified in the research summary. Additionally, while the study establishes new diagnostic criteria, it doesn’t provide statistical data about infection prevalence rates. The research is also limited by the nature of archaeological evidence, not all infections leave marks on bones, so the true infection rate in ancient populations was likely higher than what can be detected.
The Bottom Line
This research provides archaeologists and paleopathologists with a new tool for identifying fungal infections in ancient skeletal remains. For the general public, it demonstrates how major historical and environmental changes can significantly impact human health. While this study doesn’t provide direct health recommendations for modern people, it underscores the importance of diverse diets and stable living conditions for maintaining health, lessons that remain relevant today.
Archaeologists, paleopathologists, and historians studying ancient disease patterns should use these new diagnostic criteria. Medical historians interested in how social collapse affects population health will find this research valuable. The general public should care because it illustrates how interconnected factors, food systems, environment, and social stability, influence disease patterns across centuries.
This is historical research, so there is no timeline for personal health benefits. However, the diagnostic methods developed in this study will help archaeologists identify fungal infections in other ancient sites going forward, gradually improving our understanding of disease patterns throughout human history.
Frequently Asked Questions
How did archaeologists identify fungal infections in 1,400-year-old bones?
Researchers examined bone lesions for specific patterns of damage, studied how the bone had responded to infection, and used 3D imaging technology to see microscopic details. They developed a structured checklist of features that distinguish fungal infections from other bone diseases.
Why were fungal infections more common after the Roman Empire fell?
Agricultural changes, reduced crop diversity, and environmental shifts weakened people’s health. Limited diet variety and changing living conditions made populations more vulnerable to fungal infections, which thrive in certain environmental conditions.
Could fungal infections in ancient times be treated?
The study doesn’t address ancient treatments, but it shows fungal infections affected people during this period. Modern antifungal medications didn’t exist then, so infections likely caused significant illness and some deaths.
Are fungal infections still a health problem today?
Yes, fungal infections remain common today, though modern medicine can treat them effectively. Understanding how historical conditions increased infection risk helps us recognize modern risk factors like poor nutrition and unsanitary conditions.
Why didn’t archaeologists notice these fungal infections before?
Fungal infections in bones can look similar to other diseases, and archaeologists lacked consistent diagnostic criteria to identify them. This study created the first standardized method, allowing researchers to recognize infections that were previously missed or misidentified.
