Did you know that kissing in ancient times could have been life-threatening?

The ancient inhabitants of modern Scandinavia struggled not only to survive in the harsh conditions of the Stone Age but also against the invisible killer - bacterial poisoning.

Ancient Scandinavia's Battle Against Bacterial Poisoning

The study, published in Scientific Reports, investigated the presence of pathogens in ancient Scandinavian populations. Led by the Center for Paleogenetics in Stockholm, researchers analyzed DNA extracted from the teeth of 38 Stone Age individuals from Norway and Sweden. Five deadly bacteria, including Yersinia enterocolitica, Salmonella enterica, and Neisseria meningitidis, were identified, highlighting the pervasive nature of bacterial threats. "We know when people began to engage in agriculture in Scandinavia, but we still don't know how it affected overall health," said Helena Malmström from Uppsala University.

Insights into Health and Agriculture

While the onset of agriculture in Scandinavia is known, its impact on the overall health of ancient populations remains uncertain. Helena Malmström from Uppsala University underscores the need to understand how agricultural practices influenced health outcomes. The study found that common bacteria like Yersinia enterocolitica and Salmonella enterica were likely transmitted through undercooked meat or contaminated food, indicating potential health risks associated with early agricultural practices.

Identification of Deadly Pathogens

The research identified pathogens capable of causing severe diseases such as food poisoning, meningococcal disease, and even the plague. Notable findings include the earliest recorded case of plague caused by Yersinia pestis in southern Sweden, and the presence of Clostridium botulinum and Clostridium tetani, which can cause botulism and fatal infections. Nora Bergfeld from Stockholm University highlights the discovery of infected individuals buried at Battle Axe in Linkoping, suggesting the possibility of understanding the cause of their deaths through bacterial analysis.

Implications for Modern Medicine and Societal Health

While these ancient bacterial infections are treatable with modern medicine, they likely posed significant threats to prehistoric populations. Project director Anders Getherstrøm emphasizes the role of interpersonal communication in disease transmission and notes that foodborne infections were particularly impactful in ancient societies. The study prompts reflection on the evolution of disease transmission and underscores the importance of understanding past health challenges in informing modern public health strategies.
