800-year-old graves pinpoint where the Black Death began
The Syriac engraving on the medieval tombstone was tantalizing: “This is the tomb of the believer Sanmaq. [He] died of pestilence.” Sanmaq, who was buried in 1338 near Lake Issyk Kul in what is now northern Kyrgyzstan, was one of many victims of the unnamed plague. By scrutinizing field notes and more photos from the Russian team that had excavated the graves in the 1880s, historian Philip Slavin found that at least 118 people from Sanmaq’s Central Asian trading community died in the epidemic. Slavin was on the trail of the origin of the Black Death, which devastated Europe a decade after the Kyrgyzstan burials...

' Black Plague' Was Killing People at Least 5,000 Years Ago

This 5,000-year-old man had the earliest known strain of plague
(Cell Press) The oldest strain of Yersinia pestis -- the bacteria behind the plague that caused the Black Death, which may have killed as much as half of Europe's population in the 1300s -- has been found in the remains of a 5,000-year-old hunter-gatherer. A genetic analysis publishing June 29 in the journal Cell Reports reveals that this ancient strain was likely less contagious and not as deadly as its medieval version.

First evidence that medieval plague victims were buried individually with 'considerable care'
(University of Cambridge) DNA analysis has revealed the presence of 'Yersinia Pestis' - the pathogen that causes plague - in skeletal remains from individual burials in medieval Cambridgeshire, confirming for the first time that not all plague victims were buried in mass graves. Compassion and care were shown to victims even during traumatic times during past pandemics. (Source: EurekAlert! - Medicine and Health)

Type III secretion system effectors form robust and flexible intracellular virulence networks
Infections with many Gram-negative pathogens, including Escherichia coli, Salmonella, Shigella, and Yersinia, rely on type III secretion system (T3SS) effectors. We hypothesized that while hijacking processes within mammalian cells, the effectors operate as a robust network that can tolerate substantial contractions. This was tested in vivo using the mouse pathogen Citrobacter rodentium (encoding 31 effectors). Sequential gene deletions showed that effector essentiality for infection was context dependent and that the network could tolerate 60% contraction while maintaining pathogenicity. Despite inducing very different co...

What Causes Joint Pain?
DiscussionMusculoskeletal problems are common problems in pediatric practice with up to 15% of acute care visits being for this problem. Joint pain is a common concern for families but the differential diagnosis is extensive and needs thoughtful consideration. History is a key to discerning the potential diagnosis but also in guiding the physical examination and laboratory examination. Family history especially for systemic diseases should be considered. On physical examination all joints should be examined include sacroiliac and temporomandibular joints. Is this arthritis or arthralgia? Distinction between inflammatory...

We Need to Rethink Our Food System to Prevent the Next Pandemic
Once a dangerous new pathogen is out, as we are seeing, it can be difficult if not impossible to prevent it going global. One as contagious as SARS-CoV-2 has the potential to infect the whole of humanity. Eighty per cent of cases may be benign, but with such a large pool of susceptible hosts, the numbers who experience severe illness and die can still be shockingly high. So the only sensible answer to the question, how do we stop this from happening again, is: by doing all we can to prevent such pathogens infecting humans in the first place. And that means taking a long, hard look at our relationship with the natural world...

Plagues and People – The Coronavirus in a Historical Perspective
By Jan LundiusSTOCKHOLM / ROME, Mar 19 2020 (IPS) The human factor is intimately involved in the origin, spread, and mitigation of the Coronavirus and we cannot afford to ignore that our future existence depends on compassion and cooperation. Response matters! Some quarantined Italians might recall Giovanni Boccaccio´s The Decameron from 1353 in which people escaping the plague are secluded in a villa where they tell stories to each other. Boccaccio introduced his collection of short stories with an eyewitness account of horrifying human suffering in Florence, which in 1348 was struck by a ”pestilence” that every day...

How diarrhea pathogens switch into attack mode at body temperature
(Ruhr-University Bochum) Many bacterial pathogens excrete toxins as soon as they have entered the host in order to suppress its immune response. Researchers at Ruhr-Universit ä t Bochum (RUB) have analysed what happens on the molecular level when the diarrhea pathogen Yersinia pseudotuberculosis switches into attack mode. To this end, they examined so-called RNA thermometers, which signal to the bacteria whether they are in the host. (Source: EurekAlert! - Infectious and Emerging Diseases)

Details of first historically recorded plague pandemic revealed by ancient genomes
(Max Planck Institute for the Science of Human History) An international team of researchers has analyzed human remains from 21 archaeological sites to learn more about the impact and evolution of the plague-causing bacterium Yersinia pestis during the first plague pandemic (541-750 AD). The researchers reconstructed 8 plague genomes from Britain, Germany, France and Spain and uncovered a previously unknown level of diversity in Y. pestis strains. Additionally, they found the first direct genetic evidence of the Justinianic Plague in the British Isles. (Source: EurekAlert! - Biology)
