Salmonella Probably Killed the Aztecs (theguardian.com)
An anonymous reader quotes a report from The Guardian: In 1545 disaster struck Mexico's Aztec nation when people started coming down with high fevers, headaches and bleeding from the eyes, mouth and nose. Death generally followed in three or four days. Within five years as many as 15 million people -- an estimated 80% of the population -- were wiped out in an epidemic the locals named "cocoliztli." The word means pestilence in the Aztec Nahuatl language. Its cause, however, has been questioned for nearly 500 years. On Monday scientists swept aside smallpox, measles, mumps, and influenza as likely suspects, identifying a typhoid-like "enteric fever" for which they found DNA evidence on the teeth of long-dead victims.
Scientists now say they have probably unmasked the culprit. Analysing DNA extracted from 29 skeletons buried in a cocoliztli cemetery, they found traces of the salmonella enterica bacterium, of the Paratyphi C variety. It is known to cause enteric fever, of which typhoid is an example. The Mexican subtype rarely causes human infection today. Many salmonella strains spread via infected food or water, and may have travelled to Mexico with domesticated animals brought by the Spanish, the research team said. The study has been published in the journal Nature Ecology and Evolution.

Everyone knows the story - the US government deliberately caused smallpox epidemics by distributing contaminated blankets. There's one problem: it isn't true. It was neither an act of terrorism nor an attempted genocide because it didn't happen. The entire story is a fraud, perpetrated by a former "ethnic studies" professor named Ward Churchill.
The High Plains Smallpox Epidemic of 1837 was caused by personal contact with infected passengers from the riverboat St. Peter's, owned by a fur trading company. The epidemic on the High Plains centered around Fort Clark which, despite the name, was not a military installation. It was a privately owned fur trading post. The boss of Fort Clark was Francis Chardon, a fur trader. His personal diary survived to this day, one of numerous eyewitness accounts preserved from the time.
Not only were infected blankets not distributed, but correspondence from Joshua Pilcher, the Indian Bureau's sub-agent to the Sioux, Cheyenne, and Ponca at Fort Kiowa, just south of Fort Clark, to Mr. Chardon describes one particular problem interfering with attempts to contain the epidemic that is curiously relevant to today. A smallpox vaccine existed in 1837, but Mr. Pilcher noted "it is a verry delicate experiment among those wild Indians, because death from any other cause, while under the influence of Vaccination would be attributed to that + no other cause[.]"
In 2006, Ward Churchill was found guilty of seven counts of research misconduct by the University of Colorado Ethics Committee. He was fired in 2007. He promptly filed suit, and won a jury trial for wrongful dismissal. The jury followed the instructions to the letter in coming to their conclusion, but recognized Churchill for the lying shitheel he was and awarded him precisely $1.00. (One juror denied any such motivation in a public interview.) A judge vacated the jury verdict on the grounds that the (state) university enjoys quasi-judicial immunity. The Colorado Court of Appeals upheld that decision. The Colorado Supreme Court agreed to hear an appeal and in 2013 agreed with both the first judge and the Court of Appeals that the university was immune to suit in these circumstances. The US Supreme Court declined to get involved.
It took 19 years from when Churchill first published his fraudulent bullshit in 1994 to the time when the judicial system finished with the case. It could easily take four or five generations for his lie to finally exit the public consciousness. This despite the fact that humanity currently has the fastest, most ubiquitous communications systems in the history of the species.
Shutting down free speech with violence isn't fighting fascism. It IS fascism!
It is true that the bacterium discussed in the Nature, Evolution & Ecology paper discusses is of the genus Salmonella, but describing the disease that killed the Aztecs as being "salmonella" conveys the wrong information to the lay reader (or even the scientifically informed one) since this term is commonly used to describe food borne disease. There are several different pathogenic bacteria species, and subspecies, in the genus Salmonella. The infectious form of Salmonella enterica that is transmitted person-to-person is a different sub-species from ones that cause food poisoning and in this form is known as Paratyphoid Fever (similar to the related Typhoid Fever).
