As far as I know, Bidens has never been tested against the pesticides Yersinia, but it is a natural antibacterial agent, so powerful and systemic that it affects both resistant organisms and organisms that are structurally and functionally similar to Y. Bubonic plague is a disease caused by the Yersian plague, a gram-negative, immobile, sticky bacteria of the genus Coccobacillus, most often transmitted to humans through the bite of Oriental mouse flea Xenopsylla cheopis. U.S. and Russian troops have developed viable methods of airborne distribution of Yersinia pesticides without the need for an intermediate host, and we can assume that these organisms are the most resistant. Resistance to eight different antibiotics has been demonstrated, and there is no reason to assume that overall resistance to all antibiotics will ultimately be the last step for Yersinia pestis. The development of antimicrobial resistance in Yersinia pestis has renewed interest in these three methods, but there are other methods that have been used for hundreds of years and are now confirmed by scientific research. The development of CMR in Yersinia pestis is thought to be a horizontal gene transfer in the middle of a flea host. Recent discoveries about the rebirth of bubonic plague in mainland China and that the plague pathogen is constantly developing resistance to our antibiotic arsenal suggest that we are now taking steps to prepare for the possible global spread of plague-resistant organisms. Mullion has been shown to have significant antibacterial activity against the pesticides Yersinia. Yersinia pestis is consumed by neutrophils and macrophages when it enters the body.
