This is an important study, and at this point we can clearly see the alanine mentioned in the Daszak paper coming through the nidoviral spikes at position 91. However, where this Daszak report goes to pangolin, we retain the science showing ivermectin’s physical attachment to position 91. The histidine at the SARS-CoV-2-ACE2 complex (position 378) is not as interesting as following the evolutionary history of ivermectin, only ever found on the Kawana golf course. Omura first used ivermectin against Nematospiroides dubius, a nematode whose generic name was changed to Heligmosomoides polygyrus. Heligmosomoides thomomyos infects the Camas Pocket Gopher, Thomomys bulbivorus, endemic to the Willamette Valley, Oregon. Wuhan bat lady and Daszak’s opposite number, Zheng-Li Shi, is published for white spot syndrome of shrimp (WSSV), recalling that Wuhan “Patient Zero” was supposedly a shrimp seller.
Indians called the Willamette the “Valley of Sickness,” and when the Missoula Floods once inundated the valley, the water was 400 feet deep, which would obviously permit establishment of crayfish. The nidovirus link to crayfish are yellow head virus (YHV) and gill-associated virus (GAV). Furthermore, following the ivermectin trajectory and noting that another animal that associates with the Camas pocket gopher is the long-tailed weasel. Once having made this connection, we note that Mustela coronavirus of ferrets not only links Danish mink farms, but also has, at position 91 of its spike (in both examples shown at Uniprot) is a (histidine [italics]).
