In this July 22nd webinar, Tom opens with an “urgent public service announcement” about what he calls “SIT,” or the “syndrome of insufficient thinking,” to comment on public health messaging and critical thinking.
Tom then discusses Cryptosporidium and gives a brief update on what it is and whether people need to be worried. Tom also announces that for the next four weeks, Wednesday webinars will be led by the specialists from the New Biology Clinic so viewers can hear from different members of the clinic team.
Highlights from this session include: -Tom reviews the conventional description of cryptosporidiosis as a diarrheal disease said to be caused by the microscopic parasite Cryptosporidium. -He examines the CDC-style explanation that Cryptosporidium spreads through contaminated water, infected stool, and contaminated foods such as fruits and vegetables. -He questions whether Cryptosporidium is truly a free-living organism or whether it may be a microscopic artifact related to tissue breakdown and staining techniques. -He compares the Cryptosporidium story to his previous discussion of the malaria parasite, where he argues that some so-called protozoan parasites may actually be artifacts of damaged tissue rather than independent disease-causing organisms. -He reviews papers on Cryptosporidium and highlights what he sees as weaknesses in the claim that the organism has been proven to cause disease. -He discusses the conventional shift from a simple germ-theory model toward a more complicated “host-pathogen interaction” model, arguing that this is a rescue device for the original germ theory. -He raises the possibility that environmental exposures, including wildfire smoke components, drugs, antibiotics, and other toxins, may better explain gastrointestinal symptoms than a single parasite.
Tom closes by saying he hopes the discussion gives viewers an overview of Cryptosporidium and helps them avoid fear around “cryptosporidium explosive diarrhea.”
