Part 1- Chapters 1- 9 Question 19

How did the mixture of monkey samples and species contribute to the hypothesis about
HIV being a hybridized or mixed-origin virus?

  1. Ebola is a virus that is related to HIV ;it destroys the immune system. Ebola is also similar to Marburg ,as shown in an experiment with Gene Johnson; they can infect hosts by traveling through the air. Marburg had a Cardinal strain that could reproduce in many different hosts like humans, monkeys, and guinea pigs; Ebola is the same where it can't tell the difference between a human and a monkey. When Patricia Webb, a C.D.C. virologist, put a an Ebola ridden blood from a nun into monkey cells, the cells burst. These viruses can jump species back and forth; it knew that meat was meat. The ability to jump species allowed the possibility that HIV was created in the same way. Also a virus wouldn't want to kill its host, so the original virus was created and jumped into another species; the new infected species would be destroyed and if HIV is like Ebola then it could mutate when jumping (Preston 1995). If HIV can jump species as well, then it would make sense if the monkey trade was the cause for HIV. The trade had the environment to thrive, which was a tight space of different species of monkeys. HIV is related to Ebola, so it seems plausible.

    1. Hi Helen, to be clear, Ebola is NOT related to HIV. Ebola belongs to the Filoviridae family while HIV belongs to the Lentivirus famiy- genetically very different from each other.
