The Komodo dragon is a very large species of lizard that lives on a few small islands in Indonesia. When the reptiles were first intensively studied, their hunting technique left many biologists puzzled because they simply bit their prey and then waited for it to slowly die. Experts started investigating the animal's mouths and they eventually suggested two possible explanations: massive bacterial load in their saliva or a specialized kind of venom. The first hypothesis was popular for many decades.
The first reason why massive bacterial load in their saliva seemed the more likely cause of death was that animals that had been bitten by Komodo dragons often had serious infections around the bites. Such infections would rapidly spread toxins throughout an animals' blood and kill it within a few days. Since the dragons are reptiles, and they can go for weeks between feedings, this strategy would work.
Second, the mouths of Komodo dragons are full of harmful bacteria. Researchers took samples of dragon saliva and analyzed it to see what bacteria were present. They found over 50 disease-causing pathogens (microorganisms like bacteria, viruses, and fungi that cause diseases), and when they injected the saliva directly into mice, many of the mice soon died. Samples of the mice's blood were full of the same kinds of bacteria.
Third, scientists believed that the bacteria allowed the dragons to catch much larger prey than their usual diet. Komodo dragons normally eat pigs and deer, which quickly die from blood loss when bitten. However, humans introduced water buffalo to the dragons' habitat. Water buffalo are so much larger than the dragons that they are difficult to kill. A massive bacterial load would turn otherwise survivable wounds for the buffalo into a slow death from bacterial infection.
Both the reading passage and the lecture discuss about the Komdo Dragons method of killing the preys. While the reading suggests that komdodo kills by loading tremendous amount of saliva full of bacteria, the lecture contradicts that by explainng how gradons use particular type of venom.
First of all the speaker suggests that bacterial theory is week since it is not based on real evidence or tests. On the other hand, the scientist studied venom in the lab by putting the animals into a scan and they found venom glands between the teeth. This contradict with the reading passage which states that Komdo cause sever infections to their preys after bitting them, since their saliva is full of bacteria. Eventually that lead to serious infections to the preys.
Secondly. the professor points out that harmful bacteria is not form the animal itself. It actually exists in the meat which they feed on. Not only this but, other prys like baffao catch the infection form the water. Again this contradicts with the reading passage which states that Komodo dragons mouth contains a lot of harmufull bacteria, that varies to cause fivteen different kind od diseas.
Finally, the lecture explains that after the komodo dragons bite their preys the wound become open and that helps them to distribute their venom into the prey's body. As a result, the blood pressure decrease and prevent open wound from closing. Eventually, the animal get into state of shock and finally dies. On the other hand the reading passage mentions that Komodo were able to catch large preys because of the lare amount of bacteria that get into their bodies and generate bacterial infection.
