Poisonous or notPoisonous or not ?
• Poisonous animal :
Some specialists think that is vevom which kills prays
• Virulent bacterias :
Others think that prays died by wound infection due to the bacterias inside dragons' mouth and also because buffalos run into water when attacked.
BacteriasBacterias ?A Komodo dragon's saliva can contain anywhere from 50 to 80 different bacteria. With that much bacteria entering the bloodstream through a bite, bacterial infection and death are guaranteed.
But Bryan Fry, from the University of Queensland, have shown that the level of bacteria in a Komodo dragon's mouth proved to be even lower than many mammalian mouths, especially those of carnivores. The dragon's mouth, he found, was kind of...clean.
PoisonousPoisonous ? ?In 2009, the Associate Professor Bryan Grieg Fry and is team found :
- presence of two glands in the lower jaw
- secreted several different toxic proteins
=> inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness
VENOM very similar to Gila Monster
