The vultures belong to the so-called scavengers, of which the habit of eating carrion is known.
The carcasses they feed on are clearly a receptacle of bacteria and other microorganisms, some of which can trigger dangerous infections.
The vultures are immune to these pathogens thanks above all to a very high gastric acidity, ten times higher than the human one, and therefore capable of destroying almost all of the ingested microbes.
In fact, the low gastric pH also represents a defensive barrier for humans against potential pathogens ingested with food.
Only the bacterium Helicobacter pylori has the ability to live permanently in the human stomach under normal conditions. Conversely, hypochloridria conditions (low gastric acidity) favor the growth of various bacterial strains at the gastric level.
