  • Felis tigris - The Indian tiger, well protected in Gir forests.
  • E.coli - Full name Escherichia coli, a commonly occurring bacterium in human intestine

Humans have acquired immune system that produces antibodies to neutralize pathogens. Still innate immune system is present at the time of birth because it

  •  is very specific and uses different macrophages,

  •  produces memory cells for mounting fast secondary response.

  •  has natural killer cells which can phagocytose and destroy microbes

  •  provides passive immunity.
