What Is The Best Treatment For Naegleria Infection?

Naegleria fowleri or Naegleria is a type of single-celled and heat-loving ameba present in the protozoa phylum referred as Percolozoa. As it is a type of free-living organism, it often lives in soil and fresh water, while consumes bacteria and other similar types of organic matter. The organism mainly undergoes three major stages in its entire life cycle i.e. flagellate, cyst and trophozoite.

When the organism remains in its cyst state, it is able to withstand almost freezing temperature and shows stability towards the environment. Next stage is the flagellate form i.e. an intermediate stage of the organism that moves only and does not intake any nutrient or nor reproduce further. Trophozoite form of Naegleria fowleri is the active reproducing and eating phase. (1)

Along with this, doctors recommend for the usage of artificial respiration techniques, like for instance the hyperventilation and the technique of induced coma to reduce swelling and provide protection to the functions performed by the patient’s brain while the main medicine kills the ameba.
