Part 1: It’s in your local pond, it loves a summer swim, and it has come to eat your BRAINZZZZZ…….!!! .
is a seemingly harmless, free-ranging #amoeba
that lives in water and just wants a bit of warmth and its favorite food, bacteria, to enjoy. Though occasionally, Naegleria can also be found haunting our media outlets. And our #brains
. It happens during #summertime
. While swimming in a lake or pond, a VERY unlucky person has managed to infect themselves with these creatures. And an #infection
with Naegleria Fowler is no laughing matter. These animals will crawl inside a human’s skull and devour the delicious, gooey, grey matter inside… Killing 99% of all infected victims in a time span of just under two weeks. .
Now, the amoeba doesn’t do this out of spite. It just wants a bit of food! Exploration of a strange, new world is just a lot more enjoyable when you don’t have to do it on an empty stomach. .
After it gets inhaled the teeny-tiny creature twists its little #flagella
into a little propeller. Then it moves up through the nose towards the olfactory nerve. This #nerve
is responsible for signaling smells and odors towards the brain. The amoeba reaches this nerve. What scrumptiousness! A tiny bite won’t hurt, Naegleria thinks, as it munches its way towards the #skull
The olfactory nerve is the back-door entry to the #brain
. The brain fends of infectious agents or toxic molecules through the #BloodBrainBarrier
. But to convey the sensation of smell to the brain, the olfactory nerve must get past that barrier. To do this, it passes the #CribiformPlate
- know where this is?). This is the part of the skull separating nose from brain. The cribiform plate has little holes, which allow the olfactory nerve to pass through. And so, as Naegleria keeps munching, it follows the trail of olfactory nerve tissue crumbs straight through the plate – and into the skull, to feed on the brain. .
