NAEGLARIA FOWLERI: THE BRAIN EATING AMOEBA? Primary amebic meningoencephalitis (PAM) is a devastating yet rare hemorrhagic infection of the brain caused by Naeglaria Fowleri, the only know amoeba to infect humans. PAM is associated with a rapid onset even in healthy individuals, who have been swimming in freshwater such as swimming pools, lakes and streams. For this reason, it has the potential to be an outbreak in New Zealand. Naeglaria Fowleri is only able to infect individuals through entering the navel passages, from here they attach to the nasal mucosa, which allows the amoeba to travel through cribriform plate using the olfactory nerves, resulting in access to the frontal lobe. The result of which is a sudden onset of bi-frontal or bi-temporal headaches, nausea, and irritability. However, seeing that the amoebae gain access to the frontal lobe relatively quickly leads to hemorrhagic necrosis and purulent exudates, which is a high protein concentration fluid that is released in cell necrosis, more commonly known as pus. The Astonishing factor about Naeglaria Fowleri is the fact that an onset can occur within 24 hours and death, with exception of one case usually occurs within a week making PAM very dangerous to New Zealand. Seeing that Infection can occur in any person who has been swimming in infected waters, as humans hold not innate defenses against the amoeba. Previous cases like those seen in 1984 happened with a 10-day period and effected those who had been…

varies 10-100nm.Unlikely prokaryotes, which have a certain shape, eukaryotes do not really have a specific shape that is defined. Organelles are the things that make eukaryote cells to be eukaryote. Eukaryote cells consist of: mitochondria, Golgi, ER, vacuoles, chloroplasts, lysosomes, nucleus, etc. The organelles that a cell has might vary from the type of the cell. Unfortunately, not all the parts of the cell might be observed under the light microscope because only the large organelles can be…

nature, but it was not an easy job for the artist. Valentine highlights that this sculpture was “composed of bent plywood foundation constructed with the help of glue, clamps, and high frequency microwaves and sheathed in mesh.” In other words, Puryear had to collaborate with other people to help him build this masterpiece. Valentine writes that Puryear said “That’s putting yourself in the hands of other people and trusting their skill and willingness to do what you want.” Here, we see that…

for food. Although the peranema is closely related to Euglenas, there were no signs of a chloroplast present or any sort of a green colour, so the peranema may have been a heterotroph and so it cannot be autotrophic. Similar to euglenas, peranema also reproduces asexually by binary fission. The way that peranema might feed would be from drawing food particles into their body. The expected outcome would have been that it was an Euglena, but from further research, it was not, which was expected…
