Naegleria fowleri, colloquially known as the brain-eating amoeba, is a species of the genus Naegleria. It belongs to the phylum Percolozoa and is technically classified as an amoeboflagellate excavate,[1] rather than a true amoeba. This free-living microorganismprimarily feeds on bacteria but can become pathogenic in humans, causing an extremely rare, sudden, severe, and usually fatal brain infection known as naegleriasis or primary amoebic meningoencephalitis (PAM).[2]

Incest (/ˈɪnsɛst/ IN-sest) is human sexual activity between family members or close relatives.[1][2] This typically includes sexual activity between people in consanguinity(blood relations), and sometimes those related by affinity (marriage or stepfamily), adoption, or lineage. It is forbidden and considered immoral in most societies, and can lead to an increased risk of genetic disorders in children in case of pregnancy.
