The Naegleria Fowleri Amoeba - 1013 Words

Introduction The Naegleria fowleri amoeba resides in lakes, rivers, thermal springs, dirty swimming pool and sometimes soil. The amoebas thrive during the summer months due to the increase of temperature(Shakoor, Beg, and Mahmood 258). Naegleria amoeba infects and targets brain tissue of the central nervous system and the neuromuscular system. The central nervous system is responsible for integrating and responding to neural signals. The nervous system and muscles in the body work together to permit movement called the neuromuscular system. The brain is the main control for integrating sensory neurons and coordinating body functions: voluntary and involuntary. When needed to move a body part, a message is sent to the afferent sensory neurons, which go through the brain and into the spinal cord where the efferent motor neurons send an electrical signal to trigger the muscle to contract. Errors such as sliding of the actin and myosin filaments or failure to release neurotransmitters from the neuron can happen. The infection causes primary amebic meningoencephalitis (PAM) (Shakoor, Beg, and Mahmood 258).. It cannot be contracted by person-to-person, or by drinking contaminated water. The amoeba enters the body via nose by infected water and/or dust and penetrates the cribriform plate(Shenoy, Wilson, and Prashanth [Page 309]). It travels to the brain by the nerves that transmit olfactory senses and causes PAM. It causes brain tissue damage and inflammation of the brain.

Out of the numerous species of Naegleria, only the single-celled fowleri is of vital concern to human health. This free-living ameboflagellate can be discovered in one of three stages depending on its surroundings (Fero 2010). The protozoan’s life cycle consists of a cystic phase which is resistant, a dormant biflagellate phase, and the dangerous trophozoiteRead MoreNaegleria Fowleri and Solid Organ Transplantation668 Words   |  3 PagesNaegleria fowleri and Solid Organ Transplantation – An Overview Naegleria fowleri commonly referred to as the â€Å"brain-eating amoeba†, is a free-living, warm fresh water amoeba, isolated from soil. Site of entrance of N. fowleri is when contaminated water moves up the nose, during swimming,nasal irritation, amoeba then passes the cribriform plate and reaches the brain causing primary amebic meningoencephalitis (PAM).128 Cases were reported from 1962 -2012 in U.S.PAM usually affect young,healthy individualsRead MoreTthe Role of Amoeba in Human Disease805 Words   |  3 PagesReview the Role of Amoeba in Human Disease Introduction Free-living amoebae (FLA) are eukaryotic organism found ubiquitously in nature. They are found in soil (dust), air, water and air, which provide amoeba multiple opportunities to spread (c). These can be pathogenic or non-pathogenic. Pathogenic FLA can invade and cause opportunistic and non-opportunistic infections in humans, which are found in the genus Acanthamoeba, Balamuthia mandrillaris, Naegleria fowleri, and Sappinia pedata (b).

The bacteria travel to your brain after entering the body through the respiratory system (Karriem-Norwood, 2014). According to the Centers for Disease Control and Prevention, parasitic meningitis is caused by an amoeba entering the brain and destroying brain tissue. The amoeba enters through the nose and can only infect humans in the first stage of its life cycle, in which they are known as ameboid trophozoites. They are single-celled organisms and they reproduce by promitosis. They are alsoRead MoreN Fowleri Consists Of An Amoeba2180 Words   |  9 PagesThe trophozoite of N fowleri consists of an amoeba surrounded by a two-layer membrane. The cytoplasm contains free and bound ribosomes, as well as membrane-bound organelles. A smooth endoplasmic reticulum, a Golgi-like structure, mitochondria, vacuoles, and nucleus-containing nuclear envelope are present. Microfilaments create a supportive cytoskeleton. The N fowleri flagellate is pear-shaped. The cytoplasm has fewer vacuoles, and the components of a flagellar apparatus (flagellum, basal body, rootlet)
