Naegleria fowleri is a free keep , flagellated freshwater ameba usually encounter in rivers , lake , geothermic springtime and spas , canals , strong water supply discharge from power plant and inadequately treat swimming pools and domestic water supplies . The denseness of the ameba increases during the hot summer month . The ameba feeds on bacteria and constituent debris . It can exist in three form , namely , cyst flesh ( static in the surroundings ) , trophozoite form ( motile ameboid physique ) and flagellate form.(1 )
Naegleria fowleri is also known as nous feeding ameba as this amoeba has a disposition to infix brain via nostrils . Mostly , the amoeba inscribe nostrils through contaminated water when this water is inhaled deep during swim , bound or diving in ameba contain water . N. fowleri invade brain via olfactory nerves and cribriform plate and causes extensive brain tissue paper damage within a few sidereal day leading to severe inflaming and hemorrhaging . This CNS involvement due to Naegleria fowleri infection is termed as primary amebic meningoencephalitis.(1 )
Naegleria fowleri is coined after an Australian pathologist , Malcolm Fowler who was the first to sequestrate it from a patient role with primary amebic encephalomeningitis . Bull was the one to term the disease by Naegleria fowleri “ main amoebic meningoencephalitis ” so that it could be differentiated from secondary cerebromeningitis , which is induce by Entamoeba histolytica , an enteric ameba . Although , 30 different specie of Naegleria have been recognized and other Naegleria species ( Naegleria italica , Naegleria australiensis , Naegleria philippinensis ) stimulate primary amebic meningoencephalitis in murine framework , only Naegleria fowleri has been isolated from human face , so far.(2 )
Naegleria fowleri infection is a rare disease with totality of 440 and 143 reported cases all around the macrocosm and United States by 2008 and 2016 , respectively . The risk of Naegleria fowleri infection is judge at 1 in every 2.6 million photo . Though , primary ameban meningoencephalitis is a rare disease , it is associated with high fatality rate , outdo over 95 % . Very few survivors have been reported in US ( 4 out of 143 until 2016 ) and worldwide ( total of 8 until 2005 ) . The rarified survivor were due to other designation and diagnosis help prompt belligerent interference . Most of the survivor are found with strong-arm or genial disability.(2 )
Symptoms Of Primary Amebic Meningoencephalitis
Although , most of the cases of elemental amebic meningoencephalitis have a previous account ofswimming , there have few cases where the disease fall out due to exposure to beg water in the form of ablution and use of neti pots . Infection should be suspected in children and young adults with a past history of swim in lake , pond and swimming syndicate . The symptom usually appear 2 - 6 days after exposure to polluted urine , particularly during summer months.(2 )
The sign and symptoms of primary amebous meningoencephalitis are similar to those of bacterial meningitis and include , pyrexia , nauseaorvomiting , change in sense of smell and taste , sudden headache ( in frontal and bitemporal region ) , neck stiffness , sensitiveness to lighter , vary mental position , hallucination , seizures , cranial nerve palsies , comatoseness and death . Positive Kernig and Brudzinski signal are also noted . master amoebic meningoencephalitis is unremarkably fatal . end normally occurs due to cardiorespiratory arrest andpulmonary edema . The progression of disease is rapid and death usually happens within 1 - 2 weeks of symptomatology . In recover patients , perseverance of seizure may be noted.(2 )
Since , the disease is acute , fulminant and black ; the endurance of a affected role with primary amoebous meningoencephalitis is largely strung-out on former diagnosis and aggressive treatment . The treatment is commonly done with anti - fungal medications , such as amphotericin B , Monistat , fluconazole and antimicrobial rifampin , in increase to ventriculoperitoneal electrical shunt in slip of hindering hydrocephaly . Amphoterin B is the drug of choice since Naegleria is known to be extremely sore to this antifungal drug . Various raw drug have been studied including Thorazine , miltefosine and corifungin that have prove efficaciousness against Naegleria species , both in vivo and in vitro . To keep off this calamitous infection , it is imperative to stay off from contaminated piddle and avoiding entry of water into nostrils.(2 )
