Eosinophilic meningitis caused by Angiostrongylus cantonensis: an emergent disease in Brazil

Abstract

Eosinophilic meningitis (EoM) is an acute disease that affects the central nervous system. It is primarily caused by infection with the nematode Angiostrongylus cantonensis. This infection was previously restricted to certain Asian countries and the Pacific Islands, but it was first reported in Brazil in 2007. Since then, intermediate and definitive hosts infected with A. cantonensis have been identified within the urban areas of many states in Brazil, including those in the northern, northeastern, southeastern and southern regions. The goals of this review are to draw the attention of the medical community and health centres to the emergence of EoM in Brazil, to compile information about several aspects of the human infection and mode of transmission and to provide a short protocol of procedures for the diagnosis of this disease.

Parasites of edible land snails in Edo State, Nigeria

“…In human-infected cases, most damages are seen in the intestinal walls resulting in abdominal pain and fever (Graeff-Teixeira et al, 1991). Eosinophilic meningoencephalitis has been reported in both man and animals (Morassutti et al, 2014). Alaria parasites were isolated from some of the snails.…”

Caramujo Africano: Apenas Uma Espécie Introduzida Ou Um Problema De Saúde Pública?

“…(Chen, 1935) Esse nematoide é comum em países do sudeste asiático e ilhas do Pacífico. Seu primeiro registro no continente americano foi em Cuba, e, posteriormente na Jamaica, Estados Unidos e Equador (MORASSUTTI et al, 2014). De acordo com Diaz (2008), a introdução desse parasito no continente americano ocorreu em containers transportados por navios durante o período pós-guerra.…”

“…As larvas perfuram a parede do intestino a caem na corrente sanguínea, e, normalmente alojam-se nas meninges do sistema nervoso central, onde sofrem mais duas mudas e morrem. Para maiores detalhes acerca da fisiopatologia veja Morassutti et al (2014).…”

Characterization of the N-glycans of female Angiostrongylus cantonensis worms

“…In this study we used TE of the female A. cantonensis worms as the main antigen used for immune diagnosis of CA, 31-kDa compound, derives from this extract (Morassutti et al, 2014). A total soluble extract (TE) was obtained from harvested female A. cantonensis worms that were macerated in liquid nitrogen M A N U S C R I P T…”

“…Eosinophilic meningoencephalitis (EoM) is caused mainly by the nematode Angiostrongylus cantonensis, referred also as cerebral angiostrongyliasis (CA), which is endemic in many parts of the world, particularly in tropical and subtropical countries (Morassutti et al, 2014;Wang et al, 2012Wang et al, , 2008.…”
