“…Clinical and epidemiological details have been presented elsewhere for six of the patients. [25][26][27][28][29] Five patients had knowingly ingested raw snails: four as part of exotic cuisine, one as a dare. Two patients were part of an outbreak in Jamaica where a Caesar salad was implicated as the source of infection.…”

Abstract. Angiostrongylus cantonensis is the most common infectious cause of eosinophilic meningitis. Timely diagnosis of these infections is difficult, partly because reliable laboratory diagnostic methods are unavailable. The aim of this study was to evaluate the usefulness of a real-time polymerase chain reaction (PCR) assay for the detection of A. cantonensis DNA in human cerebrospinal fluid (CSF) specimens. A total of 49 CSF specimens from 33 patients with eosinophilic meningitis were included: A. cantonensis DNA was detected in 32 CSF specimens, from 22 patients. Four patients had intermittently positive and negative real-time PCR results on subsequent samples, indicating that the level of A. cantonensis DNA present in CSF may fluctuate during the course of the illness. Immunodiagnosis and/or supplemental PCR testing supported the real-time PCR findings for 30 patients. On the basis of these observations, this real-time PCR assay can be useful to detect A. cantonensis in the CSF from patients with eosinophilic meningitis.

RESUMOEsta revisão objetiva alertar e informar a população em geral e os profissionais de saúde quanto à atuação do caramujo africano [Achatina fulica (Bowdich, 1822)], como hospedeiro intermediário, na transmissão de nematoides de interesse veterinário e humano. Também demonstra o papel das conchas como criadouros para mosquitos vetores de diversas viroses, algumas inclusive com alta incidência no norte e noroeste fluminense.Palavras-chave: Achatina fulica; Controle de Caramujos; Zoonoses. ABSTRACTThis review aims at alerting and informing the general population and health professionals about the acting of the African snail [Achatina fulica (Bowdich, 1822)] as an intermediate host in the transmission of nematodes of veterinary and human interest. It also demonstrates the role of shells as breeding sites for mosquito vectors of various viruses, some of which are also highly prevalent in the north and northwest of the state of Rio de Janeiro.

“…These data are especially useful and can be used by public health authorities to establish policies related to surveillance and planning of preventive actions. Isolated cases of eosinophilic meningoencephalitis have recently been reported in Brazil 9,11,14,15,46,47 . Thus, it is plausible that A. cantonensis continues to spread to new regions, increasing the risk of eosinophilic meningoencephalitis in humans.…”

Introduction: Angiostrongylus cantonensis causes eosinophilic meningoencephalitis in humans. Worldwide expansion of this nematode is linked to the dispersion of their hosts. This study aimed to determine the prevalence of A. cantonensis infection in Achatina fulica in the nine municipalities that make up Baixada Santista, São Paulo, Brazil. Methods: Angiostrongylus cantonensis larvae were analyzed using optical microscopy. We performed polymerase chain reaction and restriction fragment length polymorphism using restriction endonuclease ClaI, directed to the internal transcribed spacer region 2 of A. cantonensis larval DNA. Results: Of the 540 snails analyzed, 117 (21.7%) were infected by A. cantonensis. For morphological and morphometric analyses, 60 larvae were used. Second-stage larvae were, on average, 358.2µm long and 26.4µm wide, while third-stage larvae were, on average, 450µm long and 21.12µm wide. The tails of the larvae ended in a fine tip. Conclusions: All municipalities comprising Baixada Santista had A. fulica that were naturally infected with A. cantonensis. All of the observed characteristics were typical of the species.
