BackgroundThe rat lungworm Angiostrongylus cantonensis can cause eosinophilic meningoencephalitis in humans. This nematode’s main definitive hosts are rodents and its intermediate hosts are snails. This parasite was first described in China and currently is dispersed across several Pacific islands, Asia, Australia, Africa, some Caribbean islands and most recently in the Americas. Here, we report the genetic variability among A. cantonensis isolates from different geographical locations in Brazil using mitochondrial cytochrome c oxidase subunit I (COI) gene sequences.MethodsThe isolates of A. cantonensis were obtained from distinct geographical locations of Brazil. Genomic DNAs were extracted, amplified by polymerase reaction, purified and sequenced. A partial sequence of COI gene was determined to assess their phylogenetic relationship.ResultsThe sequences of A. cantonensis were monophyletic. We identified a distinct clade that included all isolates of A. cantonensis from Brazil and Asia based on eight distinct haplotypes (ac1, ac2, ac3, ac4, ac5, ac6, ac7 and ac8) from a previous study. Interestingly, the Brazilian haplotype ac5 is clustered with isolates from Japan, and the Brazilian haplotype ac8 from Rio de Janeiro, São Paulo, Pará and Pernambuco states formed a distinct clade. There is a divergent Brazilian haplotype, which we named ac9, closely related to Chinese haplotype ac6 and Japanese haplotype ac7.ConclusionThe genetic variation observed among Brazilian isolates supports the hypothesis that the appearance of A. cantonensis in Brazil is likely a result of multiple introductions of parasite-carrying rats, transported on ships due to active commerce with Africa and Asia during the European colonization period. The rapid spread of the intermediate host, Achatina fulica, also seems to have contributed to the dispersion of this parasite and the infection of the definitive host in different Brazilian regions.

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.

“…Achatina fulica , one of the hundred most harmful invading species on the planet 1 , native to East Africa, is known to have a highly predatory food and reproduction habits and have contributed to the extinction of native fauna and the decrease in biodiversity. The mollusk may cause heavy economical liabilities due to its proliferation in cash crops, gardens and kitchen gardens 2 .…”

“…In fact, the giant African snail is abundant in areas featuring high population density 2 , 6 . In addition, it should be underscored that the mollusk is a threat to public health since it harbors parasite vectors such as the nematodes Angiostrongylus cantonensis (Chen, 1935) which is the etiological agent of eosinophilic meningitis, and A. costaricensis (Morera & Céspedes, 1971) which causes abdominal angiostrongyliasis 2 , 5 , 7 .…”

The dissemination of the giant African snail Achatina fulica in several countries has triggered a great number of studies on the mollusk, including those on zoonoses related to health in humans. The current research is a scientific survey on articles published in four databases, namely, PubMed, Bireme, Scielo and Lilacs. Results indicate that Brazil has a prominent position in international scientific production on this subject, with focus on Angiostrongylus cantonensis occurrences.
