“…Despite the previously proven susceptibility of Achatina fulica to Angiostrongylus costaricensis (Carvalho et al, 2003), this nematode was not detected in tested samples. This was expected, once there are no reports of snails naturally infected by Angiostrongylus costaricensis in the Americas (Pavanelli et al, 2017).…”

“…Listed among 100 of the worst invasive species by the Global Invasive Species Database (2019) (GISD, 2019), the giant african snail, Achatina fulica (Bowdich, 1893) is known for promoting environmental imbalance and substantial biodiversity and economic losses in the areas it has been introduced (Ohlweiler et al, 2010;Pavanelli et al, 2017).…”

“…Originated from east Africa, these molluscs were driven to the worldwide distribution since the 1800, reaching Asia in the middle of 1920s, the USA in the 60s and Guadeloupe in 1988 (Thiengo et al, 2007;Roda et al, 2016). They were illegally introduced in Brazil between 1988 and 1989, as a commercial alternative to the Helix aspersa (Müller) snail to be consumed as escargot (Thiengo et al, 2007;Pavanelli et al, 2017). The commercial collapse of breeders led to the inappropriate release of specimens and consequent dissemination in most of Brazilian territory.…”

Achatina fulica snails cause environmental problems and represent a public health hazard since it is a host in the life cycles of various parasites, among them, Angiostrongylus cantonensis and, less frequently, Ancylostoma caninum. We report the occurrence of Angistrongylus cantonensis, as well as the unexpected finding of Ancylostoma caninum, in a total of 936 specimens of Achatina fulica snails from different regions of São Paulo city, Brazil. Samples were divided into 492 pools which were screened for nematodes. If present, larvae were submitted to DNA extraction and PCR protocol targeting, the ITS-2 gene junction. From the 183 positive pools for larvae presence, 97 showed specific 650 bp band at electrophoresis and 21 presented bands nearly 300 bp. Two amplicons from each size were and sequenced. A BLAST/n of 650 bp sequences presented identity with Angistrongylus cantonensis, while the two of 300 bp, showed identity with Ancylostoma caninum, also supported by phylogenetic analysis. This is the second report of Ancylostoma caninum found in these snails in the world, therefore, this study allows a better understanding about these diseases and highlights the need of continue systematically mapping sites that can be infested with the mollusc.

“…Not only have A. cantonensis and A. malaysiensis been reported in A. fulica , but it is also a crucial vector known to harbor A. cantonensis and A. costaricensis ( Carvalho et al, 2003 ; Caldeira et al, 2007 ). Notably, the distribution of A. fulica may be useful to predict the host-parasite association of parasite transmission ( Pavanelli et al, 2017 ).…”

Angiostrongylus cantonensis is a well-known pathogen causing eosinophilic meningitis associated with angiostrongyliasis. Humans, as accidental hosts, are infected by consuming undercooked snails containing third-stage larvae. A. malaysiensis is closely related to A. cantonensis and has been described as a potential human pathogen. The two species distribution was recently reported to overlap in the same endemic area, particularly in the Indochina Peninsula. Similar morphological characteristics of the third-stage larva in the snail-intermediate host often lead to misidentification of the two species. Thus, we aimed to develop a sensitive and specific method to detect and discriminate Angiostrongylus third-stage larva by designing species-specific primers based on the mitochondrial cytochrome b gene. We developed the SYBR Green quantitative real-time PCR (qPCR) method for two species-specific detection assays, which could be conducted simultaneously. The method was subsequently employed to detect and identify third-stage larvae of Angiostrongylus isolated from infected Achatina fulica collected from six public parks in Bangkok Metropolitan, Thailand. The method was also a preliminary applied to detect parasite tissue debris in the patients' cerebrospinal fluid (CSF). SYBR Green qPCRs quantitatively detected approximately 10 −4 ng of genomic DNA from one larva, facilitating species-specific detection. Based on the pools of third-stage larvae isolated individually from the tissue of each infected A. fulica collected from the public parks, the qPCR results revealed that A. malaysiensis was the predominant species infecting 5.26% of the collected snails. In comparison, coinfection between A. malaysiensis and A. cantonensis was 5.97%, and no single infection of A. cantonensis was detected in A. fulica . Our SYBR Green qPCR method is a useful and inexpensive technique for A. cantonensis and A. malaysiensis discrimination, and the method has sufficient sensitivity to detect isolated larvae from a snail-intermediate host. The ratio of A. cantonensis and A. malaysiensis larvae infecting the snails can also be estimated simultaneously. Our qPCRs can be employed in a molecular survey of A. cantonensis and A. malaysiensis within intermediate hosts and for clinical diagnosis of angiostrongyliasis with CSF specimens in future studies.

“…En este trabajo estarían permeando la percepción de la comunidad sobre la problemática, pues dependen de la disponibilidad de información científica adecuada. Aunque en Colombia, la información generada sobre el caracol gigante africano y su proceso de divulgación exhiben las mismas tendencias a lo establecido para Brasil (Colley and Fischer 2009;Fischer et al 2015;Pavanelli et al 2017), el volumen de la información científica disponible es escaso.…”

RESUMEN.La presencia del caracol gigante africano (Achatina fulica) como especie exótica en Colombia desde 2008 ha impulsado alertas sociales, acciones de control y esfuerzos de investigación sobre diferentes aspectos de la historia natural bajo las condiciones ambientales del territorio nacional. Con el propósito de consolidar el conocimiento generado y divulgado acerca del caracol gigante africano en Colombia durante los 10 años de presencia, se buscó información en las principales bases de datos científicas y públicas a nivel nacional e internacional. Esta información se filtró según la fuente, el año, la zona y el tema, y se analizó la variación temporal de los reportes de presencia y control. La mayor parte de la información disponible proviene de los medios de comunicación. Se establecieron los años 2014 y 2016 como los de mayor divulgación, predominando temas de manejo y control, seguidos por los registros de presencia. De acuerdo con la cronología de la información consolidada se soporta la hipótesis de la entrada del molusco al país. Se encontró una relación entre la frecuencia de los registros de presencia con procesos climáticos de escala interanual (e.g., ENOS) e intra-anual (e.g., variación estacional asociado a la dinámica temporal de la zona de convergencia intertropical). Además, se detectó que aunque se le dio una prioridad mayor a las estrategias de control mediado por la comunidad, no se generó aún suficiente conocimiento científico sobre las características biológicas y ecológicas de la especie, en relación con las condiciones ambientales del país.
