“…A number of other nematode species were found in association with A. fulica (fig. 3; table 1), such as Cruzia tentaculata (Rud, 1819), which was recorded in Brazil (Ramos-de-Souza et al , 2021), Ancylostoma caninum (Ercolani, 1859), found in both the Philippines and Brazil (Constantino-Santos et al , 2014a; Orico et al , 2019) and Strongyluris sp., with 11 records in Brazil and Argentina (Franco-Acuña et al , 2009; Maldonado et al , 2010; Oliveira et al , 2010; Lima & Guilherme, 2018; Oliveira & Santos, 2018; Ramos-de-Souza et al , 2018; Oda et al , 2020). In addition, some larvae were also reported in the faeces of A. fulica , not actually configuring mollusc infection.…”

“…The earliest paper was published in 1965, and the most recent, in 2021, with a progressive increase in the number of papers published after 2010, reaching a peak ( n = 8) in 2019. The studies identified in this search were concentrated in Southeast Asia, the Americas and the basins of the Pacific and Indian Oceans (Robinson, 2000), with the largest number of publications (25) being from Brazil (Caldeira et al , 2007; Thiengo et al , 2008; Barbosa et al , 2020; Silva et al , 2020; Ramos-de-Souza et al , 2021) (table 1) fig. 2.…”

“…In addition to being an intermediate host of nematodes that infect domestic animals, A. fulica may also be an intermediate host of the parasites of wild animals, which implies a threat to the local wildlife (Thiengo et al, 2008). In particular, Ramos-de-Souza et al (2021), reported the natural infection of A. fulica by C. tentaculata , a parasite of the opossums of the genus Didelphis Linnaeus, 1758.These authors also concluded that larvae of Strongylus sp., which were previously reported infecting terrestrial mollusks in Brazil are actually larvae of C. tentaculata .…”

The giant African land snail, Achatina fulica, is an important invasive species in many countries, where it causes losses in biodiversity and agriculture, as well as impacting the health of both humans and animals, as the intermediate host of medically important nematodes. The present study is based on a comprehensive review of the literature on the nematodes that have been found in association with A. fulica, worldwide. We searched a number of different databases and used the findings to investigate the methods used to extract and identify the nematodes, their larval stages, and environment and collecting procedures of the infected molluscs. Between 1965 and 2021, 11 nematode species were recorded in association with A. fulica in 21 countries. Most of the studies recorded associations between A. fulica and Angiostrongylus cantonensis, which causes cerebral angiostrongyliasis in humans and Aelurostrongylus abstrusus, which provokes pneumonia in felines. The nematodes were extracted primarily by artificial digestion with hydrochloric acid or pepsin, and identified based on their morphology or through experimental infection to obtain the adult. In most cases, the nematodes were at larval stage L3, and the infected A. fulica were collected from anthropogenic environments. The results demonstrate the importance of A. fulica as a host of nematodes of medical and veterinary importance, as well the contribution of anthropogenic environments to the occurrence of the parasites, and give information about the different methods used to collect and identify the nematodes found associated with this species.

“…In the case of the larvae that had previously been identified as Strongyluris sp., a recent study at the LRNEM ( 26 ), based on an integrated morpho-molecular analysis of the specimens, concluded that the samples identified as Strongyluris sp. did in fact represent Cruzia tentaculata (Rud, 1819) ( Figures 3E – G ), a parasite of the cecum of opossums ( Didelphis spp.)…”

An ample variety of parasitic associations are found between mollusks and nematodes, in which the mollusks may act as intermediate, paratenic or definitive hosts. Some free-living nematodes, in particular those of the order Rhabditida, are also found frequently in terrestrial mollusks. The present study reviews the results of the parasitological testing on samples of terrestrial mollusks conducted at the Brazilian National Reference Laboratory for Schistosomiasis and Malacology between 2008 and 2021. The samples were supplied primarily by the public health authorities from the different regions of Brazil, but also by research institutions and general population. The mollusks were processed individually and the obtained larvae were identified from their morphology and, whenever necessary, by molecular analysis. A total of 1,919 service orders were registered during the period, including 19,758 mollusk specimens collected from 23 of the 26 Brazilian states, as well as the Federal District, totalizing 145 municipalities. There was a marked predominance of the synanthropic species that are widely distributed in Brazil—Achatina fulica (87.08%), Bulimulus tenuissimus (4.18%), Bradybaena similaris (2.06%), and Sarasinula linguaeformis (1.50%). Of the 16,750 terrestrial mollusks examined, nematodes were recorded in 1,308 service orders, with the predominance of the superfamily Metastrongyloidea, in 616 service orders. They included Angiostrongylus cantonensis, rat lungworm, which was found in 252 samples, and Aelurostrongylus abstrusus in 145 samples. Free-living nematodes were found in 952 samples, Ancylostoma caninum and Cruzia tentaculata (previously identified as Strongyluris sp.) in one and 275 samples, respectively, and other parasites in 210 samples (not identified). The results highlight the diversity of the associations between nematodes and terrestrial mollusks in Brazil, in particular invasive and synanthropic species, with emphasis on the giant African land snail, Achatina fulica. They demonstrate the prominent role of this species of mollusk in the transmission of medically-important nematodes, which affect the health of both humans and animals, in particular eosinophilic meningitis, which is caused by Angiostrongylus cantonensis. This reinforces the need for more studies, and justify the growing demand for information as well as parasitological diagnosis of this mollusk, given its wide distribution in Brazil and its impact as an urban pest.
