The invasive giant African land snail,Achatina fulica(Gastropoda: Pulmonata): global geographical distribution of this species as host of nematodes of medical and veterinary importance

“…Artificial digestion was the method most used in 39 studies, making this method significantly ( P < 0.031) more frequent than any other (table 1). This technique involves the digestion of the A. fulica tissue in a solution of hydrochloric acid (HCl), with the resulting liquid being sedimented in a Baermann funnel for the isolation of the nematode larvae (Lim & Heyneman, 1965; Maldonado et al , 2010; Thiengo et al , 2010; Zanol et al , 2010; Rollins et al , 2021; Souza et al , 2021). Other methods were also used to extract the nematodes, including artificial digestion with pepsin ( n = 19 studies), which was most frequent ( n = 14) in Asia (Noda et al , 1987; Tujan et al , 2016; Lange et al , 2018; Penagos-Tabares et al , 2019; Jakkul et al , 2021).…”

“…Significantly ( P = 0.007) more studies were based on the collection of specimens during the daylight period ( n = 14 papers), in particular in South America (Moreira et al , 2013; Peng et al , 2017; Bechara et al , 2018; Ramos-de-Souza et al , 2018; Silva et al , 2020; Souza et al , 2021), with only five surveys being conducted at night (Lim & Heyneman, 1965; Morocoima et al , 2014; Cuasapaz-Sarabia, 2016; Peng et al , 2017; Bechara et al , 2018), and thirty-two studies did not specify the collection period (online supplementary file table S2). Five studies referred to the collection of specimens during the rainy season (Caldeira et al , 2007; Vitta et al , 2011; Andrade-Porto et al , 2012; Cuasapaz-Sarabia, 2016).…”

“…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.…”

“…;Epelboin et al, 2016;Igbinosa et al, 2016;Meffowoet et al, 2020) (fig.3, table 1).Other metastrongylid species were also recorded infesting A. fulica, including Aelurostrongylus abstrusus (Railliet, 1898), in Brazil, Argentina and Colombia (n = 8)(Thiengo et al, 2008;Oliveira et al, 2010;Andrade-Porto et al, 2012;Valente et al, 2017;Lima & Guilherme, 2018;Penagos-Tabares et al, 2019), Angiostrongylus vasorum (Baillet, 1866) in two studies from Colombia(Lange et al, 2018;Penagos-tabares et al, 2019) and Angiostrongylus malaysiensis Bhaibulaya and Cross 1971 in two studies from Thailand and one in Malaysia(Lim et al, 1976;Dumidae et al, 2019;Jakkul et al, 2021). No records of natural infection by Angiostrongylus costaricensis Morera and Céspedes, 1971 were found in any of the papers examined in the present study.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 thePhilippines 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 …”

Patterns of Gastrointestinal Helminth Infections in Rattus rattus, Rattus norvegicus, and Mus musculus in Chile

“…From an ecological standpoint, invasive rodents not only directly impact native communities by predation or competition (3), but they also indirectly impact communities by both introducing allochthones parasites or amplifying native ones (4). From an epidemiological and public health standpoint, rodents are important reservoir hosts of several zoonotic helminths (5)(6)(7)(8)(9), and, although several rodents can harbor zoonotic parasites (10)(11)(12), most of the reported zoonotic parasites have been found in invasive rodents (Rattus spp. and Mus spp.)…”
