“…High haplotype diversity in a 66-kDa protein gene for A. cantonensis (14 haplotypes) and A. malaysiensis (13 haplotypes) has also been observed in other genetic markers. Twenty cytb haplotypes have been reported for A. cantonensis from several parts of the world (Dusitsittipon et al, 2015;Yong et al, 2015;Dumidae et al, 2019). For the COI gene, 16 haplotypes were observed in A. cantonensis globally (Eamsobhana et al, 2017), and 9 haplotypes were observed in A. malaysiensis from Laos, Malaysia, Myanmar and Thailand (Rodpai et al, 2016;Eamsobhana et al, 2018).…”

“…Invasive snails and rodents are implicated in an increase in the distribution of A. cantonensis in Brazil (Thiengo et al, 2010), Spain (Foronda et al, 2010), China (Yang et al, 2013), Uganda (Mugisha et al, 2012), Japan (Tokiwa et al, 2013) and the United States (York et al, 2015). The hypothesis that Angiostrongylus has achieved global-scale dispersal with various organisms/hosts or vectors is largely influenced by human transportation (Monte et al, 2012;Tokiwa et al, 2012;Dusitsittipon et al, 2015).…”

“…The transmission of this nematode has been linked to the dispersal of invasive hosts (Tokiwa et al ., 2012 ). The increased presence of A. cantonensis in the country is likely a result of the rapid spread of its intermediate host, A. fulica , contributing to the dispersion of this parasite and infection of the definitive host (Thiengo et al ., 2010 ; Dumidae et al ., 2019 , 2021 ). Invasion by A. fulica facilitates the establishment of the life cycle of the parasite and thus increases the chances for exposure of native snails to A. cantonensis in existing endemic areas.…”

The rat lungworm Angiostrongylus cantonensis is globally known to be the cause of oeosinophilic meningitis in humans. Another congener, Angiostrongylus malaysiensis, is closely related to A. cantonensis and has been described as a potential human pathogenic parasite. These 2 worms are similar in terms of life cycle, host range and morphological and genetic information. However, there are limited studies about their genetic diversity based on the 66-kDa protein-encoding gene. The objective of this study was to explore the 66-kDa protein sequence variation of A. cantonensis and A. malaysiensis collected from Thailand. Two adult and 53 third-stage larval specimens of Angiostrongylus from 4 geographic locations in Thailand were molecularly identified using the 66-kDa protein gene. The phylogenetic trees (Bayesian inference tree and maximum-likelihood tree) showed that Angiostrongylus formed a monophyletic clade with a clear separation between A. cantonensis and A. malaysiensis. The genetic distance between A. cantonensis and A. malaysiensis varies from 0.82 to 2.86%, with a total of 16 variable sites. The analysis of genetic diversity revealed 1 and 5 new haplotypes of A. cantonensis and A. malaysiensis, respectively, and showed genetic differences between the populations of A. cantonensis and A. malaysiensis. The haplotype networks of A. cantonensis and A. malaysiensis populations in Thailand are similar to those of populations in some countries, indicating the range expansion of genomic origin between populations in different areas. In conclusion, the 66-kDa protein gene was a good genetic marker for studying genetic diversity and discriminating between A. cantonensis and A. malaysiensis.

“…Moreover, this introduction also encompasses research activities, for example, the exchange of genetic material, biological specimens, microbial culture collections and laboratory equipment. Several invasive mollusk species have been identified, such as Melanoides tuberculata (Purnama et al 2019(Purnama et al , 2022a(Purnama et al , 2022bBarros et al 2020;Khanam et al 2020;Lopes et al 2020;Okumura and Rocha 2020;Alfaro et al 2021;Lopes et al 2021;McClure 2021), and Achatina fulica (Gregoric et al 2011;Purnama et al 2019;Barbosa et al 2020;Oliveira et al 2020;Song et al 2020;Cano-Pérez et al 2021;Dumidae et al 2021) Their biological properties are highly resistant to water quality change, making them quickly colonize new environments.

Abstract. Purnama MF, Salwiyah. 2022. Short Communication: Invasive mollusks Melanoides tuberculata, and Achatina fulica in Southeast Sulawesi, Indonesia. Biodiversitas 23: 4770-4774. Southeast Sulawesi Province has natural/artificial inland waters for various usages. For example, freshwater has supported various activities such as agriculture, plantations, inland fisheries, and ecotourism. This study reports the presence of invasive mollusk in freshwater (Melanoides tuberculata) and terrestrial (Achatina fulica) habitats. This study is the first report regarding the spatial distribution of the three invasive mollusk species in the inland waters of Southeast Sulawesi, Indonesia. All administrative areas (17 districts/cities) in Southeast Sulawesi province were invaded by A. fulica and 16 districts/cities by M. tuberculata. These invasive mollusks species are a severe threat to the preservation of native species and human health because they are an intermediate host for several types of parasites, such as the trematode group. The spreading and rapid development of these invasive mollusks is caused by their reproductive ability and resistance to poor environmental quality and airborne dispersal factors by birds, water flow, and commercial activities. This invasive species can directly cause huge economic losses as they become a pest in agricultural activities, plantations, and freshwater fisheries (aquaculture). They also can transmit pathogens and displacement of native species. Therefore, it is recommended to have a preventive effort to tackle the expansion of IAS in Southeast Sulawesi.

Physella acuta is a freshwater snail native to North America. Understanding the phylogeography and genetic structure of P. acuta will help elucidate its evolution. In this study, we used mitochondrial (COI and 16S rDNA) and nuclear (ITS1) markers to identify the species and examine its genetic diversity, population structure, and demographic history of P. acuta in Thailand. Phylogenetic and network analyses of P. acuta in Thailand pertained to clade A, which exhibits a global distribution. Analysis of the genetic structure of the population revealed that the majority of pairwise comparisons showed no genetic dissimilarity. An isolation-by-distance test indicates no significant correlation between genetic and geographical distances among P. acuta populations, suggesting that gene flow is not restricted by distance. Demographic history and haplotype network analyses suggest a population expansion of P. acuta, as evidenced by the star-like structure detected in the median-joining network. Based on these results, we concluded that P. acuta in Thailand showed gene flow and recent population expansion. Our findings provide fundamental insights into the genetic variation of P. acuta in Thailand.
