1 Introduction

The New Zealand mud snail Potamopyrgus antipodarum (Gray, 1853) (Gastropoda, Tateidae) has been present in Europe for about 160 yrs (Boycott, 1936), while in Poland, its first occurrence was recorded almost 100 yrs ago (Urbański, 1935). Currently, this is a species with a worldwide distribution (Collado, 2014) that causes numerous ecological and economic problems (Alexandre da Silva et al., 2019). Potamopyrgus antipodarum has also been presented among the one hundred worst invasive species in Europe (Nentwig et al., 2018). The latest models of potential distribution and areas susceptible to the invasion of P. antipodarum in South America and worldwide, regardless of positive and negative climate changes, show greater suitability of the environment, also outside the area of its current distribution (Alexandre da Silva et al., 2019).

One of the strategies that make the species an effective invader in a new area is parthenogenesis (i.e., asexual reproduction in which development of embryos occur without fertilization) (Jacobsen and Forbes, 1997). In the European populations, there is no evidence of sexual reproduction, although males of P. antipodarum have been found (Jacobsen and Forbes, 1997). The populations of parthenogenetic organisms can expand their range more efficiently while adapting to a new environment (Morgan-Richards et al., 2010). The parthenogenesis of P. antipodarum living outside native boundaries under favourable and stable conditions allows for a fast multiplication of specimens that become quantitative dominants among macroinvertebrates (Alonso and Castro-Díez, 2012). Städler et al. (2005) showed a marked divergence between the two European haplotypes of P. antipodarum, which means successful colonization by two distinct mitochondrial lineages. However, the samples of Polish origin have not been studied so far.

Ballast water is considered the main cause of the global spread of this invasive species (Alonso and Castro-Díez, 2008). However, the presence of the snail species in Polish water bodies as well as other non-endemic places, may result from other passive modes of its distribution in the spread of the individuals on birds' feathers or in fish intestines (Alonso and Castro-Díez, 2008). The success of P. antipodarum in inhabiting non-native areas is associated with a wide tolerance to different physicochemical conditions (e.g., pH, water temperature, dissolved oxygen), as well as the shell morphological adaptations and the lack of native enemies. For example, thanks to the solid operculum and strong shell, snails are able to survive in the digestive system of fish, as a result, these vertebrates are less effective as predators, and on the contrary, they can be the carrier of P. antipodarum (Alonso and Castro-Díez, 2012).

Very little has been proven about the use of P. antipodarum by parasites in its new areas (Larson and Krist, 2019). The snail is even considered as a potential biological control against some species of parasites such as bird schistosomes (Marszewska et al., 2018a). However, it should be taken into account that this snail species, reaching such huge densities (Dorgelo, 1987), may become a convenient host for local parasites. In the work of Kelly et al. (2009) a wide range of arguments is presented that nonindigenous animal species may be highly competent hosts for the indigenous ones.

The genetic structure of intermediate hosts of trematodes is of great interest to scientists (Hauswald et al., 2011; Tantrawatpan et al., 2020). The genetic variation between populations of P. antipodarum is reflected e.g. in differences in life-history traits (Jacobsen and Forbes, 1997). We examined specimens of this alien species from different localization in Poland to obtain pioneer knowledge about its mitochondrial haplotypes in the area of Central Europe, which we presented on the background of the recorded mitochondrial haplotypes in the world, and we checked the role of P. antipodarum as an intermediate host for digenean trematodes.

2 Material and methods

2.1 Research area and sampling

The samples were gathered in September 2018, that is, after months of the strongest release of cercariae from the first intermediate hosts (various species of freshwater snails) (Marszewska et al., 2018b; Cichy et al., 2019) for which P. antipodarum can play the role of the second intermediate host (Żbikowski and Żbikowska, 2009; Cichy et al., 2017). The study areas which we used for the research were water bodies from three different parts of Poland: western Poland − Lake Czaplino; central − Lake Iławskie and Lake Sosno; and southern Poland − a pond in Strzemieszyce Wielkie (a district of Dąbrowa Górnicza), as well as a bathing resort in the Valley of Three Ponds area in Katowice (Fig. 1). All of the lakes situated in the north part of Poland are natural water bodies, and the others are anthropogenic reservoirs that seem more attractive to P. antipodarum (Johnson et al., 2008). Also, the abiotic conditions of the environment are of great importance for the formation of mollusk populations (Larson et al., 2020), and therefore the values of physical and chemical parameters of water were measured during the study with the core sampler and a MultiLine P4 (WTW) Universal Pocket Sized Meter (Tab. 1). The sampling of P. antipodarum from a sandy bottom (up to a depth of 1.5 m) in each site was carried out using a metal sieve (mesh diameter 3 mm). Then the snails were transported to the laboratory in containers with lake water. The taxonomic affiliation of collected snails as P. antipodarum species was verified on the basis of morphological data (Piechocki and Wawrzyniak-Wydrowska, 2016).

2.2 Parasitological examination of snails

In each sample, we randomly isolated 200 individuals with a shell height of 4–6 mm from each research area for an autopsy. The snail shells were removed and the soft parts of the body were carefully examined for the presence of trematodes under a light microscope (Axio Lab.A1), whereas using the Axiocam 105 color camera and ZEN software, photographs and measurements were taken. The identification was made on the basis of the morphological characteristics of live parasite larvae. For this purpose, we used drawings, photos, and descriptions of parasites presented by various authors (Kanev, 1994; Gérard and Le Lannic, 2003; Faltýnková et al., 2007; Żbikowski and Żbikowska, 2009; Cichy and Żbikowska, 2016; Cichy et al., 2017).

The term “prevalence” is the percentage ratio of the number of infected individuals to the number of all collected P. antipodarum in a given water reservoir, calculated according to the formula: P [%] = n/N × 100 (P = prevalence, n = the number of infected individuals in a sample, N = the number of all collected individuals in a sample). The term “average intensity” is the average number of metacercariae recorded per infected individual, calculated according to the formula: AI = S/n (AI = average intensity, S = the sum of all larvae in a sample, n = the number of infected individuals in a sample).

2.3 DNA extraction, amplification and sequencing of P. antipodarum

DNA extraction was performed for five individuals of P. antipodarum from each research area, with the exception of Lake Sosno, in the case of which, 3 specimens were tested, using the Sherlock AX Kit (A & A Biotechnology, Poland). PCR generated a fragment of the 16S ribosomal RNA gene using the two primers, S1-Universal (5′-CGGCCGCCTGTTTATCAAAAACAT-3′) and S2-Potamo (5′-GTGGTCGAACAGACCAACCC-3′) (Städler et al., 2005). A PCR reaction of each sample was performed in a 20 µl reaction mixture, consisting of 3 µl of template DNA, 0.6 µl of each primer, 2 µl of 10× buffer, 13 µl of ddH2O, 0.6 µl of 20 mM dNTP (ThermoFisher Scientific, USA) and 0.2 µl of Taq-Polymerase (ThermoFisher Scientific, USA). PCR conditions consisted of 5 min initial denaturation at 92 °C, 30 s denaturation at 92 °C, followed by 60 s annealing at 55 °C, and 90 s elongation at 72 °C for 40 cycles followed by a final elongation step for 5 min at 72 °C. A 3 µl sample of PCR product was run on a 1.5% agarose gel for 30 min at 100 V to check DNA quality. PCR products were cleaned up by using Clean-up Kit (A&A Biotechnology, Poland). A sequencing reaction was performed in 10 µl of the reaction mixture, consisting of 2 µl of PCR product, 0.15 µl of primer, 1 µl of sequencing buffer (Brilliant Dye Terminator Sequencing Kit, Nimagen, The Netherlands), 5.85 µl of ddH2O and 1 µl of Terminator (Brilliant Dye Terminator Sequencing Kit, Nimagen, The Netherlands). The sequencing programme consisted of four steps: 1 min initial denaturation at 96 °C, followed by 10 s denaturation at 96 °C, 5 sec annealing at 55 °C, and 4 min elongation at 60 °C for 25 cycles. Sequencing products were cleaned up by using ExTerminator (A&A Biotechnology, Poland) and sequenced in one direction. The sequencing reactions were performed in the Genomed company (Warsaw, Poland). Sequences were deposited in GenBank with the following accession numbers: MK578223, MK578224, MK578225, MK578226, MK578227.

2.4 Alignment and statistical analyses

All available mitochondrial 16S ribosomal RNA (rRNA) sequences of P. antipodarum were downloaded from GenBank (Tab. 2). These sequences together with 23 newly obtained sequences were aligned by using MAFFT version 7 (Katoh et al., 2002; Katoh and Toh, 2008). A 16S dataset (436 bp length) comprises sequences from 16 countries (Tab. 2). To estimate the population genetic parameters (such as the number of haplotypes, polymorphic sites (S), nucleotide diversity (π), haplotype diversity (H)) calculations were performed in DnaSP v.5.10 (Librado and Rozas, 2009). Median Joining haplotype network (436 bp length of alignment) was performed in PopART (Bandelt et al., 1999). The haplotype networks were constructed from all haplotype sequences presented in each studied population. Haplotypes were shown as black circles, where the size of the circle represents the number of populations where they are present. Haplotypes are identified by numbers with # marks, white circles without a number indicate a hypothetical intermediate haplotype which is necessary to link observed haplotypes. Hatch marks in the network represent single mutations.

3 Results

3.1 Molecular examination

Based on all 16S rRNA sequences of P. antipodarum obtained from our samples, we observed that all of them belong to the same haplotype, defined in this study as haplotype 1 (Tab. 2, Fig. 2). Together with all available mitochondrial 16S ribosomal RNA sequences of P. antipodarum, we identified 22 distinct haplotypes. Haplotype 1 and 2 were most frequent, present in 11 and 6 countries, respectively. Apart from Poland, haplotype 1 was present in Germany, France, Hungary, Lithuania, Spain, Denmark, Italy, the Netherlands, Switzerland and the United Kingdom (UK), whereas haplotype 2 occurs in Estonia, the USA, Spain, Belgium, France and the UK (Tab. 2). Haplotypes from 3 to 17 and from 19 to 22 were restricted to water bodies of New Zealand, while haplotype 18 occurs in Tasmania (Australia). Population genetic parameters for P. antipodarum were S = 22; π = 0.00804; H = 1.000.

Haplotypes are represented by black circles, the size of which is proportional to the number of populations in which a particular haplotype is present. Populations are listed in Table 2. Haplotypes are from #1 to #22; white circles without a number indicate a hypothetical intermediate haplotype linking observed haplotypes. Hatch marks in the network represent single mutations.

3.2 Parasitological examination

We found three morphological types of metacercariae (Fig. SM 1, Tab. 3). They differed both in diameter and in the presence/absence of collar spines. The metacercaria of type I (from Lake Czaplino) was characterized by the outer diameter of cyst: 118 × 116 μm. Inside the cyst, we observed two suckers and we could not observe a stylet or collar spines. The metacercariae of type II were found in snails from Lake Iławskie and Pond in Strzemieszyce Wielkie, and they had the outer diameter of cysts: 149 (SE 0.9) × 148 (SE 0.7) μm and 150 (SE 0.5) × 148 (SE 0.5) μm, respectively. The metacercariae of type III recorded in Lake Sosno were much larger than the others (261 (SE 0.6) × 260 (SE 0.7) μm in diameter). All the larvae also had two rows of collar spines, but 4 spines at both edges of the collars were much larger than the other spines. The presence of these larvae was recorded in specimens from four out of the five investigated water bodies (Tab. 3). The prevalence ranged from 0.5% to 6%, and the average intensity from 1 to 2.5 larvae per one host snail (Tab. 3).

4 Discussion

A single parthenogenetic individual of P. antipodarum can colonize a new area by itself (Schreiber et al., 1998). These populations consist of “snail clones” because only new introductions and/or mutations can increase the diversity of the gene pool (Weetman et al., 2006). As a result, snail populations living outside their native range are characterized by low genetic diversity (Alonso and Castro-Díez, 2012). All P. antipodarum used in our studies represented the same haplotype, despite the fact that they came from five water bodies which are located at a substantial distance from each other. Our data is the first demonstration of the presence of 16S rRNA haplotype in Poland. In the case of the whole Europe, there are several clonal lineages presumably created as a consequence of the long invasion history (Alonso and Castro-Díez, 2012). Our analysis showed that the haplotype found in our research is the most widespread in Europe.

Potamopyrgus antipodarum individuals from our study were infected only with metacercariae. In New Zealand, P. antipodarum is widely used by many species of digenean trematodes not only as the second but also as a strongly specific first intermediate host (Hechinger, 2012). For example, Hechinger (2012) listed 20 species of digenean trematodes for which P. antipodarum plays the role of an intermediate host in its native area, with the prevalence up to 7%. By contrast, outside the native range, pre-patent or patent infection (infections with sporocysts, rediae or immature cercariae) is extremely rare (Evans et al., 1981; Gérard and Le Lannic, 2003; Żbikowski and Żbikowska, 2009). Recorded cases of such digenean infections found in P. antipodarum are the result of an introduction from their native areas (Gérard et al., 2017). We recorded a low prevalence of snails infected with metacercariae, similar to our previous study presented by Cichy et al. (2017). Because too few morphological features have been observed to identify the species of metacercariae found in Lake Czaplino, we were unable to determine whether it posed a medical or veterinary threat. Other metacercariae detected in P. antipodarum from our study were identified to belong to the family Echinostomatidae (Kanev, 1994; Faltýnková et al., 2007; Cichy and Żbikowska, 2016). Given the characteristics of metacercariae, we suspect that these larvae represent the genus Echinoparyphium and/or Echinostoma (Kanev, 1994; Faltýnková et al., 2007; Cichy and Żbikowska, 2016). There are several species of Echinostoma (e.g. E. revolutum, E. paraulum) and Echinoparyphium (e.g. E. recurvatum, E. mordwilkoi) in Europe, which at the stage of metacercaria cannot be distinguished without molecular methods (Georgieva et al., 2014). Members of these genera are quite common in the environment and use common snail species as first or second intermediate hosts (Cichy and Żbikowska, 2016). Echinostomes are widespread flukes causing intestinal diseases and they are mainly important in wildlife diversity (Saijuntha et al., 2010).

In conclusion, our research indicates the presence of only one 16S rRNA haplotype of P. antipodarum in Poland. Potamopyrgus antipodarum outside its natural occurrence is used as the second intermediate host of digenean trematodes; however, the detection of the association between the mtDNA haplotype of P. antipodarum and metacercarial infection should be investigated in detail in the future.

Haplotype Median Joining network for the 16S ribosomal RNA haplotypes of Potamopyrgus antipodarum. Haplotypes are represented by black circles, the size of which is proportional to the number of populations in which a particular haplotype is present. Populations are listed in Table 2. Haplotypes are from #1 to #22; white circles without a number indicate a hypothetical intermediate haplotype linking observed haplotypes. Hatch marks in the network represent single mutations.
