Database on eukaryotic symbionts of native and invasive gammarids (Crustacea, Amphipoda) in the Baltic region of Poland with information on water parameters for sampling sites.
This dataset documents the diversity of eukaryotic endo- and epibiotic organisms from 612 host individuals of seven gammarid (Amphipoda) species () of native and invasive origin in the Baltic region of Poland. We identify 60 symbiotic species of nine phyla from 16 localities of freshwater and brackish habitats. Twenty-nine symbiotic species belonged to the Ciliophora, 12 to Apicomplexa, 8 to Microsporidia, 3 to Platyhelminthes, 2 to Acanthocephala, 2 to Nematoda, 2 to Rotifera, 1 to Choanozoa and 1 to Nematomorha. The material in this Data in Brief paper is composed of three Microsoft® Excel files. The first file represents the raw data on the number of individuals (infrapopulation size) of each eukaryotic symbiont taxa recorded in each host individual and location. The data set contains information on the assemblage of symbionts per host individual in one table-matrix; macro- (host) and symbiont taxa name, host length, the date of collection, the geographic coordinates and locality name in columns; and amphipod host specimens in lines. The second file reports the symbiont species list (the species breakdown by phyla in spreadsheets) with information on host species, sampling date, locality and geographic coordinates, infection site, obtained sequences (if the case), brief morphological characteristics and microphotographs. The third file reports measured water parameters, habitat features and host density per sample. We generate the present dataset to evaluate the richness, diversity, population and community features of symbiotic organisms in native and invasive gammarid hosts in Poland.

A molecular and ecological study of Macracanthorhynchus ingens (von Linstow, 1879) (Acanthocephala: Archiacanthocephala), in its paratenic and definitive hosts in southeastern Mexico and the Eastern USA.
The acanthocephalan Macracanthorhynchus ingens (von Linstow 1879) (Acanthocephala: Archiacanthocephala) is a parasite that infects the gut of carnivores (racoons, coyotes, wolves, foxes, badgers, skunks, opossum, mink and bears) as an adult and the body cavity of lizards, snakes, and frogs as a cystacanth in the Americas. In this study, adults and cystacanths of M. ingens from southeastern Mexico and southern Florida, USA, were identified morphologically by having a cylindrical proboscis armed with 6 rows of hooks each with 6 hooks. Hologenophores were used to sequence the small (SSU) and large (LSU) subunits of ribosomal DNA and cytochrome c oxidase subunit 1 (cox 1) from mitochondrial DNA. Phylogenetic analysis of the new SSU and LSU sequences of M. ingens placed them in a clade with other sequences available in GenBank identified as M. ingens. The cox 1 tree showed that the nine new sequences and six previously published sequences of M. ingens from the USA form a clade with other sequences previously identified as M. ingens from GenBank. The intraspecific genetic divergence among isolates from the Americas ranged from 0 to 2%, and in combination with the phylogenetic trees confirmed that the isolates belonged to the same species. The cox 1 haplotype network inferred with 15 sequences revealed 10 haplotypes separated from each other by a few substitutions. Rio Grande Leopard Frogs and Vaillant´s Frogs harbored cystacanths with low prevalence, 28% and 37% respectively, in Mexico. Brown Basilisks, an invasive lizard in Florida, USA, had high values of prevalence, 92% and 93% in males and females, respectively. Females harbored more cystacanths than males (0-39 vs 0-21) for unknown reasons that may, however, be related to ecological differences.
