Fig. 2. Intra- and extracellular forms of APXSc within the Tehuelche scallop. (A–B) H&E stained section (A) and ISH (B) showing APXSc forms within the stomach epithelium (Ep), suggestion that infections are via the gastrointestinal tract. (C–D) H&E stained section (C) and ISH (D) showing APXSc in the connective tissue adjacent to the gastrointestinal tract. Many of the parasite forms are found inside hemocytes with the host nuclei marginalized (white arrowheads) whilst other forms are still free (black arrowheads) in the connective tissue. Sl = Stomach lumen; Ct = connective tissue; Bm = basement membrane.

Fig. 9 in A phylogenetically unresolved apicomplexan (APXSc) causing swirl lesions in the Tehuelche scallop, Aequipecten tehuelchus, from the Southwest Atlantic coast

Fig. 9. Maximum likelihood topology from phylogenetic analysis of the SSU rDNA of the main clades of apicomplexans and the basal Chrompodellids, using the dinoflagellates as an outgroup. Numbers at the nodes denote bootstrap support values (1000 replications) with the scale shown at the bottom of the tree. The sequence generated in this study is shown in bold and groups together with a parasite known to infect oysters in New Zealand. This novel clade does not show any phylogenetic affinity to the known clades of apicomplexans infecting marine and terrestrial animals and is placed at the base of the tree next to the Chrompodellids.
