Fig. 2 in Description of Babesia coryicola sp. nov. from Florida pumas (Puma concolor coryi) from southern Florida, USA
Fig. 2. Genetic relationships of Babesia coryicola sp. nov. from Florida pumas (Puma concolor coryi) compared with other Babesia spp. based on near full length 18S rRNA gene sequences. The text in bold blue in the figure represents specimens analyzed in this study. Sequences in light blue are species that have been primarily associated with felid hosts. Green lineages are predominately associated with canid hosts but have been reported in felids. Several sequences derived from domestic cats (i.e., MW578972, PP151898, and PP151899) and wild felids (i.e., HQ187782 and HQ187782) were not included in the analysis because the sequences were short.

Fig. 5 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 5. Maximum Likelihood (ML) phylogenetic reconstruction of the mitochondrial Cytochrome C oxidase Subunit I (cox1) gene tree of the Sarcocystis spp. under investigation. Where possible, sequences of the same species were used as shown in the 18S rRNA gene tree, including the outgroup. The newly sequenced Sarcocystis spp. are marked with black symbols. A total of 25 nucleotide sequences and 603 sites of the barcode area (all codon positions included) was analyzed with 1000 bootstrap replicates. Branch support from three replicate analyses is shown. The evolutionary history was inferred by using ML based on the HKY model. The tree with the highest log likelihood (– 6438.6551) is shown. A discrete Gamma distribution was used to model evolutionary rate differences among sites (four categories [+G, parameter = 0.9037]). The rate variation model allowed for some sites to be evolutionarily invariable ([+I], 17.4959% sites). All positions with less than 98% site coverage were eliminated. Branch lengths are measured in the number of substitutions per site. Note the long branch lengths of ruminant Sarcocytis spp. in comparison to other members of the Sarcocystidae as well as eimeriid coccidia from phylogenetically diverse hosts.
Fig. 2 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 2. Ultrastructure of Sarcocystis sp.1 from the mangrove snake in abdominal musculature of a Sprague-Dawley rat; a) One μm-thin section through a resin-embedded, toluidine-stained sarcocyst showing densely-packed cystozoites (CZ) that were contained in septate compartments; the arrow indicates the cyst wall with small protrusions, which are clearly visible because host cell (HC) tissue is removed at this position; b) gross view of the cyst wall and cystozoites in a longitudinal section; the black arrow indicates a thin septum that separated the compartments filled with cystozoites; protrusions (PT) were broad, short, and irregularshaped, often with a reticulate base that rested on a thin layer of ground substance (GS); c) cross-section of sarcocyst, showing the primary cyst wall at higher magnification to consist of electron-dense, knob-like structures with intermittent invaginations; it appeared as if the primary wall was fenestrated (asterisk) allowing exchange of fine granular material (arrowheads) between the interior and exterior of the cyst; the exterior space between the protrusions was entirely filled with granular substance. d) metrocytes exclusively divided by endodyogeny as only cells with two developing zoites (asterisks) were observed; the white arrow points at deposits of highly electron-dense matter that could form larger clusters in the GS of the septae.
Fig. 1 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 1. Light microscopic observations on the development of Sarcocystis sp.1 in striated musculature of Sprague-Dawley rats; a) typical sporocysts, here in fecal smear from Boiga dendrophila, that were used for infection of rats; sporocysts contained a granular residual body (asterisk) and four sporozoites (SP), which are all visible in the upper sporocyst; b) full-length micrograph of a typical (native) sarcocyst of Sarcocystis sp.1 in striated belly musculature, the arrows indicating folds of the cysts' body; c) high magnification of the cyst wall of a native sarcocyst, the arrows pointing at the apparently smooth wall; this is the same cyst as depicted in Fig. 2a; the inset shows freshly released, live cystozoites under phase-contrast light microscopy.
Fig. 4 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 4. Predicted secondary structure of helix 38 in domain V7 of the 18S rRNA of Sarcocystis sp.1, Sarcocystis sp.2, S. attenuati, S. scandentiborneensis, and S. zuoi in comparison to S. clethrionomyelaphis (shaded inset). The 7-nt long motif 5′-AAUUCGU-3' (relative to all Apicomplexan taxa examined; nt in italic letters in shaded oval) mapped to a hairpin loop position of helix 38 and was characteristic for all species of the S. zuoi – complex; the motif was one nt (Cytosine) shorter in helix 38 of S. clethrionomyelaphis. Sequences were aligned to a secondary structure model of the Eukarya using SSU-ALIGN. The numbering of nucleotides (bars) and helices is based on the 1881 nt-long structural template. Position 1430 corresponds to position 1357 of the predicted secondary structure of Toxoplasma gondii (RH strain) as published by Gagnon et al. (1996).
Fig. 3 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 3. Bayesian Inference (BI) of the 18S rRNA phylogeny of Sarcocystis spp. infecting colubrid snakes and small mammals in Asia; the S. zuoi – complex of species is highlighted by the shaded box. This complex excludes S. clethrionomyelaphis, which branches off basally. All new sequences, including a new isolate of S. zamani from Sumatra, are highlighted by black symbols. The known definitive and/or intermediate hosts associated with the selected sequences of the S. zuoi-group are indicated. Eimeriid species from phylogenetically diverse hosts served as outgroups. Bayesian posterior probabilities of three independent analyses (and alignments) are indicated behind each node, showing only one value if results of replicates were identical.
Fig. 6 in Morphological and molecular phylogenetic characterization of Sarcocystis kani sp. nov. and other novel, closely related Sarcocystis spp. infecting small mammals and colubrid snakes in Asia
Fig. 6. Mapping of (A) potential heme ligand binding sites and (B) amino acid variability among different lineages of tissue cyst-forming coccidia in the barcode area of the mitochondrial COX1 protein. A) Map of putative heme ligand binding sites (arrowheads) in a protein sequence alignment of selected taxa used in the phylogenetic tree of cox1. Identical/conservative aa positions are highlighted by light background, variable positions and gaps are shown against black background. Helix 1 (H1) is shown partial, starting at position 14 of the global barcode alignment (Pentinsaari et al., 2016); aa sequences of helices 2 (H2) and 6 (H6) are shown in full length, while putative heme binding sites of loop 3–4 (L3-4) were in its anterior part only. Domain boundaries and putative ligand binding sites were derived from COX1 of template organisms Saccharomyces cerevisiae and Bos taurus by sequence alignment against Toxoplasma gondii applying three-dimensional homology modelling of protein structure. The complete alignment of the six helices of the barcode area is shown in Supplementary Fig. S2. Note that aa numbering of the barcode area of the Apicomplexan sequence is different to the global alignment, because the former showed one additional aa and domain boundaries were slightly altered. The nucleotide sequence KC209732 of S. tenella (GenBank) is also registered in the barcode reference database BOLD (accession number JRPAA5858-15; http://boldsystems.org); the aa barcode position 14 (Glycine) shown here corresponds to position 16 of the aa translation of GenBank record KC209732. B) 'Heat map' of aa changes (darker shades of green = more changes, number of changes indicated) in the barcode area among chemically/structurally different aa groups in different lineages of tissue cyst-forming coccidia relative to the COX1 protein sequence of T. gondii. Because helix 1 was truncated, records of aa changes in this area are incomplete.
