Fig. 5 in Description, molecular identification and pathological lesions of Huffmanela persica sp. nov. (Nematoda: Trichosomoididae: Huffmanelinae) from the daggertooth pike conger Muraenesox cinereus
Fig. 5 Photomicrographs from histological sections of infected tissues of a daggertooth pike conger eel. A, B Histological sections of the stomach infected by eggs of Huffmanela persica sp. nov. at various stages of development as well as degenerated encysted metazoans (⁎). C, D Sections of the tunica serosa of the stomach parasitized with completely developed eggs. E Sections of the ovarian lamellae infected by both clusters of immature (➔) and developing (➤) eggs, representing immature and previtellogenic oocytes embedded within a loose fibro-granulomatous infiltration containing histiocytes and eosinophilic granular leukocytes (⁎). F Magnified view of histological section of infected ovary showing a fibro-granulomatous infiltrate surrounding clusters of eggs at different stages of development (mainly highly developed eggs, ➤). G High magnification (100×) view of a fully developed egg of H. persica (cross-sectional view) showing larva in-folded within the eggshell and a protruding polar plug at either end. H Less developed eggs with a nearly central nucleus (⁎) and thin eggshell layer and I fully developed eggs containing twisted larvae of H. persica cut on varying planes of section
Fig. 4 in Description, molecular identification and pathological lesions of Huffmanela persica sp. nov. (Nematoda: Trichosomoididae: Huffmanelinae) from the daggertooth pike conger Muraenesox cinereus
Fig. 4 Scanning electron micrographs of poorly developed (A–D) and fully developed (E–I) eggs of Huffmanela persica sp. nov. (separated from infected ovary). Less developed eggs spherical shaped (white arrow shows a shrunken and wrinkled egg) and with no evidently developed polar plugs. Fully developed eggs oblong and containing two plugs at poles. Eggs completely surrounded by a UL bearing uniformly based mammiform mounds adorned with tendril-like vermiform appendage emerging from the apex, occasionally adjoined to that of a neighboring mound (green arrowheads). Note the illusory appearance of serrated-like ridges (occasionally in the form of illusory interconnecting ridges, black arrows) in side views which is caused by overlapping of the mound bases (well observed in less developed eggs, red arrowheads). Outer surface of eggshell with irregular protuberances (yellow arrowheads)

Fig. 3 in Description, molecular identification and pathological lesions of Huffmanela persica sp. nov. (Nematoda: Trichosomoididae: Huffmanelinae) from the daggertooth pike conger Muraenesox cinereus
Fig. 3 General morphology and surface ornamentation pattern of eggs of Huffmanela persica sp. nov. in various stages of development. A–H Photomicrographs and a–h corresponding line drawings of individual eggs at different stages of development (scale bars: 20 µm). A, a Eggs in stage I at very early stage, probably meiosis I, with a spherical nucleus in granular cytoplasm and incompletely developed chitinous layer and polar plugs (note early appearance of superficial projections of UL already apparent). B, b Eggs in stage II at later stage of development (probably meiosis II); chitin deposition appears to be complete. C, c Two-celled mitotic stage of early embryonic development (embryonated). D, d Later multicellular stage of embryonic development; chitinous layer still uniformly translucent with no apparent division into outer and inner chitinous layers. E, e Eggs in stage III with bean-like embryo and chitinous layer appearing two-layered under bright-field (light) microscopy with darker inner layer. F, f Tadpole-like embryos with UL appearing to have been partially dislodged from chitinous layer. G, g Eggs in stage IV with darker-brown shell; embryo now vermiform (larvated) and in-folded three times (pretzel stage). H, h Later stage IV egg with chitinous layer very dark brown; larva nearing final development and folded 5–6 times. I–T Photomicrographs of less developed (I–L), moderately developed (M–P) and fully developed (Q–T) eggs, where the first set of images (I, M, Q) represents overview of these variously advanced eggs, and the second (J, N, R), third (K, O, S) and fourth (L, P, T) series of images focus on the pattern of their surface ornamentation by adjusting the focal plane. Black and yellow arrows represent illusions of superficial ridges (well demonstrated in less developed eggs; occasionally appearing as interconnecting ridges, blue arrowhead) and sculptures on the egg surface, respectively. Green arrowheads exhibit irregular protuberances on the eggshell surface. Red arrowheads indicate an illusory spinous appearance in fully developed eggs
