“…The total number of nuclei in the tail is 34.4±0.2 (N=10). n, nucleus; nc, nerve cord; arrow, 5HT-IR neurones, arrow head, α-tubulin-IR processes conformity with that of sensory receptors described by another authors (Stenko 1985;Kostadinova 1993;Bell et al 1997;Abdul-Salam and Sreelatha 2004). Immunostaining (IS) with anti-α-tubulin has the advantage that it can be combined with other IS techniques, thereby enabling comparisons between the sensory receptors and the general NMS.…”

The neuro-muscular system (NMS) of cercariae with different swimming patterns was studied with immunocytochemical methods and confocal scanning laser microscopy. Specimens of the continuously swimming Cercaria parvicaudata, Maritrema subdolum and Himasthla elongata were compared with specimens of the intermittently swimming Cryptocotyle lingua and the attached Podocotyle atomon. The patterns of F-actin in the musculature, 5-HT immunoreactive (-IR), FMRFamide-IR neuronal elements, α-tubulin-IR elements in the nervous and sensory systems and DAPI-stained nuclei were investigated. The general plan of the NMS was similar in all cercariae studied. No major structural differences in the patterns of muscle fibres were observed. However, in the tail of C. lingua, transverse muscle fibres connecting the bands of longitudinal muscles were found. No major structural differences in the 5-HT- or FMRFamide-IR nervous systems were observed. The number of 5-HT-IR neurones in the cercarial bodies varied between 12 and 14. The number and distribution of the α-tubulin-IR processes on the cercarial bodies and tails differed from each other. The relation between the number and structure of the α-tubulin-IR processes and the host finding strategy of the cercariae is discussed. A detailed schematic picture of the NMS in the tails of C. lingua and M. subdolum is presented.

“…The distribution of ventral sucker sensilla (4S 1 + 6S 2 = 10) recorded for most Cotylurus (Szidat 1928) and all Ichthyocotylurus spp. is not even unique to these closely related genera, also being reported by Kostadinova (1993) for the diplostomid Codonocephalus urniger (Rudolphi, 1819).…”

“…weakens that author's proposal that the main difference in cercarial chaetotaxy between the Diplostomidae and Strigeidae is the position of the lateral sensilla on the tail stem. Kostadinova (1993) noted the lack of complete chaetotaxy descriptions of strigeid cercariae and commented on the variability of lateral tail stem sensilla within this family, resulting in its unsuitability as a character for differentiation at this level. There does, however, appear to be some taxonomic value to this feature at the subgeneric/generic level, since Apatemon (Apatemon) spp.…”

Chaetotaxy and armature of Ichthyocotylurus erraticus (Rudolphi, 1809) and I. variegatus (Creplin, 1825) cercariae (Digenea, Strigeidae)

The armature and chaetotaxy of Ichthyocotylurus erraticus (Rudolphi 1809) and I. variegatus (Creplin 1825) cercariae were studied using scanning electron microscopy (SEM) and silver staining of the argentophilic sensilla. This represents the first detailed investigation of the surface structures of cercariae belonging to this genus. Both species exhibited a similar armature, although differences were recorded in the number of spines comprising the pre-oral tuft and the number of rows of spines in the post-oral collar. The number and the distribution of sensilla were found to be identical for both species of cercariae. Four types of sensilla, common to both species, were identified that differed in cilia length and in the structure of the surrounding collar. The distribution of particular sensillary forms was found to be consistent in both species.

“…Particularly in Iran, C. codonocephalus has been recorded parasitizing P. ridibundus in the northeast and in the southwest (Mashaii, 1999, 2005; Mashaii et al, 2000). The life cycle of this species involves the snail Stagnicola palustris Müller, 1774 as first intermediate host, marsh frogs as second intermediate hosts and ardeiform birds as definitive hosts (Kostadinova, 1993; Niewiadomska, 1964; Prudhoe & Bray, 1982).…”

SummaryFourty seven specimens of Pelophylax ridibundus were collected in the vicinity of Shiraz, Fars Province, Iran in 1972. Fourteen helminth species were found, eight digeneans (Diplodiscus subclavatus, Halipegus alhaussaini, Haematoloechus similis, Codonocephalus urniger, and four species of metacercariae) and 6 nematodes (Cosmocerca ornata, Rhabdias bufonis, Abbreviata sp., Eustrongylides sp., Onchocercidae gen. sp. and one species of larval nematodes). Of these, only six are adults, while 8 are in their larval stage. The most prevalent helminths were the metacercariae of Codonocephalus urniger (61.7%) and the larvae Abbreviata sp. (55.32%). The adults with the highest prevalence are the digenean Halipegus alhaussaini, and the nematode Cosmocerca ornata (34% in both cases).
