“…Birds were collected in March 2009 and 2010 at the Hel Peninsula (54°46'N, 18°28'E) (two birds; worm range, 6–9) as well as in October and November 2008 and 2009 near Bukowo-Kopań (54°28'N, 16°25'E) (three birds; worm range, 62–220) and in the city of Szczecin (53°26′N, 14°32′E) (one bird, 132 worms). Digeneans were fixed in 70–75% ethanol, examined under a stereomicroscope and initially assigned to morphotypes using the characteristics given by Pojmańska (1969b), with a due consideration to descriptions provided by Bakke (1980, 1982).…”

Unlike the sporocyst stages, adult leucochloridiid digeneans are difficult to differentiate. Sporocyst broodsacs can be identified on the basis of their colour and banding pattern, but in the absence of broodsacs and when experimental infection cannot be performed, tentative morphological identification needs to be verified, and molecular techniques offer a tool to do this. In this study, adult leucochloridiid digeneans were collected from the great tit (Parus major) found dead at three localities at or near the Baltic Sea coast (Hel, Bukowo-Kopań and Szczecin) in northern Poland. On the basis of differences in their morphological characters, Hel specimens were tentatively assigned to Leucochloridium perturbatum, Bukowo-Kopań and Szczecin specimens being identified tentatively as L. paradoxum. Subsequent ribosomal DNA sequence analysis confirmed the identification of these leucochloridiid flukes. Nucleotide sequences discriminating between the two species were identical to those used by earlier authors as characteristic of two distinctly different sporocyst broodsacs representing L. perturbatum and L. paradoxum.

Scanning electron microscopic observations have been made on the tegument and body pores of the worm Isoparorchis hypselobagri (Billet 1898) Odhner 1927, collected from the air bladder of the freshwater fish Wal/ago attu (Schn.). The dorsal and ventral surfaces show characteristic differences under high resolution. Muscles, in hexagonal shape, are arranged on dorsal surface which give a brick floor appearance whereas the ventral surface is occupied by loose, irregular muscles. Sensory papillae are arranged in the excretory pore region around the excretory opening.Keywords. Scanning electron microscope; Isoparorchis hypselobagri; Wal/ago attu. l. IntroductionScanning and transmission electron microscopic studies are lacking on Indian trematodes except the work on Encyclometra colubrimurorum by Simha and Krishna (1979), Gastrothylax crumenifer and Paramphistomum epiclitum by Tandon and Maitra (1981), Phyllodistomum vachius by Pandey and Tewari (1982) and Bucephalopsis karvei by Pandey and Tewari (1984). However, few references on SEM and TEM studies on adult trematodes Diplostomum phoxini by Erasmus (1970), Schistosoma monsoni by Silk et al (1970), Magalodiscus temperatus by Nollen and Nadakavukaren (1974), Fasciola hepatica by Bennett (l975a, b), Leucochloridium sp. and Urogonimus macrostomum by Bakke (l976a, b, 1978), Schistosoma haematobium by Kuntz et al (1976), Schistosoma japonicum by Sakamoto and Ischii (1977), Schistosoma matthei by Tullock et al (1977), Phyllodistomum conostomum by Bakke and Lien (1978) and Clonorchis sinensis by Fujino et al (1979) are available. Currently SEM has been employed by helminthologists to study the surface topography or surface features and other characters of helminth parasites to understand the structural adaptation in different micro-environment. In the present study the observations on surface topography of Isoparorchis hypselobagri (Billet 1898) Odhner 1927, an air bladder parasite of freshwater fish Wallago attu are reported. Materials and methodsSpecimens of I. hypselobagri were collected from the air bladder of the freshwater fish W. attu, rinsed in 1% saline and fixed in 4% gluteraldehyde prepared in phosphate buffer of pH 6·8. They were dehydrated in graded alcohol series followed by treatment in amyl acetate and then dried by critical point drying using a 373
