Roznorodnosc biologiczna kapilarii

In Capillaria pterophylli two large pseudocoelomocytes, localised at the end of the stichosome, are embedded in an extracellular matrix of connective tissue elements. The cytoplasm contains abundant cisternae of rough endoplasmic reticulum filled with amorphous material, Golgi complexes with electron-dense material, vesicles, and few mitochondria. At the periphery, among the cytoplasmic processes, there are more or less waved lamella-like connective tissue fibres. The possibility, that these fibres are of elastin type, is discussed.
A new nematode, Paracapillaroides agonostomi gen. et sp. n., is described from the stomach and the intestine of the mugilid Agonostomus monticola (Bancroft) from the Cuitzmala River (the Pacific Ocean basin), State of Jalisco, Mexico. This capillariid species represents a new genus similar to Paracapillaria Mendonça, 1963, differing from it substantially in the structure of the spicular sheath that is formed by two distinct parts, a broader and much shorter spinose proximal part and a narrower, very long aspinose distal part. Another capillariid, Paracapillaria teixeirafreitasi pacifica subsp. n. is described from the intestine of eleotrids Gobiomorus polylepis Ginsburg (type host) and G. maculatus (Günther) from the same locality (Cuitzmala River, Jalisco). This subspecies is differentiated from P. teixeirafreitasi teixeirafreitasi (G. Caballero, 1971) by the absence of a pair of minute preanal papillae, by a considerably longer spicule (0.261-0.501 mm), a distinctly thicker egg wall, and by the geographical distribution (Pacific Ocean basin). P. teixeirafreitasi teixeirafreitasi is briefly described from specimens collected from Gobiomorus dormitor Lacépède from the Tecolutla River, Veracruz, Mexico.
This paper contains the second record and locality of S. petruschewskii in Poland. This nematode was found on the catfish (Ictalurus nebulosus L.) from the Odra River in Wrocław (Lower Silesia). S. petruschewskii have been described only in Gymnocephalus cemuus from the Szczecin Firth until now. The authors gave the illustrations (with dimensions) of this species, according to the material from the catfish.
A redescription of a nematodes Capillaria carbonis was made on the basis of specimens found for the first time in Phalacrocorax carbo in Poland in Milicz district. It has been found that: the body of male terminates with two processes with a single large papilla, in its distal part surrounded by cuticular pseudobursa formed from four cuticular lobes; spicular sheath nonspiny has a transverely-oblique striation; two lateral bacillary bands extend along whole body; number of stichocytes equals 38-42 and 42-45 in males and females respectively; vulva of gravid females appears sometimes with vulvar appendage.
Biometrical analysis of four morphometric characters of male and female specimens of Capillaria ovopunctata parasitizing in Sturnus vulgaris, Erithacus rubecula, Turdus philomelos and Turdus merula, i.e. length of body, oesophagus, number of stichocytes or length of spicula and vulvar appendage respectively was carried out. It has been proved, that characters of females C. ovopunctata parasitizing in T. merula significantly differ from those of the nematodes found in other hosts. The present and previous author's results on high extensiveness and intensity of invasion allow to state that T. merula is a proper host for C. ovopunctata.
A new nematode species, Capillostrongyloides norvegica sp. n., is described from the stomach of the lotid marine fish Enchelyopus cimbrius (Linnaeus) (Lotidae, Gadiformes) from the coastal waters near Bergen, Norway. This is characterized mainly by its body size (body length of male and female 4.01-5.74 and 7.83-12.28 mm, respectively), number (32-41) and structure of the stichocytes, length of the spicule (0.273-0.366 mm), structure of the male caudal bursa (markedly large caudal membrane), structure and size of the eggs (size 0.063-0.075 x 0.027-0.033 mm), and by the presence of the conspicuously elevated anterior vulvar lip in females. This is the first Capillostrongyloides species reported from fishes in Europe. A key to Capillostrongyloides species is provided. Another capillariid, Capillaria gracilis (Bellingham, 1840), occurred in the rectum of E. cimbrius of the same locality (a new host record).
Examinations of materials of trichinelloid nematodes recently collected from the digestive tract of marine fishes off New Caledonia, South Pacific, revealed the presence of several species of the families Capillariidae and Trichosomoididae, including capillariids Pseudocapillaria novaecaledoniensis sp. nov. from the deep-sea Pristipomoides argyrogrammicus (Valenciennes) (Lutjanidae) and Pseudocapillaria echenei (Parukhin, 1967) from Echeneis naucrates Linnaeus (Echeneidae), and the trichosomoidid Huffmanela sp. (female) from Bodianus perditio (Quoy et Gaimard) (Labridae). P. novaecaledoniensis is characterized mainly by the structure and length (318–321 µm) of spicule and the presence of a dorsal cuticular membrane interconnecting both ventrolateral caudal lobes in the male (subgenus Ichthyocapillaria Moravec, 1982). The previously poorly known P. echenei is redescribed and recorded for the first time from the South Pacific Ocean. In addition, five morphologically different types of capillariid females without generic identification, designated as Capillariidae gen. spp. 1–5, each of them probably representing a new species, were recorded from Fistularia commersonii Rüppell (Fistulariidae), Synodus dermatogenys Fowler (Synodontidae), Carangoides oblongus (Cuvier) (Carangidae), Diagramma pictum (Thunberg) (Haemulidae) and Stegostoma fasciatum (Hermann) (Stegostomidae), respectively. Capillaria decapteri is transferred to Pseudocapillaria Mendonça, 1963 as P. decapteri (Luo, 2001) comb. nov.
