Summary Of the 105 great cormorants (Phalacrocorax carbo sinensins) from northern Poland (the Vistula Lagoon and Masurian Lake District), examined in 2000–2001, 67 proved hosts of the nematode
Syncuaria squamata (Linstow, 1883). The prevalence, mean intensity, and intensity range amounted to 63.8 %, 36.2 specimens, and 1–120 specimens,
respectively. The infection was heavier in the immature birds (84.6 %, 40.9 inds, and 1–120 inds) than in the adults (3.7
%, 1 ind.). The nematodes were dominated by gravid females (n=1846), followed by males (n=157), immature females (n=79), and
L4 larvae (n=2). Measurements of the parasite are provided. S. squamata is a new species for the parasite fauna of Poland. 相似文献

Gongylonema neoplasticum was identified in the oesophagus of 14 wild rabbits (Oryctolagus cuniculus) from Portugal. This is the first record of Gongylonema neoplasticum in a naturally infected lagomorph species in Europe. This paper presents the most relevant measurements of adult worms and
some of their surface features seen by scanning electron microscopy. Epidemiological aspects of G. neoplasticum such as geographical distribution, host spectrum and biological features are discussed. 相似文献

Summary Light and scanning electron microscopical examination and molecular analysis of pinworm samples collected from the Sumatran
orangutan (Pongo abelii) from Sumatra (Indonesia) revealed the presence of a new taxon, Pongobius hugoti gen. et sp. n. (Oxyuridae: Enterobiinae). The monotypic genus Pongobius is characterised by the presence of a triangular mouth, three rounded teeth and three chisel-like inner teeth in the buccal
cavity, an oesophagus with a long pharyngeal part, corpus posteriorly slightly enlarged and continuing as a pyriform bulb,
isthmus absent. These features differentiate P. hugoti from all members of the subfamily Enterobiinae. The male has a long caudal appendix (> 50% of total tail length). Molecular
analysis of the new taxon is presented for more precise identification. 相似文献

Three male specimens of the eyeworm, Oxyspirura chabaudi, were found during the post mortem examination of one individual of Turdus merula L. (Passeriformes). This is the first record of Turdus merula as a host for O. chabaudi. 相似文献

Falcaustra papuensis sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Sphenomorphus simus (Squamata, Sciencidae) is described and illustrated. Falcaustra papuensis represents the 4th Australo-Papuan species assigned to this genus and is distinguished from other Australo-Papuan species
by the distribution pattern of caudal papillae (6 precloacal, 6 adcloacal, 8 postcloacal, and 1 median), length of spicules
(561–714 μm) and presence of a pseudosucker. Sphenomorphus simus was found to harbor 2 additional species of nematodes, Meteterakis crombiei and Oswaldocruzia bakeri. Sphenomorphus simus represents a new host record for each of these nematode species. 相似文献

Aplectana krausi sp. nov. (Ascaridida, Cosmocercidae) from the intestines of Platymantis boulengeri (Anura, Ceratobatrachidae) is described and illustrated. Aplectana krausi represents the 42nd species assigned to the genus, the 4th species reported from the Australo-Papuan region. It is easily
separated from the three species previously reported from the region by the distribution pattern of male caudal papillae:
A. macintoshii and A. novaezelandiae have irregular patterns; A. zweifeli and A. krausi have defined patterns. Aplectana zweifeli has 8–10 precloacal, no adcloacal, and 9 postcloacal pairs of papillae, there is a single median papillae just anterior to
the cloaca; A. krausi has 5 precloacal, 1 adcloacal, and 5 postcloacal pairs of papillae, a median papillae is absent. 相似文献

Anisakid nematodes parasitize mainly fish, marine mammals and/or fish-eating birds, and can be transmitted to a range of fish-eating mammals, including humans, where they can cause gastrointestinal disease linked to larval infection or allergic responses. In spite of the animal and human health significance of these parasites, there are still gaps in our understanding of the systematics, biology, epidemiology and ecology of anisakids. Mitochondrial (mt) DNA provides useful genetic markers for investigations in these areas, but complete mt genomic data have been lacking for most anisakids. In the present study, the mt genomes of Anisakis simplex sensu stricto and Contracaecum osculatum sensu stricto were amplified from genomic DNA by long-range polymerase chain reaction and sequenced using 454 technology. The circular mt genomes of these species were 13,926 and 13,823 bp, respectively, and each of them contained 12 protein-coding, 22 transfer RNA, and 2 ribosomal RNA genes consistent for members of the Ascaridida, Oxyurida, Spirurida, Rhabditida and Strongylida. These mt genomes provide a stepping-stone for future comparative analyses of a range of anisakids and a basis for reinvestigating their genetic relationships. In addition, these markers might be used in prospecting for cryptic species and exploring host affiliations. 相似文献

Tortoises of the genus Testudo living in Italy are Testudo hermanni, Testudo graeca and Testudo marginata. Although a great deal of information has been acquired on the internal medicine and surgery on these animals, little is known of their parasitological fauna. A survey on the presence of gastro-intestinal parasitic nematodes in tortoises bred in Italy was carried out to acquire extensive epidemiological data. Stool samples of 62 tortoises (37 T. hermanni hermanni, 13 T. graeca, 6 T. hermanni boettgeri and 6 T. marginata) were macroscopically examined and subjected to qualitative (flotation and Baermann techniques) and quantitative (McMaster technique) microscopic examinations. Adult nematodes were identified using morphological keys. Eggs of oxyurids (species indistinguishable) and adults of Alaeuris numidica, Mehdiella microstoma, Mehdiella uncinata, Tachygonetria longicollis, Tachygonetria conica and Tachygonetria palearcticus (Oxyurida, Pharyngodonidae); larvae and adults of Atractis dactyluris (Ascaridida, Atractidae); and eggs and adults of Angusticaecum holopterum (Ascaridida, Ascarididae) were identified in all animals >1 year, whereas all tortoises <1 year of age were parasite-free. Moreover, this study reports for the first time A. numidica and M. microstoma in T. marginata. This work shows that nematodes affecting tortoises are diffused in Italy and highlights the need to investigate their epidemiology more in depth. 相似文献

A West African species of gecko, Tarentola parvicarinata Joger (Gekkonidae), collected in the Niokolo Koba National Park in East Senegal is a new host species for the nematode Parapharyngodon echinatus (Rudolphi, 1819). Fifty one specimens of P. echinatus were studied under a light microscope and thirteen specimens were studied for the first time by a scanning electron microscope.
The main differences between P. echinatus and other African species, especially Parapharyngodon micipsae (Seurat, 1917), were in the shape of annules on body cuticle, broad lateral alae and their terminations, the shape of the
distal extremity of the spicule and number of outgrowths at the anterior cloacal lip. For the purposes of DNA characterization,
partial sequence of the small subunit ribosomal RNA gene (SSU rRNA) was obtained from two specimens of P. echinatus. This is the first published sequence of a species from the family Pharyngodonidae. 相似文献

Summary The study was aimed at following, under laboratory conditions, embryogenesis of the nematode Contracaecum rudolphii, and at identifying its intermediate hosts in northeastern Poland. Nematode eggs, isolated from the terminal part of the
female uterus, were placed in 0.9 and 3% NaCl solutions, 1% formalin, and in tap water. Each solution batch was divided into
3 parts kept at 4, 15, and 23°C. Regardless of the temperature they were exposed to, the eggs placed in 1% formalin showed
numerous deformations; as few as 5% of those eggs produced larvae. Embryogenesis was at its fastest in the eggs kept at 23°C.
While still within the eggs, the larvae underwent two moults. The eggs hatched to produce the stage 3 larvae, which emerged
surrounded by the cuticle of the preceding larval stage. Experimental infestations of zooplankton collected from Lake Kortowskie
showed that only cyclopoid copepods could serve as the intermediate hosts. No differences in the infestation intensity were
found between the guppies infested by the invasive larvae and those fed the infested cyclopoids. 相似文献
