Principal intestinal parasites of dogs in Tirana, Albania.

From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae. The heart and pulmonary arteries of 30 dogs >6 months of age also were examined for nematode parasites. The intestinal parasite fauna of the dogs included three protozoan species (Cystoisospora canis, Cystoisospora ohioensis/burrowsi, Sarcocystis spp.), three cestode species (Dipylidium caninum, Taenia hydatigena, Echinococcus granulosus), five nematode species (Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis) and one acanthocephalan (Centrorhynchus buteonis). Rates of infection were: 15.3% for C. canis, 31.5% for C. ohioensis/burrowsi, 1.8% for Sarcocystis spp., 65.8% for D. caninum, 16.2% for T. hydatigena, 2.7% for E. granulosus (genotype G1), 13.5% for A. caninum, 64.9% for U. stenocephala, 75.7% for T. canis, 0.9% for T. leonina, 21.6% for T. vulpis and 0.9% for C. buteonis. Up to six species of gastrointestinal parasites were found per dog. The 63 ≤ 6-month-old dogs harboured significantly (p<0.001) fewer gastrointestinal parasite species concurrently (mean 2.65 ± 1.25 species per animal) than the 48 older animals (mean 3.77 ± 1.45 species per animal). Dogs >6 months of age harboured significantly (p<0.05) more D. caninum, T. hydatigena, A. caninum, U. stenocephala and T. vulpis compared to younger dogs. Conversely, the younger dogs harboured significantly (p<0.001) more T. canis than the older ones. There was no difference in the male and female dogs' counts of individual intestinal helminth species apart from T. hydatigena in dogs >6 months of age: Male dogs harboured significantly (p<0.05) more tapeworms than female dogs. Based on faecal examination, there was no indication for lungworm infection; however, two adult heartworms (Dirofilaria immitis) were found in the right ventricle of one dog.

Fauna europaea: helminths (animal parasitic).

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. Helminths parasitic in animals represent a large assemblage of worms, representing three phyla, with more than 200 families and almost 4,000 species of parasites from all major vertebrate and many invertebrate groups. A general introduction is given for each of the major groups of parasitic worms, i.e. the Acanthocephala, Monogenea, Trematoda (Aspidogastrea and Digenea), Cestoda and Nematoda. Basic information for each group includes its size, host-range, distribution, morphological features, life-cycle, classification, identification and recent key-works. Tabulations include a complete list of families dealt with, the number of species in each and the name of the specialist responsible for data acquisition, a list of additional specialists who helped with particular groups, and a list of higher taxa dealt with down to the family level. A compilation of useful references is appended.

Some species of Centrorhynchus Lühe, 1911 (Acanthocephala: Centrorhynchidae) from the collection of the Natural History Museum, London.

Seven species of Centrorhynchus Lühe, 1911 are present in the Parasitic Worms Collection of The Natural History Museum, London: C. aluconis (Müller, 1780) Lühe, 1911 from Strix aluco Linnaeus in Great Britain; C. buteonis (Schrank, 1788) Kostylev, 1914 from Accipiter virgatus (Temminck) (new host record) in Sri Lanka (new geographical record); C. clitorideus (Meyer, 1931) Golvan, 1956 from Athene brama (Temminck) (new host record) in India; C. crotophagicola Schmidt and Neiland, 1966 (encysted juveniles in the stomach wall) from Anolis lineatopus Grey (new host record) and A. sagrei Duméril and Bibron (new host record) from Jamaica (new geographical record); C. falconis (Johnston and Best, 1943) Golvan, 1956 from Spilornis cheela (Latham) in Sri Lanka (new geographical record); C. globocaudatus (Zeder, 1800) Lühe, 1911 from Falco ardosiaceus Vieillot (new host record) in West Africa; and C. milvus Ward, 1956 from Milvus migrans (Boddaert) in India. The species are described and figured on the basis of this material.
