| [helminth parasites of white bream (blicca bjoerkna l. 1758) from kocadere stream, bursa.] | aim of this study was to investigate the helminths and their monthly prevalence in 120 blicca bjoerkna (white bream) in the kocadere stream (bursa province) from february 2005 to january 2006. as a result, 98.3% of b. bjoerkna were found to be infected with one or more helminth species and a total of 5 different helminth species were identified. the distribution of these parasites in b. bjoerkna and the average prevalence (annually) were as follows: dactylogyrus sphyrna (24.2%), d. distinguendus ... | 2010 | 20597058 |

| levels of infection of gastric nematodes in a flock of great cormorants ( phalacrocorax carbo) from lake biwa, japan. | a high prevalence (86.7%) of various species of nematodes was observed in the stomach of great cormorants living in lake biwa, japan. there were varying numbers of adults belonging to two common genera, eustrongylides jagerskiold 1909 (nematoda: dioctophymatidae) and contracaecum railliet & henry 1912 (nematoda: anisakidae). the first included common adenophorean nematodes comprising a single species, eustrongylides tubifex and the second comprised ascaroid nematodes that contained four named sp ... | 2011 | 21342602 |
| the colonization of the invasive round goby neogobius melanostomus by parasites in new localities in the southwestern baltic sea. | the round goby neogobius melanostomus is a bottom-dwelling fish native for the ponto-caspian basin, which started to colonize the baltic sea since 1991. the parasites of this fish species in the southwestern baltic region are studied for the first time. the round goby in the sw baltic sea was infected with 12 parasite species: 1 species of microsporidia, 1 species of monogenea, 1 of cestoda, 3 species of trematoda, 3 species of nematoda, 2 of acanthocephala, and 1 species of bivalvia. microspori ... | 2011 | 21409440 |
| helminth parasitism in the neotropical cormorant, phalacrocorax brasilianus, in southern brazil: effect of host size, weight, sex, and maturity state. | forty-seven specimens of neotropical cormorants, phalacrocorax brasilianus, from lago guaíba, guaíba, state of rio grande do sul, brazil (30° 00' s, 51°15' w), were examined for helminth parasites between 1999 and 2003. twenty species of helminth parasites were found: ten digeneans: austrodiplostomum mordax, austrodiplostomum compactum, clinostomum sp., drepanocephalus olivaceus, drepanocephalus spathans, hysteromorpha triloba, ignavia olivacei, paryphostomum segregatum, prosthogonimus ovatus, a ... | 2011 | 21431903 |
| the helminth community of the sand smelt (atherina boyeri risso, 1810) from lake iznik, turkey. | metazoan parasites of the sand smelt atherina boyeri risso, 1810 in lake iznik were studied. a total of 271 specimens of a. boyeri, 208 female and 63 male, mean ( ± sd) total length 8.4 ± 2.2 cm (range 3.1-12.2 cm) and mean total weight 4.7 ± 3.5 g (range 0.1-11.7 g) were examined between june 2008 and may 2009 at monthly intervals. in 33 fish no parasites were found. in the other fish, four parasite species were recorded: diplostomum sp. (prevalence 39.13%, mean intensity 3.50 ± 3.03); tylodelp ... | 2011 | 22189412 |
