| [life cycle of clinostomum golvani n. sp. (trematoda : clinostomidae) a larval parasite of biomphalaria glabrata, the snail vector of schistosoma mansoni in guadeloupe (author's transl)]. | the life cycle of a new species of clinostomidae, clinostomum golvani, described in guadeloupe (french west indies). the first intermediate host is the snail vector of schistosoma mansoni in this island, biomphalaria glabrata, which can be sterilized by this parasite. poecilia reticulata (guppy) serves as the second intermediate host. adult worms were obtained under experimental conditions from butorides virescens (the definitive host in nature), nycticorax nycticorax and ardea purpurea. the adu ... | 1980 | 7224533 |
| accumulation profiles of persistent organochlorines in liver and fat tissues of various waterbird species from greece. | waterbirds are particularly subject to accumulation of persistent organic pollutants (pops) that have been shown to constitute a major hazard for this group of birds. liver and fat tissue from ten species belonging to the orders ciconiformes (ardeidae, ciconiidae, phoenicopteridae) and pelicaniformes (pelecanidae, phalacrocoracidae) were used as bioindicators in order to assess environmental pollution by pops (hchs, ddts, cyclodienes, pcbs) in greek wetlands. to our knowledge, this is the first ... | 2006 | 16289289 |
| the component helminth community in six sympatric species of ardeidae. | we studied the helminth communities in 6 sympatric species of ardeidae (ixobrychus minutus (linnaeus, 1766), nycticorax nycticorax (linnaeus, 1758), bubulcus ibis (linnaeus, 1758), egretta garzetta (linnaeus, 1766), ardea cinerea (linnaeus, 1758), and ardea purpurea (linnaeus, 1766)) from "la albufera de valencia," spain. the survey revealed 13 species of helminth parasites: 5 digeneans, 2 cestodes, and 6 nematodes. the component helminth communities of the ardeidae examined are depauperate and ... | 2005 | 17089743 |
| [serological monitoring of arbovirus infections in the estuary of the kuban river (the 2006-2007 data)]. | solid-phase enzyme immunoassay, neutralization test, and the hemagglutination-inhibition test were used to study the sera from human beings (152 samples), agricultural animals (n = 77), hares (n = 3), and wild birds (n = 69), collected in 2006-2007 in the kuban river estuary (temryuk district, krasnodar territory). there were specific antibodies against viruses of west nile (wh), tick-borne encephalitis (tbe) (flaviviridae, flavivirus), sindbis (togaviridae, alphavirus), the antigenic complex of ... | 2008 | 18756814 |
| pathogenicity of clinostomum complanatum (digenea: clinostomidae) in piscivorous birds. | the present study is focused on the pathogenicity of a parasitic digenea, clinostomum complanatum among dead piscivorous birds, collected after mass mortalities in northern iran. a total of 126 birds (15 species) were examined for parasitic infections. birds of four species belong to the family ardeidae were found to be infected with immature and mature worms. c. complanatum was more prevalent in ardea purpurea followed by nycticorax nycticorax, egretta alba and egretta garzetta. pathological st ... | 2013 | 23876333 |
| porrocaecum parvum n. sp. and p. reticulatum (linstow, 1899) (nematoda: ascaridoidea) from birds in china. | porrocaecum parvum n. sp. is described from the grey-faced buzzard butastur indicus (gmelin) (accipitriformes: accipitridae) in china. the new species differs from its congeners in having well-developed cervical alae, small interlabia and very short intestinal caecum (0.34 mm long, representing 11.9% of oesophageal length) and in the number and arrangement of the caudal papillae (29 pairs in total, arranged as follows: 21 pairs precloacal, single double pair paracloacal and seven pairs postcloac ... | 2015 | 26358073 |
| organochlorine compounds in purple heron eggs (ardea purpurea) nesting in sites located around a chlor-alkali plant (ebro river). | eggs of purple heron (ardea purpurea) were collected from three sampled sites inside the ebro river basin in years 2006 and 2007. these sites were located besides (flix), upstream (aiguabarreig) and downstream (delta) a chlor-alkali plant. organochlorine compounds (ocs) such as dichlorodiphenyltrichloroethanes (ddts), polychlorobiphenyls (pcbs), polychlorostyrenes (pcss), hexachlorobenzene (hcb), pentachlorobenzene (pecb) and hexachlorocyclohexanes (hchs) were analysed to assess what are the acc ... | 2016 | 26202210 |
| chewing lice (phthiraptera) of several species of wild birds in iran, with new records. | although there are about 520 species of birds in iran, but only some of them have been checked for ectoparasites so far.the aim of this study was to check some more available species of the birds of iran for lice. | 2013 | 23785698 |
| are the toxic sediments deposited at flix reservoir affecting the ebro river biota? purple heron eggs and nestlings as indicators. | the flix reservoir, in the low course of the ebro river, contains thousands of tons of polluted sediments, accumulated from the activities of a chemical factory. an ongoing project is working toward removing these pollutants. piscivore birds like the purple heron (ardea purpurea) may be useful bioindicators, so eggs and nestling feathers were sampled during the 2006-2008 breeding seasons at three localities: a reference site situated upstream and two potentially affected by the toxic muds; one a ... | 2012 | 22526922 |
| blood biomarkers and contaminant levels in feathers and eggs to assess environmental hazards in heron nestlings from impacted sites in ebro basin (ne spain). | blood biomarkers and levels of major pollutants in eggs and feathers were used to determine pollution effects in nestlings of the purple heron ardea purpurea and the little egret egretta garzetta, sampled on three ebro river (ne spain) areas: a reference site, a site affected by the effluents of a chlor-alkali industry and the river delta. the two impacted heron populations showed mutually different pollutant and response patterns, suggesting different sources of contamination. in the population ... | 2010 | 19892448 |
| analysis of micronucleated erythrocytes in heron nestlings from reference and impacted sites in the ebro basin (n.e. spain). | the frequency of micronuclei (mn) in peripheral erythrocytes was tested for 59 heron nestlings (ardea purpurea, egretta garzetta and bubulcus ibis) sampled at two areas (polluted and reference) on the river ebro (ne spain) and at its delta during spring 2006. flow-cytometry analysis revealed higher (three- to six-fold) mn counts in samples from the most polluted site relative to samples from the reference area. samples from the delta showed intermediate values. age, morphometric parameters (weig ... | 2008 | 18063255 |
