En junio de 2012, a raíz de un fenómeno marino que produjo mortandad de varias especies de aves marinas, se estudiaron los endoparásitos en dos pelícanos (Pelecanus thagus) y dos pingüinos (Spheniscus humboldti) hallados muertos en la playa del distrito de Chorrillos, Lima-Perú. Se realizó la obtención de helmintos del tracto digestivo en ambas especies aplicando el método de Travassos. Fueron identificados en Pelecanus thagus los nematodos Contracaecum rudolphii y Syngamus trachea, el cestodo Tetrabothrius sp, el trematodo Galactosomum puffini y el acantocéfalo Corynosoma sp. En Spheniscus humboldti, el trematodo Cardiocephaloides physalis y los nematodos Contracaecum pelagicum y Cyathostoma phenisci. Syngamus trachea, Galactosomum puffini, Corynosoma sp y Contracaecum pelagicum son considerados nuevos reportes en Pelecanus thagus en el Perú. Además, Spheniscus humboldti puede ser considerado nuevo hospedero de Cardiocephaloides physalis y Cyathostoma phenisci.

AbstractThe availability of aquatic insects (Odonata: Coenagrionidae, Libellulidae and Trichoptera: Integripalpia) as potential intermediate hosts for the nematode Contracaecum rudolphii Hartwich, 1964 sensu lato was studied under laboratory conditions. The infective material consisted of nematode eggs, newly hatched larvae, as well as in vitro infected cyclopoid copepods. High prevalence and intensity of infection associated with a low mortality of aquatic insect larvae suggests that they may serve as intermediate hosts for C. rudolphii and constitute a major reservoir of C. rudolphii larvae in aquatic habitats.

Great Cormorants

AbstractA 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 species: Contracaecum rudolphii Hartwich, 1964, Contracaecum microcephalum Yamaguti, 1961, Contracaecum multipapillatum Drasche, 1882 and Contracaecum chubutensis Garbin, 2008. After the prevalence and intensity of the infection had been noted, both types of nematodes were frequently observed to penetrate the mucosa and intrude into the wall of the glandular stomach, where they caused gross haemorrhage and ulceration. The Eustrongylides sp. was predominantly found in a nodular lesion of the proventricular wall, while Contracaecum spp. were observed either free in the lumen of the proventriculus or, on occasion, deeply penetrating its wall. Of the Contracaecum spp., C. rudolphii was the most prevalent. Grossly, large numbers of nematodes were present in infected stomachs (for C. rudolphii intensity was 1–34 and 3–57 nematodes in male birds and 1–21 and 1–32 in females; for C. microcephalum 1–2 and 1 in male birds and 1–2 in females; for C. multipapillatum 2 in male cormorants and no infection in females; for C. chubutensis 1–2 and 1 in male birds and 1–5 and 1 in females and for E. tubifex 1–5 nematodes in male birds and 2–8 in females). Ulcerative inflammation and hyperaemia were the most common pathological presentations, especially in areas that had been invaded by parasites. Microscopically, varying degrees of granulomatous inflammatory reactions were seen, in addition to degenerated nematodes which appeared to have deeply penetrated mucosal surfaces and were surrounded by fibrous connective tissues.

Ayam petelur merupakan ayam yang khusus dipelihara untuk diambil telurnya. Kandungan protein telur yang tinggi serta harganya yang terjangkau membuat ayam jenis petelur ini banyak dibudidayakan. Namun dalam pembudidayaannya masih sering terdapat kendala, salah satunya disebabkan oleh berbagai nematoda yang menyebabkan berbagai macam infeksi. Penelitian ini telah dilaksanakan pada bulan April 2017 sampai bulan Juni 2017. Pengambilan sampel dilakukan di Peternakan mandiri, di Kelurahan Tegal Sari, Kecamatan Gading Rejo, Kabupaten Pringsewu, Provinsi Lampung dan identifikasi dilakukan di Balai Veteriner Lampung. Tujuan penelitian ini adalah untuk mengetahui jenis telur nematoda dan mengetahui nilai prevalensi parasit tersebut pada ayam.petelur. Metode pengambilan sampel yang digunakan pada penelitian ini adalah purposive sampling, yaitu mengambil sampel feses dari setiap kandang yang diduga terinfeksi nematoda sebanyak 100 sampel. Penghitugan jumlah telur parasit menggunakan uji Mc. Master. Hasil penelitian pada ayam strain ISA Brown ditemukan nematoda Ascaridia galli, Heterakis gallinarum dan Syngamus trachea. Nilai prevalensi serangan nematoda paling tinggi sebesar 43% oleh Ascaridia galli dan nilai prevalensi paling rendah sebesar 4% oleh Syngamus trachea.

AbstractIn Great Britain free-living common pheasantsPhasianus colchicusare often managed at high densities owing to their popularity as a quarry species. They are prone to infection by a range of parasite species includingHeterakis gallinarum,Capillariaspp. andSyngamus trachea. In 1995 the efficacy of an indirect anthelmintic technique for controlling parasitic worm burdens of pheasants was determined in a pilot study on a shooting estate in the south of England. Between 2000 and 2003 a large-scale field experiment was conducted on nine estates in eastern England to determine the effect of the technique on parasite burden and pheasant breeding success. In the absence of anthelmintic treatment worm burdens increased rapidly through March and April, whereas birds given anthelmintic-treated grain had lower worm burdens during the same period. The breeding success of pheasants was significantly higher on plots provided with anthelmintic treatment, although no long-term increases in population densities were observed. The burdens of the most common parasiteH. gallinarumwere significantly lower in pheasants from treatment plots six weeks after the anthelmintic treatment had ceased, but spring treatment did not influence parasite burden in the following winter.
