The life history and pathology of Sanguinicola klamathensis Wales in Salmo clarki henshawi Gill and Jordan at Hagerman National Fish Hatchery, IdahoEvans, Wallace Arwood 01 August 1973 (has links)
There are only three species of blood flukes known in salmonids in the world. Wales (1958) described two, Sanguinicola davisi and S. klamathensis, while Meade and Pratt (1965) described Cardicola alseae.

The incidence and life cycle of Diplostomum spathaceum in UtahEvans, R. Scott 01 April 1976 (has links)
Diplostomum spathaceum (Rudolfi 1819), (Diplostomidae) the fish eye fluke which causes the disease diplostomatosis, was reported in Utah by the Division of Wildlife Resources in 1974. Previous to this date diplostomatosis was suspected to occur in three reservoirs in the state. Diplostomatosis, whi.ch is due to the presence of the metacercarial stage of this parasite, causes cataracts of the lens. The incidence of the disease in Utah has generated public and academic concern.

Prevalencia de Fasciola hepatica en Bovinos beneficiados en el Centro de Faenamiento FRILISAC entre los años 2012-2015Cordero Calderón, Karem Fiorella January 2016 (has links)
La distomatosis bovina es una enfermedad que afecta enormemente a la ganadería a nivel nacional, no solo por la enfermedad en sí; si no también por las grandes pérdidas económicas que ocasiona y además por ser un problema en salud pública. Es causada por el tremátodo Fasciola hepatica y necesita del caracol del género Lymnaea para que se desarrolle su ciclo biológico. Este estudio tiene como objetivo determinar la prevalencia de Fasciola hepatica en bovinos beneficiados en el Centro de Faenamiento FRILISAC entre los años 2012 al 2015. Se evaluaron 48 Registros mensuales regionales de animales para beneficio según especie, sexo y procedencia del SENASA y 48 Consolidados mensuales de animales beneficiados y peso de carcasa según especie y sexo del SENASA pertenecientes al periodo de tiempo comprendido entre el mes de enero del 2012 hasta diciembre del 2015, de los cuales solamente se utilizó la información correspondiente a los bovinos y su procedencia; se almacenó por cada mes en una base de datos del programa Microsoft Office Excel y se analizó con tablas de frecuencias estadísticas. Los resultados demostraron que se benefició un total de 267 408 bovinos de los cuales 7 680 resultaron positivos a Fasciola hepatica, dando una prevalencia de 2.87%, en donde septiembre registra la mayor prevalencia con 5.29% (1219/23025) y de Junín registra la mayor prevalencia con 4.47% (830/18551). Además, se determinó que existió U$S 128 906.19 en pérdidas económicas directas producidas por el decomiso de hígados de bovinos parasitados con Fasciola hepatica.Bovine flukes is a disease that greatly affects livestock nationwide, not only by the disease itself; but also by large economic losses and also for being a public health problem. It is caused by the trematode Fasciola liver and needs snail Lymnaea gender to their biological cycle develops. This study aims was determine the prevalence of Fasciola hepatica in cattle slaughtered at the Center for Slaughtering FRILISAC between 2012 to 2015. Forty eight regional monthly records for the benefit animals were evaluated according to species, sex and origin of SENASA and 48 monthly Consolidated benefit animal and carcass weight per species and sex of SENASA belonging to the period between January 2012 to December 2015, of which only the share of cattle information and the source is used; It was stored for each month in a database of Microsoft Office Excel program and analyzed with statistical frequency tables. The results showed that a total of 267,408 cattle benefited 7,680 were positive to Fasciola hepatica, giving a prevalence of 2.87%, where in september recorded the highest prevalence with 5.29% (1219/23025) and Junín records higher prevalence with 4.47% (830/18551). In addition, it decided that there was U $ S 128 906.19 in direct economic losses caused by the seizure of parasitized livers of cattle with hepatic Fasciola.

Vývojová stádia motolic (Platyhelmintes: Trematoda) ve výuce / Larval Stages of Flukes (Platyhelmintes: Trematoda) in Secondary School EducationŠulcová, Hana January 2016 (has links)
The parasites are one of the most important factors that shape relationships in the nature. This thesis deals mainly with developmental stages of trematodes (Platyhelmintes: Trematoda), especially the cercariae of so-called Schistosomes and sporocysts of Leucochloridium paradoxum, as well as with and their intermediate host - freshwater snails. Introductory chapters are focused on general introduction into the topic, such as basic terminology or occurrence issue of trematodes (mainly schistosomes) in the world and in the Czech Republic. In order to determine larval stages of flukes and their morphological types, the research was conducted in four Prague localities with known presence of aquatic snails. Only in one site, Kunratická tůň Pond, the constant presence of echinostomous cercariae (and in lesser extent also furcocercariae) in Radix labiata was recorded during summer season of 2015. In small pond in the Botanical Garden of the Natural Sciences Faculty of Charles University and in Modřanské tůně Ponds, xiphidocercarie in Lymnaea stagnalis were found. No cercarie were detected in the pond in the Genetic garden of Charles University. The presence of Leucochloridium paradoxum in the European Amber Snail Succinea putris was confirmed in the vicinity of Modřanské tůně Ponds. The verified...

Interakce vajíček a miracidií Trichobilharzia regenti s nosní sliznicí kachen / Interactions of the eggs and miracidia of Trichobilharzia regenti with the duck nasal mucosaVlčková, Linda January 2018 (has links)
Trichobilharzia regenti is a nasal avian schistosome which has during the initial phase of infection an affinity to the nervous system. Larvae migrate through the central nervous system to the nasal mucosa of waterfowl, where they mature and reproduce. Until now this infection phase has been described only marginally. Adults are located in the nasal mucosa approximately from 13th to 24th day post infection. During this life phase, they migrate through the vascularized connective tissue and lay eggs, the presence of which has been detected in the tissue only. Maturation and hatching of miracidia occur in the tissue (unlike human schistosomes). The parasite causes inflammation, and the tissue is infiltrated with immune cells. Lymphocytes, granulocytes, macrophages, plasma cells and giant multi-nuclear cells were described by histological methods. The thesis is focused on a more detailed description of cellular immune response and histopathological changes of the tissue by means of histological stains, and antibody/lectin probes. The flukes were observed more frequently in the blood vessel lumen, together with a higher number of immune cells compared to the healthy duck. Infiltration by a high number of lymphocytes occurred in the tissue, the macrophages were frequently observed in clusters around the...
