Effects of Anisakis simplex larvae on blood parameters of experimentally infected Syrian hamsters, Mesocricetus auratus (Waterhouse)

The paper summarises a part of studies on Anisakis simplex (Rudolphi, 1809) larvae carried out in the Fish Diseases Department under the supervision of the late Dr Jadwiga Grabda. The experiment involved twenty eight Syrian hamsters assigned to three groups and fed the larvae. Anatomo-pathological changes in the experimental animals were assessed and some blood parameters analysed

Changes in the iron level in the organs and tissues of wels catfish, Silurus glanis L. caused by nickel

Bioaccumulation of nickel and the effect of nickel on the iron level in the tissues and organs of wels catfish, Silurus glanis L. were studied in the course of the present work. A number of blood parameters were determined e.g. erythrocyte count (RBC), leukocyte count (WBC), haemoglobin concentration (Hb), haematocrit value (Ht), and erythrocyte indices (MCH, MCV, MCHC) were calculated. On stained blood smears erythrocytes and leukocytes were differentiated. Effect of nickel on the activity of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in the blood serum was studied

Parasite fauna of selected fish species of lake Miedwie

A total of 136 fishes, representing 9 species (perch, Perca fluviatilis L.; pike, Esox lucius L.; European eel, Anguilla anguilla (L.); common bream, Abramis brama (L.); roach, Rutilus rutilus (L.); tench Tinca tinca (L.); European whitefish, Coregonus lavaretus (L.); vendace, Coregonus albula (L.); and zander, Sander lucioperca (L.)), from Lake Miedwie were studied within 1997-1999. The necropsies yielded 41 parasite species (taxa). The most diversified were parasite faunas of pike (19 parasite species) and perch (16 species) The parasites found represented 13 higher taxa: Monera, Fungi, Protista, Myxozoa, Monogenea, Cestoda, Digeoea, Nematoda, Acanthocephala, Branchiura, Copepoda, Mollusca, and Acarina. The parasites affecting fishes of Lake Miedwie exbibited diversified host-specificity. The most fish species were infectcd by metacercariae of Diplostomum spp. (8 fish species) and Tylodelphys clavata (1). Three fish species harboured: Ichthyocotylurus platycephalus, Ergasilus sieboldi, and glochidia Unionidae gen. sp. white Dermocystidium sp., Trichodinella epizootica, Henneguya psorospermica, Triaenophorus nodulosus, Posthodiplostomum cuticula, and Camallanus lacustris parasitised two host species. The remaining parasites were found in single fish species

Parastic fauna of Arctic charr, Salvelinus alpinus (L., l758) from the Hornsund region (Spitsbergen)

Parasites found in 64 individuals of Salvelinus alpinus were identified. A total of 5 parasitic species belonging to 3 higher tax were found. Plerocercoids of Diphyllobothrium sp. cestodes occurred between the peritoneal membrane and ventral muscles as well as in the stomach walls. Individuals of the cestode Eubothrium salvelini were found occurring in the stomach, intestine, and pyloric caeca. Philonema sp. nematodes occurred in gonads, on the peritoneum, and in the body cavity. The latter housed also another nematode which could not be identified. Females of the copepod Salmincola edwardsii were found on the gills. The data collected made it possible to determine the invasion incidence, intensity, mean intensity, and mean invasion intensity in population
