Environmental risk factors associated with amoebic gill disease in cultured salmon, Salmo salar L., smolts in Ireland.

A 2-year study was carried out on amoebic gill disease (AGD) involving monthly samples of 1+ Atlantic salmon, Salmo salar L., smolts, histological assessment of the gills and analysis of environmental data. Gill pathology was seen before amoebae could be detected microscopically. These changes in gill integrity were associated with marine environmental conditions, particularly elevated ammonium, nitrite and chlorophyll levels. The results suggest that the environmental changes predispose salmon to colonization by amoebae and ciliates. High densities of histophagous scuticociliates were observed in the gills during periods of advanced gill pathology. A number of different amoebae were observed in close association with gill pathology. Neoparamoeba was not seen in high densities, nor was it associated with gill pathology, indicating that Neoparamoeba may not be the primary agent of the AGD in Irish salmonid culture.

Evaluation of anthelmintics, antiprotozoal drugs and ectoparasiticides for racing pigeons (Columba livia var. domestica) available in The Netherlands.

Anthelmintics, antiprotozoal drugs and ectoparasiticides specially marketed for use in racing pigeons (Columba livia var. domestica) were evaluated by comparing dosages and indications given by the producers with data obtained from efficacy studies or empirical data. Of a total of 63 products, 59% were in accordance with the literature. Fifty-nine percent of the dosages and indications of anthelmintics were in accordance with scientifically obtained data, while for trichomonacides, coccidiostats and ectoparasiticides the figures were 47%, 59% and 100% respectively. Public health aspects of the consumption of medicated pigeons are discussed.
