The egg of Fasciola hepatica has a smooth surface with a slightly elevated circle marking the fracture of the operculum. The operculum and the aperture have crenated edges. The epithelial cells of the miracidium are covered with long cilia. When miracidia are vibrated in an ultrasonic cleaner the cilia of the epithelial cells of the four posterior tiers are broken off only leaving longitudinal rows of cilium stubs, whereas the cilia of the first tier are still retained. The apical papilla is provided with a dorso-ventral furrow, multiciliated pits and isolated sensory cilia. The narrow intercellular ridge is smooth, whereas the epithelial cells have small cytoplasmic knobs between the cilia. The penetration into the snail (Lymnaea truncatula) and the transformation into sporocyst may be separated into three phases. (1) Less than 1 min after attachment to the snail the ciliated cells of the anterior tier are shed and swim away. (2) The cilia of the remaining cells beat violently and after about 5 min most cilia are broken off near the cell surface. The miracidium remains for about 15 min embedded as far as the intercellular ridge receptors (lateral papillae and sheathed ciliated nerve endings). During this period extensive contraction and relaxation of the body are performed. (3) The final penetration of the snail epithelium takes about 15 min. Simultaneously with the penetration into the snail tissue the ?bald? cells (epithelial cells with cilium stubs only) of the four posterior tiers loosen, form globules and fall off. The surface below the cells is smooth and in cytoplasmic continuity with the intercellular ridge and the apical papilla, and this syncytium forms the later tegument of the sporocyst. After a few days the tegument of the sporocyst is provided with microvillus-like projections and the apical papilla and sensory structures are lost. 12 pp., 26 figs, gr. 8.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This Community meeting has been organised, since over the past 15 years in different countries of Western Europe including Scandinavia, a lot of research has been directed to the summer mastitis problem. Summer mastitis in cattle is a well known disease which, because of its abruptness and the difficulties concerned in defining the predisposing factors and the pathogens involved, is hard to control. Moreover, as it is anticipated that in the transmission of the bacteria one or more dipterans are involved, the complexity in defining the disease and hence co-ordinating our scientific knowledge in relation to practical control was stimulus enough for this workshop to be organised. Our aims can be summarised in the following goals: 1. Exchange of information in the practical, technical and scientific field in order to stimulate a co-ordinated research approach at a time in which the cattle husbandry sector is under great economical stress. 2. Inform research workers from countries where the disease is or seems to be, not endemic, on aspects that might be of interest for them in the approach of comparable problems. 3. To draw up conclusions and recommendations with regard to future research activities in order to avoid needless duplication of effort.…
