Wpływ pasożytowania larw Fasciola hepatica na ultrastrukturę wątrobotrzustki Galba truncatula L.

Ultrastructure of the digestive gland has been studied in G. truncatula, uninfected and infected with F. hepatica larvae. The digestive gland of G. truncatula consist of seccretory-resorption cells and calcareous cells. On the 20 day post infection the damage to the secretory cells were small and did not inhibit their activity. On the 60 day post infection the gland structure was totally altered: reduced height of secretory cells, lack of Golgi apparatus, myelin-like degradation of mitochondria, reduction and desintegrating of rough endoplasmic reticulum. These damage of secretory and calcareous cell to bring about a total inhibition of their secretory activities

Some specific and non-specific phosphatases in the sporocyst of Fasciola hepatica. 3. Enzymes associated with glycolysis

Using histochemical and cytophotometric methods, enzymes associated with anaerobie glycolysis: glucose-6-phosphatase, hexokinase, and aldolase in the developing sporocysts of Fasciola hepatica were studied. Highest activity of these enzymes was found in the germ balls in the sporocysts, at all phases of their development, which is related to intensive proliferation and differentiation of the embryos developing inside the germ balls

Demodex folliculorum and Demodex brevis (Acarida) as factors of chronic marginal blepharitis

Group 568 patients with chronic marginal blepharitis was investigated for the presence of Demodex folliculorum and D. brevis on palpebral margins. The parasites were found in 387 cases (68% examinated population). D. folliculorum-258 (67%) and D. brevis-129 (33%)

Aktywnosc sezonowa kleszczy Ixodes ricinus w biotopach nadwodnych i lesnych Szczecina i okolic oraz ich zakazenie kretkami Borrelia burgdorferi

The article presents the results of researche ( 1999-2000) on numbers and seasonal activity of Ixodes ricinus in selected lakesides and forests habitats of Szczecin and on occurence of the spirochetes Borrelia burgdorferi sensu lato in ticks. A total of 8065 ticks were collected from 6 localities: 647 larvae, 4549 nymphs, 1624 females and 1244 males. The spirochetes B. burgdorferi were found (using the PCR techniques) in 2271 specimens e.c. 28,1 % whole population. Numbers infected larvae were 216 (33,4 %), nymphs 1215 (26,7 %), females 490 (30,6 %), males 350 (28,1 %). This study shows that examinated habitats where I. ricinus is present are risk areas of human infection with Lyme disease spirochaetes
