Opis:
Prostaglandins have been already pretty well rccognized as metabolic regulators in vertebebrata tissues mainly in mammals. Less reports concerned the occurrence of prostaglandins in invertebrates. In the present review we summarise literature data about the presence of prostaglandins and other eicosanoids in various groups of parasites and their possible role in hostparasite interaction. Prostaglandins have also been found in very primitive organisms as bacteria, varions plants and protozoa. We summarise that prostaglandins seem to be a very ancient group, going back to the roots of evolution. They are as universal in cell physiology as DNA in genetics. In host-parasiter eicosanoids also parasitic origin, play an important role as a modulators of hosts immune responsiveness.

Opis:
Occurrence of nematodes (mostly dominating and common species of Porrocaecum ensicaudatum and P. semiteres) in host populations of birds (Turdus merula, T. philomelos, Sturnus vulgaris and Scolopax rusticola) was summarized in frequency distributions, and tests of agreement with the Poisson model as well as the modified binomial have been computed. Comparisons of the observed frequencies with the expected ones showed the high values (3 - 257) of the coefficient of dispersion, the so-called „overdispersion", characteristic for the negative binomial which is an extension of the Poisson model. A nearly perfect fitness of the counted (observed) with the expected frequencies was found for S. vulgaris both in the analysis of nematode metapopulation and their common species of P. ensicaudatum. Some deviations from the expectations were found for tracing of all nematode species distributions in T. merula, T. philomelos. On the other hand, the same model (negative binomial distribution according to moment method) has fitted quite well to each for common or dominating, nematode species.

Opis:
Results of micromorphological and histological studies of larvae of Trichinella Spiralis and T. pseudospiralis, as weil as, muscles, liver and small intestine of the rat-host before and after biostimulator administration of phytohemagglutinin and phytoanthelminthic were presented. It has been established that rats with Trichinella larvae of both species developed unspecific allergic angiomyositis, hepatitis, cholangitis, and erosio-haemorrhagic enterocolitis in the host's organism on the 35th day after infection. Furthermore, processes of compensatory hypertrophy, that support the host's (rats) homeostasis, on cell and tissue levels, were observed at histodestructional and morphofunctional deficiency. lt has been revealed that phytohemagglutinin, biostimulator injected into the host's organism before infection, is of immunostimulating nature and partially destroys the larvae of Trichinella. The phytoanthelminthic produces a significant trichinellocide effect: RNA synthesis and glycogen is intensified in the organs of the treated animals, their pathomicromorphogenesis weakened, and their compensatory and regenerative processes were observed. The combined use of the phytohemagglutinin and phytoanthelminthic fails to intensify the mentioned effect.

Opis:
The potential tertiary structure of Ancylostoma ceylanicum cysteine proteinase was obtained by Automatic Program 3D-JIGSAW and used for finding homologues of known structure by VAST program. The results of computational analysis showed the presence of domains recognizing host immunoglobulins. Based on this analysis we suggest that this protein is involved in cleaving of host antibodies and therefore it may be promising vaccine candidate. In this paper we present the computational analysis of parasitic antigen which is very helpful in evaluation of the potential role of this protein.

Opis:
The monogenean ectoparasite genera Dactylogyrus and Gyrodactylus are hyperdiverse, and yet monogenean communities infecting freshwater fish in the northern Holarctic are variable and often impoverished. This is a result of extinctions during periods of glaciation when the host fishes experienced range contraction. Fish species recolonised northern Europe by one of three routes; stenohaline fishes recolonised from the Black Sea basin via DanubeRhine or Dnieper−Dniester−Vistula connections. These fish retain complex rich monogenean faunas with numerous species of Dactylogyrus and Paradiplozoon. Anadromous fishes, recolonising via marine migrations along the coast, and cold−water fishes surviving in refugia close to the ice sheets, have impoverished monogenean faunas, characterised by gyrodactylid and ancyrocephalid species. However, there may be great complexity, due to the evolution of new hostparasite interactions within specific watersheds before, during and after the Last Glacial Maximum (LGM). This is demonstrated using examples from the sticklebacks (Gasterosteus aculeatus) and the bullheads (Cottus gobio). Finally, the evolution of Gyrodactylus salaris from a clade of G. thymalli is described, and the role of glaciation in stimulating the evolution of numerous clades of the latter is discussed. This latter example represents a unique opportunity to study speciation by host shift in real time.

Opis:
The tapeworm species Cloacotaenia megalops (Nitzsch in Creplin, 1829) is characterized by a very specific morphology. A particularly distinct feature is a large almost square scolex in which four fleshy suction cups are embedded and a rudimentary rostellum. During standard studies of wild duck cestode fauna in northwestern Poland, some morphological differences were observed among specimens, mainly in the shape of scolices and hermaphroditic proglottids of C. megalops isolated from different bird species. This paper attempts to demonstrate the impact of the host species on morphology of the parasite. The study material consisted of 39 individuals of C. megalops (19 from Aythya fuligula, 10 from Anas platyrhynchos, 4 from Bucephala clangula, 4 from Aythya marila and 2 from A. ferina). The isolated parasites were fixed and stored in 70% ethanol and solid preparations were made. Selected external and internal structures of the parasite were measured and photographed using a Zeiss microscope, a microscope camera Opta Tech 2.1 and Opta View 6.0.2.2. It was stated that the sizes of the most important elements of the parasite morphology are generally consistent with those presented in the available literature, nevertheless some differences were observed in both morphology and sizes of some anatomical structures, especially in the form of scolices and hermaphroditic proglottids between specimens isolated from hosts representing three different eco-tribes (Aythyini, Anatini and Mergini).

The low doses of α-chymotrypsin inhibitor (40-80 mg/kg/day) significantly decreased the number of live fetuses per litter, increased the number of fetal resorptions. The symptoms of matemal toxicity that occurred after administration of the highest doses of the inhibitor (80-300 mg/kg/day) to pregnant mice included: decreased body weight gain as compared to control, vaginal hemorrhage, intrauterine resorption of litters, abortions, altered behaviour of animals immediately after injection and death. There is a linear interrelationship between the logarithm of the doses of the inhibitor and mortality of pregnant mice. The DL50 value of the inhibitor for female was 116 mg/kg /day (confidence interval: 95.5-140.0 mg/kg/day).

Opis:
The role of glutathione-S-transferase (GST, EC 2.5.1.18) in biochemical host defence in experimental trichinellosis was evaluated. The activity of GST in mouse skeletal muscles was measured during the muscular phase of trichinellosis, starting from the 3rd week post infection (w.p.i.) to the 11th w.p.i. Activity was determined spectrophotometrically by monitoring the formation of thioether (S-2,4-dinitrophenylglutathione) from the reduced form of glutathione and 1-chloro-2,4-dinitrobenzene used as a substrate and as an example of xenobiotics. The changes in the activity of GST were as follows: an increase in activity starts in the 4th w.p.i., peaks (up to 310% of the normal value) in the 6th w.p.i., decreases in the 8th week and a final, weak rise was observed in week 11. The statistically significant changes in GST activity in this phase of experimental trichinellosis suggest that this enzyme participates in the biochemical defence of the host against Trichinella infection.

Introduction. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on metabolism of glycogen and trehalose of the host was studied. Material and methods. Last instar larvae (L₇) of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae. At 6, 12, 18 and 24 h after infection concentrations of trehalose and glycogen as well as activity of trehalase and α-amylase were determined. Results. The content of glycogen was lower in insects infected with S. feltiae than in the controls and animals infected with S. affinis. The content of trehalose was higher in insects from both infected groups than in the controls. Its concentration was slightly higher in larvae infected with S. affinis than in those infected with S. feltiae. The activity of α-amylase after infection with S. affinis was low. It was significantly higher in insects infected with S. feltiae. In animals of both infected groups, following a significant reduction at 6 h, the activity of trehalase remained at a similar level, higher than in the controls. In the paper the effects of infection with (i) different species of entomopathogenic nematodes and (ii) the importance of the developmental stage of the insect-host for changes in its metabolism of glycogen and trehalose were discussed.

Background. Macoma balthica is the major zoobenthic species in the Gulf of Gdańsk. Material. Two (4.2%) of the 48 M. balthica specimens collected in 2002 from the depth of 40 m were found to harbour metacercariae−containing sporocysts of Parvatrema affinis (Jameson et Nicoll, 1913) James, 1964. Results. The paper reports morphoanatomical dimensions of 30 sporocysts and metacercariae. Due to the common occurrence of the intermediate (Macoma balthica) and definitive (anseriform and charadriiform birds) hosts of P. affinis in the Gulf of Gdańsk, the trematodes are regarded as a constant component of the local biocoenose.

Opis:
This review aims to summarize our most recent knowledge of the unique mechanisms employed by digeneans to complete their complex life cycles. It is based on validated data from scientific literature and integrates both authors’ personal experiences. Several dynamic strategies utilized by digeneans are discussed in relation to their presence in three environments: aquatic, semi-aquatic and terrestrial. The following topics are discussed: transmission from host to host, which involves transmission of free-living stage of miracidium and cercaria: in active transmission – specific responses to environmental signals showing the presence of potential hosts (several papers of Haas et al.); in passive transmission – trophic transmission and mimicry by way of resemblance to natural food of potential host; and finally, transmission of the parasitic larvae (metacercaria and mesocercaria) – trophic transmission, manipulation of host behavior, and incorporating the intermediate host into food web of definitive host. This review also highlights several types of behavioral manipulations, including compensatory processes (Poulin, Lefèvre et al., Thomas et al.), and other mechanisms of manipulation (de Jong-Bring et. al). State-dependent alternative cycles demonstrating the difference between the terms „life cycle” and „life history” (Poulin, Thomas et al.) and the concept of „shared phenotype” (Lefèvre et al.) are also discussed.
