Opis:
The influence of Heligmosomoides polygyrus on infection with Trichinella spiralis was studied in BALB/c mice. Mice coinfected with T. spiralis and previously given H. Polygyrus harboured both nematode species till day 34. The number of T. spiralis muscle larvae was greater in mice coinfected with H. polygyrus/T. spiralis or T. spiralis/H. polygyrus than after infection with T. spiralis alone. Infection with H. polygyrus did not enhance eosinophil and IL-5 levels induced by T. spiralis. Additionally, the production of IgG1 specific to LI T. spiralis was inhibited by co-infection. Changes in the levels of IFN-y and IgG2a implicated a disturbance in Th2 cell activation during protective response and resulted in the greater number of T. spiralis muscle larvae in coinfected mice.

Diphyllobothrium latum
Opis:
Diphyllobothrium latum typically occur in the subarctic and temperature zones of the Eurasian Continent, however it is also observed in the Arctic Region and Australia. Raw fish meat and raw shell-fish containing plerocercoids is the main source of human infections. Humans are the principial final host of D. /atum. Under primitive conditions human excrements with immature tapeworm eggs are deposited anywhere. After embrionic development which occurs in the water, the eggs are transformed into coracidia. Two intermediate hosts (cyclop and fish) are needed for further development. The free-swimming coracidium must enter the stomach of different species of Copepoda. After contact with the intestinal juice of the cyclop, the coracidium loses its ciliated envelope and the hooks become mobile. The metamorphosis of the oncosphere to the procercoid occurs. The discovery of the procercoid done by Janicki and Rosen in 1917 implied that the missing link in the cycle of the broad tapeworm had been found. The copepod including the procercoid is consumed by the second intermediate host. The larvae escape from the digestive tract of the fish and are transformed into a plerocercoid. The plerocercoids develop slowly in the fish, and they must reach a certain degree of maturity to be capable of infecting the final host. Today the life cycle of the tapeworm is well recognized and well illustrated in parasitological textbooks and websites. In this paper the history of the exploration of the D. latum life cycle is described. Additionally the main scientific researches carried out on life stages of the broad tapeworm have been reviewed.

Opis:
From the time of the discovery of Trichinella larvae in 1835 until the middle of the next century it was commonly assumed that all trichinellosis was caused by a single species Trichinella spiralis. This species is an intracellular parasite in both a larva and an adult stage. The L1 larvae live in a modified skeletal muscles. The adult worms occupy a membrane-bound portion of columnar epitelium, living as intramulticellular parasite. More than century later T. spiralis have been reported from more than 150 different naturally or experimentally infected hosts and demonstrated worldwide distribution in domestic and/or sylvatic animals. Up to date, Trichinella genus comprised eight species (T. spiralis, T. nativa, T. britovi, T. murrelli, T. nelsoni, T. pseudospiralis, T. papuae and T. zimbabwensisi) and three additional genotypic variants that have not yet to be taxonomically defined (T6, T8, T9). Molecular markers revealed that Trichinella T6 is related to T. nativa, Trichinella T8 related to T. britovi. Two main clades are recognized in the genus Trichinella: the first encapsulated in host muscle tissue and the second-non-encapsulated. In this paper the history of Trichinella spp. discovery, their life cycle, taxonomy and phylogeny have been reviewed.

Opis:
Introduction. The most important confirmative diagnostic test for trichinellosis is the presence of the muscle larvae in a tissue biopsy but this direct method has a low sensitivity of light and moderate infections. The aim of presented study was to compare the usefulness of the results obtained by three ELISA procedures for Trichinella spp. diagnosis in human outbreaks. Materials and methods. All sera (cases and controls) were tested for anti-Trichinella antibodies (immunoglobulin G) using commercially available Novatec KIT and two other ELISA procedures based on excretory-secretory (ES) antigens on Trichinella spiralis muscle larvae. The main differences in ELISA procedures were: the protein concentration in antigen, dilution of human serum samples, conjugate and the time of conjugate incubation. Additional differences were noticed in ES antigen preparation procedures as well as in T. spiralis isolates used in these procedures. Serum samples were obtained from 22 symptomatical patients from Poznań region (West Poland), geographic area where human outbreak had occurred. Control serum samples were obtained from 20 patients from an open population from a non endemic trichinellosis area. Results. The results were analyzed in terms of both: statistical and epidemiological point of view. Linear regression analysis and correlations coefficient r between OD values of total 22 patients obtained in three ELISA procedures were positive and high statistically significant. Three ELISA procedures revealed different cut-off values and positivity rates for outbreak. However, the majority of positive samples were found as positive in three procedures, but some of them were positive in two or one procedure only. These individual variability in sera reactivity observed in three ELISA procedures could be very important from epidemiological point of view.

Opis:
Three species of oribatid mites: Scheloribates latipes, Pergalumna nervosa and Ceratozetes sp. were experimentally infected with Moniezia expansa eggs or oncospheres. The intermediate hosts were kept under constant laboratory conditions at 27°C and 80% relative humidity. Three species of oribatid mites became infected and completely developed cestode cysticercoids were found. The early part of life cycle of M. expansa was studied in S. latipes. The mites were examined on 20th, 24th and 29th day after cestode oncosphera invasion. A fully fonned cysticercoid of M. expansa was observed on 29th day after infection. The mean of intensity of infection was 1-5 cysticercoides per mite. The infected and living oribatid mites could be kept under laboratory conditions for 7 months. The cysticercoides which had been recovered from S. latipes after this time were able to infect sheep.

Opis:
The paper presents different aspects of natural gastrointestinal nematode infection in this primitive, prolific Polish Wrzosówka breed of sheep. The study was carried out on the flock located at the farm run by Warsaw Agricultural University at Żelazna (central Poland) in 1995-1998. Egg counts per gram of faeces, larval differentiation, total white blood cell counts, blood eosinophil counts, interleukin-5 concentration, lymphocyte blastogenic activity and IgG immune response were discussed. The egg counts were overdispersed and followed a different pattem each grazing season. The larvae obtained from faecal culture belonged to 6 categories: Trichostrongylus spp., Haemonchus contortus, Teladorsagia spp., Cooperia spp., Chabertia ovina/Oesophagostomum spp. and Nematodirus spp. However there were no discemible pattems in the com position of nematode population over time. Data analyses have shown that egg counts, eosinophil counts, IL-5 concentration and IgG level in different months each year were repeatable. The results obtained in two divergent groups of sheep, chosen for consistently low or high faecal egg counts have been presented also. Polish Wrzosówka breed of sheep is under conservation breeding program based mainly on the markers of breed standard. The results obtained in this study revealed that some parasitological, haematological and immunological parameters should be added to this program.

Opis:
The work aimed at the establishment of the ovostatic action of Na₂HP³²O₄, dilombrine and piperazine on the eggs of Ascaris suum. The eggs were placed in Barbagalla fluid, 4 ml in each tube, with the density of 10000 eggs/1ml at the temperature of 26°. To the tubes with egg suspension was added radioactive Na₂HP³²O₄ at various concentrations so as to obtain radioactivity in the concentrations of (I) 1.5 μC/ml, (II) 3 μC/ml, (III) 4.5 μC/ml. Dilombrine, at the concentration of 0.1 mg/ml, 0,0l mg/ml and 0.001 mg/ml was added to one series of tubes with P³², and piperazine at the concentration of 20 mg/ml to the other series containing P³². The experiments demonstrated that P³² at the given concentrations did not affect essentially the development of eggs. A considerable inhibition in the development of eggs could be seen in tubes with dilombrine and it was proportional to the concentration of the drug. In tubes with piperazine solution there was also an inhibition in the development of eggs. The P³² cumulation in eggs placed in piperazine solution was at first 10 times less than in Na₂HP³²O₄ solution and a few times lower than in dilombrine solution.
