Actual programme of research and scientific activity:

Our laboratory is conducting the extensive comparative studies on: (1) embryogenesis in cestodes and trematodes by means of electron microscopy (TEM and SEM) and cytochemistry; (2) cellular organization of the infective larval stages of parasitic platyhelminths; (3) the post-embryonic development and ultrastructure of their larvae and juvenile forms. Several species selected for our studies are of medical and/or veterinary importance, such as three species of examined schistosomes, taeniid cestode including Echinococcus granulosus and E. granulosus, anoplocephalids, namely Inermicapsifer madagascariensis, Anoplocephaloides dentata, Mosgovoyia ctenoides and Moniezia sp. Obtained results allow us to elucidate mechanism of host infection and biology of parasite transmission and may represent successful contribution towards the fight against the examined parasites. In addition, new data on the gametogenesis, embryonic and post-embryonic development combined with new molecular data may provide useful information on phylogenesis, systematic and evolution of Platyhelminthes.
The Polish school of parasitology (K. Janicki, L. W. Wiśniewski, J. S. Ruszkowski, W. Michajłow, K. Rybicka, L. Jarecka) has a long tradition in this field of research and always significantly contributed towards its development and current progress. Our labolatory from a long period of time maintain close scientific cooperation with parasitologists from Bulgaria, Czech Republic, Spain, Russia, Switzerland, Ukraine, USA and United Kingdom, working in similar field of research.
The results of our research projects are published almost exclusively in the important international journal included on the ISI Master Journal List. They are frequently presented at both local and international conferences and congresses.

Parasitic fungi are promising candidates for microbiological control of insect pests. Fungi invade insect hosts penetrating their cuticle by a combination of mechanic pressure and enzymatic degradation. Growing fungi release a number of different cuticle-degrading enzymes: proteases, chitinases and lipases. Defense reactions of the host consist mainly of the cellular immune responses effected by the hemolymph cells (hemocytes) which can phagocytose or form multicellular capsules around foreign particles. In rare cases fungal infection stimulates appearance of fungistatic proteins in the insect hemolymph. Most parasitic fungi kill their hosts by some combination of mechanical damage produced by fungal growth and/or nutrient exhaustion. Some fungi rapidly kill insects by releasing toxic metabolites. Entomopathogenic fungi producing mycotoxins attract attention as a potential source of a new generation of insecticides.





The hemocytes from Galleria mellonella larvae

Current research:

  1. mechanisms of insect infection by a parasitic fungi :
    • identification of toxic fungal metabolites 
    • function of fungal enzymes in the process of infection
    • influence of culture medium’s ingredient on the insecticide potential 
    • the role of fungal metabolites in the functioning of the insects immune system 
  2. insect defensive reactions to the attack of parasitic fungi:
    • antimicrobial properties of the components of insect cuticle
    • define the role of each class of hemocytes in defense reactions of insects

Applied techniques:

  • gas chromatography with mass spectroscopy (GC / MS), liquid chromatography with mass spectroscopy (LC / MS),
  • light microscopy and fluorescent,
  • flow cytometry,
  • electrophoretic analysis,
  • Western Blot,
  • microbiological testing

Two main research fields of Laboratory are:

Trichinellosis  - zoonosis which is caused by eating raw or undercooked meat of animals infected with the larvae of a worm called Trichinella. Infection occurs in wild carnivorous (meat-eating) animals but may also occur in domestic pigs and wild boars.

Neosporosis - disease which is caused by a very small, one celled parasite called Neospora canium. This parasite has a worldwide distribution and is now recognized as a common cause of bovine abortion in dairy herds.


Larwy Trichinella in muscle


Larwy Trichinella isolated from the muscle

The distribution of Trichinella species in domestic pigs and in wild animals such as red foxes, wolves and wild boars in different regions of Poland is monitored.
Trichinella larvae have been collected after artificial digestion of the predilection muscle. The method is recommended by International Commission on Trichinellosis. 
Polymerase chain reaction (PCR) analysis have been used to identify larvae at the species level.
It has been found that Trichinella spiralis is the most frequent species in domestic pigs and wild boars. However the mixed infections T. spiralis and T. britovi have been noticed too. In red foxes, the majority of infections are caused by T. britovi.


Adult worms and new-born larvae isolated from the intestine


The prevalence of specific IgG antibodies against T. spiralis in domestic pigs and wild boars is monitored using immunoassay ELISA.


Since 2004, the usefulness of ELISA tests in T. spiralis detection in human infections has been studied. Sera from some outbreaks were checked using commercially available test as well as the protocols prepared in our lab. The results revealed that the protocols prepared in our lab detected much more positive sera than commercially available test.


Neosporosis - Neospora caninum, an apicomplexan protozoan has a world wide distribution. It caused economical losses due to reproductive failure associated with abortion among cattle. The study is done to check the level of specific antibodies against parasite using the ELISA test kit (IDEXX Lab., Inc., Westbrook, Maine, USA). More than 2500 dams belongs to 11 herds were examined. The prevalence of antibodies varied from 1,5% to 23%.

The cellular and humoral immune responses in pregnant cow during natural long lasting infection of N. caninum were examined. Non infected, pregnant cow was used as a control. Peripheral blood mononuclear cells were stimulated in vitro with Con A, LPS and N. caninum crude antigen. Serum specific IgG level was also examined. The results revealed limited changes in cell-mediated response and slight changes in humoral response in long lasting N. caninum infection in pregnant cow.



Tachyzoites of Neospora caninum in Vero cell

The identity of the parasite in the tissues of naturally infected calves was confirmed by polymerase chain reaction using specific oligonucleotide primers. Additionally, using PCR test, the presence of N. caninum DNA in milk and colostrum from seropositive cows was shown for the first time. The new Polish strain of N. caninum was isolated and it is maintained in vitro (Vero cell culture) and in vivo (gerbils). The Polish isolate was sent to the Moredun Research Institute in Edinburgh (Scotland) for further molecular studies.

Current research:

The Laboratory of Molecular Parasitology aims to discover and implement novel strategies to control parasitic diseases, such as fasciolosis, that affect the health of millions animals and humans worldwide.
We employ cutting-edge research in genomics, cell biology, immunology, epidemiology and biochemistry to discover new ways to combat parasitic disease. The Laboratory has a distinguished tradition of gastrointestinal helminth research, especially as related to vaccine development.


We have tested cDNAs encoding Fasciola hepatica vaccine candidates including glutathione S- transferase and cystein protease in laboratory (rats) and ruminant (sheep) hosts. These enzymes have been expressed in bacteria and/or baculovirus as well as plant systems and have been also tested for vaccine efficacy in rats and sheep using intranasal, oral and intramuscular routes of the antigen administration. We have found that intranasal vaccination may be feasible with both cDNA and protein forms of the cysteine proteinase.

Current research:

  • The subject of work of the Laboratory are investigations on the parasites of the European bison, cervids and beavers, their distribution, morphology, systematic, biology, differential diagnosis and also on the epidemiology, pathology and treatment of parasitoses provoked by them. The forest environment as a source of parasites for humans and animals is one of the most important problems undertaken in the laboratory.
  • The current topics of research are gastrointestinal nematodes from the family Trichostongylidae, lung nematodes from the family Protostrongylidae and tissue nematodes from the subfamily Onchocercinae. Furthermore, the dispersion of ashworthiosis of domestic and wild ruminants, the epidemiology of elaphostrongylosis of Cervidae and the threat it creates for domestic animals and people are investigated. Our research also concerns monitoring the status of helminth infections in the European bison in the Białowieża Forest and in cervids under farm breeding conditions.


  • „Molecular analysis of lungworms from the genus Dictyocaulus of free-roaming wild ruminants from Poland”. „Mobility Plus” - III edition, No 1105/MOB/2013/0, 2014-2015. Head of the project: dr Anna M. Pyziel. Location: SLU, Uppsala, Sweden. Mentor: Prof. Johan Höglund.


  • elaboration of the helminth fauna of Cervidae in Poland;
  • investigations on the forming of the helminth fauna of the European bison during 45 years of the restitution of this species;
  • detection and description of the genetic polymorphism of the nematodes from the subfamily Ostertagiinae;
  • elaboration of the theory of the parallel evolution of Nematodes (Trichostrongylidae) and their hosts (Cervidae);
  • investigations on species composition, morphology and differential diagnosis of tissue nematodes from the subfamily Onchocercinae in wild and domestic ruminants in Poland;
  • description of the morphology of eggs, invasive larvae and adults of the nematode Ashworthius sidemi;
  • statement of the endangerment of domestic animals by parasitoses of wildlife (parafasciolopsosis, elephostrongylosis, ashworthiosis);
  • description of clinical elaphostrongylosis of domestic ruminants.

The Laboratory of Parasitoses of Wild Animals can do service diagnostic examinations towards parasitical diseases of wild animals and coproscopic examinations of cervids in farm breeding conditions.
