The activation of peritoneal macrophage effector functions after therapy with free PZQ and PZQ incorporated in liposomes (lip.PZQ) was studied in the Mesocestoides corti-mouse model system. Each drug formulation was administered to an infected group of mice in 6 daily doses from day 14 p.i. Phagocytic activity of macrophages increased significantly after(More)
Infection of Trichinella spp. is widespread among wildlife in Slovakia and the red fox (Vulpes vulpes) is the main reservoir of Trichinella britovi. Trichinella spiralis has been rarely documented in sylvatic and domestic animals of this country. During routine examination of domestic pigs at the slaughter, Trichinella larvae were detected by artificial(More)
Selected immunological parameters in healthy mice and mice infected with Echinococcus multilocularis and the effect of free and liposomized albendazole (lip.ABZ) upon these parameters in relation to the reduction of parasite growth were investigated over 26 weeks. Proliferative response of splenic T and B lymphocytes, number of CD4+ and CD8+ spleen T cell(More)
Alveolar echinococcosis (AE), caused by proliferating metacestodes of the parasitic fox tapeworm Echinococcus multilocularis, is a life-threatening disease in humans. In this study we report four human cases of AE in Slovak Republic with regard to various clinical manifestations and susceptibility to chemotherapy with albendazole or mebendazole. Patients(More)
The parasite burden in the liver and peritoneal cavity, and antibody levels directed to whole worm extract, have been monitored in serum from ICR-strain mice, infected orally with 55 tetrathyridia of Mesocestoides corti (Cestoda, Cyclophyllidea). The subcurative does (3x or 6x) of praziquantel (PZQ) (10 mg.kg-1 body weight) were administered to mice from(More)
A case of the human ocular dirofilariosis in 72-year-old man from southern Slovakia is documented. Two days before visiting a doctor he noticed a live worm in his right eye. The eye was inflamed and itching. The worm of 100 mm in length was isolated from the subconjunctival space. On the basis of morphological appearance, histological examination and(More)
Beta-glucans are immunomodulators able to activate innate immunity and to potentiate acquired immune reactions. We investigated the impact of co-administration of liposomized beta-glucan on the larvicidal effect of the anthelmintic praziquantel (PZQ) in the livers and peritoneal cavities in mice infected with Mesocestoides vogae (M. corti). Also, within 2(More)
Dirofilariosis is considered to be the arthropod vector-borne disease with the fastest spread in Europe. Slovakia belongs to new endemic regions for canine and human infections. This paper reports the fourth human case, where diagnosis was confirmed using computed tomography (CT), histological and molecular examinations - for the first time in this endemic(More)
Establishment rate of Haemonchus contortus in non-suppressed and immunosuppressed gerbils within 14 days post-infection was compared after inoculation with 1,000 third-stage larvae (L3), exsheathed BZ-susceptible larvae. Based on significantly higher number of larvae in gerbils receiving low doses of immunosuppressant agent hydrocortisone, development of(More)
The effects of in vitro exposure to praziquantel (PZQ), liposomized PZQ (lip.PZQ), and empty liposomes on the surface morphology and motility of Mesocestoides vogae tetrathyridia were investigated using scanning electron microscopy (SEM) and a motility apparatus. Examination of treated larvae showed an effect that was concentration- and time-dependent,(More)
