Co-administration of silymarin elevates the therapeutic effect of praziquantel through modulation of specific antibody profiles, Th1/Th2/Tregs cytokines and down-regulation of fibrogenesis in mice with Mesocestoides vogae (Cestoda) infection.

Silymarin (SIL) represents a natural mixture of polyphenols showing an array of health benefits. The present study, carried out on a model cestode infection induced by Mesocestoides vogae tetrathyridia in the ICR strain of mice, was aimed at investigating the impact of SIL as adjunct therapy on the activity of praziquantel (PZQ) in relation to parasite burden, immunity and liver fibrosis within 20 days post-therapy. In comparison with PZQ alone, co-administration of SIL and PZQ stimulated production of total IgG antibodies to somatic and excretory-secretory antigens of metacestodes and modified the expression patterns of immunogenic molecules in both antigenic preparations.

Seroprevalence of Echinococcus spp. and Toxocara spp. in Invasive Non-native American Mink.

Invasive non-native species can become reservoirs of zoonotic pathogens and cause their spread during colonization, increasing the risk of zoonoses transmission to both wild hosts and humans. American mink (Neovison vison) are considered an important invasive mammal species responsible for carrying endoparasites. The aim of our study was to evaluate the role of feral American mink as a possible transmission vector of Echinococcus spp.

Seroprevalence of Toxoplasma gondii and Neospora caninum infection in sheep, goats, and fallow deer farmed on the same area.

Toxoplasma gondii and Neospora caninum are coccidian parasites with a global distribution that cause reproductive failure and production losses in livestock. The seroprevalence of both parasite species in ruminants and Cervidae has been investigated worldwide and found to vary greatly. Studies carried out on mixed flocks with 3 ruminant species (sheep, goats, and fallow deer) living under the same conditions are excellent models for identifying any differences in the rate of infection with the 2 parasites between the animal species.

A Community-Based Study to Estimate the Seroprevalence of Trichinellosis and Echinococcosis in the Roma and Non-Roma Population of Slovakia.

Trichinellosis and cystic and alveolar echinococcosis are serious parasitic diseases transmissible between animals and humans. Moreover, alveolar echinococcosis is considered one of the most dangerous of human helminthoses. Roma communities are particularly numerous in Central and Eastern Europe.

First Toxoplasma gondii isolate from an aborted foetus of European bison (Bison bonasus bonasus L.).

Prevalence of Toxoplasma gondii and Neospora caninum in red foxes in Slovakia.

Sera or meat juices of 177 red foxes (Vulpes vulpes) originated from the localities of a human-influenced landscape (Group 1) and 126 foxes from the protected mountain region (Group 2) of Slovakia, collected during 2010-2014 were tested for the presence of antibodies against Toxoplasma gondii using indirect ELISA and Neospora caninum by competitive ELISA. The tissue and uncoagulated blood samples were examined for the presence of the parasite's DNA. The total seropositivity to T.

Molecular screening for bacteria and protozoa in great cormorants (Phalacrocorax carbo sinensis) nesting in Slovakia, central Europe.

This study brings the data about the occurrence of bacterial and protozoan pathogens in 32 great cormorants (Phalacrocorax carbo sinensis), representing approximately 20% of the population nesting in the surroundings of water basin Liptovská Mara (northern part of Central Slovakia). A survey revealed the presence of tick-borne bacteria Anaplasma phagocytophilum (6.25%) and parasitic protozoa Toxoplasma gondii (3.

Wild boar (Sus scrofa) - reservoir host of Toxoplasma gondii, Neospora caninum and Anaplasma phagocytophilum in Slovakia.

In Central Europe the wild boar population is permanently growing and consequently Cf foodborne infections. In this study serological and molecular detection of Toxoplasma gondii and Neospora caninum in wild boars was evaluated. Moreover, same samples were screened for the presence and genetic variability of tick-borne bacterium Anaplasma phagocytophilum.

Human Trichinella infection outbreaks in Slovakia, 1980-2008.

Trichinellosis, a parasitic zoonosis with world-wide distribution, causes serious health problems in humans and is also of economic importance. In Slovakia the most frequent species is T. britovi, causing disease mainly in wild life species.

Immunodiagnostic approaches for the detection of human toxocarosis.

Human toxocarosis is an important zoonosis caused by larvae of Toxocara canis/cati. The objective was to evaluate the role of IgG anti-Toxocara antibody detection and the specific IgG avidity in diagnostics of human toxocarosis. Anti-Toxocara IgG antibodies and IgG avidity were evaluated by excretory-secretory (ES)-enzyme-linked immunosorbent assay (ELISA).

Neospora caninum - Associated Abortions in Slovak Dairy Farm.

Background: Neospora caninum is considered one of the major causes of repeated abortions in livestock. This study aimed to determine the seropositivity to N. caninum using indirect ELISA and the influence of the infection on the occurrence of abortions in selected dairy herd in Slovakia.

Evaluation of purified antigen fraction in the immunodiagnosis of cystic echinococcosis.

Echinococcus granulosus antigen B fraction (AgB) was evaluated for its prognostic value in the serological follow-up of cystic echinococcosis (CE), compared to crude hydatid fluid (HF) as well as soluble somatic Echinococcus multilocularis antigen (Em). The sensitivity and specificity of enzyme-linked immunosorbent assays (ELISA) were compared examining 177 sera from patients with different clinical courses and outcome of CE and with other parasitic infections. AgB-ELISA in comparison to confirmed cystic echinococcosis has 96.

Detection of antibodies to Neospora caninum in moose (Alces alces): the first report in Europe.

Neospora caninum Dubey, Carpenter, Speer, Topper et Uggla, 1988 is a protozoan parasite originally reported as a major cause of bovine abortions worldwide. It is documented that the parasite is widely spread among non-carnivorous cervids. The purpose of this study was to investigate the seroprevalence of N.

Toxoplasma gondii, Neospora caninum and tick-transmitted bacterium Anaplasma phagocytophilum infections in one selected goat farm in Slovakia.

Parasitic diseases of livestock together with poor welfare conditions can negatively affect the health status and production of small ruminants. Protozoan parasites and tick-borne infectious agents are common threat of livestock including small ruminants mostly during the pasture season. Therefore the priority of the study was to analyse the circulation and presence of two protozoan parasites Toxoplasma gondii and Neospora caninum as well as tick-transmitted bacterium Anaplasma phagocytophilum in one selected goat farm in Eastern Slovakia.

Kinetics of anti-Neospora antibodies during the period of two consecutive pregnancies in chronically infected dairy cows.

The course of anti-Neospora antibody kinetics during two consecutive pregnancies has been evaluated in five chronically infected dairy cows. The blood samples of cows were collected monthly. Anti-Neospora antibodies in blood sera were detected by indirect ELISA (ID-VET, France).

Occurrence and genetic characterization of Toxoplasma gondii in naturally infected pigs.

The protozoan Toxoplasma gondii is an obligate intracellular parasite that infects a wide range of warm-blooded vertebrates. The data about the occurrence of toxoplasmosis in slaughter pigs in the Slovak Republic are still missing. The aim of our study was to estimate the prevalence of toxoplasmosis in pigs from Slovakia during the period of 2006-2010 by ELISA and PCR methods.

Toxoplasma gondii is a protozoan parasite of great medical and veterinary importance. The aim of this study was to determine the seroprevalence of toxoplasmosis in wild boars hunted in the Slovak Republic in 2003. Examination of 320 wild boars revealed a seroprevalence of 8.

Climate and environmental factors influencing Echinococcus multilocularis occurrence in the Slovak Republic.

During the period of 2000-2004, 3,096 red foxes from the whole territory of the Slovak Republic were sampled and examined parasitologically for infections with Echinococcus multilocularis, causative agent of serious alveolar echinococcosis in humans. Relations between prevalence of the parasite in individual regions of Slovakia and some environmental factors were weighted. During the study period, great differences of prevalence and infection intensity were found on a regional level and significant between-year fluctuation of both parameters was observed.
