BACKGROUND AND OBJECTIVES: Hydatid cyst is the larval stage of the tapeworm Echinococcus granulosus. Hydatid cyst fluid, cyst membrane and Protoscolices, contain a complex mixture of antigens that can induce immune responses in the host. Anti-cancer properties of Protoscolices and hydatid cyst fluid has been shown. In order to identify antigens of hydatid cyst fluid that have anti-cancer effect, in this study production of monoclonal antibodies against one of the hydatid cyst fluid band (40KDa) has been investigated...

Cystic echinococcosis is caused by the larval stage of the dog tapeworm, Echinococcus granulosus. The disease is recognized as one of the world's major zoonoses affecting human beings and domestic animals apart from its economic and public health importance. Development of the cysts in the intermediate host such as buffaloes occurs in the lungs, liver and other organs. In this study, detection of circulating antigen in the diagnosis of cystic echinococcosis in buffaloes was done using enzyme linked immunosorbent assay and Dot-Enzyme immunoassay (Dot-EIA)...

The protective role of Sickle Cell Trait (SCT) in malaria endemic areas has been proved, and prevalence of HbS gene in malaria endemic areas is high. Splenic infarction is a well-known complication of SCT, while the association with malaria is considered rare. A Nigerian boy was admitted to our ward after returning from his country of origin, for P. falciparum malaria. He underwent abdominal ultrasound for upper right abdominal pain, showing cholecystitis and multiple splenic lesions suggestive of abscesses...

Calcification, or mineralisation, can occur as part of a natural process, or by pathological processes. The purpose of this work is to examine an unidentified semi-spherical and perforate hollow mass, found near the pelvis of an adult female, dated 12th-13th century AD, exhumed of the Church of Santo Domingo de Silos (Prádena del Ricón, Madrid, Spain). The mass was examined by SEM and Energy Dispersive X-Ray Spectroscopy. These procedures revealed a heterogeneous inner surface with both smooth and irregular areas...

The heart may be affected directly or indirectly by a variety of protozoa and helminths. This involvement may manifest in different ways, but the syndromes resulting from impairment of the myocardium and pericardium are the most frequent. The myocardium may be invaded by parasites that trigger local inflammatory response with subsequent myocarditis or cardiomyopathy, as occurs in Chagas disease, African trypanosomiasis, toxoplasmosis, trichinellosis and infection with free-living amoebae. In amoebiasis and echinococcosis, the pericardium is the structure most frequently involved with consequent pericardial effusion, acute pericarditis, cardiac tamponade or constrictive pericarditis...

Echinococcus granulosus is a parasite that can be seen throughout the world. So far, five species of genus Echinococcus have been identified as parasite in people: E.granulosus, E.multilocularis, E.vogeli, E.oligarthrus, E.shiquicus. Larval (metacestod) form of parasite settles in internal organs of hoofed animals (cattle, goats, pigs, horses, sheep, etc.) and human; the adult form is found in small intestine of final host, canine. Disease caused by parasite called as "Cystic echinococcosis" (CE) is an important health problem and causes economic losses in many countries including our country that livestock is common...

Rodents are important intermediate and paratenic hosts for carnivore parasites, including the important zoonotic agents Toxoplasma, Echinococcus and Toxocara. Monitoring of such parasites in rodents can be used to detect increasing risks for human and veterinary public health. Rodents were trapped at four sites in Berlin, two near the city center, two at the periphery. PCRs were conducted to detect Coccidia (target ITS-1) and specifically Toxoplasma gondii (repetitive element) in brain and ascarids (ITS-2) in muscle or brain tissue...

Although local prevalence of Echinococcus multilocularis may be high, this zoonotic parasite has an overall low prevalence in foxes and rodents in Sweden. To better understand opportunities for E. multilocularis transmission in the Swedish environment, the aim of this study was to investigate other taeniid cestodes and to relate observed patterns to E. multilocularis. Cestode parasites were examined in fox feces and rodents caught in different habitats from four regions of Sweden. Arvicola amphibius and Microtus agrestis were parasitized with Versteria mustelae, Hydatigera taeniaeformis s...

Echinococcus multilocularis is a most pathogenic zoonotic tapeworm that causes devastating echinococcosis in both humans and animals. Circulating microRNAs (miRNAs) are stably existed in the serum/plasma of mammalian hosts during helminthic infection. In this study, we compared the host-circulating miRNA expression in the sera from the E. multilocularis-infected and uninfected mice. A total of 58 host-origin serum miRNAs were differentially expressed (2 ⩾ fold change, P < 0·05), of which 21 were upregulated and 37 were significantly downregulated...

Alveolar echinococcosis (AE) is an emerging zoonotic disease caused by the cestode Echinococcus multilocularis. The secondary infection model of AE is based on intraperitoneal injection of disease-causing metacestodes into the peritoneal cavity of mice, which allows investigations on novel drugs or immunotherapeutical treatment options in vivo. So far, such in vivo studies assessed exclusively the parasite weight at the endpoint of a given treatment period. We here developed an ultrasound (US)-based scoring system that allows to follow-up parasite development in the living animal, and provides insights into parasite growth during the treatment phase...

Effective and sensitive methods for the molecular detection of Echinococcus multilocularis in faecal samples of final hosts are crucial for the prevention and control of human alveolar echinococcosis and for studies on the epidemiology of the parasite. Little is known about the suitability of commercial test kits for isolating DNA of E. multilocularis from fox faeces and the performance of standard Polymerase Chain Reaction (PCR) protocols in relation to the quality of DNA extracted by these kits. We compared four different kits: ZR Faecal DNA MiniPrep™ (Zymo Research), FastDNA(®) SPIN Kit for Soil (MP Biomedicals), QIAamp(®) Fast DNA Stool Mini Kit (QIAGEN) and NucleoSpin(®) Soil Kit (Macherey-Nagel) for the extraction of DNA from E...

The parasitic tapeworm Echinococcus multilocularis is the causative agent of alveolar echinococcosis, a serious zoonotic infection present in Europe that can be fatal. The United Kingdom currently has E. multilocularis free status but the possibility of introduction exists, most likely via an imported or returning dog or other deliberately introduced animal that has not had anthelmintic treatment. We have developed a model to predict the probability of successfully eliminating a focal outbreak of E. multilocularis using a programme of anthelmintic bait distribution...

An IgM murine monoclonal antibody (MAb) was obtained against the excretory-secretory antigen (ES-Ag) of in vitro reared protoscoleces of Echinococcus granulosus (Batsch, 1786). Western blotting revealed that the MAb recognised a 20.6 kDa protein of this ES-Ag. The MAb was used in sandwich enzyme-linked immunosorbent assay (s-ELISA) for selective sensitisation of the solid phase with the protoscolex-specific protein from its ES-Ag and somatic antigen (S-Ag) to examine serum samples of 108 cows from a cystic echinococcosis (CE) endemic area for specific antibodies and to compare the results with those from necropsies and an indirect ELISA (i-ELISA)...

Because of widespread organ shortage, the transplant community has been exploiting more and more so-called "extended criteria" donors. In this scenario, liver grafts harboring benign tumors or large cysts represent an infrequent but potentially valuable source of viable grafts. We depict a challenging case of liver transplantation performed using a graft harboring two large Echinococcus granulosus hydatid cysts in close proximity with the hilar plate and complicated by cystobiliary communication. Although liver transplantation using grafts with hydatid cyst has been rarely reported (three published cases), our case was peculiar as one of the cysts was located close to the hilum and was ruptured into left hepatic duct...

BACKGROUND: Larvae of the tapeworm E. multilocularis cause alveolar echinococcosis (AE), one of the most lethal helminthic infections in humans. A population of stem cell-like cells, the germinative cells, is considered to drive the larval growth and development within the host. The molecular mechanisms controlling the behavior of germinative cells are largely unknown. METHODOLOGY/PRINCIPAL FINDINGS: Using in vitro cultivation systems we show here that the EGFR/ERK signaling in the parasite can promote germinative cell proliferation in response to addition of human EGF, resulting in stimulated growth and development of the metacestode larvae...

The number of interventional treatments for hepatic cystic echinococcosis is increasing, but the chemicals or high temperatures used in these methodologies cause biliary complications, thus limiting their clinical applications. This experimental study aimed to apply a novel, non-thermal, non-chemical ablation method termed nanosecond pulsed electric field (nsPEF) for the treatment of human hepatic cystic echinococcosis. The nsPEF treatment parameters against protoscolices from human hepatic cystic echinococcosis were optimized in vitro...

The neozoan species raccoon dog (Nyctereutes procyonoides) and raccoon (Procyon lotor) are widespread in Europe and potential vectors of many diseases that can threaten human and domestic animal health. Facing a further spread of these species, it is important to know about (i) pathogens imported and/or (ii) pathogens acquired in the new habitat. Thus, we investigated the parasite fauna of wild raccoon dogs and raccoons from Austria, at the edge of their new distribution range. The eight examined raccoons were nearly free of pathogens including Baylisascaris procyonis, and thus assumed to have a low epidemiological impact, so far...
