Echinococcosis is a parasitic zoonosis that is considered as a neglected disease by the World Health Organization. The species Echinococcus oligarthrus is one of the causative agents of Neotropical echinococcosis, which is a poorly understood disease that requires a complex medical examination, may threaten human life, and is frequently associated with a low socioeconomic status. Morphological and genetic diversity in E. oligarthrus remains unknown. The aim of this work is to identify and characterize E. oligarthrus infections in sylvatic animals from the Upper Paraná Atlantic Forest in the province of Misiones, Argentina, by following an integrative approach that links morphological, genetic and ecological aspects...

Echinococcus multilocularis is a tapeworm that may cause alveolar echinococcosis (AE), one of the most dangerous parasitic zoonoses. As in the case of some foodborne diseases, unwashed fruits and vegetables contaminated with eggs of E. multilocularis may serve as an important transmission route for this parasite. The aim of this study was to investigate the presence of E. multilocularis DNA in fruit, vegetables, and mushrooms in rural areas of the Pomerania province, Poland (non-endemic territory). In total, 104 environmental fruit, vegetable, and mushroom samples collected in forests, plantations, and kitchen gardens were analysed using nested PCR based on the mitochondrial 12S rRNA gene...

BACKGROUND: Alveolar echinococcosis is a potentially lethal zoonosis caused by larval forms of the tapeworm Echinococcus multilocularis. Humans are aberrant intermediate hosts who become infected by ingestion of egg-contaminated food or water or via physical contact with domestic or wild animals that carry the parasite in their small intestine. In humans, the disease usually affects the liver and can spread to other organs causing metastatic infiltration. In this report, we describe an advanced presentation of human alveolar echinococcosis mimicking metastatic malignancy...

Human cystic echinococcosis, an endemic zoonosis in Algeria, is caused by larvae of the cestode Echinococcus granulosus. Parasitic modulation of the immune response allows E. granulosus to persist in intermediate hosts. Previous in vitro and in vivo immunological studies have shown differences in host immune responses according to the status and location of the hydatid cysts in the body. In this study, a proteomic analysis of human hydatid fluids was performed to identify the proteins in hydatid cyst fluids...

Cystic echinococcosis is an important zoonotic disease; it has serious impacts on animals as well as human health throughout the world. Genotypic characterization of Echinocossus granulosus (E. granulosus) in buffaloes has not been addressed in Pakistan. Therefore, the present study was conducted to evaluate the incidence and genotypic characterization of bovine E. granulosus. Out of 832 buffaloes examined, 112 (13.46%) were found infected. The favorable site for hydatid cyst development was liver (8.65%) followed by lungs (4...

MicroRNAs (miRNAs), a class of small non-coding RNAs, are key regulators of gene expression at post-transcriptional level and play essential roles in biological processes such as development. MiRNAs silence target mRNAs by binding to complementary sequences in the 3'untranslated regions (3'UTRs). The parasitic helminths of the genus Echinococcus are the causative agents of echinococcosis, a zoonotic neglected disease. In previous work, we performed a comprehensive identification and characterization of Echinococcus miRNAs...

Echinococcosis is a cosmopolitan zoonotic parasitic disease caused by infection with the larval stage of tapeworms from the Echinococcus genus, most commonly Echinococcus granulosus. According to WHO, more than 1 million people are affected by hydatid disease at any time.1 About 10% of the annual cases are not officially diagnosed.2 In humans, the disease is characterized by development of three-layered cysts. The cysts develop primarily in the liver and the lungs, but can also affect any other organ due to the spreading of the oncospheres...

The larval stage of Echinococcus granulosus causes cystic echinococcosis (CE), a neglected tropical disease that leads to morbidity and mortality in humans and livestock worldwide. Here, we identified and characterized dihydrofolate reductase (Eg-DHFR) from E. granulosus, and evaluated its potential as a diagnostic antigen for sheep CE. Comparison between mammalian (host) DHFR and Eg-DHFR indicates that 45.7% of the 35 active site residues are different. Immunolocalisation analysis showed that native Eg-DHFR was widely distributed in all life-cycle stages of E...

Cardiac echinococcosis is rare. Its spontaneous course is serious because of the risk of rupture. Its clinical manifestations are variable, often latent and misleading. The diagnosis is sometimes referred to by chest radiography. It is much facilitated by non-invasive imaging techniques in particular transesophageal and transthoracic echocardiography, CT scan and magnetic resonance imaging. The latter through a morphological and topographical analysis accurate diagnosis of hydatid cyst and its relationship to cardiac muscle and surrounding tissue...

The World Health Organization (WHO) treatment protocols for cystic echinococcosis (CE) are based on the standardized ultrasound (US) classification. This study examined whether the classification reflected the natural history of CE in untreated and albendazole-treated patients. Data were collected during mass US screenings in CE endemic regions among transhumant populations, the Turkana and Berber peoples of Kenya and Morocco. Cysts were classified using the WHO classification. Patient records occurring prior to treatment, and after albendazole administration, were selected...

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)...

Cystic echinococcosis (CE) is a chronic and complex zoonotic disease. Information on the mechanisms involved in parasite establishment, growth and persistence remain limited. These may be modulated by a crosstalk between extracellular vesicles (EVs). EVs including exosomes and microvesicles are able to carry developmental signaling proteins which coordinate growth and establishment of several parasites. Here, an exosome enriched EV fraction was isolated from hydatid fluid (HF) of fertile sheep cysts. A proteomic analysis of this fraction identified a number of parasite-derived vesicle-membrane associated proteins as well as cytosolic proteins...
