Epidemiology of echinococcosis in Iran: a systematic review and meta-analysis

Echinococcosis is a zoonotic disease caused by the larval stages of taeniid cestodes of the genus Echinococcus. The two major types of infection in humans are cystic echinococcosis (CE) or hydatidosis and alveola...

lli A Abstract The zoonotic tapeworm Echinococcus granulosus sensu lato (s.l.) represents a species complex encompassing multiple causative agents of cystic echinococcosis, a neglected tropical disease affecting more than one million people in the world. At least eight genotypes, grouped in five species, are currently recognized within this species complex, and they differ in terms of relative public health impact. Here we present a molecular method that first identifies the common E. granulosus sensu stricto (s.s.) (genotypes G1 and G3) based on a PCR-RFLP assay, and can further identify the remaining species bas...

Abstract Cystic echinococcosis (CE) is a zoonotic disease that occurs in humans and ungulates due to infection with the larval stage of the taeniid cestode Echinococcus granulosus sensu lato. It has been estimated that approximately one million people are infected annually, resulting in US$3 billion in human and livestock-associated direct and indirect losses per year. CE is a serious public health concern in many parts of the world, including Pakistan. This review discusses the causative agent as well as the epidemiology, diagnosis, and treatment of CE in Pakistan. PMID: 32956637 [PubMed - as supplied by publisher]

The objective of this component was to implement, and then evaluate an Integrated Control Intervention (ICI) against three dog transmitted zoonoses, namely rabies, visceral leishmaniasis, and cystic echinococcosis. This was undertaken in Sidi Kacem Province (northwestern Morocco) where 22 control and 22 treated douars (villages) were randomly allocated to two control and one evaluation interventions over a period of 13 months. Across the 44 douars, an overall total of 6922 dogs were registered, 4519 were vaccinated against rabies, and 2885 persons attended the complementary health education campaigns; whereas, within the 2...

by Andrew Lawson, R Boaz III, A. Corber án-Vallet, Marcos Arezo, Edmundo Larrieu, Marco A. Vigilato, Victor J. Del Rio Vilas The analysis of zoonotic disease risk requires tshe consideration of both human and animal geo-referenced disease incidence data. Here we show an application of joint Bayesian analyses to the study of echinococcosis granulosus (EG) in the province of Rio Negro, Argentina. We focus on merging passi ve and active surveillance data sources of animal and human EG cases using joint Bayesian spatial and spatio-temporal models. While similar spatial clustering and temporal trending was apparent, the...

Abstract Alveolar echinococcosis (AE) is a rare zoonotic disease caused by the larval stage of Echinococcus multilocularis. Despite its low world-wide prevalence, this disease shows differences in the regional distribution of cases. In the present cohort study, we analyse the distribution of AE according to environmental and geographical factors in Germany. We identified the place of residence of 591 cases of AE from the national database for AE, and georeferenced these localities in the Universal Transverse Mercator coordinate system. Data on elevation, air temperature, precipitation height and land cover were ma...

This study aims to assess the level of knowledge about zoonoses, specifically echinococcosis and toxocariasis, among cat/dog owners and non-pet owners in Greece. Multiple-choice questionnaires were designed to obtain data regarding the knowledge of pet and non-pet owners on echinococcosis and toxocariasis, including signs and symptoms of these zoonoses, ways of transmission and precautions that need to be taken into account in order to avoid it. A total of 185 questionnaires were retrieved and data was expressed as absolute (Ν) and relative frequencies (%). Associations between pet ownership, residence and outcome v...

In conclusion, for the first time, we identified the ncRNAs profiles in PSC–ELVs and HF–ELVs that might be involved in host immunity and pathogenesis, and enriched the ncRNAs data of E. granulosus. These results provided valuable resources for further analysis of the regulatory potential of ncRNAs, especially miRNAs, in both types of ELVs at the parasite–host interface.

In this study, the protoscoleces (PSCs) in the encystation process were analyzed by high-throughput RNA sequencing. A total of 32,401 transcripts and 14,903 cDNAs revealed numbers of new genes and transcripts, stage-specific genes, and differently expressed genes. Genes encoding proteins involved in signaling pathways, such as putative G-protein coupled receptor, tyrosine kinases, and serine/threonine protein kinase, were predominantly up-regulated during the encystation process. Antioxidant enzymes included cytochrome c oxidase, thioredoxin glutathione, and glutathione peroxidase were a high expression level. Intriguingly...

Conclusions: Echinococcosis and fasciolosis were very common with one out of five animals slaughtered infected. This is of public health concern and needs urgent multi-sectorial efforts from stakeholders at the national and regional level for control of these diseases. One health program approaches may warrant the control of transmission to humans.
