You are kindly invited to publish your work in the new Special Issue of Pathogens (IF = 3.405) which is focused on Echinococcus spp. and echinococcosis. Echinococcus (mainly E. multilocularis and E. granulosus s.l.) is widely distributed and one of the most dangerous zoonotic parasites in the world. Epidemiological studies on the occurrence of this infection in humans as well as in animals that may be a source of infection for people are extremely important. Therefore, a lot of investigations on the development and improvement of diagnostic methods have been carried out. Moreover, many different programs of monitoring and control of echinococcosis in human and animal hosts have been elaborated and applied. What is more, all of these actions are supported by fast development of genetic studies concerning this tapeworm. This Special Issue gives the opportunity to publish research papers and reviews that cover this wide thematic scope.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.

Title: The Molecular Epidemiology of Echinococcus infections
Authors: Andrew Thompson
Affiliation: School of Veterinary and Life Sciences Murdoch University Murdoch WA 6150 Australia
Abstract: Molecular epidemiology is the application of molecular tools to determine the causation of disease. With infectious diseases, such as echinococcosis, this applies to identifying and characterising the aetiological agents and elucidating host range. Such an approach has been very successful with the causative agents of echinococcosis, species of Echinococcus, initially by providing a workable and practical taxonomy and subsequently determining transmission patterns in endemic areas. This review summarises the taxonomy and nomenclature of species of Echinococcus and provides an overview of the ecology of Echinococcus transmission, particularly in areas where more than one species of Echinococcus is maintained in cycles of transmission that may interact. Emphasis is given to emerging issues in the epidemiology of echinococcosis particularly regarding wildlife and urbanisation.

Abstract: Cystic echinococcosis (CE) caused by the cestode Echinococcus granulosus sensu lato is a worldwide zoonosis and E. granulosus sensu stricto (s.s.) is the most common species associated with animal and human pathology. The objective of this study was to obtain a better understanding of the CE infection in livestock and humans from very low and high endemic areas − France and Tunisia − by studying the genetic diversity of E. granulosus s.s. at the intra-individual host level. This genetic diversity was studied using EgSca6 and EgSca11 microsatellites profiles in 93 sheep from France and Tunisia, 12 cattle and 31 children from Tunisia only, all infected by multiple CE cysts (2 to 10 cysts). Overall, 96% of sheep, 92% of cattle and 48% of children had at least two cysts with different microsatellites profiles. Inversely, 35% of sheep, 17% of cattle and 65% of children had at least two cysts with the same microsatellites profiles. The genotyping results of the CE samples highlights a high and similar genetic diversity in France and Tunisia, suggesting that the probability of being successively infected by CE of the same microsatellite profile was rare in both countries. Therefore, our results suggest that in rare cases, several eggs of the same microsatellite profile, from two to seven in our data, can be ingested simultaneously in a single infection event and develop into several cysts in livestock and children. They also indicate that multiple infection events are frequent in livestock, even in a low endemic country such as France, and are less frequent but not negligible in children in a high endemic country such as Tunisia. Moreover, it’s the first time that genetic evidence of secondary CE is given. Further studies are needed to better assess the pattern of infection events in livestock and humans, especially by studying the genetic diversity of adult worm in definitive hosts.
