New article with videos “Mate locating and access behaviour of the parasitic pea crab, Nepinnotheres novaezelandiae, an important parasite of the mussel Perna canaliculus”

Did you ever wonder why you occasionally find small pea crabs in your mussels?

In their article, Oliver Trottier and Andrew G. Jeffs explain when, why and how the male pea crabs get into the mussel. When? At night. Why? Because they are searching for a female, of course! How? By gently stroking the mantle edge of the mussel, thus causing it to open.

This article is illustrated with 3 infrared videos, showing the different steps.


“Pea crabs are globally ubiquitous symbionts in the marine environment that cause serious economic impact in the aquaculture production of several major bivalve species. However, little is known about their host-parasite interactions, especially the mating behaviour of these parasites that could prove useful for controlling their infestation in aquaculture. In this study, the mate location behaviour of male New Zealand pea crabs, Nepinnotheres novaezelandiae (Filhol, 1885), was observed when dwelling in its preferred host, the commercially important green-lipped mussel, Perna canaliculus.”

Meet Alessandro Massolo and Stefano Liccioli, authors in Parasite, on Canadian TV

Alessandro Massolo and Stefano Liccioli are the authors of the review "Echinococcus multilocularis in North America: the great unknown", which was published in the topical volume of Parasite "Innovation for the Management of Echinococcosis".

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. In their review, they present the available data on E. multilocularis infections in wild and domestic animals and humans in North America and emphasize the lack of knowledge on the distribution of the parasite in wild and domestic hosts. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred.

New review article “An update on Acanthamoeba keratitis: diagnosis, pathogenesis and treatment”, by Jacob Lorenzo-Morales, Naveed A. Khan and Julia Walochnik (February 2015)

At the occasion of the ICOPA XIII congress, which was held in August 2014 in Mexico, selected authors were invited to publish papers in the Open Access peer-reviewed journal Parasite. A review on Acanthamoeba keratitis was chosen.

This high-quality 20-page review, with several original figures, deals with a worldwide increase in parasitic human infection. The three authors, Jacob Lorenzo-Morales (University of La Laguna, Tenerife, Spain), Naveed A. Khan (Aga Khan University, Karachi, Pakistan) and Julia Walochnik (Medical University of Vienna, Austria) present their current understanding on eye infections by amoebas, based on their long experience as leading scientists for this parasitic disease.

Free-living amoebae of the genus Acanthamoeba are causal agents of a severe sight-threatening infection of the cornea known as Acanthamoeba keratitis. The number of reported cases worldwide is increasing every year, mostly in contact lens wearers. Acanthamoeba keratitis has remained significant despite the advances in antimicrobial chemotherapy and supportive care. Altogether, this review may serve as the milestone for developing an effective solution for the prevention, control and treatment of Acanthamoeba infections.

Overview of the diagnostic procedure for Acanthamoeba keratitis.

Abstracts in four languages for new paper for the prevention of echinococcosis in remote communities (December 2014)

Proper disposal of carcasses and offal after home slaughter is difficult in poor and remote communities and therefore dogs readily have access to hydatid cysts containing offal from livestock, thus completing the parasite cycle of the tapeworm Echinococcus granulosus and putting communities at risk of cystic echinococcosis.

The new paper by Li et al. proposes a very simple way to eliminate this threat to public health: boiling livers and lungs for 30 minutes. This could be an efficient and cheap complement to other veterinary public health operations to control cystic echinococcosis.

This paper is part of the topical issue of Parasite “Innovation for the Management of Echinococcosis.” Invited editors: Dominique A. Vuitton, Laurence Millon, Bruno Gottstein and Patrick Giraudoux.

Because this paper contains information that could be useful not only to specialists, but also to physicians, veterinarians and the general public in countries infested with echinococcosis, including remote communities, the abstract of the paper is published in four languages: English, French, Chinese and Arabic. The paper is also illustrated by three full-page illustrations. Since the paper is fully open access and free to download, we expect it to be read by a wide audience in infested countries.

Boiling sheep liver or lung for 30 minutes is necessary and sufficient to kill Echinococcus granulosus protoscoleces in hydatid cysts

The new Impact Factor of Parasite (September 2014)

What is the reason for this?

Simply because the Impact Factor is calculated two to three years after papers are published. What we see now with the “2013 Impact Factor” (published in 2014) are the results for citations of papers published in 2011 and 2012. See Table:

YearImpact FactorPublishedBasis of Impact Factor
IF 20121.116June 2013Citations in 2012 of papers published in 2010 and 2011
(Print edition)
IF 20130.822July 2014Citations in 2013 of papers published in 2011 and 2012

IF 2014 2015Citations in 2014 of papers published in 2012 and 2013
(50% print edition, 50% new online edition)
IF 20152016Citations in 2015 of papers published in 2013 and 2014
(100% new online edition)

Red: new online edition of Parasite.

What does this mean for Parasite?

In 2012, the French Society of Parasitology, owner of Parasite, decided to change the publisher (now EDPS), to nominate a new Editorial Board, and to replace the former print version with a new open-access online-only edition. Does the new lower Impact Factor mean that these were not the right choices? Certainly not. The new IF shows that we were right in making all these changes, because what we see now with the lower IF is the consequence of the failure of the print edition in 2011 and 2012.

Is the IF likely to improve?

We have evidence that papers in the new online edition are already cited more than their equivalents in the former print edition. As of 15 September 2014, three papers published in 2013 have already scored respectively 7, 5 and 4 citations in ISI, and many have been cited more than once (i.e. they already provide an Impact Factor higher than 1). However, in 2015 the Impact Factor will still bear the weight of the last year of the print version (see Table).

Is Parasite a better journal than before?

We believe so, and we are striving to achieve more. Papers in Parasite are immediately indexed in PubMed, often the same day they are published. All papers are available from the website of the journal and from PubMed Central and Europe PubMed Central. Several papers have been viewed more than 1,000 times. All papers are subject to a strict peer-review process, and our rejection rate is about 50%. More than 100 new manuscripts have already been submitted this year (September 2014), by scientists from all over the world.

Thank you to all our authors and reviewers. We work to honour the aim of Parasite: “An international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology”.

A review of Cutaneous Leishmaniasis in North Africa, by Karim Aoun and Aida Bouratbine (Institut Pasteur, Tunis, Tunisia)

Geographical distribution of cutaneous leishmaniasis cases due to L. infantum, L. major, and L. tropica in North African countries.

In North African countries, cutaneous leishmaniasis transmission has been increasing since the 80s, with a significant increase in the incidence of cases and a spread of the geographical distribution. Cutaneous leishmaniasis currently represents a major public health problem with a productivity gap and an impediment for development, which results in dramatic socioeconomic and psycho-sanitary impacts. The review includes a map of the occurrence of the three Leishmania species involved in Algeria, Libya, Morocco, Tunisia and Egypt.


The review is in English with English, French and Arabic abstracts. As Parasite is an open-access journal under a Creative Commons licence, the text and the figures can be freely re-used, provided that the source is correctly cited.
