A longitudinal molecular study of the ecology of malaria infections in free-ranging mandrills
In this study, we evaluated the determinants, temporal changes and physiological correlates of Plasmodium infections in a large natural population of mandrills (Mandrillus sphinx). Over six consecutive years, we obtained detailed parasitological and physiological data from 100 male and female mandrills of all ages. The probability of infection by Plasmodium gonderi and P. mandrilli was elevated (ca. 40%) but most infections were chronical and dynamic, with several cases of parasite switching and clearance. Positive co-infections also occurred between both parasites. Individual age and sex influenced the probability of infe...

Morphological and molecular identification of epibiontic sessilid Epistylis semiciculus n. sp. (cciliophora, Peritrichia) from Procambarus clarkia (Crustacea, Decapoda) in China
This study investigates sessilid diversity in Hubei Province, China in 2016. Procambarus clarkia pereopods were covered by two sessilid morphotypes in April and May, and the gills were adhered by one of these two morphotypes (morphotype I) in January. Identifying the two morphotypes according to their morphological characters through live observations and protargol-stained method is difficult. Both morphotypes show almost identical morphological characteristics: zooids present vase-shaped, the length-to-width ratio is 2:1, the semicircle-shaped peristomial disk is evidently above the peristomial lip, single contractile vac...

In this study, we genetically measured the prevalence of two endoparasite taxa, eimerians and cestodes, in 372 faecal samples from collared lemmings, over a five year period and across three distant sites in Northeast Greenland. Prevalence of cestodes was low (2.7% over all sites and years) and this taxon was only found at one site (although in 4 out of 5 years) in adult hosts. By contrast, we found high prevalence for eimerians (77.7% over all sites and years), which occurred at all sites, in every year, for both age classes (at the Hochstetter Forland site where both adult and juvenile faeces were collected) and regardle...

We report the discovery of Trichinella pseudospiralis (T4), a non-encapsulated species, in a wolverine (Gulo gulo) from the Northwest Territories of Canada. This parasite has been previously reported elsewhere from both mammals and carnivorous birds, but our findings represent new host and geographic records for T. pseudospiralis. Multiplex PCR and sequencing of fragments of Cytochrome Oxidase Subunit I (COI) and D3 rDNA confirmed the identification. Phylogenetically, Canadian isolates linked with each other and others derived from Palearctic or Neotropical regions, but not elsewhere in the Nearctic (continental USA). We s...

A review of sarcoptic mange in North American wildlife
Publication date: Available online 13 June 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Kevin D. Niedringhaus, Justin D. Brown, Kellyn M. Sweeley, Michael J. YabsleyAbstractThe “itch mite” or “mange mite”, Sarcoptes scabiei, causes scabies in humans and sarcoptic mange in domestic and free-ranging animals. This mite has a wide host range due to its ability to adapt to new hosts and has been spread across the globe presumably through human expansion. While disease caused by S. scabiei has been very well-studied in humans and domestic animals, there are still nu...

“Parasite-wildlife interaction in a changing world: Vector–borne diseases as example”
Publication date: Available online 12 June 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Annapaola Rizzoli, Valentina Tagliapietra, Francesca Cagnacci, Giovanni Marini, Daniele Arnoldi, Fausta Rosso, Roberto RosàAbstractIn the great acceleration phase of the Anthropocene, changes in climate, land use and biodiversity are considered among the most important drivers of modifications in parasites-host interaction and wildlife zoonotic disease emergence. In the case of vector-borne diseases, changes in vector-host interaction require a continuous monitoring since this parameter con...

Pathobiology and first report of larval nematodes (ascaridomorpha sp.) infecting freshwater mussels (villosa nebulosa, unionidae), including an inventory of nematode infections in freshwater and marine bivalves
Publication date: Available online 13 June 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Andrew McElwain, Micah B. Warren, Felipe B. Pereira, Steven P. Ksepka, Stephen A. BullardAbstractLittle information is available on host-parasite relationships between bivalves and larval nematodes. Herein, we describe larvae (L2) of a nematode (Ascaridomorpha sp.) infecting the foot, intestine, and mantle of a freshwater mussel (Alabama rainbow, Villosa nebulosa [Conrad, 1834]) and detail histopathological changes to infected tissues. A total of 43 mussels from the South Fork of Terrapin Creek, A...

Morphological and molecular characterization of adults and larvae of crassicauda spp. (Nematoda: Spirurida) from mediterranean fin whales Balaenoptera physalus (linnaeus, 1758)
Publication date: Available online 7 June 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): F. Marcer, E. Negrisolo, G. Franzo, C. Tessarin, M. Pietrobelli, E. MarchioriAbstractCrassicauda boopis is known to infect the kidneys and vascular system of mysticetes included Balaenoptera physalus and has been recently reported in Mediterranean waters. Identification at the species level relies on the observation of morphological features of the adult parasites, but field conditions during necropsy and the massive reaction of the host's immune system often prevent optimal conservation of the ext...

Anisakis Nematodes in Fish and Shellfish- from infection to allergies
Publication date: Available online 6 June 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Ibukun E. Aibinu, Peter M. Smooker, Andreas L. LopataAbstractAnisakidosis is a zoonotic parasitosis induced by members of the family Anisakidae. The anisakid genera includes Anisakis, Pseudoterranova, Hysterothylacium and Contracaecum. The final definitive hosts of these nematodes are marine mammals with a complex life cycle. These nematode parasites use different crustaceans and fish species as intermediate or paratenic hosts and humans are accidental hosts. Human anisakiasis, the infections cause...

Reguera-Gomez, M.A. Valero, C. CutillasAbstractTrichuris trichiura is a nematode considered as the whipworm present in humans and primates. The systematics of the genus Trichuris is complex. Morphological studies of Trichuris isolated from primates and humans conclude that the species infecting these hosts is the same. Furthermore, numerous molecular studies have been carried out so far to discriminate parasite species ...
