“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 contributes in determining the vectorial capacity and consequently infection hazard for humans and animals. Several intrinsic and extrinsic vector, pathogen and host factors affect the vectorial capacity. Among extrinsic factors, changes in vector host abundance and behavior or shift in vector- host preference exert an important role in shaping the spatial and temporal dynamics of vector borne disease emergence. The scope of this review is to highlight how some of such changes modulate the dynamics of two important vector-borne diseases in Europe such as Tick borne encephalitis virus (TBEV) and West Nile virus (WNV). Changes in infection hazard depend on the pattern of tick infestation on the rodent hosts which in turn depends on the variation in tick hosts abundance and behaviour. West Nile Virus (WNV) is nowadays considered the most widespread arthropod-borne...

This study represents the first large scale attempt to gather a long period information on Q fever infection in Greece. The findings of the current study support the fact that Q fever is an important endemic zoonotic disease in Greece and needs increased awareness by clinical physicians and health care system.

LabrunaAbstractA new argasid (Argasidae) tick is herein described based on morphology and molecular data obtained from larvae parasitizing Octodon degus and from ticks collected inside burrows in northern Chile. Unfed laboratory-reared larvae were mounted in slides for morphometrical and morphological analyses. Larvae of Ornithodoros octodontus n. sp. share morphological tr...

Kwak, Chi-Chien Kuo, Ho-Tsung ChuAbstractThe sea snake tick (Amblyomma nitidum) is a host specialist of snakes in the genus Laticauda and is one of the few ticks which could be regarded as semi-marine. Yet despite the attention this species has received due to its bizarre ecology, its distribution remains poorly known as geographic records of its occurrence through the Asia-Pacific are highly fragmentary. For the first time this species is recorded from Taiwan based on specimens collected from the yellow-lipped se...

Humans and monkeys are dead-end hosts for these viruses. Recent trends in epidemiological data suggest both virus incidences are steadily increasing and their geographical distribution expandi...

Authors: Fraenkel S, Salvioni OD, de Arias AR, Arze VP, Rolón M, Ramirez N, Vega Gómez C Abstract The Paraguayan Chaco is an isolated environment with its own unique ecosystem. In this region, Chagas disease remains a health problem. Chagas disease is caused by the parasite Trypanosoma cruzi, and it is primarily transmitted by triatomines. In order to identify the blood meal sources of triatomines, specimens of the vector were collected in residential and residential adjacent areas and the PCR-RFLP method was implemented. Cytochrome b was amplified from the samples and later subjected to digestion wit...

Abstract Hosts that overlap geographically, are less phylogenetically divergent, and/or share similar ecological conditions (e.g., climate, habitat type) are also likely to share parasites. Here we assessed the ectoparasite communities sustained by 3 solitary species of Bathyergidae (Georychus capensis, Bathyergus suillus, and Bathyergus janetta) as well as the endoparasites exploiting G. capensis and compared them with those reported in the literature for other sympatric and parapatric African mole-rat species. In addition to 1 nematode ( Trichuris sp.) and 1 symbiotic ciliate (Meistoma georychi), we collected mi...
