Cardio-pulmonary nematodes of the red fox (Vulpes vulpes) of Sardinia, Italy.

Cardio-pulmonary parasites, such as Angiostrongylus vasorum, Crenosoma vulpis, and Eucoleus aerophilus, pose a significant concern on account of pulmonary and cardiac problems they induce in dogs. While the red fox is known to be a key reservoir host for A. vasorum and may also play a role in transmitting C.

First molecular description of Macracanthorhynchus hirudinaceus in wild boars from Italy with pathomorphological and epidemiological insights.

Macracanthorhynchus hirudinaceus is a zoonotic parasite affecting suids worldwide which are the definitive hosts for this helminth species. Macracanthorhynchus hirudinaceus is of significant economic and management concern due to its pathogenicity, causing intestinal obstruction and perforation in the definitive hosts. Current study is the preliminary investigation from Sardinia, Italy, reporting the pathomorphological findings and molecular characterization of M.

Vector Competence of Italian Populations of for Some Bluetongue Virus Strains Responsible for Recent Northern African and European Outbreaks.

The distribution of Bluetongue virus (BTV) in Europe can be represented by two distinct and interconnected epidemiological systems (episystems), each characterized by different ecological characteristics and vector species. This study investigated the vector competence of Italian populations of and to some representative BTV strains after artificial oral infection. The BTV strains were selected according to their ability to spread to one or both episystems and included BTV-4 ITA, responsible of the recent Italian and French BTV-4 outbreaks; the BTV-2 strain which caused the first BTV incursion in Italy, Corsica, and Balearic Islands; BTV-4 MOR, responsible for the epidemic in Morocco; and BTV-8, the strain which spread through Europe between 2006 and 2008.

Bluetongue virus detection in new species in Sardinia, Italy.

Bluetongue is an infectious disease transmitted by biting midges. is considered the main vector in the Mediterranean basin but other species have been implicated in the Bluetongue virus (BTV) transmission. During 2017, BTV serotype 4 re-occurred in Sardinia causing outbreaks in sheep farms.

Genomic signatures of adaptive introgression from European mouflon into domestic sheep.

Mouflon (Ovis aries musimon) became extinct from mainland Europe after the Neolithic, but remnant populations from the Mediterranean islands of Corsica and Sardinia have been used for reintroductions across Europe since the 19-century. Mouflon x sheep hybrids are larger-bodied than mouflon, potentially showing increased male reproductive success, but little is known about genomic levels of admixture, or about the adaptive significance of introgression between resident mouflon and local sheep breeds. Here we analysed Ovine medium-density SNP array genotypes of 92 mouflon from six geographic regions, along with data from 330 individuals of 16 domestic sheep breeds.

Genetic and pathological characteristics of Cryptococcus gattii and Cryptococcus neoformans var. neoformans from meningoencephalitis in autochthonous goats and mouflons, Sardinia, Italy.

In this study, we examined in Sardinia the brain of 555 autochthonous sheep, 50 goats, and 4 mouflons which were found affected by neurological signs. We found 6 goats and one mouflon with meningoencephalitis caused by Cryptococcus sp. There was no evidence of cryptococcal infections in any of the examined sheep.

Avian influenza and animal health risk: conservation of endemic threatened wild birds in Sardinia Island.

Sardinia is a Mediterranean island with a long geological history, leading to a separation process from continental Europe during the Miocene. As a consequence, in this insular habitat some wild bird species developed endemic forms, some of which are currently threatened. The aim of this study is to evaluate the possible animal health risk associated with a potential avian influenza virus (AIV) circulation in Sardinian wild bird populations.

Wildlife molecular forensics: identification of the Sardinian mouflon using STR profiling and the Bayesian assignment test.

A forensic short tandem repeat (STR) typing test using a population database was developed to investigate an instance of poaching on the protected Sardinian mouflon. The case study involves a suspected poacher found in possession of a carcass, which he claimed was that of a sheep from his flock and had died accidentally. His claim was refuted by the molecular forensic analyses as DNA typing and the Bayesian assignment test revealed the carcass to be mouflon-derived; the genetic profile of the carcass matched also that of additional trace evidence collected by forestry officers at the scene of the kill.

Pathogens and symbionts in ticks: a survey on tick species distribution and presence of tick-transmitted micro-organisms in Sardinia, Italy.

A total of 1485 adult ticks were collected from mammalian hosts in south-eastern Sardinia, Italy, during the years 2007-2008. Ticks were identified and tested by PCR analysis for presence of Rickettsia species of the spotted fever group, Ehrlichia canis, Anaplasma phagocytophilum, Coxiella burnetii, Bartonella species and Leishmania species. Among all tick species examined (Rhipicephalus sanguineus, Rhipicephalus turanicus, Rhipicephalus bursa, Rhipicephalus pusillus, Hyalomma marginatum marginatum, Haemaphysalis sulcata and Dermacentor marginatus), only Hyalomma marginatum marginatum produced negative results.
