epidemiology of classical swine fever in sardinia: a serological survey of wild boar and comparison with african swine fever. | a serological survey was carried out to establish the distribution of classical swine fever among wild boar in sardinia, where that disease and african swine fever have been endemic in free-ranging domestic pigs and wild boar living in the mountainous areas of the province of nuoro for several years. blood samples were collected from 4752 wild boar shot during the period december 1988 to january 1992. an overall prevalence of 11 per cent was observed and the almost constant rate of about 9.8 per ... | 1994 | 8171792 |
classical swine fever in sardinia: epidemiology of recent outbreaks. | a variable region of the gene encoding the major glycoprotein (e2) of classical swine fever virus (csfv) was sequenced from 12 sardinian isolates which had been obtained from three geographically distinct regions of the island. phylogenetic analysis of these viruses and others characterized in previous studies [1, 2] indicated that (a) the sardinian viruses were all members of the common european subgroup 2.3 and were clearly distinct from live vaccines recently used in this area; (b) they could ... | 1999 | 10459661 |
molecular epidemiology of classical swine fever in italy. | to gain an insight into the molecular epidemiology of classical swine fever (csf) in italy, virus isolates originating from outbreaks that occurred between 1985 and 2000 in wild boar or in domestic pigs in mainland italy and in sardinia were analysed by genetic typing. for this, a fragment (190 nucleotides) of the e2 glycoprotein gene was sequenced and phylogenetic analyses were performed, including older italian isolates and isolates from recent outbreaks in europe for comparison. the results s ... | 2001 | 11574170 |
the birth of a trichinella britovi focus on the mediterranean island of sardinia (italy). | for 60 years, the islands of the mediterranean basin were considered to be trichinella-free. in april 2005, an outbreak of human trichinellosis due to the consumption of infected pork involved 11 persons in the villages of orgosolo and lanusei (nuoro province) on the island of sardinia (italy). we conducted an investigation to identify free-range and backyard pigs and other humans with trichinella infection in the area of the 2005 outbreak. we also tested wild animals from various parts of sardi ... | 2009 | 19041178 |
effects of human perturbation on the genetic make-up of an island population: the case of the sardinian wild boar. | game species are often manipulated by human beings, whose activities can deeply affect their genetic make-up and population structure. we focused on a geographically isolated wild boar population (sardinia, italy), which is classified, together with the corsican population, as a separate subspecies (sus scrofa meridionalis). two hundred and ten wild boars collected across sardinia were analysed with a set of 10 microsatellites and compared with 296 reference genotypes from continental wild popul ... | 2010 | 21179064 |
genetic characterisation of african swine fever viruses from recent and historical outbreaks in sardinia (1978-2009). | three discrete regions of the african swine fever virus (asfv) were analysed in the genomes of a wide range of isolates collected from wild and domestic pigs in sardinia, over a 31-year period (1978-2009). the analysis was conducted by genotyping based on sequence data from three single copy asf genes. the e183l gene encoding the structural protein p54 and part of the gene encoding the p72 protein were used to delineate genotypes, before intra-genotypic resolution of viral relationships by analy ... | 2011 | 21373994 |
genomic diversity and differentiation of a managed island wild boar population. | the evolution of island populations in natural systems is driven by local adaptation and genetic drift. however, evolutionary pathways may be altered by humans in several ways. the wild boar (wb) (sus scrofa) is an iconic game species occurring in several islands, where it has been strongly managed since prehistoric times. we examined genomic diversity at 49 803 single-nucleotide polymorphisms in 99 sardinian wbs and compared them with 196 wild specimens from mainland europe and 105 domestic pig ... | 2015 | 26243137 |
understanding african swine fever infection dynamics in sardinia using a spatially explicit transmission model in domestic pig farms. | african swine fever virus (asfv) has been endemic in sardinia since 1978, resulting in severe losses for local pig producers and creating important problems for the island's veterinary authorities. this study used a spatially explicit stochastic transmission model followed by two regression models to investigate the dynamics of asfv spread amongst domestic pig farms, to identify geographic areas at highest risk and determine the role of different susceptible pig populations (registered domestic ... | 2017 | 28296281 |
a serosurvey for brucellosis in wild boar (sus scrofa) in sardinia, italy. | porcine brucellosis is a zoonotic disease caused by brucella suis and hosted by pigs (sus scrofa). both domestic pigs and wild boars are affected. we measured the prevalence of antibody to brucella spp. in wild boars in sardinia, italy. during 1 november 2009 to 31 january 2010, we collected 570 serum samples from legally hunted wild boars and tested them using a commercial competitive enzyme-linked immunosorbent assay. sex and age class of the sampled wild boars were also recorded. thirty-five ... | 2015 | 26267463 |
brucella suis infection in domestic pigs in sardinia (italy). | during a 4-year (2007-2010) survey, the presence of brucella suis infection in domestic pigs in sardinia was investigated. serum samples were collected from breeding pigs located on 108 commercial farms with documented reproductive problems and analysed using the rose bengal (rbt) and complement fixation (cft) tests for screening and confirmation of brucella, respectively. of the 1251 serum samples analysed by rbt, 406 sera, originating from 36 farms, were positive for b. suis. cft was positive ... | 2015 | 25530227 |
molecular epizootiology and diagnosis of porcine babesiosis in sardinia, italy. | the recent characterization of the 18s ribosomal rna (rrna) of a pathogenic babesia species in a domestic sow paved the way for establishing diagnostic and epidemiological tools for porcine babesiosis. here, we developed the first specific babesia sp. suis pcr, and we applied this test to a panel of samples collected from animals living in a typical mediterranean environment (sardinia, italy), including domestic pigs, wild boars, and ticks. in domestic pigs, pcr coupled with sequencing revealed ... | 2014 | 25325315 |
like a pig out of water: seaborne spread of domestic pigs in southern italy and sardinia during the bronze and iron ages. | southern italy has a long history of human occupation and passage of different cultures since the early holocene. repeated, ancient introductions of pigs in several geographic areas in europe make it difficult to understand pig translocation and domestication in italy. the archeozoological record may provide fundamental information on this, hence shedding light on peopling and on trading among different ancient cultures in the mediterranean. yet, because of the scanty nature of the fossil record ... | 2017 | 27649620 |
why is african swine fever still present in sardinia? | african swine fever (asf) is an infectious disease of swine that has been present in sardinia since 1978. soon after introduction of the disease, several control and eradication programmes were established with limited success. some researchers attributed the persistence of the disease in central and eastern areas to certain socio-economic factors, the existence of some local and traditional farming practices (i.e., unregistered free-ranging pigs known as brado animals) and the high density of w ... | 2017 | 29027378 |
spatio-temporal analysis of african swine fever in sardinia (2012-2014): trends in domestic pigs and wild boar. | african swine fever (asf) is a notifiable viral disease affecting domestic pigs and wild boars that has been endemic in sardinia since 1978. several risk factors complicate the control of asf in sardinia: generally poor level of biosecurity, traditional breeding practices, illegal behaviour in movements and feeding of pigs, and sporadic occurrence of long-term carriers. a previous study describes the disease in sardinia during 1978-2013. the aim of this study was to gain more in-depth knowledge ... | 2017 | 26392004 |
