| genetic characterisation of porcine circovirus type 2 (pcv2) strains from feral pigs in the brazilian pantanal: an opportunity to reconstruct the history of pcv2 evolution. | since its discovery, porcine circovirus type 2 has emerged as one of the most relevant swine infectious diseases, causing relevant economic losses for the pig industry. while four genotypes were identified, only three (pcv2a, pcv2b and pcv2d) are currently circulating and display a worldwide distribution. another genotype, pcv2c, has been described only once in danish archive samples collected between 1980 and 1990. in addition to commercial pigs, pcv2 has been demonstrated to infect wild boars ... | 2015 | 25975522 |
| feral pigs as hosts for amblyomma sculptum (acari: ixodidae) populations in the pantanal, mato grosso do sul, brazil. | the pantanal in brazil is the largest floodplain of the world. this ecosystem, rich in wildlife, has a large feral pig population. such a large host biomass must have a strong influence on the parasite fauna. in this work, we evaluated the role of feral pigs in the maintenance of amblyomma sculptum (formerly amblyomma cajennense), the most prevalent tick species in the pantanal. tick infestations were evaluated on 243 feral pigs and their environment. the suitability of domestic pigs, representi ... | 2014 | 25037743 |
| serological and molecular investigation of the prevalence of aujeszky's disease in feral swine (sus scrofa) in the subregions of the pantanal wetland, brazil. | the feral swine (fs) originated from the domestic pig and is present throughout the brazilian wetland plain (the pantanal). aujeszky's disease (ad) was first serologically confirmed in the state of mato grosso do sul (ms) in 2001; however, there was no viral confirmation. the aim of this study was to investigate antibodies against-suhv-1 in the sera of feral swine in the studied areas, detect suhv-1 through pcr and classify the viral genome. among the 218 animals sampled, 186 were analyzed by el ... | 2013 | 23639473 |
