Evidence of avian poxvirus and papillomavirus infection in Gyps fulvusin Italy
No full textThe identification of avian poxvirus and avian papillomavirus associated with cutaneous lesions in griffon vultures (Gypsfulvus) by histopathology, electron microscopy and PCR analysis is reported. Sequence analysis of the fpv140 gene revealed99% identity to two poxviruses obtained from a white-tailed sea eagle (Haliaeetus albicilla) and a common buzzard (Buteobuteo). Partial sequence of the papillomavirus L1 gene showed sequence similarity to papillomavirus LI genes from Africangrey parrot (Psittacus erithacus) (69% identity), duck (Anas platyrhynchos) (68% identity), and yellow-necked francolin(Francolinus leucoscepus) (66% identity). To date, this is the first identification of avian poxvirus and papillomavirus ingriffon vultures and the first evidence of infection of both viruses in live wild birds

Avian hepatitis E virus is widespread among chickens in Polandand belongs to genotype 2
No full textAbstractBig liver and spleen disease, caused by avian hepatitis E virus, has been reported in Poland, but the prevalence of the virushas not yet been investigated. In this study, 1034 serum samples from 57 breeder broiler and laying hen flocks were screenedfor the presence of anti-aHEV antibodies. In a random serology study, 56.1% of flocks were positive. Seroprevalence washigher in laying hen flocks than in broiler breeder flocks. Phylogenetic analysis of partial ORF1 and ORF2 sequences revealedthat all Polish isolates belonged to genotype 2. This is the first time this genotype has been detected in Central Europe
Both type I and type III interferons are required to restrict measlesvirus growth in lung epithelial cells
No full textAbstractMeasles virus (MeV) first infects immune cells in the respiratory tract of a human host, spreads to lymphoid organs throughoutthe body, and finally enters and grows in respiratory epithelial cells before being released and transmitted to the nexthost. Thus, efficient growth in respiratory epithelial cells is important for the person-to-person transmission of MeV. Uponviral entry, host cells detect viral nucleic acids and produce interferons (IFNs) to control viral growth. Type I (IFN-?/?)and type III (IFN-?) IFNs have largely common induction and signaling mechanisms and stimulate expression of similartarget genes but utilize distinct receptors. To determine the relative contributions of type I and type III IFNs to the controlof MeV growth in epithelial cells, we examined the growth of MeV and that of its mutants lacking either type I or type IIIIFN receptor in the human lung epithelial cell line H358. Our results revealed that both type I and type III IFNs are requiredto restrict MeV growth in H358 cells and that the induction of type III as well as type I IFNs was increased in the absenceof the MeV nonstructural V protein
Towardsacooperativesecuritysystemformobile-health applications
No full textAbstract Mobilehealth(m-health)systemarchitecturesaretypicallybasedonmobile and wireless communications, and use mobile devices with data exchange supported by Web Services (WS). Although m-health systems offer mobility as a potential and precious resource they also present several challenged issues and constraints, such as, battery and storage capacity, broadcast constraints, interferences, disconnections, noises, limited bandwidths, and network delays. Furthermore, constant mobility and often-required Internet connectivity also exposes and compromises the privacy and con?dentiality of the m-health system information. This paper proposes a novel dat
Discovery of a novel Tymoviridae?like virus in mosquitoes from Mexico
No full textAbstractA novel Tymoviridae-like virus, designated Ek Balam virus, was isolated from male Culex quinquefasciatus mosquitoescollected in Yucatan, Mexico. The genome was fully sequenced and shown to have no more than 69% nt sequence identityto its closest known relative. Mosquito cells were permissive to Ek Balam virus replication, but mammalian and avian cellswere refractory, suggesting that vertebrates are not involved in the maintenance of the virus in nature
