Until there is an effective implementation of COVID-19 vaccination program, a robust testing strategy, along with prevention measures, will continue to be the most viable way control disease spread. Such strategy should rely on disparate diagnostic tests prevent slowdown in due lack materials and reagents imposed by supply chain problems, which happened at beginning pandemic. In this study, we have established single-tube test based RT-LAMP that enables visual detection less than 100 viral...
Since 2016, A(H5Nx) high pathogenic avian influenza (HPAI) virus of clade 2.3.4.4b has become one the most serious global threats not only to wild and domestic birds, but also public health. In recent years, important changes in ecology, epidemiology, evolution this have been reported, with an unprecedented diffusion variety affected birds mammalian species. After two consecutive devastating epidemic waves Europe 2020-2021 2021-2022, second recognized as largest epidemics recorded so far,...
The very neutron-rich oxygen isotopes ${}^{25}$O and ${}^{26}$O are investigated experimentally theoretically. unbound states populated in an experiment performed at the R3B-LAND setup GSI via proton-knockout reactions from ${}^{26}$F ${}^{27}$F relativistic energies around 442 414 MeV/nucleon, respectively. From kinematically complete measurement of decay into ${}^{24}$O plus one or two neutrons, ground-state energy width determined, upper limits for lifetime extracted. In addition, results...
The exposure of wild carnivores to viral pathogens, with emphasis on parvovirus (CPV/FPLV), was assessed based the molecular screening tissue samples from 128 hunted or accidentally road-killed animals collected in Portugal 2008 2011, including Egyptian mongoose (Herpestes ichneumon, n = 99), red fox (Vulpes vulpes, 19), stone marten (Martes foina, 3), common genet (Genetta genetta, 3) and Eurasian badger (Meles meles, 4). A high prevalence DNA (63%) detected among all surveyed species,...
Quasifree one-proton knockout reactions have been employed in inverse kinematics for a systematic study of the structure stable and exotic oxygen isotopes at ${\mathrm{R}}^{3}\mathrm{B}/\mathrm{LAND}$ setup with incident beam energies range $300--450\text{ }\mathrm{MeV}/\mathrm{u}$. The isotopic chain offers large variation separation that allows quantitative understanding single-particle strength changing isospin asymmetry. provide complementary approach to intermediate-energy one-nucleon...
Abstract It is unclear whether West Nile virus (WNV) circulates endemically in Portugal. Despite the country’s adequate climate for transmission, Portugal has only reported four human WNV infections so far. We performed a review of WNV-related data (1966–2020), explored mosquito (2016–2019) and land type distributions (1992–2019), used (1981–2019) to estimate transmission suitability Serological molecular evidence circulation from animals vectors was largely restricted south. Land...
To isolate and characterize bacteriophages, to evaluate its lytic performance against avian pathogenic Escherichia coli (APEC) strains with high patterns of antibiotic resistance, in order select phages for a therapeutic product treat colibacillosis chickens.Bacteriophages were isolated from poultry sewage tested 148 O-serotyped APEC strains. The morphological characterization the bacteriophages was made by transmission electronic microscopy (TEM) observations genetic comparison between DNA...
The first official case of bluetongue virus serotype 3 (BTV-3) in Portugal was confirmed sheep from the district Évora September 2024. Notably, mortality observed pregnant sheepdogs within affected flocks. This study presents four cases dogs infected with BTV-3 mid-September 2024, all which aborted prior to death. identified by RT-qPCR following initial positive results pan-BTV RT-qPCR. subsequently isolated blood one BHK-21 cells, and a partial sequence vp2 gene obtained. showed 100%...
Birds are natural hosts for numerous zoonotic viral pathogens, including West Nile virus, which is transmitted by mosquitoes. During migration, birds can act as vectors the geographic spread of viruses. WNV endemic in Portugal, causing annual outbreaks, particularly horses. Here, we report first detection an avian strain isolated from a wild bird (Astur gentilis) collected Portugal mid-September 2024. Phylogenetic and phylogeographic analyses were conducted to trace virus’s origin potential...
Abstract Bagaza virus emerged in Spain 2010 and was not reported other countries Europe until 2021, when the detected by molecular methods a corn bunting several red-legged partridges Portugal. Sequencing revealed high similarity between 2021 strains from Portugal Spain.
The quasi-free scattering reactions 11C(p,2p) and 10,11,12C(p,pn) have been studied in inverse kinematics at beam energies of 300–400 MeV/u the R3B-LAND setup. outgoing proton-proton proton-neutron pairs were detected coincidence with reaction fragments kinematically complete measurements. efficiency to detect these has obtained from GEANT4 simulations which tested using 12C(p,2p) 12C(p,pn) reactions. Experimental cross sections momentum distributions compared DWIA calculations based on...
Bagaza virus (BAGV) is a mosquito-borne flavivirus of the family Flaviviridae, genus Orthoflavivirus, Ntaya serocomplex. Like other viruses and Japanese encephalitis serocomplexes, it maintained in nature transmission cycles involving viremic wild bird reservoirs Culex spp. mosquitoes. The susceptibility red-legged partridge, ring-necked pheasant, Himalayan monal common wood pigeon well known. Determining whether species are susceptible to BAGV infection fundamental understanding dynamics...
In September 2024, bluetongue virus serotype 3 (BTV-3) was first identified in Portugal, specifi-cally the Alentejo region (Évora District), using molecular diagnostic methods. The initial case involved a sheep exhibiting severe clinical symptoms, including head oedema, prostration, nasal discharge, and significant respiratory distress. A subsequent documented another from different farm within same district, which presented with high fever (41.5°C), arthritis, ultimately resulting...
This report presents the results of a multiyear (2005 to 2009) study avian influenza virus (AIV) occurrence in wild birds Portugal. A total 5691 samples from belonging 13 different orders were examined. Ninety-three tested positive for AIV by matrix reverse transcriptase-polymerase chain reaction, giving prevalence 1.63%. Twenty-one viruses successfully cultured embryonated chicken eggs, which represent rate viral infectivity 22.6% samples. Nine subtypes haemagglutinin (H1, H3 H7, H9 H11)...
Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute Health early stages COVID-19 epidemic, collaboration with more than 50 laboratories distributed nationwide.By applying recent phylodynamic models that allow integration individual-based travel history, we reconstructed and characterized spatio-temporal dynamics introductions dissemination Portugal.We detected at least 277 independent introductions, mostly from European countries (namely United...
Background: For many years, quasifree scattering reactions in direct kinematics have been extensively used to study the structure of stable nuclei, demonstrating potential this approach. The RB3 collaboration has performed a pilot experiment inverse for C12 beam. results from that constitute first and complete kinematics. This technique lately extended exotic beams investigate evolution shell structure, which attracted much interest due changes if number protons or neutrons is varied....
Background: Odd-odd nuclei, around doubly closed shells, have been extensively used to study proton-neutron interactions. However, the evolution of these interactions as a function binding energy, ultimately when nuclei become unbound, is poorly known. The $^{26}\mathrm{F}$ nucleus, composed deeply bound $\ensuremath{\pi}0{d}_{5/2}$ proton and an unbound $\ensuremath{\nu}0{d}_{3/2}$ neutron on top $^{24}\mathrm{O}$ core, particularly adapted for this purpose. coupling results in...
