- Assessing gastrointestinal parasites of Iberian wolves in northwestern Spain through environmental fecal samplesPublication . Nunes, Inês Emanuel Lopes; Mateus, Teresa Susana LetraThe major threats to the Iberian Wolf (Canis lupus signatus) include habitat degradation and fragmentation due to the expansion of human occupation, ultimate changes to agricultural practices and territory management, serious decline of preys and poaching. But it is known that parasitic infections severely influence wildlife populations, Iberian Wolf being no exception. The proximity between wolf and humans may be a threat to Public Health once zoonotic pathogens can spread from wolves to human and contrariwise, especially because of environmental contamination. The aim of this study is to evaluate the prevalence and diversity of gastrointestinal parasites among Iberian wolves in northwestern Spain. The use of fecal samples is an excellent alternative to the studies conducted before in the Iberian Peninsula, based on data collected post mortem. Therefore, fecal samples were collected directly from the environment (n=398) in predetermined transects in Los Ancares (n=249), Picos de Europa (n=129) and Costa da Morte (n=20) between July and October 2012 and were analyzed using Willis method. Two hundred and one samples were also analyzed using Ritchie method. The overall prevalence was 65.33%. At least thirteen different parasites have been identified with prevalence ranging between 0.25-43.97%: Trichuris spp. (43.97%), Ancylostomatidae (21.60%), Taeniidae (7.54%), Toxocara spp. (7.54%), Capillaria spp. (5.53%), Dicrocoelium dendriticum (3.01%), Spirocerca lupi (1.51%), Cystoisospora spp. (1.01%), Hymenolepis diminuta (0.50%), Ascaris suum (0.50%), Moniezia expansa (0.50%), Toxascaris leonina (0.25%) and Nematodirus spp. (0.25%). Significant statistical differences (p<0.05) were found between methods regarding Ancylostomatidae and Trichuris spp.. Despite the environmental origin of the samples, the overall prevalence has been high as well as the diversity of the parasites found. In addition to the wolf health threat, some of them have zoonotic potential, underlying the need to think from the perspective of One Health.
- Search for top squark pair production in pp collisions at $ \sqrt{s}=13 $ TeV using single lepton eventsPublication . CMS collaboration (2232 authors); Nayak, Aruna; Bargassa, Pedrame; Beirão Da Cruz E Silva, Cristóvão; Calpas, Betty; Di Francesco, Agostino; Faccioli, Pietro; Gallinaro, Michele; Hollar, Jonathan; Leonardo, Nuno; Lloret Iglesias, Lara; Seixas, Joao; Toldaiev, Oleksii; Vadruccio, Daniele; Varela, Joao; Vischia, Pietro; David Tinoco Mendes, Andre; Silva, Pedro; Musella, PasqualeA search for top squark pair production in pp collisions at $ \sqrt{s}=13 $ TeV is performed using events with a single isolated electron or muon, jets, and a large transverse momentum imbalance. The results are based on data collected in 2016 with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb$^{−1}$. No significant excess of events is observed above the expectation from standard model processes. Exclusion limits are set in the context of supersymmetric models of pair production of top squarks that decay either to a top quark and a neutralino or to a bottom quark and a chargino. Depending on the details of the model, we exclude top squarks with masses as high as 1120 GeV. Detailed information is also provided to facilitate theoretical interpretations in other scenarios of physics beyond the standard model.
