Polar flagellin glycan heterogeneity of Aeromonas hydrophila strain ATCC 7966T
Motile pathogens often rely upon flagellar motility as an essential virulence factor and in many species the structural flagellin protein is glycosylated. Flagellin glycosylation has been shown to be important for proper ...
Comparison of officacy and safety of preventive measures used against canine leishmaniasis in southern European countries:longitudinal retrospective study in 1647 client-owned dogs (2012-2016)
The best preventive strategy for canine leishmaniosis is unknown. In the last few years, new preventive measures have become available in Europe, including vaccination against leishmaniosis and use of domperidone. The ...
Rare Variant Association Analysis Uncovers Involvement of VNN2 in Stroke Outcome
<h3><strong>BACKGROUND:</strong></h3><p>A stroke’s functional outcome presents vast variability among patients, which is influenced by age, sex, characteristics of the lesion, and genetic factors. However, there is little ...
Who arrived first? Priority effects on Candida albicans and Pseudomonas aeruginosa dual biofilms
Historical processes in community assembly, such as species arrival order, influence interactions, causing priority effects. Candida albicans and Pseudomonas aeruginosa often co-occur in biofilm-based infections of the ...
Microbial and physicochemical parameters associated with Legionella contamination in hot water recirculation systems
Hot water recirculation systems (HWRS) in hotels and nursing homes, which are common in countries such as Spain, have been related to outbreaks of legionellosis. To establish the relationships of microbial and physicochemical ...
Comparative Study of Iron and Trace Element Mobilization during Fe-Oxide Bioreduction in Mine Tailings: a case study of Ensenada Chapaco (Chile) and Portman Bay (Spain)
Bioreduction of Feoxides in mine tailings deposited under marine conditions releases Fe and associated trace elements (e.g. Ti, Ni, Cd, Pb), leading to contamination of the marine environment. Sea-Tailings Disposal (STD) ...
Myriapod Metallothioneins conserve the ancestral architecture of Arthropods while displaying lineage-specific adaptations in metal binding
Metallothioneins (MTs) are central to metal metabolism and contribute to organismal adaptation to variable metal bioavailability across ecosystems. Although well studied in chordates and mollusks, MTs remain poorly ...
Minimizing Errors in RT-PCR Detection and Quantification of SARS-CoV-2 RNA for Wastewater Surveillance
Aquest article és una revisió tècnica que aborda la necessitat crítica d'estandarditzar els protocols de vigilància del <strong>SARS-CoV-2</strong> en aigües residuals per evitar errors de falsos positius i negatius. Tot ...
Infective endocarditis after transcatheter versus surgical aortic valve replacement
Abstract Background Scarce data are available comparing infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). This study aimed to compare the ...
A contemporary picture of coagulase-negative staphylococcal endocarditis: a Nationwide GAMES Cohort Study
Background Coagulase-negative staphylococci (CoNS) are an increasingly common cause of infective endocarditis (IE) and lack recent data from large studies. Objectives Our aim was to describe the epidemiology, clinical ...
Surveillance of SARS-CoV-2, rotavirus, norovirus genogroup II and human adenovirus in wastewater as an epidemiological tool to anticipate outbreaks of COVID-19 and acute gastroenteritis in a city without a wastewater treatment plant in the Peruvian Highlands
Aquest estudi realitzat a una ciutat dels Andes peruans, sense planta de tractament d'aigües residuals, reafirma l'eficàcia de l'<strong>epidemiologia basada en les aigües residuals (WBE)</strong> com a eina d'alerta ...
Description of a novel viral tool to identify and quantify ovine faecal pollution in the environment
Aquest estudi identifica i valida el <strong>poliomavirus oví (OPyV)</strong> com un nou marcador genètic per al seguiment de l'origen de la contaminació fecal (<strong>Microbial Source Tracking</strong>), omplint un buit ...
Long-read sequencing reveals increased isoform diversity in key transcription factor effectors of intercellular signalling at the invertebrate-vertebrate transition
<p><strong>Background</strong></p><p>Several intercellular signalling pathways (including wingless (Wnt), hedgehog (Hh), and bone morphogenetic protein (BMP)) are used repeatedly in animals throughout development and ...
Detection and quantification of classic and emerging viruses by skimmed-milk flocculation and PCR in river water from two geographical areas
Aquest estudi valida un mètode de concentració <strong>econòmic i senzill</strong> (basat en la floculació amb llet descremada) per analitzar la presència de virus en mostres de 10 litres d'aigua de riu a Barcelona i Rio ...
Effect of temperature and sunlight on the stability of human adenoviruses and MS2 as fecal contaminants on fresh produce surfaces
Aquest estudi avalua com la temperatura i la llum solar influeixen en la persistència de l'<strong>adenovirus humà (HAdV)</strong> i el bacteriòfag MS2 en superfícies d'enciams i maduixes, productes frescos clau en la ...
Sobre el respecte pels animals
Per sobreviure, les persones hem d’alimentar-nos. Menjar no és només un acte biològic, sinó també un fet cultural, social i, fins i tot, moral. La manera com mengem diu més de nosaltres del que sovint admetem. A través de ...
