Iberian red deer: paraphyletic nature at mtDNA but nuclear markers support its genetic identity
Red deer populations in the Iberian glacial refugium were the main source for postglacial recolonization and subspecific radiation in north-western Europe. However, the phylogenetic history of Iberian red deer (Cervus ... -
Identification of lptA, lpxE, and lpxO, three genes involved in the remodeling of Brucella cell envelope
The brucellae are facultative intracellular bacteria that cause a worldwide extended zoonosis. One of the pathogenicity mechanisms of these bacteria is their ability to avoid rapid recognition by innate immunity because ... -
Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection
This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having ... -
Iflavirus increases its infectivity and physical stability in association with baculovirus
Virus transmission and the prevalence of infection depend on multiple factors, including the interaction with other viral pathogens infecting the same host. In this study, active replication of an iflavirus, Spodoptera ... -
Immunization against small ruminant lentiviruses
Multisystemic disease caused by Small Ruminant Lentiviruses (SRLV) in sheep and goats leads to production losses, to the detriment of animal health and welfare. This, together with the lack of treatments, has triggered ... -
Improving the short‑term efficiency of rock phosphate‑based fertilizers in pastures by using edaphic biostimulants
Background: The use of reactive rock phosphate (RP) in acidic soils as a phosphate (P) source for pastures and crops presents attractive economic advantages with respect to soluble phosphate. However, some studies have ... -
In vivo monitoring of Staphylococcus aureus biofilm infections and antimicrobial therapy by [18F]fluoro-deoxyglucose–MicroPET in a mouse model
A mouse model was developed for in vivo monitoring of infection and the effect of antimicrobial treatment against Staphylococcus aureus biofilms, using the [18F]fluoro-deoxyglucose–MicroPET ([18F]FDG-MicroPET) image ... -
Inactivation of the Thymidylate synthase thyA in non-typeable Haemophilus influenzae modulates antibiotic resistance and has a strong impact on its interplay with the host airways
Antibacterial treatment with cotrimoxazol (TxS), a combination of trimethoprim and sulfamethoxazole, generates resistance by, among others, acquisition of thymidine auxotrophy associated with mutations in the thymidylate ... -
Increased bioethanol production from commercial tobacco cultivars overexpressing thioredoxin f grown under field conditions
Bioethanol is mainly produced from food crops such as sugar cane and maize while it has been held partly responsible for the rise of food commodity prices. Tobacco, integrated in biorefinery facilities for the extraction ... -
Increased biofilm formation by nontypeable Haemophilus influenzae isolates from patients with invasive disease or otitis media versus strains recovered from cases of respiratory infections
Biofilm formation by nontypeable (NT) Haemophilus influenzae remains a controversial topic. Nevertheless, biofilm-like structures have been observed in the middle-ear mucosa of experimental chinchilla models of otitis media ... -
Influence of crop load on the expression patterns of starch metabolism genes in alternate-bearing citrus trees
The fruit is the main sink organ in Citrus and captures almost all available photoassimilates during its development. Consequently, carbohydrate partitioning and starch content depend on the crop load of Citrus trees. ... -
Intra- and intergenerational persistence of an insect nucleopolyhedrovirus: adverse effects of sublethal disease on host development, reproduction, and susceptibility to superinfection
Sublethal infections by Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) are common in field populations of the beet armyworm (S. exigua, Hübner) in the Almerian horticultural region of Spain. Inoculation of ... -
Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region
(Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011) Artículo / ArtikuluaNitrate leaching as a result of excessive application of N-fertilizers and water use is a major problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain. Isotopic ... -
Killing niche competitors by remote-control bacteriophage induction
A surprising example of interspecies competition is the production by certain bacteria of hydrogen peroxide at concentrations that are lethal for others. A case in point is the displacement of Staphylococcus aureus by ... -
Klebsiella pneumoniae outer membrane protein A is required to prevent the activation of airway epithelial cells
Outer membrane protein A (OmpA) is a class of proteins highly conserved among the Enterobacteriaceae family and throughout evolution. Klebsiella pneumoniae is a capsulated Gram-negative pathogen. It is an important cause ... -
Lacanobia oleracea nucleopolyhedrovirus (LaolNPV): a new European species of alphabaculovirus with a narrow host range
During an insect sampling program in alfalfa crops near Montpellier, France in 2011, Lacanobia oleracea larvae were collected that died due to nucleopolyhedrovirus infection (LaolNPV). This virus was subjected to molecular ... -
Lack of relationship between Visna/maedi infection and scrapie resistance genetic markers
(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2014) Artículo / ArtikuluaThe relationship between Visna/maedi virus (VMV) antibody status and scrapie genetic resistance of 10,611 Rasa Aragonesa sheep from 17 flocks in Aragón (Spain) was investigated. The fifteen most common PRNP gene haplotypes and ... -
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members of the family Enterobacteriaceae encode the ... -
Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability
The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ... -
Lentinula edodes β-glucan enriched diet induces pro- and anti-inflammatory macrophages in rabbit
β-glucans exhibited in cell walls of several pathogens as bacteria or fungi are sensed by pathogen recognition receptors such as scavenger receptors present in antigen presenting cells, i.e., macrophages. β-glucans obtained ...
