The Vip3Ag4 insecticidal protoxin from bacillus thuringiensis adopts a tetrameric configuration that is maintained on proteolysis
(MDPI, 2017)
Artículo / Artikulua,
The Vip3 proteins produced during vegetative growth by strains of the bacterium Bacillus thuringiensis show insecticidal activity against lepidopteran insects with a mechanism of action that may involve pore formation and ...
Effect of feeding regime on composting in bins
(Taylor & Francis, 2017)
Artículo / Artikulua,
Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ...
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
(Frontiers Media, 2017)
info:eu-repo/semantics/article,
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 ...
Apoptosis, toll-like, RIG-I-like and NOD-like receptors are pathways jointly induced by diverse respiratory bacterial and viral pathogens
(Frontiers Media, 2017)
info:eu-repo/semantics/article,
Lower respiratory tract infections are among the top five leading causes of human death. Fighting these infections is therefore a world health priority. Searching for induced alterations in host gene expression shared by ...
Lentinula edodes β-glucan enriched diet induces pro- and anti-inflammatory macrophages in rabbit
(Taylor & Francis, 2017)
info:eu-repo/semantics/article,
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 ...
Resveratrol therapeutics combines both antimicrobial and immunomodulatory properties against respiratory infection by nontypeable Haemophilus influenzae
(Springer Nature, 2017)
info:eu-repo/semantics/article,
The respiratory pathogen nontypeable Haemophilus influenzae (NTHi) is an important cause of acute
exacerbation of chronic obstructive pulmonary disease (AECOPD) that requires efficient treatments.
A previous screening ...
Genetic and isotope ratio mass spectrometric evidence for the occurrence of starch degradation and cycling in illuminated Arabidopsis leaves
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Although there is a great wealth of data supporting the occurrence of simultaneous synthesis
and breakdown of storage carbohydrate in many organisms, previous 13CO2 pulse-chase
based studies indicated that starch degradation ...
Chrysodeixis chalcites nucleopolyhedrovirus (ChchNPV): natural occurrence and efficacy as a biological insecticide on young banana plants in greenhouse and open-field conditions on the Canary Islands
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Chrysodeixis chalcites, an important pest of banana crops on the Canary Islands, is usually
controlled by chemical insecticides. The present study aimed to evaluate the efficacy of the
most prevalent isolate of the ...
Co-infection with iflaviruses influences the insecticidal properties of Spodoptera exigua multiple nucleopolyhedrovirus occlusion bodies: implications for the production and biosecurity of baculovirus insecticides
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Biological insecticides based on Spodoptera exigua multiple nucleopolyhedrovirus
(SeMNPV) can efficiently control S. exigua larvae on field and greenhouse crops in many
parts of the world. Spanish wild populations and ...
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
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 ...
