Small ruminant macrophage polarization may play a pivotal role on lentiviral infection
(BioMed Central, 2013)
info:eu-repo/semantics/article,
Small ruminant lentiviruses (SRLV) infect the monocyte/macrophage lineage inducing a long-lasting infection affecting body condition, production and welfare of sheep and goats all over the world. Macrophages play a pivotal ...
Base pairing interaction between 5′- and 3′-UTRs controls icaR mRNA translation in Staphylococcus aureus
(Public Library of Science, 2013)
Artículo / Artikulua,
The presence of regulatory sequences in the 39 untranslated region (39-UTR) of eukaryotic mRNAs controlling RNA stability
and translation efficiency is widely recognized. In contrast, the relevance of 39-UTRs in bacterial ...
Deletion of the GI-2 integrase and the wbkA flanking transposase improves the stability of Brucella melitensis Rev 1 vaccine
(BioMed Central, 2013)
Artículo / Artikulua,
Brucella melitensis Rev 1 is the best vaccine available for the prophylaxis of small ruminant brucellosis and, indirectly, for reducing human brucellosis. However, Rev 1 shows anomalously high rates of spontaneous dissociation ...
Coordinated cyclic-di-GMP repression of salmonella motility through YcgR and cellulose
(American Society for Microbiology, 2013)
Artículo / Artikulua,
Cyclic di-GMP (c-di-GMP) is a secondary messenger that controls a variety of cellular processes, including the switch between a biofilm and a planktonic bacterial lifestyle. This nucleotide binds to cellular effectors in ...
Role of bacterial surface structures on the interaction of Klebsiella pneumoniae with phagocytes
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
Phagocytosis is a key process of the immune system. The human pathogen Klebsiella pneumoniae is a well known example
of a pathogen highly resistant to phagocytosis. A wealth of evidence demonstrates that the capsule ...
Expression of a peroral infection factor determines pathogenicity and population structure in an insect virus
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A Nicaraguan isolate of Spodoptera frugiperda multiple nucleopolyhedrovirus is being studied as a possible biological
insecticide. This virus exists as a mixture of complete and deletion genotypes; the latter depend on ...
The sf32 unique gene of spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus
(SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome ...
Deletion genotypes reduce occlusion body potency but increase occlusion body production in a Colombian Spodoptera frugiperda nucleopolyhedrovirus population
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A Colombian field isolate (SfCOL-wt) of Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a mixture
of different genotypes. To evaluate the insecticidal properties of the different genotypic variants, 83 ...
Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization)
(Elsevier, 2013)
info:eu-repo/semantics/article,
The main goal of this study was to test the effect of [CO2] on C and N management in 2different plant organs (shoots, roots and nodules) and its implication in the 3responsiveness of exclusively ...
A super-family of transcriptional activators regulates bacteriophage packaging and lysis in Gram-positive bacteria
(Oxford University Press, 2013)
info:eu-repo/semantics/article,
The propagation of bacteriophages and other mobile genetic elements requires exploitation of the phage mechanisms involved in virion assembly and DNA packaging. Here, we identified and characterized four different families ...
