Reprogramming of gene expression in Escherichia coli cultured on pyruvate versus glucose
(Springer, 2019-07-30)
Previous studies revealed important roles of small RNAs (sRNAs) in regulation of bacterial metabolism, stress responses and virulence. However, only a minor fraction of sRNAs is well characterized with respect to the spectra ...
Clinical factors associated with a Candida albicans Germ Tube Antibody positive test in Intensive Care Unit patients
(BioMed Central, 2011-03)
Background: Poor outcomes of invasive candidiasis (IC) are associated with the difficulty in establishing the microbiological diagnosis at an early stage. New scores and laboratory tests have been developed in order to ...
Inability of Escherichia coli to Resuscitate from the Viable but Nonculturable State
(Symposium on Aquatic Microbial Ecology, 2007-09)
After induction of the viable but nonculturable (VBNC) state in Escherichia coli populations, we have analysed abiotic and biotic factors suggested to promote the resuscitation process. The response to the stressing ...
Mechanisms implied in Escherichia coli removal during wastewater treatment
(Symposium on Aquatic Microbial Ecology, 2011-08)
The wastewater treatment reduces the assimilable organic fraction and the number
of microorganisms of the effluents due to biological treatment and to the concentration
of bacteria in sludge after settling. Recycling of ...
Discovery and study of small RNAs in Escherichia coli using custom microarrays and next generation sequencing
(2016-12-15)
Los small RNAs (sRNAs) son moléculas de ARN no codificantes de corta longitud queregulan la estabilidad y traducción de ARN mensajeros (sus mRNA dianas), y que amenudo están implicados en el control de respuestas bacterianas ...
Composition and conservation of the mRNA-degrading machinery in bacteria
(BioMed Central, 2011)
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts. Genetic and biochemical data ...
Mycobacteria in rabbits: Searching for an efficient paratuberculosis infection model
(2016-12-16)
La paratuberculosis es una enfermedad intestinal granulomatosa crónica, producida por Mycobacterium avium subsp paratuberculosis (Map) perteneciente al complejo mycobacterium avium (MAC). Esta enfermedad que afecta ...
Study of Aspergillus fumigatus pathogenicity and identification of putative virulence genes
(2016-12-02)
Aspergillus fumigatus is considered to be the most prevalent airborne pathogenic fungus. lts infection begins with conidial germination in lungs where different types of aspergillosis can be developed. In profoundly ...
Prokaryotic Capability to Use Organic Substrates Across the Global Tropical and Subtropical Ocean
(Frontiers Media, 2020)
Prokaryotes play a fundamental role in decomposing organic matter in the ocean, but little is known about how microbial metabolic capabilities vary at the global ocean scale and what are the drivers causing this variation. ...
