Metagenomics of the Human Gut Microbiome Directed by the Flow Cytometry

INTRODUCCIÓN El tracto intestinal humano está poblado por 10^13 - 10^14 bacterias que en conjunto contienen 1,000 veces más genes que el genoma humano. Varios estudios han confirmado que las bacterias del intestino influyen en la salud del cuerpo humano. Además de las bacterias, el intestino humano contiene millones de partículas virales, en su mayoría bacteriófagos. Indirectamente, por lo tanto también influyen en la salud humana. La composición microbiana varia con el individuo. Las especies más numerosas podrían definir tres grupos de individuos: según predominen Bacteroides, Prevotella o Ruminococcus. No obstatne, las funciones más importantes pueden ser realizadas por especies minorita…
Genome sequence of SeIV-1, a novel virus from the Iflaviridae family infective to Spodoptera exigua
2011
Analysis of the transcriptome of Spodoptera exigua larvae revealed the presence of several ESTs with homology to virus of the order Picornavirales and with the highest similarity to Infectious flacherie virus (Iflaviridae) that infects Bombyx mori larvae. Iflaviridae is a recently defined family of insect-infecting viruses that consist of positive single strand RNA genomes translated into a single polyprotein of around 3000 amino acids long. Using the sequence information derived from the obtained ESTs, we have completed the genomic sequence of this virus. The novel S. exigua iflavirus (SeIV-1) has a genome of 10.3 kb and codes for a 3222 aa polyprotein. Expression analysis has revealed the…
Saimniekorganisma miRNS un zarnu mikrobioma mijiedarbība dažādos kolonoskopijas izmeklējumu paraugos
2022
Cilvēka gastrointestinālajā traktā ir daudzveidīgs mikrobioms, kam ir būtiska loma veselības uzturēšanā un fizioloģisko funkciju veikšanā organismā. Mikrobioma traucējumi ietekmē imūnsistēmas funkcijas, vielmaiņu, kā arī saistīti ar dažādām slimībām. MikroRNS (miRNS) ir nozīmīga loma gēnu ekspresijas regulēšanā. Pētījumos noskaidrots, ka saimniekorganisma miRNS tieši ietekmē zarnu mikrobiomu, tādējādi potenciāli nodrošinot daudzsološu stratēģiju, lai mērķtiecīgi modificētu mikrobiomu. Lai noskaidrotu, vai pacientu, kuriem dažādu iemeslu dēļ ir veikta kolonoskopija, zarnu biopsiju miRNS korelē ar fēču mikrobiomu veikta mazo RNS un metagenoma sekvencēšana. MiR200, miR-151, miR-30 saimes pozit…
Phosphorus limitation enhances parasite impact: feedback effects at the population level
2014
Background Nutrient deficiency affects the growth and population dynamics of consumers. Endoparasites can be seen as consumers that drain carbon (C) or energy from their host while simultaneously competing for limiting resources such as phosphorus (P). Depending on the relative demands of the host and the parasite for the limiting nutrient, intensified resource competition under nutrient limitation can either reduce the parasite’s effect on the host or further reduce the fitness of the nutrient-limited host. So far, knowledge of how nutrient limitation affects parasite performance at the host population level and how this affects the host populations is limited. Results We followed the popu…
