Microbiota gastrointestinal y síndrome de intestino irritable by García Mazcorro, José Francisco, Cruz Valdez, Julio César, Marroquín Cardona, Alicia Guadalupe, Sánchez Casas, Rosa María

“…The differences in sequencing of these hypervariable regions make it possible to taxonomically identify the bacteria present in study samples (for example, in stools and intestinal mucosa).3 The «rrs» gene, also known as 16S ribosomal DNA or 16S rDNA, as mentioned in table 3 of our article, encodes 16S rRNA. …”

EL POLIEDRO RETÓRICO by Montes, Felipe

“…En esta labor es clara una influencia inductiva que va de los contenidos y de los usos acostumbrados hacia la tipología y la taxonomía de las figuras. Por ejemplo, aunque los procesos cognitivos que generan una descripción pueden diferenciarse y tipificarse, la mayoría de los diccionarios y tratados de retórica y poética distinguen entre retrato, descripción de la apariencia de una persona, y topografía, descripción de un lugar real. …”

Universal primers for the amplification and sequence analysis pf actin-1 from diverse mosquito species by Staley, Molly, Dorman, Karin S., Bartholomay, Lyric C., Fernández Salas, Ildefonso, Farfán Ale, José Arturo, Loroño Pino, María Alba, García Rejón, Julián Everardo, Ibarra Juárez, Luis Arturo, Blitvich, Bradley J.

“…We report the development of universal primers for the reverse-transcription polymerase chain reaction (RT-PCR) amplification and nucleotide sequence analysis of actin cDNAs from taxonomically diverse mosquito species. Primers specific to conserved regions of the invertebrate actin-1 gene were designed after actin cDNA sequences of Anopheles gambiae, Bombyx mori, Drosophila melanogaster, and Caenorhabditis elegans. …”

A new parrot taxon from the Yucatán Peninsula, Mexico—its position within genus Amazona based on morphology and molecular phylogeny by Silva, Tony, Guzmán, Antonio, Urantówka, Adam D., Mackiewicz, Paweł

“…However, taken together tree topology tests and morphometric analyses, we can conclude that the new parrot represents a recently evolving species, whose taxonomic status should be further confirmed. This lineage diverged from its closest relative about 120,000 years ago and was subjected to accelerated morphological and behavioral changes like some other representatives of the genus Amazona. …”

Synopsis of the pelidnotine scarabs (Coleoptera, Scarabaeidae, Rutelinae, Rutelini) and annotated catalog of the species and subspecies by Moore, Matthew R., Jameson, Mary L., Garner, Beulah H., Audibert, Cédric, Smith, Andrew B. T., Seidel, Matthias

“…These beetles suffer from a complicated nomenclatural history, due primarily to 20th century taxonomic and nomenclatural errors. We review the taxonomic history of the pelidnotine scarabs, present a provisional key to genera with overviews of all genera, and synthesize a catalog of all taxa with synonyms, distributional data, type specimen information, and 107 images of exemplar species. …”

Discovery of a Novel Polyomavirus in Acute Diarrheal Samples from Children by Ramqvist, Torbjörn, Yu, Guixia, Greninger, Alexander L., Isa, Pavel, Phan, Tung G., Martínez, Miguel Angel, De la Luz Sanchez, Maria, Contreras, Juan Francisco, Santos Preciado, José Ignacio, Parsonnet, Julie, Miller, Steve, DeRisi, Joseph L., Delwart, Eric, Arias Ortiz, Carlos Federico, Chiu, Charles Y.

“…The ,5.0 kB viral genome exhibits little overall homology (,46% amino acid identity) to known polyomaviruses, and, due to phylogenetic variation among its individual proteins, cannot be placed in any existing taxonomic group. PCR-based screening detected MXPyV in 28 of 834 (3.4%) fecal samples collected from California, Mexico, and Chile, and 1 of 136 (0.74%) of respiratory samples from Mexico, but not in blood or urine samples from immunocompromised patients. …”

W., Folch Mallol, Jorge Luis

“…Following screening of fourteen fungi isolated from the deep-sea sponge Stelletta normani sampled at a depth of 751 metres, three halotolerant strains (TS2, TS11 and TS12) were identified which displayed high CMCase and xylanase activities. Molecular based taxonomic approaches identified these strains as Cadophora sp. …”
