First record of glycera guatemalensis and G. sphyrabrancha (Annelida: Glyceridae) from Western México by De León González, Jesús Ángel, Tovar Hernández, María Ana, Torres Manríquez, Iliana, García Garza, María Elena

“…Methods: An analysis of the glycerides of the Pacific coast of Mexico was carried out, finding two species that were collected, one of shrimp trawl at a depth of 18 meters off Puertecitos, Baja California, as well as by manual sampling in the intertidal zone of Concepción Bay, Baja California Sur in the Gulf of California. For their taxonomic determination, morphological characters of greater relevance for their identification were examined, such as jaws, aileron shape, parapodia, chaetae, and the type of pharyngeal papillae. …”

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. …”

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. …”

Análisis de las poblaciones bacterianas mediante secuenciación del gen arnr 16s en un ambiente agrícola para la producción de melón (Cucumis melo l.) by Mercado Guajardo, Víctor Eduardo

“…En el análisis de resultados se encontró que las poblaciones bacterianas son similares en ambas huertas, sin embargo, al comparar las muestras se encontró que el suelo presenta una mayor biodiversidad en comparación a lo encontrado en el melón y las manos de los pizcadores, estas dos últimas, presentan una diversidad taxonómica similar. Los filos dominantes en el ambiente donde se cultiva el melón son Proteobacteria (80-90% de abundancia relativa), Firmicutes (1-10%), y Actinobacteria (<1% en melón y manos; 10-20% en suelos). …”
