Decrypting silicic magma/plug fragmentation at Azufral crater lake, Northern Andes : insights from fine to extremely fine ash morpho-chemistry

Pardo, Natalia ; Avellaneda, Jose D. ; Rausch, Juanita ; Jaramillo-Vogel, David ; Gutiérrez, Mariana ; Foubert, Anneleen

In: Bulletin of Volcanology, 2020, vol. 82, no. 12, p. 79

Azufral (SW Colombia) is a dangerous silicic volcano hosting a crater lake, which serves as an excellent example of an incipient plug disruption through phreatomagmatism. We studied the youngest succession of dilute pyroclastic density currents (PDCs) onlapping the north-eastern crater rim. Scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy was used to carry out an...

Whole-genome sequence of a colombian Acinetobacter baumannii strain, a coproducer of OXA-72 and OXA-255-like carbapenemases

Saavedra, Sandra Yamile ; Prada-Cardozo, Diego ; Rincón, Verónica ; Pérez-Cardona, Hermes ; Hidalgo, Andrea Melissa ; González, María Nilse ; Reguero, María T. ; Silva, Emilia M. Valenzuela de ; Mantilla, José R. ; Falquet, Laurent ; Barreto-Hernández, Emiliano ; Duarte, Carolina

In: Genome Announcements, 2017, vol. 5, no. 7, p. e01558-16

Colombian Acinetobacter baumannii strain ST920 was isolated from the sputum of a 68-year-old male patient. This isolate possessed blaOXA-72 and blaOXA-255-like genes. The assembled genome contained 4,104,098 pb and 38.79% G+C content. This is the first case reported of the coproduction (blaOXA-72 and blaOXA-255-like) of carbapenem-hydrolyzing class D β-lactamases (CHDLs) in Acinetobacter...

Draft genome sequences of multidrug-resistant acinetobacter sp. strains from colombian hospitals

Barreto-Hernández, Emiliano ; Falquet, Laurent ; Reguero, María T. ; Mantilla, José R. ; Valenzuela, Emilia M. ; González, Elsa ; Cepeda, Alexandra ; Escalante, Andrea

The draft genome sequences of the strains Acinetobacter baumannii 107m, Acinetobacter nosocomialis 28F, and Acinetobacter pittii 42F, isolated from Colombian hospitals, are reported here. These isolates are causative of nosocomial infections and are classified as multidrug resistant, as they showed resistance to four different antibiotic groups.

Genome-based characterization of two Colombian clinical Providencia rettgeri isolates co-harboring NDM-1, VIM-2, and other β-lactamases

Piza-Buitrago, Adriana ; Rincón, Verónica ; Donato, John ; Saavedra, Sandra Yamile ; Duarte, Carolina ; Morero, Jaime ; Falquet, Laurent ; Reguero, María Teresa ; Barreto-Hernández, Emiliano

In: BMC Microbiology, 2020, vol. 20, no. 1, p. 345

Providencia rettgeri is a nosocomial pathogen associated with urinary tract infections and related to Healthcare-Associated Infection (HAI). In recent years isolates producing New Delhi Metallo-β-lactamase (NDM) and other β-lactamases have been reported that reduce the efficiency of clinical antimicrobial treatments. In this study, we analyzed antibiotic resistance, the presence of...

Targeted Capture of Hundreds of Nuclear Genes Unravels Phylogenetic Relationships of the Diverse Neotropical Palm Tribe Geonomateae

Loiseau, Oriane ; Olivares, Ingrid ; Paris, Margot ; Harpe, Marylaure de La ; Weigand, Anna ; Koubínová, Darina ; Rolland, Jonathan ; Bacon, Christine D. ; Balslev, Henrik ; Borchsenius, Finn ; Cano, Angela ; Couvreur, Thomas L. P. ; Delnatte, César ; Fardin, Frédérique ; Gayot, Marc ; Mejía, Fabian ; Mota-Machado, Talita ; Perret, Mathieu ; Roncal, Julissa ; Sanin, Maria José ; Stauffer, Fred ; Lexer, Christian ; Kessler, Michael ; Salamin, Nicolas

In: Frontiers in Plant Science, 2019, vol. 10, p. -

The tribe Geonomateae is a widely distributed group of 103 species of Neotropical palms which contains six ecologically important understory or subcanopy genera. Although it has been the focus of many studies, our understanding of the evolutionary history of this group, and in particular of the taxonomically complex genus Geonoma, is far from complete due to a lack of molecular data....
