Abstract

A pesar de su importancia, el aporte de decomisos y donaciones a las colecciones biológicas ha sido muy poco cuantificado. El objetivo de este análisis fue evaluar la relevancia de las donaciones y los decomisos de material ornitológico a la Colección Nacional de Tejidos Ultracongelados del Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”. De los 10 288 tejidos de aves depositados en la colección desde su establecimiento en 2003, más de un tercio corresponde a donaciones (22% en total, 13% de particulares y 9% institucionales) y decomisos (12%). Dichos tejidos pertenecen a 28 órdenes y representan más del 50% del total de muestras de 15 de ellos. Passeriformes, Anseriformes y Procelariiformes son los grupos más representados en las donaciones y/o decomisos, aunque hay varios otros órdenes en los que este tipo de muestras son la principal fuente de tejidos, dado que se recolectan pocos ejemplares de manera activa. De las 871 especies presentes en la colección, 156 (18%) están representadas únicamente por muestras provenientes de donaciones y/o decomisos, resaltándose así su notoria relevancia. De hecho, más de la mitad de los tejidos de donaciones y alrededor de un cuarto de los decomisados han sido incorporados en al menos 46 estudios científicos. Este análisis evidencia la importancia de las donaciones y los decomisos para las colecciones biológicas y hace hincapié en la necesidad de un trabajo conjunto con instituciones públicas y privadas y de la concientización de la sociedad sobre la significancia de donar materiales biológicos a los museos. In spite of their relevance, the contribution of donated and confiscated materials to biological collections has been poorly quantified. The objective of this analysis was to evaluate the significance of donated and confiscated ornithological materials in the National Ultrafrozen Tissue Collection of the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”. Out of the 10 288 avian tissues deposited at the collection since its establishment in 2003, over one third correspond to donations (22% in total, 13% from individuals and 9% from Institutions) and confiscated specimens (12%). These tissues belong to 28 avian orders and represent over 50% of the deposited samples in 15 of them. Passeriformes, Anseriformes, and Procelariiformes are the most represented groups in donated and confiscated material, but there are other orders for which this source of samples is also the main contribution to the collection because they are not commonly captured in the field. Of the 871 species present in the collection, 156 (18%) are represented only by samples that come from donations and confiscated material. In fact, over half of the donated tissues and more than one quarter of the samples that come from confiscated specimens have been used in at least 46 different research projects. This analysis visualizes the importance that donated and confiscated specimens have for biological collections and highlights the need for joint work with private and public organizations, as well as the awareness of the society regarding the significance of donating biological materials to museums.

17. Genomic analysis of two Acinetobacter baumanniistrains belonging to two different sequence types (ST172 and ST25)

Author

Montaña, Sabrina, Vilacoba, Elisabet, Fernandez, Jennifer S., Traglia, German M., Sucari, Adriana, Pennini, Magdalena, Iriarte, Andres, Centron, Daniela, Melano, Roberto G., and Ramírez, María Soledad

Abstract

•WGS analysis and comparison of two A. baumanniistrains belonging to emergent ST25 and sporadic ST172.•Molecular characterisation revealed differences in the content of antibiotic resistance genes and mobile genetic elements.•Differences at the genomic level can in part explain the success of ST25 in comparison with ST172.•Characterisation of a previously uncharacterised ST (ST172) and further characterisation of the widely studied ST25.

26. Outbreak of Extensively Drug-Resistant Acinetobacter baumanniiIndigo-Pigmented Strains

Abstract

ABSTRACTAcinetobacter baumanniipigmented strains are not common in clinical settings. Here, we report an outbreak caused by indigo-pigmented A. baumanniistrains isolated in an acute care hospital in Argentina from March to September 2012. Pan-PCR assays exposed a unique pattern belonging to the recently described regional CC113B/CC79Pclonal complex that confirms the relevant relationships among the indigo-pigmented A. baumanniistrains. All of them were extensively drug resistant and harbored different genetic elements associated with horizontal genetic transfer, such as the transposon Tn2006, class 2 integrons, AbaR-type islands, IS125, IS26, strA, strB, florR, and the small recombinase ISCR2associated with the sul2gene preceded by ISAba1.

27. Emergence and Spread of Plasmid-Borne tet(B)::ISCR2in Minocycline-Resistant Acinetobacter baumanniiIsolates

Author

Vilacoba, Elisabet, Almuzara, Marisa, Gulone, Lucia, Traglia, German Matías, Figueroa, Silvia A., Sly, Gabriela, Fernández, Analia, Centrón, Daniela, and Ramírez, María Soledad

Abstract

ABSTRACTResistance to minocycline has emerged in multidrug-resistant Acinetobacter baumanniiisolates from Buenos Aires hospitals. Few reports about the description and dispersion of tetgenes in this species have been published. We observed the presence of tet(B) in all minocycline-resistant isolates. This gene was found to be associated with the ISCR2mobile element, which may, in part, explain its dispersion.
