Complete Sequence of a blaNDM-1-Harboring Plasmid in an Acinetobacter bereziniae Clinical Strain Isolated in Argentina
(American Society For Microbiology, 2015-07)
The New Delhi metallo-β-lactamase (NDM-1) was initially identified in clinical isolates of Escherichia coli and Klebsiella pneumoniae in Sweden from a patient previously hospitalized in India (1). Since then, blaNDM-1 has ...
Full characterization of an IncR plasmid harboring qnrS1 recovered from a VIM-11-producing Pseudomonas aeruginosaCaracterización completa de un plásmido portador de qnrS1 perteneciente al grupo de incompatibilidad IncR, recuperado de un aislamiento de Pseudomonas aeruginosa productor de VIM-11
(Asociación Argentina de Microbiología, 2020-03)
Introduction: Metallo-â-lactamases (MBL) producing Pseudomonas aeruginosa isolates have been well characterised. Quionolones are commonly used in the treatment of carbapenem resistant P. aeruginosa infections; however, ...
Novel class 1 integron (InS21) carrying blaCTX-M-2 in Salmonella enterica serovar infantis
(American Society for Microbiology, 2002-12)
The genetic organization of the region coding for CTX-M-2 in Salmonella enterica serovar Infantis was determined by PCR mapping. This gene seems to have been mobilized from the Kluyvera ascorbata chromosome to a complex ...
Redefining the origin and evolution of chromosomally encoded blaCTX-M/KLU in the context of a revised taxonomy of genus Kluyvera
(American Society for Microbiology, 2021-06-17)
Changes in Kluyvera taxonomy may clarify each species contribution for recruitment and dissemination of their relevant b-lactamases. The CTX-M-2 subgroup is linked to Kluyvera ascorbata, KLUC to Kluyvera cryocrescens, and ...
Acinetobacter baumannii is able to gain and maintain a plasmid harbouring In35 found in Enterobacteriaceae isolates from Argentina
(Springer, 2012-03)
The aim of this study was to determine the presence of bla CTX-M-2 in our A. baumannii population and their putative role as an alternative mechanism of resistance to third-generation cephalosporins in this species. The ...
Activation of ERK2 in basolateral amygdala underlies the promoting influence of stress on fear memory and anxiety: Influence of midazolam pretreatment
(Elsevier Science, 2013-10)
Exposure to emotionally arousing experiences elicits a robust and persistent memory and enhances anxiety. The amygdala complex plays a key role in stress-induced emotional processing and in the fear memory formation. It ...
Stress-induced resistance to the fear memory labilization/reconsolidation process. Involvement of the basolateral amygdala complex
(Pergamon-Elsevier Science Ltd, 2016-10)
Consolidated memories can enter into a labile state after reactivation followed by a restabilization process defined as reconsolidation. This process can be interfered with Midazolam (MDZ), a positive allosteric modulator ...
Changing Epidemiology of KPC Producing Klebsiella pneumoniae in Argentina: Emergence of Hypermucoviscous ST25 and High Risk Clone ST307
(Elsevier, 2019-09)
Objectives: To assess the epidemiological features of 76 Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KPC-Kp) isolates recovered from three hospitals in Buenos Aires, Argentina, during 2015–2017. ...
First case of bacteraemia due to Acinetobacter schindleri harbouring blaNDM-1 in an immunocompromised patient
(Elsevier, 2018-01)
Clinically significant NDM-1-producing Acinetobacter schindleri has not yet been described in the literature. We report the first case of bacteraemia due to an A. schindleri strain harbouring blaNDM-1 recovered from an ...
Characterization of a multidrug resistant Citrobacter amalonaticus clinical isolate harboring blaNDM-1 and mcr-1.5 genes
(Elsevier Science, 2019-01)
A multidrug resistant isolate, identified as Citrobacter amalonaticus using MALDI-TOF MS and confirmed by genomic analysis, was recovered from a pediatric patient in a hospital from Buenos Aires, Argentina. By whole-genome ...
