The Genetic Analysis of an Acinetobacter johnsonii Clinical Strain Evidenced the Presence of Horizontal Genetic Transfer
(Public Library of Science, 2016-08)
Acinetobacter johnsonii rarely causes human infections. While most A. johnsonii isolates are susceptible to virtually all antibiotics, strains harboring a variety of β-lactamases have recently been described. An A. johnsonii ...
Characterization of Emerging Pathogens Carrying bla KPC-2 Gene in IncP-6 Plasmids Isolated From Urban Sewage in Argentina
(Frontiers Media, 2021-08)
Untreated wastewater is a reservoir for multidrug-resistant bacteria, but its role in the spread of antibiotic resistance in the human population remains poorly investigated. In this study, we isolated a KPC-2-producing ...
First detection of a transferable bla CTX-M-14b gene in a Klebsiella pneumoniae clinical isolate from Tunisia and analysis of its genetic context
(Inst Microbiologia, 2012-03)
Klebsiella pneumoniae ML2508 was isolated from a patient at the surgery unit of the Military Hospital (Hôpital Militaire de Tunis), Tunisia. It was identified as a producer of extended-spectrum β-lactamases (ESBLs) by the ...
Complete sequence of the IncA/C 1 plasmid pCf587 carrying bla PER-2 from citrobacter freundii
(American Society for Microbiology, 2018-05)
The bla PER-2 -harboring plasmid pCf587 (191,541 bp) belongs to lineage IncA/C 1 and is closely related to pRA1. It contains a large resistance island including the bla PER-2 gene between two copies of ISKox2-like elements, ...
Lateral Antimicrobial Resistance Genetic Transfer is active in the open environment
(Nature Publishing Group, 2017-03-31)
Historically, the environment has been viewed as a passive deposit of antimicrobial resistance mechanisms, where bacteria show biological cost for maintenance of these genes. Thus, in the absence of antimicrobial pressure, ...
Genetic Diversity of KPC-Producing Escherichia coli, Klebsiella oxytoca, Serratia marcescens , and Citrobacter freundii Isolates from Argentina
(Mary Ann Liebert, 2017-12)
The predominance of Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae was caused by the spread of ST258 clone. In Latin America, KPC was reported in 2006, with the isolation of genetically unrelated K. ...
Gulls as carriers of antimicrobial resistance genes in different biogeographical areas of South America
(Academia Brasileira de Ciencias, 2021-06)
The aim of this communication was to establish if Enterobacterales associated with gulls in Argentina harbored antimicrobial resistance (AMR) genes. We analyzed cloacal swabs in two contrasting areas: Ensenada, Buenos Aires ...
Identification of the first blaCMY-2 gene in Salmonella enterica serovar Typhimurium isolates obtained from cases of paediatric diarrhoea illness detected in South America
(Elsevier, 2013-05)
The objectives of this study were to investigate clinical isolates of Salmonella enterica serovar Typhimurium resistant to β-lactam antibiotics, to characterise their mechanisms of antibiotic resistance and to evaluate the ...
Hippocampal dendritic spines remodeling and fear memory are modulated by GABAergic signaling within the basolateral amygdala complex
(Wiley-liss, Div John Wiley & Sons Inc, 2015-05)
GABAergic signaling in the basolateral amygdala complex (BLA) plays a crucial role on the modulation of the stress influence on fear memory. Moreover, accumulating evidence suggests that the dorsal hippocampus (DH) is a ...
Novel class 1 Integrons and sequence types in VIM-2 and VIM-11-producing clinical strains of Enterobacter cloacae
(Elsevier Science, 2017-07)
All VIM-producing Enterobacteriaceae (six Enterobacter cloacae) submitted to the Argentinian Reference Laboratory in Antimicrobial Resistance in the period 2008-13 were characterized. The isolates were referred from 6 ...
