Six beta-lactamase-producing (Bla+) isolates of Enterococcus faecalis recovered over a 17-month period from an Argentinian pediatric hospital were found to have identical or almost identical chromosomal restriction patterns by pulsed-field gel electrophoresis, although the plasmid patterns were different. These isolates, like Bla+ enterococci in the United States, hybridized to a staphylococcal...

Klebsiella pneumoniae carbapenemase (KPC)-producing organisms are therapeutically and diagnostically challenging. It is possible that bla(KPC) gene expression plays a role in the variability observed in clinical susceptibility testing. bla(KPC) transformants together with 10 clinical isolates representing four genera were evaluated for bla(KPC) copy number and gene expression and correlated wit...

Salmonella enterica bla(CTX-M-2) and bla(CTX-M-9) plasmid backbones from isolates from Belgium and France were analyzed. The bla(CTX-M-2-)plasmids from both human and poultry isolates were related to the IncHI2 pAPEC-O1-R plasmid, previously identified in the United States in avian Escherichia coli strains; the bla(CTX-M-9) plasmids were closely related to the IncHI2 R478 plasmid.

The Amazon region comprises the largest tropical forest on planet and is responsible for absorbing huge amounts of CO2 from atmosphere. However, changes in land use cover have contributed to an increase greenhouse gas emissions, especially CO2, endangered indigenous lands protected areas region. objective this study was detect emissions removals associated with Brazilian Legal (BLA) through ana...

Introduction: Pseudomonas aeruginosa is one of the leading causes of nosocomial infections, and antibiotic resistance of this pathogen is an important concern in treating such infections. The current work was conducted to investigate the prevalence of bla-IMP, and bla-VIM metallo-beta-lactamase (MBL) among clinical and environmental P. aeruginosa isolates obtained from ICUs of different hospita...

Diabetic foot ulcer (DFU) is a common and devastating complication in diabetes. Antimicrobial resistance mediated by extended-spectrum β-lactamases (ESBLs) production by bacteria is considered to be a major threat for foot amputation. The present study deals with the detection of Escherichia coli and the prevalence of bla(TEM), bla(SHV) and bla(OXA) genes directly from biopsy and swab of foot u...

The brain comprises an excitatory/inhibitory neuronal network that maintains a finely tuned balance of activity critical for normal functioning. Excitatory activity in the basolateral amygdala (BLA), a brain region that plays a central role in emotion and motivational processing, is tightly regulated by a relatively small population of γ-aminobutyric acid (GABA) inhibitory neurons. Disruption i...
