Genomic Variation and Population Structure of Portuguese Native Dog Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

AcrAB-TolC Efflux Pump Mediated Resistance to Carbapenems among Clinical Isolates of Enterobacteriaceae

open access: yesJournal of Pure and Applied Microbiology, 2022
AcrAB-TolC is a resistance nodulation division type of efflux pump present in Enterobacteriaceae. It non-specifically effluxes antibiotics out of the bacterial cell, thus conferring drug resistance.

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.

NUTRIENT ACCUMULATION IN THE ABOVEGROUND BIOMASS, IN THE LITTER LAYER AND PHYLLODIES DECOMPOSITION OF Acacia mangium Willd.

open access: yesCiência Florestal, 2010
Nutrient concentrations and contents in the shoot (leaves, branches, bark and wood) in a five-years-old stand of Acacia mangium Willd. (mangium), decomposition rate of mangium phyllodies (modified leaves) and nutrient efficiency use were evaluated in a ...

Evaluation of Catechin Synergistic and Antibacterial Efficacy on Biofilm Formation and acrA Gene Expression of Uropathogenic E. coli Clinical Isolates

open access: yesAntibiotics, 2022
Uropathogenic Escherichia coli has a propensity to build biofilms to resist host defense and antimicrobials. Recurrent urinary tract infection (UTI) caused by multidrug-resistant, biofilm-forming E.

Kontrollierter Transport und lichtinduzierte Freisetzung von Magic Spot Nukleotiden in Escherichia coli

open access: yesAngewandte Chemie, Volume 138, Issue 15, 6 April 2026.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Plasmid-instability in acrA Mutants of Escherichia coli K12 [PDF]

open access: yesJournal of General Microbiology, 1974
SUMMARY: The effect of a mutation at acrA, which alters the bacterial membrane, on plasmid stability was studied. F-gal + residing in the mutant was remarkably unstable in the presence of acridine dyes or at high temperature (42°C) as compared with wild-type (acrA +) strains.

Study of Plasmid-Mediated Quinolone Resistance in Klebsiella pneumoniae: Relation to Extended-Spectrum Beta-Lactamases

open access: yesJournal of Pure and Applied Microbiology, 2022
Klebsiella pneumoniae (K. pneumoniae) is an important pathogen associated with various infections. The emergence of antibiotic resistances, such as quinolone resistance and those due to extended-spectrum beta-lactamases (ESBL), reduces the available ...

Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 15, 6 April 2026.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a
