Occurrence of Multidrug‐Resistant Salmonella spp. in Raw Meat Retailed in Wet Markets in Chattogram City, Bangladesh

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Multidrug‐resistant Salmonella was detected in 13.5% of the raw meat samples in Chattogram, with resistance to multiple antibiotics and a high prevalence of the blaTEM gene. These findings highlight significant foodborne AMR risks and underscore the need for urgent One Health interventions to protect public health.

Effect of lipid modification and AcrA-lipid interactions on the structure and oligomerization of AcrA [PDF]

open access: yes, 2009
A wide range of antibacterial agents including antibiotics can be expelled out of the cell by AcrAB-TolC complex. In this complex, the membrane fusion protein AcrA is located in the periplasm and essential for drug efflux.

Detection of AcrA and TolC in Klebsiella pneumoniae isolates. [PDF]

open access: yes, 2013
Top part, immunodetection was carried out with antiserum directed against denatured AcrA; bottom part, immunodetection was carried out with antiserum directed against denatured TolC porin. WT, E.

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.

Periplasmic adaptor protein AcrA has a distinct role in the antibiotic resistance and virulence of Salmonella enterica serovar Typhimurium [PDF]

open access: yes, 2009
Objectives: AcrA can function as the periplasmic adaptor protein (PAP) in several RND tripartite efflux pumps, of which AcrAB-TolC is considered the most important. This system confers innate multiple antibiotic 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.

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.

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
