Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Molecular Mechanisms of Colistin Resistance in Klebsiella pneumoniae in a Tertiary Care Teaching Hospital

Frontiers in Cellular and Infection Microbiology, 2021
BackgroundOver the last two decades, the prevalence of colistin resistance among the members of Enterobacteriaceae has been increasing, particularly among Klebsiella pneumoniae isolates; this limits the potential use of colistin and leads to worsened ...

Type IV‐Dominated Plasmid‐Encoded CRISPR‐Cas Systems Are Enriched in Multireplicon and Multi‐Stressor Resistance Plasmids Across the Global Plasmidome

Molecular Microbiology, EarlyView.
Screening 72,555 plasmid sequences reveals that intact CRISPR‐Cas systems are rare (1.03%) but strongly enriched in multireplicon and multi‐stressor resistance plasmids, with Type IV‐A as the dominant subtype. These findings implicate plasmid‐encoded CRISPR‐Cas as non‐randomly retained elements of structurally complex and high‐risk backbones.

Nonclonal Emergence of Colistin Resistance Associated with Mutations in the BasRS Two-Component System in Escherichia coli Bloodstream Isolates

mSphere, 2020
Infections by multidrug-resistant Gram-negative bacteria are increasingly common, prompting the renewed interest in the use of colistin. Colistin specifically targets Gram-negative bacteria by interacting with the anionic lipid A moieties of ...

Bacterial Agents and Their Multidrug‐Resistance Profile Among Patients Suspected of Bacterial Infections in Hakim Gizaw Hospital, Debre Berhan, Ethiopia: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 11, November 2026.
ABSTRACT Background and Aims Antimicrobial resistance is a global threat. Bacteria showed higher resistance in Ethiopia, and up‐to‐date data on it is urgently required for effective interventions. This study aimed to determine occurrence of multi‐drug‐resistant (MDR) bacterial isolates among patients presented to Hakim Gizaw Hospital (HGH).

Association of Carbapenem and Colistin Resistance in Pathogenic Gram Negative Bacteria

, 2019
Diseases caused by multidrug-resistant (MDR) bacteria continue to challenge physicians and endanger their patients’ lives. Polymyxins, including colistin, are the last resort antibiotics to treat serious infections caused by carbapenem-resistant ...

Large-scale screening of genomic data identifies novel mobile colistin resistance genes and reveals high over-representation in Pseudomonadota [PDF]

, 2023
The emergence of antibiotic-resistant bacteria is a health problem of great concern. Antibiotic resistance development is driven by selection pressure and the environment is believed to be the origin of most antibiotic resistance genes, from where they ...

Development of novel antibodies for detection of mobile colistin-resistant bacteria contaminated in meats

Scientific Reports, 2018
AbstractThe recent discovery and rapid spread of mobile colistin-resistant gene, mcr-1, among bacteria isolated from a broad range of sources is undermining our ability to treat bacterial infections and threatening human health and safety. To prevent further transfer of colistin resistance, practical and reliable methods for mcr-1-containing bacteria ...

In Vitro Study of IS Apl1 -Mediated Mobilization of the Colistin Resistance Gene mcr-1 [PDF]

Antimicrobial Agents and Chemotherapy, 2017
ABSTRACT The plasmid-mediated mcr-1 gene encodes a phosphoethanolamine transferase that confers resistance to polymyxins. The mcr-1 gene is associated with insertion sequence IS Apl1 (IS 30 family).

Biofilm‐Mediated Persistence of Salmonella in Poultry Processing: A Comprehensive Review of Isolate Heterogeneity, Stress Adaptation, and Antimicrobial Resistance

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Salmonella enterica remains a major foodborne pathogen in poultry‐processing environments, where its persistence is largely attributed to biofilm formation on food‐contact and non‐food‐contact surfaces. Despite extensive research on Salmonella control, persistent contamination continues to challenge food safety due to the complex interplay ...
