Epidemiological and genetic characteristics of clinical carbapenemase-producing Enterobacterales isolates from Batna hospitals in Algeria.

Background: Carbapenemase-producing Enterobacterales isolates are associated with significant mortality and have emerged as a major problem in healthcare settings worldwide.

Objective: Our aim was to investigate the epidemiological and genotypic characteristics of carbapenemase-positive Enterobacterales isolates from patients hospitalised in three hospitals in the city of Batna, Algeria.

Methods: Between 2016 and 2019, a total of 5,316 clinical isolates were obtained.

Clonal dissemination of an NDM-2-producing Acinetobacter baumannii ST103 clone resulting in an outbreak in an intensive care unit of a Lebanese tertiary care hospital.

Objective: Multidrug-resistant bacteria, including carbapenem-resistant Acinetobacter baumannii (CRAB), are considered a major public health threat, particularly those which are responsible for nosocomial infections. This study aimed to investigate the molecular mechanism of carbapenem resistance and the clonal relationship of CRAB isolates of a probable outbreak in the intensive care unit (ICU) of Saydet Zgharta University Medical Center, in north Lebanon.

Methods: Thirty-two non-duplicate CRAB isolates were collected from patients hospitalised in the ICU.

The effect of combinations of a glyphosate-based herbicide with various clinically used antibiotics on phenotypic traits of Gram-negative species from the ESKAPEE group.

The emission of glyphosate and antibiotic residues from human activities threatens the diversity and functioning of the microbial community. This study examines the impact of a glyphosate-based herbicide (GBH) and common antibiotics on Gram-negative bacteria within the ESKAPEE group (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp. and Escherichia coli).

Mechanisms of acquisition of the vanA operon among vancomycin-resistant Staphylococcus aureus genomes: The tip of the iceberg?

Background: Vancomycin is frequently used as a last line of defence against infections due to multidrug-resistant Staphylococcus aureus (S. aureus). A recent finding described the acquisition of vancomycin-resistant S.

Algerian postcaesarean surgical site infections: A cross-sectional investigation of the epidemiology, bacteriology, and antibiotic resistance profile.

Background: Surgical site infections (SSIs) are one of the most common health care-associated infections in low and middle-income countries. The aims of this cross-sectional descriptive study were to estimate the frequency of postcaesarean infection with associated clinical characteristics and the antibiotic resistance profile of bacterial isolates.

Methods: Patients who underwent a cesarean section at the obstetrics and gynecology department of the hospital in Annaba, Algeria were included.

Co-existence of NDM-, aminoglycoside- and fluoroquinolone-resistant genes in carbapenem-resistant clinical isolates from Pakistan.

To determine the prevalence of antimicrobial-resistant genes in carbapenem-resistant (CRECO). A total of 290 carbapenem-resistant bacteria were collected from tertiary care hospitals in Lahore (Pakistan). These isolates were confirmed by VITEK 2 and matrix-assisted laser desorption/ionization time of flight.

The Emergence of Carbapenem- and Colistin-Resistant Enterobacteria in Senegal.

Antibiotic resistance is a public health problem. The emergence of carbapenemase-producing Enterobacterales (CPE) infections is a concern, particularly in Senegal. (1) Methods: Between January 2019 and July 2022, 240 isolates of enterobacteria resistant to third-generation cephalosporins and imipenem from biological samples from Fann Hospital (Dakar) and Hôpital Paix (Ziguinchor) were selected.

Heteroresistance to Colistin in Clinical Isolates of Producing OXA-48.

Heteroresistance to colistin can be defined as the presence of resistant subpopulations in an isolate that is susceptible to this antibiotic. Colistin resistance in Gram-negative bacteria is more frequently related to chromosomal mutations and insertions. This work aimed to study heteroresistance in nine clinical isolates of producing OXA-48 and to describe genomic changes in mutants with acquired resistance in vitro.

Origin, Diversity, and Multiple Roles of Enzymes with Metallo-β-Lactamase Fold from Different Organisms.

β-lactamase enzymes have generated significant interest due to their ability to confer resistance to the most commonly used family of antibiotics in human medicine. Among these enzymes, the class B β-lactamases are members of a superfamily of metallo-β-lactamase (MβL) fold proteins which are characterised by conserved motifs (i.e.

Using Genomics to Decipher the Enigmatic Properties and Survival Adaptation of Candidate Phyla Radiation.

Microbial ecology is a critical field for understanding the composition, diversity, and functions of microorganisms in various environmental and health-related processes. The discovery of Candidate Phyla Radiation (CPR) through culture-independent methods has introduced a new division of microbes characterized by a symbiotic/parasitic lifestyle, small cell size, and small genome. Despite being poorly understood, CPRs have garnered significant attention in recent years due to their widespread detection in a variety of environmental and clinical samples.

The risk of pig and chicken farming for carriage and transmission of containing extended-spectrum beta-lactamase (ESBL) and mobile colistin resistance () genes in Thailand.

South-East Asian countries report a high prevalence of extended-spectrum cephalosporin- (ESC-) and colistin-resistant (Col-R-). However, there are still few studies describing the molecular mechanisms and transmission dynamics of ESC-R- and, especially, Col-R-. This study aimed to evaluate the prevalence and transmission dynamics of containing extended spectrum beta-lactamases (ESBL) and mobile colistin resistance () genes using a 'One Health' design in Thailand.
