GeoHealth, Volume 10, Issue 2, February 2026.Abstract Antibiotic resistance is a significant threat to global public health and can disproportionately affect low‐ and middle‐ income countries (LMICs). There is a lack of studies focusing on antibiotic resistance in coral reef regions and environmental reservoirs in Central America.

Phenotypic and Genotypic Profile of Enterobacteriaceae Isolated at a Teaching Hospital in Ghana
MicrobiologyOpen, Volume 14, Issue 6, December 2025.This study identified a significant prevalence of antimicrobial resistance determinants within Enterobacteriaceae isolates, with particular emphasis on those producing extended‐spectrum β‐lactamases (ESBL). These isolates harbored diverse antibiotic resistance genes (ARGs), plasmid replicons, and virulence factors (VFs), highlighting the imperative for

Plasmid-mediated Colistin Resistance mcr-1 in A Clinical Isolate of Escherichia coli ST19 in Algeria
Journal of Microbiology and Infectious Diseases, 2020 We describe the emergence of plasmid-mediated colistin resistance mcr-1 in a clinical isolate of Escherichia coli ST19. The strain was isolated from a urine sample of a 75-year-old male patient.

Characterization of the extracellular lipase of Bacillus subtilis and its relationship to a membrane-bound lipase found in a mutant strain [PDF]
, 1979 Bacillus subtilis CMK33 is a mutant that is more osmotically fragile than the wild type when it is converted to the protoplast form. The protoplasts of this mutant contain a membrane-bound lipase, which is not found in protoplasts of the wild type ...

MicrobiologyOpen, Volume 14, Issue 6, December 2025.In a protected forest fragment in southern Brazil, 197 wild birds were sampled, with 12.2% carrying Staphylococcus aureus. Two MRSA ST398 strains, the first reported in Brazilian wild birds, were identified. Genomic analysis revealed resistance and virulence genes, linking these strains to pigs and underscoring the critical need for resistance ...

Artificial Conjugation in Escherichia coli and Transfer of Penicillinase Plasmid
پزشکی بالینی ابن سینا, 1999 Conjugation is a major mechanism of DNA transfer among bacteria which takes place in both laboratory and natural environment and brings about new characteristics. Extrachromosomal DNA called plasmid are important elements in this exchange.
