Objectives: The aim of this study is to screen for, isolate and characterize a bacteriophage designated ɸEcM-vB1 with confirmed lytic activity against multidrug-resistant (MDR) E. coli. Methods done in this research are bacteriophage isolation, purification, titer determination, bacteriophage morphology, host range determination, bacteriophage latent period and burst size determination, genomic analysis by restriction enzymes, and bacteriophage total protein content determination.

Endometritis is one of the main reproductive disorders in mares and due to the increasing prevalence of antibiotic resistance, the use of probiotics in the prevention and treatment of endometritis in mares has gained interest, given their potential to restore and maintain a healthy uterine microbiota. Therefore, the aim of this study was to evaluate the antimicrobial properties of total metabolites of Lactobacillus acidophilus (LA) and Lactiplantibacillus plantarum (LP) against common equine endometrial pathogenic bacteria in vitro (Acinetobacter baumannii, Escherichia coli (1), Escherichia coli (2), Escherichia coli (3), Escherichia coli (4), Enterobacter cloacae, Streptococcus equi, Staphylococcus warneri, Actinobacillus equi and Klebesiella pneumoniae), as well as to assess their low molecular weight metabolites (loM) and extracellular vesicle (EVs) inhibition capacity over a multidrug-resistant E. coli isolated from mares with clinical endometritis.

Article Synopsis
- The rise of multidrug-resistant bacteria highlights the urgent need for new antimicrobial medicines, leading to the investigation of antimicrobial peptoids as potential alternatives.
- Thirteen peptoid analogues were synthesized with varying alkyl side chains to analyze their antibacterial properties, and only one, called Tosyl-Octyl-Peptoid (TOP), showed significant broad-spectrum bactericidal activity.
- TOP effectively kills bacteria in both dividing and non-dividing states, demonstrating promising minimum inhibitory concentrations and a high selectivity ratio, suggesting its potential as a future therapeutic option against resistant infections.

Carbapenemase producing (CPEs) represent a group of multidrug resistant pathogens for which few, if any, therapeutics options remain available. CPEs generally harbor plasmids that encode resistance to last resort carbapenems and many other antibiotics. We previously performed a high throughput screen to identify compounds that can disrupt the maintenance and replication of resistance conferring plasmids through use of a synthetic screening plasmid introduced into K-12 cells.

Background: Currently, antimicrobial agents are widely used in both animals and agriculture, causing the crisis of multidrug-resistant (MDR) bacteria. In this study we surveyed for 4 important antimicrobial-resistant bacteria: extended-spectrum β-lactamase (ESBL)-producing Escherichia coli, Klebsiella pneumoniae and Salmonella spp., and methicillin-resistant Staphylococcus aureus (MRSA) from the environment around chicken and pig farms.
