Photodynamic therapy for ESKAPE pathogens: An emerging approach to combat antimicrobial resistance (AMR).
Microb Pathog

The increase in antimicrobial resistance, particularly in ESKAPE pathogens, has resulted in the dire need for new therapeutic approaches. ESKAPE is an acronym for a group of bacteria that are responsible for a majority of nosocomial and community acquired infections. The acronym stands for Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species.

Article Synopsis
- Eukaryotic genes contain introns that need to be spliced out of mRNA, with the organism in question having over 90,000 of the shortest introns reported.
- The study investigated how nucleosome positioning affects intron recognition and found that introns are often near nucleosome edges, suggesting an evolutionary trend favoring this location.
- While higher splicing efficiency was noted for edge-located introns, the analysis revealed that low GC content of the introns is a more significant factor for splicing efficiency than their positioning relative to nucleosomes.

Chloroviruses (family ) infect eukaryotic, freshwater, unicellular green algae. A unique feature of these viruses is an abundance of DNA methyltransferases, with isolates dedicating up to 4.5% of their protein coding potential to these genes.

The pervasiveness of sex despite its well-known costs is a long-standing puzzle in evolutionary biology. Current explanations for the success of sex in nature largely rely on the adaptive significance of the new or rare genotypes that sex may generate. Less explored is the possibility that sex-underlying molecular mechanisms can enhance fitness and convey benefits to the individuals that bear the immediate costs of sex.

Among ciliates, Paramecium has become a privileged model for the study of "species problem" particularly in the case of the "Paramecium aurelia complex" that has been intensely investigated. Despite extensive studies, the taxonomy of Paramecium is still challenging. The major problem is an uneven sampling of Paramecium with relatively few representatives of each species.
