Effectiveness of a Novel Liposomal Methylglyoxal-Tobramycin Formulation in Reducing Biofilm Formation and Bacterial Adhesion.

The emergence of multidrug-resistant bacteria presents a significant global health threat. Liposomal antibiotics have shown a potential to improve antibiotic delivery and efficacy. This study aimed to develop liposomes encapsulating tobramycin (TOB) and methylglyoxal (MGO) to enhance TOB activity while reducing bacterial adhesion and biofilm formation.

Putative Biosynthesis of Talarodioxadione & Talarooxime from .

Polyesters containing 2,4-dihydroxy-6-(2-hydroxypropyl)benzoate and 3-hydroxybutyrate moieties have been isolated from many fungal species. was previously reported to produce a similar polyester, talapolyester G. The complete genome sequence and the development of bioinformatics tools have enabled the discovery of the biosynthetic potential of this microorganism.

Antibacterial Efficacy of Liposomal Formulations Containing Tobramycin and -Acetylcysteine against Tobramycin-Resistant , , and .

The antibacterial activity and biofilm reduction capability of liposome formulations encapsulating tobramycin (TL), and Tobramycin--acetylcysteine (TNL) were tested against tobramycin-resistant strains of , and in the presence of several resistant genes. All antibacterial activity were assessed against tobramycin-resistant bacterial clinical isolate strains, which were fully characterized by whole-genome sequencing (WGS). All isolates acquired one or more of AMEs genes, efflux pump genes, OMP genes, and biofilm formation genes.

Enhancing azithromycin antibacterial activity by encapsulation in liposomes/liposomal-N-acetylcysteine formulations against resistant clinical strains of .

is an that could develop resistance to various antibiotics and become a multi-drug resistant (MDR) bacterium. Options for treating MDR are limited and the pipeline is somewhat dry when it comes to antibiotics for MDR bacteria, so we aimed to explore more options to help in treating MDR . The purpose of this study is to examine the synergistic effect of a liposomal formulations of co-encapsulated azithromycin and N-acetylcysteine against Liposomal azithromycin (LA) and liposomal azithromycin/N-acetylcysteine (LAN) were compared to free azithromycin.

Metabolically engineered recombinant for the production of 2-Deoxy--inosose (2-DOI).

is a versatile industrial host for chemical production and has been engineered to produce efficiently many valuable compounds. 2-Deoxy--inosose (2-DOI) is an important precursor for the biosynthesis of 2-deoxystreptamine-containing aminoglycosides antibiotics and benzenoid metabolites. Bacterial and cyanobacterial strains have been metabolically engineered to generate 2-DOI; nevertheless, the production of 2-DOI using a yeast host has not been reported.

Variations in Essential Oil Compositions of Lavandula pubescens (Lamiaceae) Aerial Parts Growing Wild in Yemen.

Lavandula pubescens Decne. is one of five Lavandula species growing wild in Yemen. The plant is used in Yemeni traditional medicine, and the essential oil tends to be rich in carvacrol.
