- Abstract:
- ... Chitosan is the second most abundant polymer obtained from the byproduct of seafood. Chitosan and its derivatives and chitosan loaded drugs are the recent area of interest against microbial pathogenesis. The cationic chitosan nanoparticles (ChNPs) interact with the anionic surfaces of the microbial cell membrane, which promotes antimicrobial activity. Although, ChNPs are potential against pathogen ...

- Abstract:
- ... As one of the most popular beverage, beer has strong resistance to bacteria except for lactic acid bacteria (LAB), as its strong viability in beer. Contaminating LAB results in beer spoilage. HorA gene carried by beer spoilage lactobacillus confers hop resistance and is associated with the growth of Lactobacillus in beer, thus can be used as a perfectly valid genetic marker for the detection of be ...

- Abstract:
- ... A novel N-acyl substituted indole-linked benzimidazoles and naphthoimidazoles were synthesized. Their chemical structures were confirmed using spectroscopic tools including 1H NMR, 13C NMR and CHN-elemental analyses. Anti inflammatory activity for all target compounds was evaluated in-vitro. The synthesized compounds hinder the biofilm formation and control the growth of the pathogen, Staphylococc ...

However, the overuse of this drug has led to the emergence of resistant strains. Therefore, the search for new alternative or complementary molecules to overcome this obstacle is needed. In this objective, Peg ...

The disease causes huge financial losses to dairy industries by reduced yield and milk quality, deaths and culling of affected cows and also by associated treatment costs. The disease occurs due to invasion of the mammary glands by pathogenic bacteria followed by their multiplication in the milk prod ...
