In vivo antimicrobial activity of engineered mesoporous silica nanoparticles targeting intracellular #mycobacteria (doxycycline-loaded nanoparticles, zebrafish model of Mycobacterium marinum #infection) @lkremer1.bsky.social #DrugDevelopment

In vivo antimicrobial activity of engineered mesoporous silica nanoparticles targeting intracellular mycobacteria - Nature Communications

Current treatment options for Mycobacterium marinum infections are extensive and challenging. In this work, authors explore the potential of functionalized mesoporous silica nanoparticles as a carrier for delivery of drugs against M. marinum.

Trehalose polyphleates participate in Mycobacterium abscessus fitness and pathogenesis - PubMed

Mycobacteria produce a large repertoire of surface-exposed lipids with major biological functions. Among these lipids, trehalose polyphleates (TPPs) are instrumental in the infection of <i>Mycobacterium abscessus</i> by the therapeutic phage BPs. However, while the biosynthesis and transport of TPPs …

Together with Abdallah and Qingtian we just published this pan-genome analysis for M. marinum. I think it is a nice catalog, but standing out for me was the variation in the cpnT gene and the fact that ESX-2 is present in the majority of the M. marinum strains, just not in the type strain M...
