Project description:The common bed bug, Cimex lectularius, is an urban pest of global health significance, severely affecting the physical and mental health of humans. In contrast to most other blood-feeding arthropods, bed bugs are not major vectors of pathogens, but the underlying mechanisms for this phenomenon are largely unexplored. Here, we present the first transcriptomics study of bed bugs in response to immune challenges. To study transcriptional variations in bed begs following ingestion of bacteria, we extracted and processed mRNA from immune-related tissues of adult male bed bugs after ingestion of sterile blood or blood laced with the Gram-positive (Gr+) bacterium Bacillus subtilis or the Gram-negative (Gr–) bacterium Escherichia coli. We analyzed mRNA from the bed bugs’ midgut (the primary tissue involved in blood ingestion) and from the rest of their bodies (RoB; body minus head and midgut tissues).

Project description:Antimicrobial resistance (AMR) is one of the major challenges that humans are facing this century. Understanding the mechanisms behind the rise of AMR is crucial to tackle this global threat. Among the triggers of phenotypic antimicrobial resistance, the contribution of transition metals has been understudied in Mycobacterium abscessus (Mabs), a fast-growing non-tuberculous mycobacterium known for its extreme AMR levels. Deeper understanding of the effects of transition metal ions will be beneficial for our knowledge in AMR and the discovery of potential therapeutic targets. Here, we investigated the impact of transition metal ions, nickel, cobalt and copper on the physiology and drug susceptibility of Mabs.
