Mycobacterium abscessus (Mab), a non-tuberculous environmental mycobacterium is one of the emerging pathogens. The number of Mab infections has doubled in the past decade. It is also an opportunistic pathogen usually infecting immunocompromised individuals and causing numerous skin and soft tissue infections. It commonly causes lung infections in people who are already infected with one or other lung infections such as tuberculosis. The treatment of Mab infections is difficult because of its intrinsic resistance to most of the antibiotics available. This project studies Rifampicin (RIF) resistance in Mab, as RIF is a well-established treatment for other mycobacterial infections including tuberculosis, …

Bacterial infections and the rise of antibiotic resistance, especially multidrug resistant strains, have generated a clear need for discovery of novel therapeutics. Most antibiotics in use today are derivatives of previous antibiotics to which resistance mechanisms already exist, and traditionally they have a single target: either a protein or rRNA. Gram-positive bacteria regulate the expression of several essential genes or operons using a mechanism called the T-box. The T-box is a structurally conserved riboswitch-like gene regulator in the 5’-untranslated region (UTR) of numerous essential genes of Gram-positive bacteria. T-boxes are stabilized by cognate, unacylated tRNA ligands, allowing the formation of …

The characterization of host-virus relationships is essential for understanding the process of viral replication and driving the development of effective viral targeting strategies. In this work, I tested the hypothesis that ribonucleic acid (RNA) post-transcriptional modifications (PTMs) may play a significant role in defining host-virus interactions. The model system consisted of a yeast strain capable of harboring the endogenous L-A virus, which allowed me to evaluate the possible involvement of PTMs in the process of cellular immunity to virus-borne toxicity. A mass spectrometry-based platform was utilized to compare the global PTM profile of wild-type yeast with those of the same …
