Widespread antibiotic resistance has quickly become one of the most concerning crises affecting modern medicine, especially in cases of Staphylococcal infections, which have become resistant to all ��-lactam antibiotics. As a result, research into alternative forms of treatment for bacterial infections is a top priority. Bacteriophage therapy is a popular candidate for replacing antibiotics, due to the way the viruses interact with the bacteria. The 80�� prophage integrates its DNA into Staphylococcus aureus strain 10616 via the lysogenic cycle, and replicates with the bacterial cell. When stressed, the bacteria stop replicating and the prophage stimulates the lytic cycle, activating transcription …

Macrophages are a key leukocyte in defense against Mycobacterium tuberculosis infection. The precise mechanism by which M. tuberculosis evades host macrophage defenses remains unknown, so understanding how macrophages interact with cell wall components of mycobacteria is critical. Lipoarabinomannan (LAM) is a glycolipid Toll-like receptor-2 (TLR-2) ligand found on the cell wall of mycobacteria, and is thought to contribute to the cell wall structural integrity. When LAM binds to TLR on host leukocytes, this activates cellular responses and phagocytosis by host macrophages. Nitric oxide production can be used as a measure of inflammatory response and can be evaluated via nitrite response …
