Antimicrobial resistance is a phenomenon in which microorganisms such as bacteria become resistant to drugs that were previously effective in eliminating or controlling their growth. According to the WHO, one of the priority pathogens needing an alternative therapy is methicillin-resistant Staphylococcus aureus (MRSA), due to its numerous pathogenic mechanisms, its ability to synthesize bioflms, and its unique clonal variation that allows it to spread and colonize new environments. Phage therapy has shown a broad approach to treating infections caused by this pathogen, given its high specifcity and effectiveness in killing the host bacteria. However, there are still some obstacles to its therapeutic use inhumans, requiring more clinical trials. This research article details cases and clinical studies that provide useful information, which can be complemented by subsequent clinical studie...

Immunotherapy as a treatment for cancer has developed considerably in recent years, proving to be a promising type of treatment against cancer. This therapy consists of the administration of substances produced by the body or through a laboratory, to help the immune system to accurately identify and eliminate neoplastic cells in the patient. The latest research proposes to improve the recognition of tumor antigens and to take advantage of the effector mechanisms of the individual's own immune cells; it also suggests directly stopping cancer cells, since they stimulate the immune system's capacity to recognize them byactivating defense mechanisms that prevent cancer proliferation. However, it remains a challenge to increase effectiveness, specifcity and safety, as this type of treatment is not without limitations and adverse effects. Among the types of immunotherapy currently available ar...
