Summary
MRSA is a major cause of hospital-acquired infection. Molecular typing identifies how a patient managed to contract MRSA in the hospital, and if the strain they have is particularly dangerous. This study will develop a rapid typing protocol then implement it routinely, to determine whether providing this information to infection control staff in a more timely fashion will lead to reduced MRSA infections in hospitals.
Identification And Analysis Of Novel Replication Initiation Factors In Staphylococcus Aureus

Summary
Multi-drug resistant Golden staph is a serious medical problem around the world because strains are often resistant to commonly used treatments; new drugs are therefore urgently required. DNA replication is a fundamental process that is essential for the survival of all cellular organisms. This project aims to identify and characterise novel factors involved in DNA replication in Golden staph, which represent potential drug targets.

Summary
At present, treatment of leukaemia is based either on established chemotherapeutic drug treatment or newly identified inhibitor drugs currently being tested as part of clinical trials. Both these treatments are known to induce or select for resistance to the drugs in some cases. Resistance usually reduces the success rate of any further treatment with the same or similar drugs. To discover possible ways of overcoming drug resistance it is important to understand the mechanisms that are responsib ....At present, treatment of leukaemia is based either on established chemotherapeutic drug treatment or newly identified inhibitor drugs currently being tested as part of clinical trials. Both these treatments are known to induce or select for resistance to the drugs in some cases. Resistance usually reduces the success rate of any further treatment with the same or similar drugs. To discover possible ways of overcoming drug resistance it is important to understand the mechanisms that are responsible. To date a number of mechanisms that cause resistance are known, but there are still unidentified mechanisms that are associated with drug resistance. The aim of our work is to use a new method to identify unknown drug resistance mechanisms in leukaemia. Once a mechanism is identified, we will determine its relevance in leukaemia by screening a number of patients that have shown resistance to treatment. If identified as a common mechanism of resistance in leukaemic patients, we will test possible agents able to prevent drug resistance that could be used in conjunction with drug during treatment, and to screen new drugs for susceptibility to resistance mechanisms. Diagnostic tests to detect the presence of the known resistance mechanisms prior to treatment could be used in selection of the most appropriate drug combinations for individual patients. Some of the known drug resistance mechanisms that occur in leukaemia are also operative in other forms of cancer and the project is of general relevance to cancer chemotherapy.Read moreRead less
