Pietro Mastroeni

Pathogenesis and immunobiology of bacterial infections

My current research develops and applies multidisciplinary approaches to unravel the links between in vivo pathogen behaviour (location, division, death, gene regulation and spread), immunity, immunoevasion and the efficacy of vaccines and antibiotics. We are currently extending our research to clinical setting to understand immunological risk factors that increase susceptibility to invasive bacterial infections; this will support the development and evaluation of vaccines for African children.

    My research uses a large number of innovative techniques and tools that when combined together allow us to study how the behaviour of bacteria within the host tissues can affect the efficacy of vaccines and of treatment with antibiotics. This will eventually allow more accurate and rapid targeting of the bacteria at the sites where they grow and persist in the body, thus reducing collateral damage and minimising the chances of development of antimicrobial resistance. We have also been involved in the recent testing of new generations of vaccines against invasive bacterial diseases, such as septicaemic Salmonella infections, that currently have a very high death toll in children, especially in Africa. Our research is gradually moving into clinical settings to understand which vaccines are best for those areas of the world where the immune system of a vaccinee may be partially impaired by concurrent co-morbidities such as malaria, malnutrition, HIV etc.
