    • C. difficile infection in children particularly oncology 
    • Candidemia in children
    • Fungal infection in immunocompromised hosts

    My current research is focused on Clostridium difficile infection in children with cancer. Clostridium difficile is a common bacterium in the human gut that usually does not cause infection but in certain circumstances can cause diarrhea. It is significant because it can easily spread from patient to patient in hospitals if infection prevention measures and environmental cleaning practices are suboptimal. We have noted that a higher proportion of oncology patients have this infection compared to other hospitalized patients. We aim to determine whether patients get the infection in hospital or if they come to the hospital with it. This information will help us understand the true burden of C. difficile infection in oncology and improve the quality of care provided to these patients.
    Current Projects

    Clostridium difficile in pediatric oncology

    • To determine the prevalence of C. difficile by PCR (toxin gene) in stools from pediatric oncology patients at admission to hospital 
    • To determine the true rate of health care associated C.  difficile infection and community-associated C.  difficile infection in pediatric oncology patients
    • Evaluate the evidence of patient to patient transmission based on typing of C. difficile isolates from pediatric oncology patients, using each patient as their own control
    • Determine the epidemiology of candidemia in adults and children
    • Determine the incidence of mixed candidemia 
    • Determine the correlation of antifungal susceptibility with clinical outcome
