1. Monocyte responses during bacterial infection and carriage in the airways.
2. Local and systemic antibody responses to Mycoplasma pneumoniae infection of and carriage on the respiratory tract.
3. Host-pathogen interactions during early onset sepsis in premature neonates.
4. Alternative treatments for respiratory infections with antibiotic-resistant bacteria.
The very direct link with the clinic is of great value. Together with Prof. Dr. A.M.C. van Rossum, Pediatrician/Infectiologist, and Dr. H. M. Janssens, Pediatrician/Pulmonologist, we work in a bidirectional approach: key questions from the clinic concerning pathology, diagnosis and treatment of pneumonia and Cystic Fibrosis are translated to an experimental setting. Additionally, we collaborate with national and international groups to facilitate these basic and translational studies.
Stop Spread Bad Bugs
“The Infection & Immunity (InZi) group, led by Dr. Wendy Unger, received two grants for research on increasing antibiotic resistance, one of which is funded by the Horizon Europe – Marie Skłodowska-Curie Actions (GA N⁰101073263). Effective treatment of bacterial infections is threatened by increasing resistance to antibiotics. Moreover, the treatment of an infection with a resistant bacterium is complex, lengthy, and prone to serious side effects. Therefore, the development and use of alternative agents, such as human milk oligosaccharides (a specific group of carbohydrates) and antimicrobial proteins, are urgently needed.
The Stop Spread Bad Bugs (SSBB) project is a new multidisciplinary research/training consortium created to combat the alarming problem of global antimicrobial resistance. A unique advanced education/training pipeline for 15 PhD students will be developed by seven academic and seven SME partners with complementary expertise in developing and testing novel approaches to antimicrobial therapy in humans. To this end, experts from drug development, infectiology, immunology and pharmacology, computational modeling, and imaging have been brought together to investigate whether the new drugs qualify as alternative treatments for bacterial infections in patients as a stand-alone therapy or as antibiotic adjuvant therapy (see https://ssbb-project.eu/).
Besides Dr. Wendy Unger, also several Erasmus MC colleagues, namely Dr. Laura Mezzanotte (Radiology & Nuclear Medicine), Dr. John Hays (Medical Microbiology and Infectious Diseases), Dr. Hettie Janssens (Pediatric Lung Diseases), and Prof. Dr. Annemarie van Rossum (Pediatric Infectiology), are involved in the SSBB research.”
