is engaged in teaching and research in bacteriology, mycology and parasitology.
Main research projects include studies on pathogenesis in experimental
and natural infections, characterization of microbes and virulence factors,
experimental vaccine studies, immuno-based diagnostics, microbial metabolites
and public health microbiology. Focus is particularly put on the human
gastric pathogen Helicobacter pylori as regards pathogenesis and
new immuno- and PCR-based diagnostic methods, pathogenesis and biological
effects of staphylococcal and streptococcal infections and methods to
prevent infections. Another major research area is in the field of public
health microbiology involving studies on air-borne microorganisms in relation
to diseases and symptoms in indoor environments where new chemical-analytical
methods are developed and applied.
Wadström heads a research group working on ”Microbial
pathogenesis and development of immuno- and PCR-based diagnostic methods”.
He has been engaged in research on Bangladesh, India, Singapore and Sri
Lanka. Åsa Ljungh heads a
research group on ”Pathogenesis of staphylococcal infections and
methods to prevent infections”. She has mostly worked on Vietnam
but also to some extent India.
Associate Professor Lennart
Larsson, heads the research group on ”Microbial chemical
markers”. He has also been engaged in some research focused on India.
Research and Collaboration with South Asia
Collaboration is taking place with various institutes in the developing
countries. Masters and PhD students are trained through courses in medical
microbiology and laboratory research methods. In return Swedish students
visit research centers in these countries. The collaborating partners
in South Asia have been: Professor Eric Karunanayake,
Faculty of Medicine, University of Colombo,
Sri Lanka; Professor Neena Sandhu,
Smt. Chandibai Himathmal Mansukhani College,
Thane, India; and Dr S A Sarker and
M J Albert, International
Center for Diarrheal Diseases Research (ICDDR,B) in Dhaka, Bangladesh.
Torkel Wadström is involved in
a research project on ”Effects of environmental
stress on the production of cell surface proteins and of regulatory and
virulence genes by gastrointestinal pathogens (Helicobacter species) and
by Lactic Acid Bacteria with relevance for the pathogenesis of chronic
infections as well as for applications in the food industry”.
The project is carried out in collaboration with Dr. Rukhsana
Chowdhury, Assistant Director of the Indian Institute of Chemical
Biology in Kolkata, India; and Professor Jashbhai
B Prajapati, Dept. of Dairy Science, Anand Agricultural University,
Gujarat, India. The project was given a SASNET
Planning grant in February 2005.
Dr. Chowdhury visited Lund in September 2005 in connection with the research
project. She also visited SASNET root node office, see the photo to
the right of her along with Prof. Mattiasson.
Three postdocs from India joined Åsa Ljungh’s and Torkel Wadström’s research group in 2009.
– Dr. Padma Ambalam comes from the National Dairy Research Institute Deemed University in Karnal, Haryana. Padma has been to Lund University once before for a 3 month stay. Her superior at the the National Dairy Research Institute, Prof J B Prajapati also returned to Lund University for a short visit in April-May 2009. Padma characterizes Lactic Acid Bacteria in a new European Commission-funded project that is run by the department.
– Dr. Amit Baidya comes from Indian Institute of Chemical Biology in Kolkata, the departmentthat has collaborated for many years with Prof Rukhsana Chowdury (see above). Amit studies stress responses in bacteria, with emphasis on Lactic Acid Bacteria, also in the European Commission-funded project.
– Dr. Kanthi Kiran, from the Indian Institute of Technology Madras (IITM) in Chennai. With a strong background biochemistry, biotechnology and bioanalytical techniques he will be of great value in two projects and transfer knowledge to the rest of the group. He is part of the European Commission-funded project and among other items study adhesion to various surfaces.
European Study Group on Pathogenesis and Immunology in Helicobacter
Prof. Wadström is one of the two Chairmen of the Executive Committee
European Study Group on Pathogenesis and Immunology
in Helicobacter Infections,
to the European Helicobacter Study Group, EHSG). It
was founded in 1992 as the European Pathogenesis and Immunology Study
Group by scientists working on Helicobacter infections with the main
purpose of stimulating collaboration between groups. One approach to
realize this goal is to arrange basic science meetings on pathogenesis,
immunology, and genetics. Pathophysiology, diagnosis, antimicrobial agents
and susceptibility testing are not the main subjects for the meetings
although they may be borderlines to the fields. ESGPIHI regularly organises
International workshops. Over the years,
they have developed into international meetings with interaction
between invited specialists presenting keynote lectures and young scientists
presenting original work. The 2006 workshop took place in Helsingør
