The research at the Center for Infectious Medicine, CIM, is focused around studies of the human immune system and infection-immunity in humans. The Center operates within the Department of Medicine, Karolinska Institutet at the Karolinska University Hospital in Huddinge. CIM has since its inauguration in 2002 rapidly grown and gained national and international recognition. The vision is to become one of the leading translational research centers within immunity and infectious diseases in Europe.
Since many years, the Division of Infectious Diseases – connected to CIM – has been responsible for courses in Tropical Medicine, Vaccinology, etc. It has also been involved in collaboration on Shigella projects at ICDDR,B in Dhaka.

New methods of treatment of tuberculosis and HIV infection
Professor Jan Andersson, professor in Infectious Diseases at the Department of Medicine, Huddinge, has led a CIM research group focusing on ”
Jan Andersson is the Vice-President at Karolinska Institutet since January 2010.
The research group is now led by Assistant Professor Susanna Brighenti. In the group there is one post-doc researcher from India, P. Venkata Ramana Rao, with a PhD in Biochemistry and Immunology from the Tuberculosis Research Center in India in 2010); and a PhD candidate from Bangladesh, Sayma Rahman, working on a dissertation project entitled ”Dysfunctional effector T cells in human tuberculosis" since 2007.
Dr. Rubhana Raqib is a Scientist at the Immunology Unit within the Laboratory Sciences Division (LSD), ICDDR,B. She completed her PhD degree in October 1995 in a sandwich program between ICDDR,B and Karolinska Institutet, with SAREC/Sida funds and under PhD supervision from Professor Jan Andersson. She joined ICDDR,B immediately thereafter.

Dr. Raqib has been actively collaborating with Prof. Andersson in a number of Sida/SAREC funded studies. She has also become involved in new collaborations with other Swedish scientists in diverse fields, especially with Prof. Lars-Åke Persson, International Maternal and Child Health (IMCH), Department of Women’s and Children’s Health, Uppsala University. Her current research interests involve (i) alternative therapeutic strategies in combating infectious diseases, (ii) rapid diagnostic methods of tuberculosis, (iii) effects of maternal nutritional interventions on the immune function outcome of infants and children, (iv) effect of maternal exposure to toxic elements on the immune functions of infants.
The research in tuberculosis diagnostics has resulted in a Patent for an immunodiagnostic method of pulmonary tuberculosis.
Rubhana Raqib was invited as a key-note speaker in the SASNET workshop on ”The role of South Asia in the internationalisation of higher education in Sweden” held at Nobel Forum, Karolinska Institutet, Solna, 28-29 November 2006.

Disease mechanisms in severe acute bacterial infections
Professor Anna Norrby-Teglund leads a research group at CIM working on Disease mechanisms in severe acute bacterial infections. Streptococcus pyogenes is an important cause of severe invasive infections, such as toxic shock syndrome and necrotizing fasciitis, which are associated with high mortality rates despite adequate antimicrobial therapy. The research group includes one PhD candidate from India, Srikanth Mairpady Shambat, MSc in biomedical Genetics at Vellore Institute of Technology University.
In November 2008 Anna Norrby-Teglund received a Swedish Research Links (Asian–Swedish research partnership programme) one-year planning grant on 75 000 SEK for a new collaboration project with Indian colleagues, and in December 2009 she was awarded SEK 750 000 as a three-years grant. See the full list of South Asia related projects given Swedish Research Links gants 2009.
The project was titled ”
Abstract: The project aims to define the pathogenic mechanisms of meticillin-resistant Staphylococcus aureus (MRSA) with focus on the action of specific toxins, such as Panton Valentine leucocidin, superantigens and hemolysins. MRSA represent a significant health threat in both developing and developed countries. The incidences of these infections are rising, and unusually severe pathological signs have been associated with certain MRSA types, including necrotizing fasciitis and necrotizing pneumonia. There is a controversy within the field as to which toxins are the major players in the pathogenesis of these severe infections. Previous studies have used various murine infection models to compare virulence properties of isogenic toxin-deficient strains. Here the researcchers propose to use clinical isolates with the same genetic background, but with varying toxin profiles, in clinically relevant human cell and tissue model systems. The proposal is based on collaboration between India and Sweden. A large cohort of MRSA isolates collected in India will be used for studies of MRSA induced cell damage and inflammatory responses in in vitro human cell and tissue models. The project is likely to advance our understanding of the defined role of specific toxins in the destructive infections associated with MRSA. Such insight should promote identification of potential targets for intervention and thus promote development of novel therapeutic or prophylactic strategies.
Pathogenesis of Toxoplasma gondii infections (e.g. malaria)
Dr. Antonio Barragan (photo to the left) leads a group focusing on Pathogenesis of Toxoplasma gondii infections, integrating immunology with molecular parasitology to understand how obligate intracellular parasites evade and direct host immune systems to their own advantage. Their research aims to define the pathogenic mechanisms utilized by the opportunistic human pathogen Toxoplasma gondii and related apicomplexan parasites (malaria, cryptosporidium) to promote colonization and transmission of infection.
In November 2012 Dr. Antonio Barragan together with collaboration partner Md. Shahiduzzaman, Bangladesh Agricultural University, received a Swedish Research Links (Asian–Swedish research partnership programme) grant on SEK 600 000 for their project "Detection and characterization of the waterborne parasite Cryptosporidium in Bangladesh and Sweden". See the full list of South Asia related projects given Swedish Research Links gants 2012.
Project abstract: Cryptosporidium is a zoonotic pathogen posing a significant public health threat globally. It is an important cause of water and sanitation-related diarrheal disease worldwide. Despite major knowledge gaps in this area, the prevalence of cryptosporidiosis is generally considered higher in developing countries than in developed countries. Previous studies indicate that cryptosporidiosis may be a significant cause of diarrheal illness in Bangladesh, especially in young children. Outbreaks may also occur in developed countries, exemplified by two major outbreaks in Sweden in 2010-11. There is an overall need for improved epidemiological and diagnostic tools employed for the environmental/water survey and laboratory diagnosis of this parasitic disease. The proposed study will contribute to the elucidation of the prevalence of Cryptosporidium in water in Bangladesh. Molecular differentiation of Cryptosporidium species commonly found in animal faces or human feces will provide important epidemiological data and improved sensitivity and accuracy for human diagnostics. The execution of the project builds on reciprocal exchange at the methodological and educational levels. The results will provide important information to Health Authorities of both countries in respect of prevalence and spreading potential of this parasite. Furthermore, the establishment of methodologies for diagnostics and genetic characterizations of the parasite will aid in actions to be taken in outbreak situations.
