The main focus of my research is on beta haemolytic streptococci. Group A streptococci is one of the most common human pathogens. The disease spectrume is wide from mild tonsillitis to severe life-threathning conditions such as bacteremia. In addition to infections, Group A streptococci may colonize throat or skin asymtomatically. Carriage is significant factor for the spread of the bacteria.
Childbed fever of puerperal sepsis is a rare but severe disease condition that may develop after delivery. Group A streptococci is one of the common causatives of puerperal sepsis. The source of bacteria usually remains unknown.
Group B streptococci is another common human pathogen. It is transmitted from mother to newborn baby during the delivery. Bacteria may cause severe infection in the newbor as well as for the mother. In several countries, including Finland, Group B streptococci is screened from pregant women and treated before the delivery.
Academy of Finland has funded our research project on streptococci, pregancy and delivery. We have an ongoing clincal study in which we investigate the prevalence of asymptomatic carriage of beta haemolytic streptococci in pregnanct women and their partners. We investigate the identified streptococcal bacteria with several molecular techniques (such as whole genome sequencing, antimicrobial susceptility). In addition, we investigate the outcome of the pregnancy and delivery in relation to asymptomatic carriage of these bacteria.
Other research topics (in collab. with prof Jaana Vuopio) are epidemiology of group A streptococcal diseases (tonsillitis) and MRSA.
