Emergence of a Streptococcus dysgalactiae subspecies equisimilis stG62647-lineage associated with severe clinical manifestations
Oppegaard, Oddvar; Mylvaganam, Haima; Skrede, Steinar; Lindemann, Paul Christoffer; Kittang, Bård Reiakvam (Peer reviewed; Journal article, 2017-08-08)Increasing incidence rates of invasive Streptococcus dysgalactiae subspecies equisimilis (SDSE) infections have been reported worldwide, but the evolutionary mechanisms underlying this development remain elusive. Through ... -
emm gene diversity, superantigen gene profiles and presence of SlaA among clinical isolates of group A, C and G streptococci from western Norway
Kittang, Bård Reiakvam; Skrede, Steinar; Langeland, Nina; Haanshuus, Christel Gill; Mylvaganam, Haima (Peer reviewed; Journal article, 2010-11-20)In order to investigate molecular characteristics of beta-hemolytic streptococcal isolates from western Norway, we analysed the entire emm gene sequences, obtained superantigen gene profiles and determined the prevalence ... -
Increased cytotoxicity and streptolysin O activity in group G streptococcal strains causing invasive tissue infections
Siemens, Nikolai; Kittang, Bård Reiakvam; Chakrakodi, Bhavya; Oppegaard, Oddvar; Johansson, Linda; Bruun, Trond; Mylvaganam, Haima; Svensson, Mattias; Skrede, Steinar; Norrby-Teglund, Anna (Peer reviewed; Journal article, 2015)Streptococcus dysgalactiae subsp. equisimilis (SDSE) has emerged as an important cause of severe skin and soft tissue infections, but little is known of the pathogenic mechanisms underlying tissue pathology. Patient samples ... -
Temporal trends of β-haemolytic streptococcal osteoarticular infections in western Norway
Oppegaard, Oddvar; Skrede, Steinar; Mylvaganam, Haima; Kittang, Bård Reiakvam (Peer reviewed; Journal article, 2016-10-04)Background: Beta-haemolytic streptococci are important contributors to the global burden of osteoarticular infections (OAI). Knowledge on the disease traits specific for streptococcal OAI, however, remains scarce. We wished ... -
Use of microbiology tests in the era of increasing AMR rates- a multicentre hospital cohort study
Skodvin, Brita; Wathne, Jannicke Slettli; Lindemann, Paul Christoffer; Harthug, Stig; Nilsen, Roy Miodini; Charani, Esmita; Syre, Heidi; Kittang, Bård Reiakvam; Kleppe, Lars Kåre Selland; Smith, Ingrid (Peer reviewed; Journal article, 2019-02-04)Background: Effective use of microbiology test results may positively influence patient outcomes and limit the use of broad-spectrum antibiotics. However, studies indicate that their potential is not fully utilized. We ...
