Characterization and Fitness Cost of Tn7100, a Novel Integrative and Conjugative Element Conferring Multidrug Resistance in Haemophilus influenzae
Johannessen, Helene; Anthonisen, Inger Lill; Zecic, Nermin; Hegstad, Kristin; Ranheim, Trond Egil; Skaare, Dagfinn (Journal article; Tidsskriftartikkel, 2022-07-22)A multidrug-resistant (MDR) strain of Haemophilus influenzae, Hi-228, with phenotypic resistance toward ampicillin, cefotaxime, chloramphenicol, gentamicin, and azithromycin, was isolated in Oslo, Norway. The strain was part of a clonal outbreak (2016–2017) comprising five ST143 strains with identical resistotypes. Hi-228 carries a novel integrative and conjugative element (ICE), Tn7100, contributing ... -

Multilocus sequence typing and ftsI sequencing: a powerful tool for surveillance of penicillin-binding protein 3-mediated beta-lactam resistance in nontypeable Haemophilus influenzae
Skaare, Dagfinn; Anthonisen, Inger Lill; Caugant, Dominique A; Jenkins, Andrew; Steinbakk, Martin; Strand, Linda; Sundsfjord, Arnfinn; Tveten, Yngvar; Kristiansen, Bjørn-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)Background Beta-lactam resistance in Haemophilus influenzae due to ftsI mutations causing altered penicillin-binding protein 3 (PBP3) is increasing worldwide. Low-level resistant isolates with the N526K substitution (group II low-rPBP3) predominate in most geographical regions, while high-level resistant isolates with the additional S385T substitution (group III high-rPBP3) are common in Japan ...
