    Comparison of Serotype Prevalence of Pneumococci Isolated from Middle Ear, Lower Respiratory Tract and Invasive Disease Prior to Vaccination in Iceland 
    Hjálmarsdóttir, Martha Ásdís; Quirk, Sigríður Júlía; Haraldsson, Gunnsteinn; Erlendsdóttir, Helga; Haraldsson, Ásgeir; Kristinsson, Karl G. (Public Library of Science (PLoS), 2017-01-26)
    Background Information on pneumococcal serotype distribution before vaccination is a prerequisite for evaluation of vaccine effect. The aim was to investigate the prevalence of pneumococcal serotypes isolated from middle ear (ME), lower respiratory ...

    The Effect of the 10-Valent Pneumococcal Nontypeable Haemophilus influenzae Protein D Conjugate Vaccine on H. influenzae in Healthy Carriers and Middle Ear Infections in Iceland 
    Sveinsdóttir, Hildigunnur; Björnsdóttir, Jana Birta; Erlendsdóttir, Helga; Hjálmarsdóttir, Martha Ásdís; Hrafnkelsson, Birgir; Haraldsson, Ásgeir; Kristinsson, Karl G.; Haraldsson, Gunnsteinn (American Society for Microbiology, 2019-05-08)
    Vaccinations with the 10-valent pneumococcal conjugated vaccine (PHiD-CV) started in Iceland in 2011. Protein D (PD) from H. influenzae, which is coded for by the hpd gene, is used as a conjugate in the vaccine and may provide protection against ...

    Effect of Vaccination on Pneumococci Isolated from the Nasopharynx of Healthy Children and the Middle Ear of Children with Otitis Media in Iceland 
    Quirk, Sigríður Júlía; Haraldsson, Gunnsteinn; Erlendsdóttir, Helga; Hjálmarsdóttir, Martha Ásdís; van Tonder, Andries J.; Hrafnkelsson, Birgir; Sigurdsson, Samuel; Bentley, Stephen D.; Haraldsson, Ásgeir; Brueggemann, Angela B.; Kristinsson, Karl G. (American Society for Microbiology, 2018-09-26)
    Vaccination with pneumococcal conjugate vaccines (PCVs) disrupts the pneumococcal population. Our aim was to determine the impact of the 10-valent PCV on the serotypes, genetic lineages, and antimicrobial susceptibility of pneumococci isolated from ...

    Genomic Analyses of >3,100 Nasopharyngeal Pneumococci Revealed Significant Differences Between Pneumococci Recovered in Four Different Geographical Regions 
    van Tonder, Andries J.; Bray, James E.; Jolley, Keith A.; Jansen van Rensburg, Melissa; Quirk, Sigríður Júlía; Haraldsson, Gunnsteinn; Maiden, Martin; Bentley, Stephen D.; Haraldsson, Ásgeir; Erlendsdóttir, Helga; Kristinsson, Karl G.; Brueggemann, Angela B. (Frontiers Media SA, 2019-02-25)
    Understanding the structure of a bacterial population is essential in order to understand bacterial evolution. Estimating the core genome (those genes common to all, or nearly all, strains of a species) is a key component of such analyses. The size and ...

    A homozygous loss-of-function mutation leading to CYBC1 deficiency causes chronic granulomatous disease 
    Arnadottir, Gudny; Norðdahl, Guðmundur L.; Gudmundsdottir, Steinunn; Ágústsdóttir, Arna B.; Sigurðsson, Snævar; Jensson, Brynjar Örn; Bjarnadóttir, Kristbjörg; Theodórs, Fannar; Benonisdottir, Stefania; Ívarsdóttir, Erna V.; Oddsson, Asmundur; Kristjánsson, Ragnar P.; Sulem, Gerald; Alexandersson, Kristján F.; Júlíusdóttir, Þórhildur; Guðmundsson, Kjartan R.; Sæmundsdóttir, Jóna; Jónasdóttir, Aðalbjörg; Jónasdóttir, Áslaug; Sigurðsson, Ásgeir; Manzanillo, Paolo; Guðjónsson, Sigurjón Axel; Thorisson, Gudmundur A.; Magnússon, Ólafur Þ.; Másson, Gísli; Örvar, Kjartan B.; Holm, Hilma; Björnsson, Sigurður; Arngrimsson, Reynir; Gudbjartsson, Daniel; Thorsteinsdottir, Unnur; Jonsdottir, Ingileif; Haraldsson, Ásgeir; sulem, patrick; Stefansson, Kari (Springer Science and Business Media LLC, 2018-10-25)
    Mutations in genes encoding subunits of the phagocyte NADPH oxidase complex are recognized to cause chronic granulomatous disease (CGD), a severe primary immunodeficiency. Here we describe how deficiency of CYBC1, a previously uncharacterized protein ...

    Impact of the 10-valent pneumococcal conjugate vaccine on antimicrobial prescriptions in young children: a whole population study 
    Eyþórsson, Elías; Sigurdsson, Samuel; Hrafnkelsson, Birgir; Erlendsdóttir, Helga; Haraldsson, Ásgeir; Kristinsson, Karl G. (Springer Science and Business Media LLC, 2018-10-04)
    Background: Antimicrobial resistance is a public-health threat and antimicrobial consumption is the main contributor. The ten-valent pneumococcal conjugate vaccine (PHiD-CV10) was introduced into the Icelandic vaccination program in 2011. The aim ...

    Impact of the 10-valent pneumococcal conjugate vaccine on hospital admissions in children under three years of age in Iceland 
    Sigurdsson, Samuel; Eyþórsson, Elías; Erlendsdóttir, Helga; Hrafnkelsson, Birgir; Kristinsson, Karl G.; Haraldsson, Ásgeir (Elsevier BV, 2020-03-10)
    Introduction: Pneumococcus is an important respiratory pathogen. The 10-valent pneumococcal vaccine (PHiD-CV) was introduced into the Icelandic vaccination programme in 2011. The aim was to estimate the impact of PHiD-CV on paediatric hospitalisations ...

    Increase in tympanostomy tube placements despite pneumococcal vaccination, a population-based study 
    Eyþórsson, Elías; Sigurdsson, Samuel; Erlendsdóttir, Helga; Hrafnkelsson, Birgir; Kristinsson, Karl G.; Haraldsson, Ásgeir (Wiley, 2019-01-22)
    Aim: The aim was to estimate the impact of the 10-valent pneumococcal vaccine (PHiD-CV) on tympanostomy tube placements (TTP) in children under five years of age in Iceland. Methods: This population-based observational cohort study followed 11 consecutive ...
