Polysaccharide conjugate vaccine against pneumococcal pneumonia in adults.

New England Journal of Medicine, 2015
BACKGROUND Pneumococcal polysaccharide conjugate vaccines prevent pneumococcal disease in infants, but their efficacy against pneumococcal community-acquired pneumonia in adults 65 years of age or older is unknown. METHODS In a randomized, double-blind,

Hopf-bifurcation analysis of pneumococcal pneumonia with time delays [PDF]

arXiv, 2019
In this paper, a mathematical model of pneumococcal pneumonia with time delays is proposed. The stability theory of delay differential equations is used to analyze the model. The results show that the disease-free equilibrium is asymptotically stable if the control reproduction ratio R0 is less than unity and unstable otherwise.

Identifying Infection Sources and Regions in Large Networks [PDF]

, 2012
Identifying the infection sources in a network, including the index cases that introduce a contagious disease into a population network, the servers that inject a computer virus into a computer network, or the individuals who started a rumor in a social network, plays a critical role in limiting the damage caused by the infection through timely ...

Nasopharyngeal S. pneumoniae carriage and density in Belgian infants after 9 years of pneumococcal conjugate vaccine programme [PDF]

, 2018
Background: In Belgium, the infant pneumococcal conjugate vaccine (PCV) programme changed from PCV7 (2007-2011) to PCV13 (2011-2015) and to PCV10 (2015-2016). A 3-year nasopharyngeal carriage study was initiated during the programme switch in 2016.

Risk of invasive pneumococcal infections among working age adults with asthma

Thorax, 2010
Background Information about the risk of invasive pneumococcal infection (IPI) among adults with asthma is limited and inconsistent. To evaluate this association, a population-based case–control study was conducted.

Risk modelling the mortality impact of antimicrobial resistance in secondary pneumococcal pneumonia infections during the 2009 influenza pandemic

International Journal of Infectious Diseases, 2019
Objectives: The aim of this study was to estimate the impact of antimicrobial resistance (AMR) in secondary pneumococcal pneumonia infections on global mortality during the 2009 influenza pandemic, to estimate future pandemic mortality risk and to inform

The contact process with semi-infected state on the complete graph [PDF]

arXiv, 2017
In this paper we are concerned with the contact process with semi-infected state on the complete graph $C_n$ with $n$ vertices. In our model, each vertex is in one of three states that `healthy', `semi-infected' or `wholly-infected'. Only wholly-infected vertices can infect others. A healthy vertex becomes semi-infected when being infected while a semi-

Molecular epidemiology of pneumococci obtained from Gambian children aged 2-29 months with invasive pneumococcal disease during a trial of a 9-valent pneumococcal conjugate vaccine. [PDF]

, 2008
BACKGROUND: The study describes the molecular epidemiology of Streptococcus pneumoniae causing invasive disease in Gambian children METHODS: One hundred and thirty-two S. pneumoniae isolates were recovered from children aged 2-29 months during the course

Evolution of antimicrobial resistance and serotype distribution of Streptococcus pneumoniae isolated from children with invasive and noninvasive pneumococcal diseases in Algeria from 2005 to 2012

New Microbes and New Infections, 2015
Pneumococcal infections are a major cause of morbidity and mortality in developing countries. The introduction of pneumococcal conjugate vaccines (PCVs) has dramatically reduced the incidence of pneumococcal diseases. PCVs are not currently being used in
