Increase of resistance to macrolides in invasive Streptococcus pneumoniae in Spain (2000-2001).

Clin Microbiol Infect

Centro Nacional de Microbiología, 28220 Majadahonda, Madrid, Spain.

Published: September 2004

This study examined the antimicrobial resistance of 1,278 invasive Streptococcus pneumoniae isolates from 41 Spanish laboratories participating in the European Antimicrobial Resistance Surveillance System (EARSS) during 2000 and 2001. Twenty-nine laboratories participated during both years and provided 950 of the isolates. Each laboratory used its own susceptibility testing methods. External quality assessment was performed annually by each participating laboratory. Significant increases in penicillin and erythromycin resistance were observed between 2000 and 2001. This increase was particularly noticeable in isolates from the laboratories participating during both years and in isolates from children and elderly patients.

Invasive pneumococcal disease (IPD) is a serious global public health problem and the leading cause of morbidity and mortality in children and adults in China. Thus, developing and administering pneumococcal vaccines are important for disease prevention. The PPV23 and PCV13 vaccines are available in the Chinese market and are primarily produced by domestic manufacturers.

Bacterial meningitis is a severe and life-threatening infection of the central nervous system (CNS), primarily caused by and . This condition carries a high risk of mortality and severe neurological sequelae, such as cognitive impairment and epilepsy. Pain, a central feature of meningitis, results from the activation of nociceptor sensory neurons by inflammatory mediators or bacterial toxins.

Unlabelled: Oral squamous cell carcinoma (OSCC) is a prevalent malignancy in the oral-maxillofacial region with a poor prognosis. Oral microbiomes play a potential role in the pathogenesis of this disease. However, findings from individual studies have been inconsistent, and a comprehensive understanding of OSCC-associated microbiome dysbiosis remains elusive.

Introduction: Pneumococcal diseases (PD) caused by include invasive PD (IPD) and non-bacteremia pneumococcal pneumonia (NBPP). Current French vaccination guidelines FOCUS on patients with underlying medical conditions (UMC) who are at a higher risk of PD. This study describes the healthcare resource utilization (HCRU) and economic burden of inpatient PD in French adults, to inform vaccination guidelines, especially among vulnerable subpopulations at increased risk of PD.

Background: Due to high costs of pneumococcal conjugate vaccines (PCV), transitioning from a two (2 + 1) to a single dose (1 + 1) primary series with a booster should be considered. This study evaluated the immune response at 18 months of age following a 1 + 1 compared to a 2 + 1 schedule of 10-valent (PCV10) and 13-valent (PCV13) vaccines.

Research Design And Methods: A single-center, open-label, randomized trial conducted in Soweto, South Africa, evaluated the immunogenicity of differing dosing schedule for PCV10 and PCV13.
