Adenoidectomy and nasopharyngeal carriage of Streptococcus pneumoniae in young children

Archives of Disease in Childhood, 2010
The effect of adenoidectomy on nasopharyngeal colonisation of pathogens has not previously been evaluated. The authors studied the effect of adenoidectomy on nasopharyngeal colonisation by bacteria causing otitis media and the effect of adenoidectomy on the development of pneumococcal capsular polysaccharide antibodies.Randomised controlled study ...

The Impact of Pneumococcal Conjugate Vaccines on Serotype 19A Nasopharyngeal Carriage

Expert Review of Vaccines, 2019
Introduction: By preventing nasopharyngeal carriage acquisition among vaccinated persons, and thus reducing transmission, pneumococcal conjugate vaccines (PCVs) provide protection against pneumococcal vaccine serotypes among unvaccinated individuals.

Dynamics of nasopharyngeal pneumococcal carriage during the course of viral bronchiolitis

Pediatric Pulmonology, 2016
SummaryThe effect of viral infection on nasopharyngeal carriage of Streptococcus pneumoniae during childhood is not well known. We studied dynamics of pneumococcal colonization by quantitative PCR during the natural course of viral bronchiolitis. At time of admission, 47 (47%) of 100 patients with bronchiolitis carried pneumococci.

Tissue microbiota in nasopharyngeal adenoid and its association with pneumococcal carriage

Microbial Pathogenesis, 2021
The microbial colonization in the nasopharynx is a prerequisite for the onset of infectious diseases. For successful infection, pathogens should overcome host defenses as well as compete effectively with the resident microbiota. Hence, elucidating the richness and diversity of the microbiome at the site of pathogen colonization is pivotal.

Impact of azithromycin on oropharyngeal carriage of Group A Streptococcus and nasopharyngeal carriage of macrolide-resistant Streptococcus pneumoniae

The Pediatric Infectious Disease Journal, 2000
Invasive group A streptococcal (GAS) infections are a cause of serious morbidity and high mortality. There is a need for a simple, effective antimicrobial regimen that could be used to prevent invasive GAS disease in high risk situations. To assess azithromycin as a chemoprophylactic agent, we evaluated its efficacy for eradication of oropharyngeal (OP)

Epstein‐barr virus carriage by nasopharyngeal carcinoma in situ

International Journal of Cancer, 1993
AbstractWe studied the distribution of the EBV genome in tumour biopsies obtained from 42 patients with poorly differentiated or undifferentiated nasopharyngeal carcinoma (NPC) and 3 patients with well‐differentiated NPC. Six carcinoma in situ (CIS) foci were seen in 5 tumour specimens.

Pneumococcal Acute Otitis Media in Relation to Pneumococcal Nasopharyngeal Carriage

The Pediatric Infectious Disease Journal, 2005
Acute otitis media (AOM) is closely associated with viral upper respiratory tract infections, but the most common microbial agent found in the middle ear fluid during AOM is Streptococcus pneumoniae (Pnc). Pnc is also a common colonizer of the nasopharynx, and its prevalence is further increased during the viral infection.

The Effect of Rifampin on the Nasopharyngeal Carriage of Neisseria meningitidis in a Military Population

Journal of Infectious Diseases, 1971
(73.5% of the positive cultures) were isolated just after administration of the drug. This proportion of resistant strains dropped to approximately 30% by the time the study group departed. The carrier rate among a new group of trainees was 64.2%, and all 524 isolates were sensitive to rifampin. No rifampin-resistant organisms were isolated from any of

Pneumococcal protein PavA is important for nasopharyngeal carriage and development of sepsis

Molecular Oral Microbiology, 2010
Summary The pneumococcal cell surface protein PavA is a virulence factor associated with adherence and invasion in vitro. In this study we show in vivo that PavA is necessary for Streptococcus pneumoniae D39 colonization of the murine upper respiratory tract in a long-term carriage model, with PavA-deficient pneumococci being quickly cleared from ...
