Distributions and Annual Changes of Streptococcus pneumoniae Serotypes Causing Infections in Adult Patients: Eight Years of US Surveillance (2009–2016)

Evaluation of Prevalence of S. pneumoniae pharyngeal carriers under 5 years of age by lytA gene detection

ABSTRACT          Background and Objective: Streptococcus pneumoniae is one of the leading causes of death among children worldwide. Nasopharyngeal colonization in children can spread pneumococcal infections in the community. This study aimed to evaluate the prevalence of S. pneumoniae strains isolated from healthy pharyngeal carriers less than 5 yea...

Yearly Trends of Antimicrobial Non-susceptibility among Streptococcus pneumoniae Serotypes Causing Infections in Adult Patients in the United States (2009–2015)

Distribution of 13-valent pneumococcal conjugate vaccine Streptococcus pneumoniae serotypes in US adults aged ≥50 years with community-acquired pneumonia.

BACKGROUND Streptococcus pneumoniae causes a substantial proportion of community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP) in the United States. Limited data are available regarding the pneumococcal serotypes causing CAP and HCAP. METHODS Adults aged ≥ 50 years presenting to participating US hospitals with radiographically confirmed pneumonia between February 2010 an...

Ten-year surveillance of pneumococcal infections in Temuco, Chile: implications for vaccination strategies.

We monitored Streptococcus pneumoniae serotypes causing invasive infections in patients admitted to one hospital in southern Chile during a 10-year period (1994 to 2004). All specimens isolated from patients with invasive S. pneumoniae infections were serotyped at the CDC in Atlanta, GA. A total of 508 isolates belonged to 58 serotypes. There were 95 infections in patients <2 years old, 33 infe...

Serotyping of Streptococcus pneumoniae isolated from Tehran by Multiplex PCR: Are serotypes of clinical and carrier isolates identical?

BACKGROUND AND OBJECTIVES Streptococcus pneumoniae is the most common cause of invasive infections among both young children and elderly people. Common serotypes causing invasive diseases and the emergence of carriers of Streptococcus pneumoniae in Iran is not yet known. Past-vaccine surveillance studies of serotype prevalence patterns in Iran are necessary to monitor the epidemiology of Strept...
