Article Synopsis
- The study aimed to assess the clinical features and outcomes of pneumococcal meningitis in children under 16 in Lima, Peru, analyzing cases from 2006 to 2011.
- Out of 44 cases, a significant 68.2% involved children under 2 years old, with a high fatality rate of 32.6%, mostly within the first two days; malnutrition also correlated with fatalities.
- Over 40% of pneumococcal strains showed resistance to penicillin, with common serotypes being 6B, 14, 19F, and 23F, emphasizing the need for prompt diagnosis and effective vaccination.
Objectives: To determine the pattern of antibiotic susceptibility of isolated Streptococcus pneumoniae strains of healthy nasopharyngeal carriers younger than 2 years in seven regions of Peru.
Materials And Methods: Between 2007 and 2009, nasopharyngeal swab samples were collected among 2123 healthy children aged 2-24 months in growth and development medical practices (CRED) and vaccination offices of hospitals and health centers in Lima, Piura, Cusco, Abancay, Arequipa, Huancayo, and Iquitos. The resistance to ten antibiotics through disk diffusion sensitivity testing of isolated pneumococcus strains was determined.

Objectives: To determine the carriage rate and serotype distribution of Streptococcus pneumoniae in the nasopharynx of healthy children younger than 2 years prior to the universal use of the pneumococcal conjugate vaccines in Peru.
Materials And Methods: Between 2007 and 2009 we collected nasopharyngeal swab samples from 2,123 healthy children aged 2 to 24 months in the vaccination and healthy children consultation offices of pediatric hospitals and health centers in 7 cities in Peru: on the coast (Lima, Piura), highlands (Cusco, Abancay, Arequipa and Huancayo) and amazon basin (Iquitos). The pneumococcal strains were isolated and identified at the central laboratory of the project in Lima, and serotyped by Quellung reaction in the pneumococcal reference laboratory at the Center for Diseases Control and Prevention (CDC).

Objective: To determine the epidemiology of invasive pneumococcal disease (IPD) and the antibiotic susceptibility and serotype distribution of S. pneumoniae in pediatric patients in Lima, Peru.
Methods: A 2-year, multicenter, passive surveillance study conducted from May 2006- April 2008 in 11 public hospitals and five private laboratories in Lima, Peru, in patients less than 16 years of age with sterile site cultures yielding S.
