LEON, María Eugenia et al. Frequency of Streptococcus pneumoniae isolated from invasive disease in Paraguay, serotypes and sensitivity profile (2010-2018). Mem. Inst. Investig. Cienc.

Streptococcus pneumoniae remains one of the most important causes of morbidity and mortality in children and adults worldwide. The objective of the study was to describe the frequency of isolation of S. pneumoniae in invasive disease, serotype distribution and antimicrobial susceptibility in Paraguay (2010-2018). We studied 793 strains of S. pneumoniae isolated from patients of all ages with invasive disease in Paraguay, from different sentinel centers and collaborators in the framework of meningitis and pneumonia surveillance during the period 2010-2018. The general frequency according to diagnosis was 74.9% of pneumonia (n = 594), 18.4% of meningitis (n = 146) and 6.7% of sepsis (n = 53). Serotype 14 was more frequent with 174 isolates (22.0%), followed by serotype 19A with 84 isolates (10.6%), serotype 3 with 66 isolates (8.3%) and 6A with 37 isolates (4.70%). In meningitis, there was a general frequency of penicillin resistance of 32.2% and ceftriaxone of 1.4%. In cases of non-meningitis, penicillin resistance was 0.8% and ceftriaxone 0.3%. The results of serotypes and antimicrobial sensitivity will provide necessary information for the implementation of prevention strategies and treatment of pneumococcal disease in our country, therefore it is necessary to continue monitoring in order to assess the burden of the disease, circulating serotypes and increased antibiotic resistance.
